     FIELD OF THE INVENTION 
     The present invention generally relates to collection devices. More specifically, the present invention is a collection device for debris and animal waste. 
     BACKGROUND OF THE INVENTION 
     Animal caretakers, groundskeepers, and pet owners must routinely clean up animal waste from animal enclosures, yards, and other areas where animals leave waste. For most responsible individuals, picking up animal waste requires them to handle the solid animal matter with either a glove or cumbersome apparatus. Often because the mechanical methods leave residual waste on the surface, water or some other liquid must be applied to remove the residual waste and sterilize the area to prevent the spread of harmful diseases, such as the Parvo virus. 
     Cleaning collection devices in this manner wastes water and can also contribute to the spread of animal waste and harmful chemicals in liquified form. While both situations offer disadvantages, current methods are generally considered to be time consuming, messy, unpleasant, and difficult in some cases. Furthermore, a practical handheld vacuum for outdoor use is in demand for grounds keepers to collect other types of small debris such as, but not limited to, cigarette butts, bottle caps, golf balls, tree acorns, and wild animal excrement from geese, deer, and farm animals. There are limited choices for these applications as well. 
     While the unpleasant job of handling animal waste is inescapable for responsible individuals and businesses, apparatuses have been designed and created to minimize the various negative aspects associated with cleaning up animal waste. The apparatuses developed for collecting solid animal waste can be largely placed into two categories distinguished by the approach to collection. The first category of apparatuses requires mechanical manipulation. Such devices typically require the user to position the apparatus appropriately and shovel the solid waste matter into the apparatus. The second category of apparatuses uses a mechanical component to siphon or vacuum the animal waste into a receptacle. Generally, the vacuum-type apparatuses do not provide features that would be truly effective for collecting pet waste in both indoor and outdoor settings. Thus, there is a need to develop a device to solve this problem. 
     It is therefore an objective of the present invention to address problems associated with and/or otherwise improve upon conventional devices. The present invention is an innovative vacuum device designed to provide a convenient, effective means for the collection of pet waste, wild animal excrement, and small debris, while incorporating other problem-solving features. The present invention is designed for the collection of animal feces or waste matter that is discharged from the bowels after food has been digested, also known as excrement. The present invention collects pet waste and animal waste for both indoor and outdoor settings. Examples of indoor settings include semi-enclosed kennels, animal pens, and other interior spaces where animals are kept.

     DETAILED DESCRIPTIONS OF THE INVENTION 
     All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention. 
     The present invention is a collection device for debris and animal waste. The present invention optimizes airflow in order to effectively collect debris, pet waste, and wild animal excrement in both indoor and outdoor areas. The present invention safely contains debris until the area is clear of debris or the canister  1  is full. The present invention limits or eliminates any direct contact between the hands of the user and the pet waste throughout collection. In order to collect debris, preferably animal waste, the present invention comprises a canister  1 , at least one handle assembly  18 , an airflow inlet nozzle  43 , a portable power source  50 , and a fan assembly  51 , seen in  FIG. 1 ,  FIG. 2 ,  FIG. 3 ,  FIG. 4 , and  FIG. 5 . The canister  1  houses the collected pet waste and fan assembly  51 . Furthermore, the canister  1  upholds the airflow inlet nozzle  43  and the portable power source  50 . The canister  1  comprises a cylindrical body  2 , a lid  6 , a debris hole  13 , a debris chamber  14 , and a suction chamber  15 . The cylindrical body  2  is a rigid body that contains the collected pet waste and the fan assembly  51  and defines the airflow into and out of the canister  1 . More specifically, the cylindrical body  2  comprises an inlet  3  and an outlet  4 . The airflow traverses into the canister  1  through the inlet  3  and exits the canister  1  through the outlet  4 . The lid  6  covers the inlet  3  and mounts the airflow inlet nozzle  43  with the cylindrical body  2 . The debris hole  13  provides passage for debris through the lid  6  and through the inlet  3 . The debris chamber  14  is the portion of the canister  1  that retains the collected pet waste. The suction chamber  15  is the portion of the canister  1  that houses the fan assembly  51  and separates the fan assembly  51  from the collected pet waste. 
