Apparatus for wet cleaning a floor or wall surface
First Claim
1. An apparatus for wet cleaning a floor surface, said apparatus comprising a liquid collecting member defining a movable endless liquid collecting surface thereon, motordriven rotatable brushing means for contacting said floor or wall surface so as to throw dirty washing liquid therefrom on to said liquid collecting surface, a liquid container for collecting dirty washing liquid therein, and transfer means for transferring liquid from the collecting surface to the container, said transfer means including a suction nozzle communicating with the liquid container and being arranged immediately adjacent to the liquid collecting surface so as to suck liquid therefrom.

Abstract
An apparatus for wet cleaning floor or wall surfaces comprises one or more cylindrical brushes which may be rotated by a motor so that they are throwing liquid and dirt from the floor or wall surface on to a rotating cylinder or a moving endless belt. Liquid and dirt is continuously removed from the outer peripheral surface of the cylinder or belt by means of a suction nozzle extending along the axial length of the cylinder and immediately adjacent to the peripheral surface thereof. The suction nozzle may have a lower edge functioning as a scraping member which is in contact with the peripheral surface of a cylinder. Liquid and dirt removed from the cylinder by means of the suction nozzle is passed to a container for collecting dirty liquid.
