A scrubbing machine is described which may be operated either in a single cycle scrubbing mode or in a recirculating scrubbing mode. The scrubbing machine includes a body structure which is supported on a plurality of wheels. The scrubber has a pair of tanks one of which is a collector tank and the other of which is a solution feeding tank. A conduit and a pump are provided for moving the solution from the collector tank to the feeding tank. The collector tank may include a filter structure including a flexible conduit and a filtering element.

A scrubbing machine comprising: body means supported on a plurality of wheels; power means for rotatably driving at least one of said wheels; a pair of tanks adapted to contain scrubbing solution; means associated with one of said tanks for applying scrubbing solution from said one tank to a surface to be scrubbed; means for working said solution on said surface; means associated with the other of said tanks for picking up said solution from said surface to said other tank, said pick up means including a vacuum squeegee and pump means for lifting said solution from said squeegee to said other tank; selective means, said selective means being adapted to selectively retain said solution in said other tank during scrubbing thereby providing single cycle scrubbing, said selective means being adapted to selectively pump said solution from said other tank to said one tank thereby providing recycle scrubbing, said selective means further being adapted to selectively pump said solution from said other tank to a discharge thereby providing rapid discharge of used scrubbing solution.