     Furthermore, the at least one handle assembly  18  allows a user to maneuver the canister  1 , and consequently the airflow inlet nozzle  43  towards pet waste, seen in  FIG. 1 ,  FIG. 2 ,  FIG. 3 ,  FIG. 4 , and  FIG. 5 . The airflow inlet nozzle  43  directs the pet waster into the canister  1  as well as the suction of the airflow around targeted pet waste. The portable power source  50  provides the necessary power for the fan assembly  51  to operate. In the preferred embodiment of the present invention, the portable power source  50  is preferably a portable battery that may be recharged or replaced. The fan assembly  51  generates airflow which in turn creates a vacuum within the canister  1 . 
     The overall configuration of the aforementioned components allows a user to readily retrieve debris and animal waste without having to directly pick up the debris with hands. In order to provide a continuous flow of air through the canister  1 , the inlet  3  is positioned opposite the outlet  4  along the cylindrical body  2 , seen in  FIG. 5 . The lid  6  is hermetically attached across the inlet  3 , thereby channeling air flow into the canister  1  through the airflow inlet nozzle  43  and preventing any pet waste from falling out of the canister  1  after the pet waste has already been retrieved. The pet waste is directed by the airflow inlet nozzle  43  into the canister  1  as the debris hole  13  traverses through the lid  6 . In order for the airflow inlet nozzle  43  to siphon pet waste into the canister  1 , the airflow inlet nozzle  43  is externally positioned with the canister  1 . The airflow inlet nozzle  43  is hermetically attached into the debris hole  13 , thereby maintaining the continuous airflow into the canister  1 . In order prevent pet waste from coming into contact with the fan assembly  51 , the debris chamber  14  is positioned within the cylindrical body  2 , adjacent to the inlet  3 . Furthermore, the suction chamber  15  is positioned within the cylindrical body  2 , adjacent to the outlet  4 , maximizing the suction created by the airflow of the fan assembly  51 . The airflow remains continuous through the canister  1  as the inlet  3  is in fluid communication with the debris chamber  14 , the debris chamber  14  is in fluid communication with the suction chamber  15 , and the suction chamber  15  is in fluid communication with the outlet  4 . The airflow into the canister  1  therefore positions any collected pet waste into the debris chamber  14  before the suction chamber  15 . The fan assembly  51  is mounted within the suction chamber  15 , providing the debris chamber  14  enough space to contain pet waste. The at least one handle assembly  18  and the portable power source  50  is laterally mounted with the cylindrical body  2  in order for the user to easily access the at least one handle assembly  18  and the portable power source  50 . In order for the fan assembly  51  to generate airflow, the portable power source  50  is electrically connected with the fan assembly  51 . 
     In order for the airflow inlet nozzle  43  to be readily attached and detached with the lid  6 , the airflow inlet nozzle  43  comprises a nozzle body  44  and a rim  49 , seen in  FIG. 5 . The nozzle body  44  is a rigid extension for the lid  6  that targets the airflow around nearby pet waste. The nozzle body  44  comprises a first edge  45  and a second edge  46 . The first edge  45  engages with the lid  6 , and the second edge  46  surrounds pet waste. The rim  49  serves to connect the nozzle body  44  with the lid  6 . In order for the lid  6  to enclose the inlet  3 , the lid  6  comprises a lip  7 , a base wall  8 , and an adapter  9 . The canister  1  is flushed within the lid  6  as the lip  7  is fixed onto the base wall  8  and is peripherally positioned about the base wall  8 . The base wall  8  is positioned across the inlet  3 , thereby channeling air flow into the canister  1  through the airflow inlet nozzle  43  and stopping any collected pet waste from falling out of the canister  1 . In order for the base wall  8  to remain positioned across the entirety of the inlet  3 , the lip  7  is laterally positioned around the cylindrical body  2 . The pet waste enters the canister  1  as the debris hole  13  traverses through the base wall  8 . In order for the airflow inlet nozzle  43  to be engaged with the lid  6  and oriented towards pet waste, the adapter  9  is fixed onto the base wall  8 , opposite the lip  7  and is perimetrically positioned around the debris hole  13 . Pet waste traverses along and within the nozzle body  44  as the first