Abstract
A compact machine for cleaning floors includes a solution tank and dispensing system for dispensing solution onto the surface to be cleaned, a deck assembly for guiding dirty solution to a recovery pickup point, a mechanically operated pump for collecting the dirty solution from the recovery pickup point, and a recovery tank for receiving the collected fluid.
Claims18
A portable, human-powered floor cleaning device comprising:
- a chassis comprising a clean fluid storage tank and a spent fluid collection tank;
- a plurality of wheels for supporting and moving the device;
- a deck assembly comprising a fluid pick-up orifice and a squeegee;
- a mechanically-driven pump housed within the chassis having an inlet and an outlet, the pump operably interconnected to a drive wheel;
- the drive wheel provided substantially proximal to a midpoint of the chassis and comprising an eccentric wheel hub interconnected to a drive shaft such that a rotational movement of the drive wheel results in a reciprocating movement of the shaft and actuation of the pump;
- the fluid pick-up orifice being interconnected to the pump by a conduit for transmitting a spent fluid from the fluid pick-up orifice to the pump;
- a mop comprising a handle;
- and
- at least one attachment member, the at least one attachment member secured at a first end to the chassis, and at a second end attachable to the mop, securing the mop to the device, wherein the mop can be detached from the at least one attachment member to clean portions of the floor not reachable by the device.

A motorless floor washing machine comprising:
- a chassis comprising a clean fluid storage tank and a spent fluid collection tank;
- at least two wheels for supporting and moving the machine;
- a trailing deck assembly comprising a fluid pick-up orifice and a squeegee;
- a mechanically-driven pump housed within the chassis having an inlet and an outlet, the pump operably interconnected to a drive wheel, the drive wheel provided substantially proximal to a midpoint of the chassis and comprising an eccentric wheel hub interconnected to a drive shaft such that a rotational movement of the drive wheel results in a reciprocating movement of the shaft and provides power to the pump;
- the fluid pick-up orifice being interconnected to the pump by a conduit for transmitting fluid from the fluid pick-up orifice to the pump;
- a mop comprising a handle;
- and
- at least one attachment member, the at least one attachment member secured at a first end to the chassis, and at a second end attachable to the mop, securing the mop to the machine, wherein the mop can be detached from the at least one attachment member to clean portions of the floor not reachable by the machine.
5 more elements
A floor cleaning tool for cleaning a surface, comprising:
- a chassis comprising:
- a first tank for containing a cleaning solution, the first tank having a discharge port positioned to effect dispensing of the cleaning liquid therefrom;
- a second tank for receiving the cleaning solution following its being dispensed to the surface;
- and
- a mechanically-driven pump for removing the cleaning solution from the surface and discharging the collected cleaning solution into the second tank;
- a rotatable trailing deck assembly comprising a squeegee, the deck assembly being selectively detachable from the chassis;
- a main wheel assembly comprising at least two wheels for supporting and moving the chassis;
- at least one of the wheels comprising a drive wheel with a rotational motion mechanism for converting the rotational motion of the drive wheel into reciprocal motion;
- the drive wheel provided substantially directly beneath the pump and operably connected to the pump by a drive shaft;
- a mop comprising a handle;
- and
- at least one attachment member, the at least one attachment member secured at a first end to the chassis, and at a second end attachable to the mop, securing the mop to the tool, wherein the mop can be detached from the at least one attachment member to clean portions of the floor not reachable by the tool.
