Patent ID: 8381347

Claim:
An attachment for a vacuum cleaner having a hose providing an airstream to remove liquid from a surface, the attachment comprising: a single-part container defining a structure lacking internal baffle components and internal deflector components, the container including: a reservoir to receive the liquid, the reservoir including a bottom side, a top side, a front side, and a first cross sectional area; a suction port adapted to be coupled to the hose, positioned adjacent the top side of reservoir, and having a second cross sectional area; an inlet nozzle having a third cross sectional area, interfacing with and in communication with the reservoir, and including a portion extending generally downward relative to the top side of the reservoir to collect the liquid from the surface, wherein a portion of the inlet nozzle is spaced apart a predetermined distance from the reservoir, wherein the first cross sectional area of the reservoir is larger than the second cross sectional area of the suction port and larger than the third cross sectional area of the inlet nozzle to cause an air flow velocity in the reservoir to be slower than an air flow velocity in the inlet nozzle and an air flow velocity in the suction port.