edge  45  is positioned opposite the second edge  46  about the nozzle body  44 . The rim  49  is laterally fixed around the nozzle body  44 , adjacent with the first edge  45 , as the first edge  45  engages with the lid  6 . In order to maintain a secure connection between the airflow inlet nozzle  43  and the lid  6 , the rim  49  is engaged within the adapter  9 . In the preferred embodiment of the present invention a central axis  10  of the adapter  9  is oriented at an obtuse angle with a central axis  5  of the cylindrical body  2 . This arrangement angles the nozzle body  44  downwards towards selected pet waste. In order to facilitate the suctioning of the selected pet waste through the debris hole  13  and into the debris chamber  14 , the central axis  10  of the adapter  9  is positioned offset from the central axis  5  of the cylindrical body  2 . More specifically, the central axis  10  of the adapter  9  is positioned opposite the ground or elevated, preventing the debris hole  13  from being blocked by collected pet waste within the debris chamber  14 . Moreover, the first edge  45  is positioned normal to a central axis  48  of the nozzle body  44 . The second edge  46  is positioned at an angle  47  to the central axis  48  of the nozzle body  44 , facilitating the retrieval of pet waster along the ground. The canister  1  may remain slightly angled with the ground instead of oriented normal with the ground, directly on top of selected pet debris. 
     In a first embodiment of the present invention, the canister  1  further comprises a first latch mechanism  16  and a second latch mechanism  17 , seen in  FIG. 1 ,  FIG. 2 ,  FIG. 3 , and  FIG. 4 . The first latch mechanism  16  and the second latch mechanism  17  connect and disconnects the lid  6  with the cylindrical body  2 . The first latch mechanism  16  and the second latch mechanism  17  provide access into the canister  1 , specifically the debris chamber  14 , for removal of collected pet waste. As previously mentioned, the lid  6  comprises a lip  7 , a base wall  8 , and an adapter  9 . The lid  6  further comprises a first hook  11  and a second hook  12 . The first hook  11  connects the lip  7  with the first latch mechanism  16 . Similarly, the second hook  12  connects the lip  7  with the second latch mechanism  17 . In order to enclose the cylindrical body  2 , the lip  7  is fixed onto the base wall  8  and is peripherally positioned about the base wall  8 . The base wall  8  is positioned across the inlet  3 , thereby channeling air flow into the canister  1  through the airflow inlet nozzle  43  and stopping the collected pet waste from falling out of the canister  1 . In order for the base wall  8  to remain positioned across the entirety of the inlet  3 , the lip  7  is laterally positioned around the cylindrical body  2 . The lid  6  is evenly secured around the cylindrical body  2  as the first hook  11  and the second hook  12  are positioned opposite each other about the lip  7 . The first hook  11  and the second hook  12  are laterally fixed onto the lip  7 , preserving the arrangement of the lip  7  around the cylindrical body  2 . In order for the first latch mechanism  16  and the second latch mechanism  17  to be accessible by the user, the first latch mechanism  16  and the second latch mechanism  17  are laterally integrated into the cylindrical body  2 . In order for the first latch mechanism  16  and the second latch mechanism  17  to be aligned with the first hook  11  and the second hook  12 , respectively, the first latch mechanism  16  and the second latch mechanism  17  are positioned opposite each other about the cylindrical body  2 . The lid  6  may be connected and disconnected from the cylindrical body  2  as the first latch mechanism  16  is operatively coupled with the first hook  11 , wherein the first latch mechanism  16  is used to attach the first hook  11  to the cylindrical body  2  and is used to detach the first hook  11  from the cylindrical body  2 . Likewise, the second latch mechanism  17  is operatively coupled with the second hook  12 , wherein the second latch mechanism  17  is used to attach the second hook  12  to the cylindrical body  2  and is used to detach the second hook  12  from the cylindrical body  2 . The detachment of the first latch mechanism  16  or the detachment of the second latch mechanism  17  provides entry within the cylindrical body  2 . However, both the first latch mechanism  16  and the second latch mechanism  17  need to be detach simultaneously in order for the lid  6  to be completely separate from the cylindrical body  2 . 
