ABSTRACT:
A heavy-duty floor-cleaning machine for such work as cleaning encrusted diamond-plate catwalks in ship engine rooms comprises a housing on wheels spacing it from the floor with the housing containing a rotating cylindrical wire brush driven by belts by an electric motor mounted rearward thereof inside the housing. The shaft of the wire brush is mounted in manually adjustable supports that permit the wire brush to be lowered with respect to the housing as brush wear occurs. The electric motor also drives air impellers or fans that expel air and debris from the housing into a collecting bag in the manner of a vacuum cleaner.
