Roller mop with wet roller, squeegee, and debris pickup
First Claim
1. A roller mop apparatus for cleaning floors and removing particles of debris therefrom comprising:
- a support structure including a housing having a front wall, a rear wall, opposed side walls and a bottom end;
support wheel means rotatably mounted on said support structure for supporting and moving said structure in a forward and rearward direction on a floor surface to be cleaned;
handle means pivotally connected with said support structure for moving said structure relative to said floor surface, said handle means connected to pivot relative to said support structure and having an upper end extending outwardly from said support structure and a lower end disposed within said support structure;
a generally cylindrical cleaning roller rotatably mounted on said support structure on a transverse axis and having an outer circumference formed of water flexible water absorbing material of sufficient diameter to engage said floor surface;
linkage means connected with said handle means lower end to move in a forward or rearward direction relative to said support structure when said handle means is pivoted;
rotary drive transfer means connected with said linkage means to engage said support wheel means when said linkage means is moved in a forward direction and to become disengaged therefrom when said linkage means is moved in a rearward direction;
said rotary drive transfer means releasably connected with said cleaning roller to transfer rotary motion from said support wheel means to said roller when engaged with said support wheel means, and to become disconnected from said roller when disengaged from said support wheel means.

Abstract
A cleaning mop has a cylindrical roller formed of adjacent disk-shaped rings of resilient foam material which engages and rotates relative to a floor surface to be cleaned to scrub the surface when the mop is pushed in a forward direction and picks up particles of debris when the mop is moved in either direction. When the mop is pushed in a forward direction; the roller is engaged by a drive mechanism to rotate; a valve opens and cleaning liquid flows onto the roller from an onboard reservoir and a gap is formed between the rings by separator fingers as they approach the floor surface; the roller rings engage and move relative to the floor surface and the gap closes to capture particles of debris between the rings; and the dirty liquid and particles carried around the circumferential path on the roller are removed by a squeegee plate and collected in an onboard collection tank. When the mop is pulled in the rearward direction, the roller is disengaged from the drive mechanism to rotate freely and the valve closes to shut off the supply of cleaning liquid. As the disengaged roller rolls on the floor surface the separator fingers widen the gap between the rings and as they approach and engage the floor surface the gap closes to capture particles of debris between the rings; and the particles carried around the circumferential path on the roller are removed by the squeegee plate and collected in the onboard collection tank.