     The cleaning of the present invention, specifically the canister  1 , is significantly minimized as the present invention further comprises an air-permeable collection bag  64 , seen in  FIG. 1  and  FIG. 5 . The air-permeable collection bag  64  serves as a protective layer for the debris chamber  14 . The air-permeable collection bag  64  prevents the collected pet waste from coming into contact with the debris chamber  14 . In order for the collected pet waste to be collectively removed from within the debris chamber  14  with the air-permeable collection bag  64 , the air-permeable collection bag  64  comprises a closed bag end  65  and an open bag end  66 . The closed bag end  65  covers the suction chamber  15 , protecting the fan assembly  51  from coming into contact with collected pet debris. The open bag end  66  allows the pet waste to enter into the air-permeable collection bag  64 , and consequently into the debris chamber  14 . In order for the pet waste to be suctioned into the cylindrical body  2 , the air-permeable collection bag  64  is positioned into the debris chamber  14  through the inlet  3 . The closed bag end  65  is positioned adjacent to the suction chamber  15 , stopping any collected pet waste from entering the suction chamber  15 . In order for the air-permeable collection bag  64  to not get dislodged and to be superimposed across the debris chamber  14 , the open bag end  66  is positioned around the inlet  3  and is pressed in between the lid  6  and the inlet  3 . 
     In a first embodiment of the present invention, the present invention further comprises a controller unit  67  and a trigger  68 , seen in  FIG. 5  and  FIG. 6 . The controller unit  67  process and manages each input from the trigger  68  in order to control the fan assembly  51 . The trigger  68  receives the manual input from a user to operate the fan assembly  51 . The trigger  68  provides a reference signal that changes as the trigger  68  is depressed. The controller unit  67  receives the reference signal and translates that into a motor speed control reference. The controller unit  67  then applies an appropriate level of voltage to the motor  55  of the fan assembly  51  to achieve the desired speed. Furthermore, the at least one handle assembly  18  comprises a clamp base  19 , a handlebar receiver  22 , a first fastener  27 , a handlebar  28 , and a handle grip  33 , seen in  FIG. 1 ,  FIG. 2 ,  FIG. 4 , and  FIG. 5 . The clamp base  19  serves as a mount for the handlebar receiver  22  with the canister  1 . The first fastener  27  secures and orients the handlebar receiver  22  with the clamp base  19 . The handlebar  28  connects the handle grip  33  with the handlebar receiver  22 . The handlebar  28  provides an ergonomic grip for the user to maneuver the canister  1  and engage the trigger  68 . The handle grip  33  is positioned offset from the canister  1  as the handlebar  28  comprises a proximal bar and a distal bar end  30 . The proximal bar end  29  connects the handlebar  28  with the handlebar receiver  22 . The distal bar end  30  receives and upholds the handle grip  33 . In order for the handlebar  28  to be connected with the canister  1 , the clamp base  19  is laterally mounted onto the cylindrical body  2 . The handlebar  28  is connected with the clamp base  19  as the handlebar receiver  22  is positioned adjacent with the clamp base  19 . The handlebar receiver  22  is rotatably connected with the clamp base  19 , allowing the handlebar  28  to be angled. More specifically, a rotation axis  31  of the handlebar receiver  22  is positioned perpendicular with a central axis  5  of the cylindrical body  2  such that the handlebar  28  is oriented along the central axis  5  of the cylindrical body  2  regardless of the angle of the handlebar  28  with the cylindrical body  2 . In order for the handlebar receiver  22  and, consequently, the handlebar  28  to be readily adjusted, the first fastener  27  is operatively coupled with the handlebar receiver  22  and the clamp base  19 , wherein the first fastener  27  is used to lock the handlebar receiver  22  in a selected orientation with the clamp base  19  and is used to unlock the handlebar receiver  22  from the selected orientation with the clamp base  19 . In order for the handlebar  28  to be maneuvered by the handlebar receiver  22 , the proximal bar end  29  is attached into the handlebar receiver  22 , opposite the clamp base  19 . The handle grip  33  is fixed adjacent with the distal bar end  30 , therefore positioning