1. A scrubbing device including a body portion suitable for movement along a surface to be scrubbed;
- a tank including a pair of tank chambers and separator means providing communication between said chambers, said separator means comprising a basket-like filter member, said separator means being capable of separating a dirty scrubbing solution into a clean solution portion and a solid matter portion, said clean portion being fed into one of said tank chambers, said basket-like filter member comprising a mesh basket and a box-like filter member being spaced from the bottom of said tank, thereby providing a first tank chamber outside said basket-like filter member and a second tank chamber within said basket-like filter, said tank including means cooperating with said basket-like filter member to prevent downward movement of said basket-like filter member, and to concurrently preclude any resistance against upward movement of said basket-like filter member to thereby allow said basket-like filter member to be readily removable at all times for dumping the used box-like filter.

6. A scrubbing machine adapted for recirculation of scrubbing solution, said machine comprising:
-
a chamber for holding scrubbing solution; means for applying scrubbing solution from said holding chamber to a surface to be scrubbed; vacuum means for lifting said scrubbing solution from said surface; means for separating the lifted solution into a reusable portion and a solid matter portion, said separating means comprising a basket filter unit disposed in said holding chamber, said basket filter unit comprising a wire basket supported in said holding chamber and a basket-like filter supported in said wire basket, said holding chamber including means cooperating with said wire basket to prevent downward movement of said wire basket, and to concurrently preclude any resistance against upward movement of said wire basket to thereby allow said wire basket to be readily removable at all times to dump said filter; and means for conveying said lifted solution into said holding chamber whereby said solution may be separated by said filter unit. - View Dependent Claims (7, 8)
