Abstract
A floor cleaner for providing enhanced fluid application, scrubbing, and fluid extraction from floor surfaces. The floor cleaner includes a housing having a top and a bottom, and a front and a rear. A scrubbing system is provided for applying fluid to a floor surface and rubbing the floor surface. The scrubbing system has a lowered position for contacting the floor surface below the housing and a raised position for positioning the scrubbing system out of contact with the floor system. A vacuum system is provided for removing soiled fluid from the floor surface. Optionally included is an auxiliary cleaning assembly for applying and extracting fluids. The auxiliary cleaning assembly comprises a cleaning wand for applying fluid to and rubbing confined areas, and cleaning wand having first and second portions pivotally mounted together such that the second portion may be pivoted between a stored position and a deployed position.

a central core rotatably mounted on the pair of mounting arms, the central core having a rotational axis, the central core having a substantially cylindrical exterior surface, the central core having a central bore along a portion of said rotational axis, a plurality of passages extending from the central bore to the exterior surface for passing fluid from the central bore through the plurality of passages to the exterior surface of the central core;
a scrubbing sleeve removably mounted on the central core, the scrubbing sleeve comprising a tube portion with an inner surface for abutting against the exterior surface of the central core, the tube portion having an outer surface with a plurality of filaments mounted thereon for extending outwardly from the outer surface of the tube portion, the tube portion having a plurality of holes therethrough for permitting fluid to pass through the tube portion to the filaments;
a supply conduit for supplying fluid to the central bore of the central core, the supply conduit being in fluid communication with the cleaning fluid tank and in communication with the central bore of the central core, a portion of the supply conduit extending along one of the mounting arms;
wherein the vacuum system comprises;
the extractor shield being located rearward of the scrubbing system on the housing, the extractor shield, comprising;
the panel extending downwardly and forwardly, the panel being arcuate, the panel having a transverse width, the transverse width tapering smaller from the lower edge toward the housing, the panel having a thickness, the thickness of the panel tapering thinner from the housing toward the lower edge;
one of the ports being mounted toward each of the lateral edges of the panel, one of the ports being mounted substantially centrally between the lateral edges of the panel;
a screen mounted over each of the suction ports for blocking relatively large debris from entering the ports;
a plurality of suction conduits, each of the suction conduits extending between and in fluid communication with one of the suction ports and the recovery tank;
a suction pump in fluid communication with the suction conduits for pulling fluid through the suction conduits from the ports and moving the fluid to the recovery tank;
floor engaging means for supporting the housing on a floor surface, the floor engaging means being rotatable for facilitating movement of the housing across the floor surface, the floor engaging means being adapted to support the housing a predetermined distance from the floor surface, the floor engaging means being located between the scrubbing system and the vacuum system, the floor engaging means comprising a spherical ball rotatably mounted on the bottom of the housing; and
an auxiliary cleaning assembly for applying and extracting fluids, the auxiliary cleaning assembly being connected to the scrubbing system and the vacuum system, the auxiliary cleaning assembly comprising;
a cleaning wand for applying fluid to and rubbing confined areas, the cleaning wand having first and second portions pivotally mounted together such that the second portion may be pivoted between a stored position and a deployed position, the stored position being characterized by the second portion being rotated into a location adjacent to the first portion, the deployed position being characterized by the second portion being rotated away from the first portion and generally extending away from the first portion, the first and second portions being joined at a pivot joint, the second portion having a central core and a scrubbing sleeve removably mounted on the central core, the scrubbing sleeve having a plurality of filaments mounted thereon, a supply conduit for supplying fluid to the central core from the cleaning fluid tank;
an extractor tube for removing soiled fluid from confined areas, the extractor tube being mounted on the first portion of the cleaning wand, the extractor tube having a section selectively extendable beyond the pivot joint of the cleaning wand the section being selectively retractable so as not to extend beyond the pivot joint, the extractor tube having an open end into an interior of the extractor tube, the interior of the extractor tube being in communication with a suction pump of the vacuum system for permitting fluid to be suctioned through the open end of the extractor tube and pumped into the recovery tank, a conduit fluidly connecting the interior of the extractor tube to the suction pump.