the handlebar  28  and, consequently, the handle grip  33  closer to the hand of the user. The control of the fan assembly  51  is quickly and easily engaged by the user as the trigger  68  is integrated into the handle grip  33 . The weight of the present invention is balanced as the controller unit  67  is mounted within the canister  1 , adjacent to the portable power source  50 . Moreover, this arrangement provides protection for the controller unit  67 . The controller unit  67  is electronically connected to the trigger  68  and the fan assembly  51 , thereby processing the inputs of the trigger  68  and controlling the rotational speed of the fan assembly  51 . In the preferred embodiment of the present invention, the trigger  68  adjusts the speed of the fan assembly  51  which in turn adjusts the amount of air flow generated by the fan assembly  51 . This assists the user in the collection of debris by being able to control the amount of suction applied. Furthermore, the variable speed of the fan assembly  51  increases and decreases the amount of power used by the fan assembly  51 , thus conserving limited battery power. In order for the controller unit  67  and the trigger  68  to operate, the portable power source  50  is electrically connected to the controller unit  67 , providing the necessary power for the controller unit  67 . It is understood that as the user progressively depresses the trigger, this action provides a control reference that signals the controller to increase the speed of the fan assembly  51 . 
     In order to turn on and turn off the portable power source  50  in the present invention and override any other controls, the present invention further comprises a power button  69 , seen in  FIG. 1 ,  FIG. 2 ,  FIG. 3 ,  FIG. 4 ,  FIG. 5 , and  FIG. 6 . The power button  69  disconnects the connection with the controller unit  67  and the fan assembly  51 . The power button  69  is accessible as the power button  69  is externally mounted onto the canister  1 , adjacent to the controller unit  67 . In order to for a user to disconnect and connect the flow of power with the fan assembly  51 , the power button  69  is electronically connected with the controller unit  67 . The power supply from the portable power source  50  is connected and disconnected with the power button  69  as the power button  69  is electrically connected with the portable power source  50 . 
     In order for the angle of the handlebar receiver  22  to be readily adjusted, in the preferred embodiment of the present invention, the clamp base  19  comprises a base plate  20  and a first mounting plate  21 . Furthermore, the handlebar receiver  22  comprises a socket member  23  and a second mounting plate  26 , seen in  FIG. 1 ,  FIG. 2 ,  FIG. 3 ,  FIG. 4 , and  FIG. 5 . The base plate  20  conforms around the cylindrical body  2  and the first mounting plate  21  provides a secure connection for clamp base  19  with the handlebar receiver  22 . Similarly, the socket member  23  conforms around the proximal bar end  29 . The second mounting plate  26  provides a stable secure connection for handlebar receiver  22  with the clamp base  19 . The handlebar receiver  22  and, consequently, the handlebar  28  to remain upright regardless of the angle between the handlebar  28  and the cylindrical body  2 , the first mounting plate  21  is positioned perpendicular to the base plate  20 . The first mounting plate  21  is fixed onto the base plate  20 , opposite the cylindrical body  2 , structurally reinforcing the clamp base  19 . In order for the handlebar  28  to be upheld with the socket member  23 , a closed socket end  24  of the socket member  23  is peripherally fixed with the second mounting plate  26 . The closed end stops the handlebar  28  from falling through the socket member  23 . The handlebar  28  is readily positioned into the socket member  23  as an open socket end  25  of the socket member  23  is positioned offset from the second mounting plate  26 . The open socket end  25  provides passage into the socket member  23  while preserving the structural integrity of the socket member  23 . The proximal bar end  29  is attached into the open socket end  25 , securing the connection of the handlebar  28  within the handlebar receiver  22 . The orientation of the handlebar  28  with the cylindrical body  2  is preserved as the first mounting plate  21  is laterally positioned with the second mounting plate  26 . The first mounting plate  21  is rotatably connected with the second mounting plate  26 . 
