1. A scrubbing device including a body portion suitable for movement along a surface to be scrubbed;
- a pair of tank chambers and separator means communicating with each of said chambers, said separator means being capable of separating a dirty scrubbing solution into a clean solution portion and a solid matter portion, said separator means comprising a plurality of laminar flow zones, and said separator means conveying said clean portion into one of said chambers and said solid matter portion into the other of said chambers, said separator means including means for applying a back pressure to said laminar flow zones thereby minimizing short circuiting and non-uniform flow through said laminar flow zones;
applicator means communicating with said one tank chamber and adapted for applying scrubbing solution to a surface to be scrubbed;
means for metering the amount of scrubbing solution applied to said surface;
brush means for agitating said solution on said surface, andpick up means for lifting said scrubbing solution from said surface and depositing said solution in said other tank chamber.

Abstract
A scrubber is disclosed including an applicator for applying a cleaning solution, a rotary brush for working such solution on the soiled surface and a pick up section for removing the cleaning solution and suspended soilage from the surface being scrubbed. The scrubber includes a dirty solution chamber and a clean solution chamber. A separator is provided between such chambers to separate the dirty water into a sludge portion which is returned to the dirty water chamber and a clean solution portion which is fed into the second chamber.

13. A scrubbing device including a body portion suitable for movement along a surface to be scrubbed;
-
a pair of tanks and laminar flow separator means communicating with each of said tanks, said separator means being capable of separating a dirty scrubbing solution into a clean solution portion and a solid matter portion, said separator means including a plurality of laminar flow settling zones, said laminar flow separator means including perforate plate means for assuring uniform rates of flow through each of said laminar flow settling zones, and means for conveying said clean portion into one of said tanks; applicator means communicating with said one tank and adapted for applying scrubbing solution to a surface to be scrubbed; means for agitating said solution on said surface; and pick up means for lifting said scrubbing solution from said surface and depositing said solution into the other of said tanks.

14. A scrubbing device including a body portion suitable for movement along a surface to be scrubbed;
-
a pair of zones suitable for containing scrubbing solution, and laminar flow separator means providing solution communication between said pair of zones, said separator means being capable of separating a dirty scrubbing solution into a clean solution portion and a solid matter portion, said separating means comprising a plurality of laminar flow settling zones, said separator means further including an open celled sponge-like member disposed above said pluraity of laminar flow settling zones to facilitate uniform flow through each of said laminar flow settling zones; applicator means communicating with one of said containing zones and adapted for applying scrubbing solution to a surface to be scrubbed; and pick up means for lifting said scrubbing solution from said surface and depositing said solution in the other of said containing zones. - View Dependent Claims (15, 16)
