A waste collection and disposal system for collecting and disposing of waste material collected through a suction line during a medical procedure, said system comprising: a waste collection unit including: a portable cart; a waste container (200, 202) supported by said portable cart for coupling to the suction line to collect the waste material during the medical procedure; and a first plurality of couplings (1026, 1027) mounted to the cart and being in fluid communication with the waste container (200, 202); a docking station spaced from said waste collection unit for disposing of the waste material collected by said waste collection unit and for cleaning said waste container (200, 202), said docking station including: a cabinet; and a second plurality of couplings (1010, 1011) for mating with the first plurality of couplings (1026, 1027), characterized in that: a carrier is mounted to the portable cart for carrying the first plurality of couplings (1026, 1027); a head extends from the cabinet, the head including: the second plurality of couplings (1010, 1011), a mating interface carrying said second plurality of couplings (1010, 1011) and configured to move said second plurality of couplings (1010, 1011) upwardly to mate the second plurality of couplings (1010, 1011) with the first plurality of couplings (1026, 1027), and a floating frame carrying said mating interface and positioned so that, when the waste collection unit is placed adjacent the cabinet, the waste collection unit carrier engages said floating frame, wherein the engagement of said floating frame by said carrier aligns the second plurality of couplings (1010, 1011) with the first plurality of couplings (1026, 1027) so that the first (1026, 1027) and second (1010, 1011) plurality of couplings mate together to provide fluid communication between the waste collection unit and the docking station for purposes of draining the waste material from the waste collection unit and/or cleaning the waste collection unit. a waste collection unit including: a portable cart;