     In a second embodiment of the present invention, the handlebar  28  is extendable. In the second embodiment of the present invention, the at least one handle assembly  18  further comprises a clamping collar  35 , seen in  FIG. 3 . Moreover, the handlebar  28  further comprises a main tube  32  and an extension tube. The clamping collar  35  connects the main tube  32  with the extension tube  33 . The main tube  32  positions the extension tube  33  with the cylindrical body  2 . Furthermore, the main tube  32  and the extension tube  33  define an overall height for the handlebar  28 . A minimum height of the handlebar  28  is defined by the main tube  32  as the main tube  32  is positioned adjacent with the handlebar receiver  22 . The overall height of the handlebar  28  is extendable with the extension tube  33  as the extension tube  33  is telescopically engaged into the main tube  32 , opposite the handlebar receiver  22 . More specifically, the overall height is defined by both the main tube  32  and the extension tube  33  as the proximal bar end  29  is positioned coincident with the main tube  32 , offset the extension tube  33 , and the distal bar end  30  is positioned coincident with the extension tube  33 , offset from the main tube  32 . In order to secure a desired position of the extension tube  33  within the main tube  32 , the clamping collar  35  is operatively coupled with the extension tube  33 , wherein the clamping collar  35  is used to lock a selected positioned of the extension tube  33  along the main tube  32  and is used to unlock the selected positioned of the extension tube  33  along the main tube  32 . 
     In order for the weight of the present invention to be counterbalanced and easily maneuvered by a user, the second embodiment of the present invention preferably comprises at least one handle assembly  18  that further comprises a forearm brace  36 , an extension post  38 , a post-receiving channel  39 , a main hole  40 , a plurality of secondary holes  41 , and a fastener  42 , also seen in  FIG. 3 . The forearm brace  36  presses against the forearm of the user while the user grasps the handle grip  33 . The extension post  38  offsets the forearm brace  36  with the handle grip  33  and connects the forearm brace  36  with the handle grip  33 . The post-receiving channel  39  provides passage for the extension post  38  through the handle grip  33  while preserving the structural integrity of the handle grip  33 . Similarly, the main hole  40  provides passage of the fastener  42  through the handle grip  33  and the post-receiving channel  39  while preserving the structural integrity of the handle grip  33 . The plurality of secondary holes  41  allows the fastener  42  to traverse through the extension post  38 , and consequently the handle grip  33 , while preserving the structural integrity of the extension post  38 . Furthermore, the plurality of secondary holes  41  allows the distance between the handle grip  33  and the forearm brace  36  to be adjustable. The fastener  42  secures the position of the extension post  38  within the post-receiving channel  39 . In order for the forearm of the user to be readily positioned within the forearm brace  36 , a brace opening  37  of the forearm brace  36  is positioned offset from the extension post  38  and is oriented towards the handlebar  28 . The brace opening  37  provides enough space for the forearm of the user to be positioned within the forearm brace  36  while maintaining the contour of the forearm brace  36  around the forearm of the user. The forearm brace  36  is terminally fixed with the extension post  38  effectively connecting the forearm brace  36  with the handle grip  33  without limiting the range of movement by the corresponding arm of the user. In order for the hand of the user to grasp the handle grip  33  while the forearm is simultaneously positioned within the forearm brace  36 , the post-receiving channel  39  laterally traverses through the handle grip  33  and is positioned offset from the handlebar  28  along the handle grip  33 . Furthermore, the post-receiving channel  39  is oriented at an obtuse angle with the handle grip  33 , thereby preserving the ergonomic structure of the handle grip  33  and the handle grip  33  with the forearm brace  36 . In order to prevent the extension post  38  from slipping entirely through the post-receiving channel  39 , the main hole  40  laterally traverses through the handle grip  33 , and the post-receiving channel  39  is perpendicularly intersected by the main hole  40 . The fastener  42  may continuously traverse through the handle grip  33  and the extension post  38  as each of the plurality of secondary holes  41  laterally traverses through the extension post  38 . The plurality of secondary holes  41  is positioned offset from the forearm brace  36  along the extension post  38 , providing variable distances between the handle grip  33  and the forearm brace  36  for users with various sized arms.

More specifically, any particulates are limited from entering the suction chamber  15  as the first mesh filter  57  is positioned adjacent with the suction chamber  15 . Furthermore, the debris screen  59  is positioned adjacent with the first mesh filter  57 , opposite the debris chamber  14 . In order for the suction fan  52  to remain uninhibited, the housing  53  is positioned adjacent with the debris screen  59 , opposite the first mesh filter  57 . Moreover, the housing  53  is concentrically positioned within the cylindrical body  2 , defining a linear and continuous airflow through the cylindrical body  2 . The second mesh filter  58  is positioned adjacent with the housing  53 , opposite the debris screen  59 , preventing any particulates from escaping past the outlet  4 . The second mesh filter  58 , along with the suction fan  52 , the debris screen  59 , and the first mesh filter  57  are securely housed as the at least one exhaust screen  60  is mounted across the outlet  4 . Any wire connections between the controller unit  67  with the suction fan  52  and the portable power source  50  remain minimal as the controller unit  67  is mounted within the canister  1 , adjacent to the portable power source  50 . In order to generate airflow, the impeller  54  and the motor  55  are positioned within the housing  53 . The impeller  54  preferably is positioned adjacent with the debris screen  59 , and the motor  55  is positioned adjacent with the second mesh filter  58 , thereby maximizing the suction into the cylindrical body  2 . However, it is understood, in alternate embodiments of the present invention, the motor  55  is positioned adjacent with the debris screen  59 , and the impeller  54  is positioned adjacent with the second mesh filter  58 . In order to rotate the impeller  54 , the impeller  54  is torsionally connected with a rotor  56  of the motor  55 . The rotor  56  of the motor  55  rotates the impeller  54 . In order for the motor  55  to be operated, the controller unit  67  is electronically connected with the motor  55 . In order to turn the suction fan  52  on and off, the portable power source  50  is electrically connected to the controller unit  67 , thereby allowing a user to connect and disconnect the flow of power between the portable power source  50  with the suction fan  52 . 
     In the preferred embodiment of the present invention, the at least one exhaust screen  60  comprise a first exhaust screen  61 , seen in  FIG. 2  and  FIG. 5 . Alternate embodiments of the present invention may comprise a variety of exhaust screens that engage with the cylindrical body  2  in various ways and prevent any small items from entering into the suction chamber  15  through the outlet  4 . The first exhaust screen  61  comprises a first screen rim  62  and a perforated plate  63 . The first screen rim  62  connects the first exhaust screen  61  with the cylindrical body  2 . The perforated plate  63  serves as a shield across the first screen rim  62 . In order to enclose the cylindrical body  2 , the first screen rim  62  is perimetrically fixed around the perforated plate  63 , and the perforated plate  63  is positioned across the outlet  4 . The first screen rim  62  is attached onto the cylindrical body  2 , thereby housing  53  second mesh filter  58 , the suction fan  52 , the debris screen  59  and the first mesh filter  57  within the suction chamber  15 . 
     Depending on the number of debris and animal waste that needs to be collected and the size of the area with the debris and waste, the overall weight of the present invention may be taxing for the user. In order to alleviate the weight of the present invention and the collected animal waste, the present invention further preferably comprises a wheel assembly  70 , seen in  FIG. 1 ,  FIG. 2 ,  FIG. 3 , and  FIG. 4 . The wheel assembly  70  allows the canister  1  to be rolled while simultaneously maneuvered with the handle grip  33  or the handle grip  33  and the forearm brace  36 . In order for the canister  1  to be offset from the ground with the wheel assembly  70 , the wheel assembly  70  is laterally mounted with the cylindrical body  2 . Moreover, the wheel assembly  70  is positioned opposite to the at least one handle assembly  18  about the cylindrical body  2  as the ground is positioned opposite of the at least one handle assembly  18 . In order for the airflow inlet nozzle  43  to remain oriented towards the ground and the canister  1  to be effectively supported while rolling across the ground, the wheel assembly  70  is positioned adjacent to the suction chamber  15  and is positioned offset with the outlet  4 .
