Abstract

A floor cleaning device includes a floor cleaning member, such as a manual wand, having a cleaning solution emitter that emits cleaning solution onto a floor surface. A vacuum generator creates a vacuum so that debris and dirty cleaning solution is suctioned by the floor cleaning member. A filter assembly filters exhaust air of the vacuum generator.

Claims (47)

1 . A floor cleaning device, comprising:

a floor cleaning member having a cleaning solution emitter for emitting cleaning solution onto a floor and an inlet through which debris and dirty cleaning solution is suctioned;

a cleaning solution tank fluidly coupled to the cleaning solution emitter of the floor cleaning member;

a fluid debris tank fluidly coupled to the inlet of the floor cleaning member for receiving debris and dirty cleaning solution therein;

a vacuum generator that creates a vacuum in the fluid debris tank; and

a filter assembly, including an air filter that filters object of a micron or larger in size, disposed between the fluid debris tank and an exhaust air outlet, that filters exhaust air of the of the fluid debris tank;

wherein the filter assembly includes an enclosed box having an inlet in fluid communication with the fluid debris tank and an outlet in fluid communication with or defining the exhaust air outlet:

wherein the filter is disposed within the box intermediate the inlet and outlet thereof, and pressed against a sealing plate disposed between the filter and the box to form an airtight seal between the filter and the sealing plate.

2 . The floor cleaning device of claim 1 , wherein the floor cleaning member comprises a manually operated wand.

3 . The floor cleaning device of claim 2 , wherein a cleaning solution hose extends from the cleaning solution tank to the cleaning solution emitter of the wand.

4 . The floor cleaning device of claim 2 , including a vacuum hose extending from the fluid debris tank to the wand.

5 . The floor cleaning device of claim 1 , including a pump that pumps cleaning solution from the cleaning solution tank to the cleaning solution emitter of the floor cleaning member.

6 . The floor cleaning device of claim 1 , including a wheeled base enabling manual movement of the floor cleaning device from one floor area to another.

7 . The floor cleaning device of claim 1 , wherein the filter removes at least 99% of particles 0.3 microns or greater in size.

8 . The floor cleaning device of claim 1 , wherein the box includes a lid and a base with a gasket therebetween to create an airtight seal.

9 . The floor cleaning device of claim 8 , including a connector that compresses the gasket as the lid is connected to the base.

10 . The floor cleaning device of claim 9 , wherein the connector comprises resilient straps extending between the lid and the base to form an airtight seal therebetween.

11 . The floor cleaning device of claim 1 , including at least one retainer plate disposed between the lid and the filter that presses the filter against the sealing plate.

12 . A floor cleaning device, comprising:

a floor cleaning member comprising a manually operated wand having a cleaning solution emitter for emitting cleaning solution onto a floor and an inlet through which debris and dirty cleaning solution is suctioned;

a cleaning solution tank fluidly coupled to the cleaning solution emitter of the floor cleaning member;

a cleaning solution hose extends from the cleaning solution tank to the cleaning solution emitter of the wand;

a pump that pumps cleaning solution from the cleaning solution tank to the cleaning solution emitter of the floor cleaning member;

a fluid debris tank fluidly coupled to the inlet of the floor cleaning member for receiving debris and dirty cleaning solution therein;

a vacuum hose extending from the fluid debris tank to the wand;

a vacuum generator that creates a vacuum in the fluid debris tank; and

a filter assembly, including an enclosed box having an inlet in fluid communication with the fluid debris tank and an outlet in fluid communication with or defining an exhaust air outlet, and an air filter disposed in the box intermediate the inlet and outlet that filters objects a micron or larger in size from the exhaust air of the fluid debris tank;

wherein the filter is disposed within the box intermediate the inlet and outlet thereof, and pressed against a sealing plate disposed between the filter and the box to form an airtight seal between the filter and the sealing plate.

13 . The floor cleaning device of claim 12 , including a wheeled base enabling manual movement of the floor cleaning device from one floor area to another.

14 . The floor cleaning device of claim 12 , wherein the filter removes at least 99% of particles 0.3 microns or greater in size.

15 . The floor cleaning device of claim 12 , wherein the box includes a lid and a base with a gasket therebetween to create an airtight seal.

16 . The floor cleaning device of claim 15 , including connectors extending between the lid and the base that compressively hold the lid onto the base.

17 . The floor cleaning device of claim 16 , wherein the connectors comprise resilient straps.

18 . The floor cleaning device of claim 15 , including at least one retainer plate disposed between the lid and the filter that presses the filter against the sealing plate.

19 . A floor cleaning device, comprising:

a floor cleaning member comprising a manually operated wand having a cleaning solution emitter for emitting cleaning solution onto a floor and an inlet through which debris and dirty cleaning solution is suctioned;

a cleaning solution tank fluidly coupled to the cleaning solution emitter of the floor cleaning member;

a cleaning solution hose extends from the cleaning solution tank to the cleaning solution emitter of the wand;

a pump that pumps cleaning solution from the cleaning solution tank to the cleaning solution emitter of the floor cleaning member;

a fluid debris tank fluidly coupled to the inlet of the floor cleaning member for receiving debris and dirty cleaning solution therein;

a vacuum hose extending from the fluid debris tank to the wand;

a vacuum generator that creates a vacuum in the fluid debris tank; and

a filter assembly, including an enclosed box having an inlet in fluid communication with the fluid debris tank and an outlet in fluid communication with or defining an exhaust air outlet, and an air filter disposed in the box intermediate the inlet and outlet that filters at least 99% of objects 0.3 microns or larger in size from the exhaust air of the fluid debris tank;

wherein the box includes a lid and a base with a gasket therebetween and connectors that compress the gasket as the lid is connected to the base to form an airtight seal therebetween;

wherein the filter is disposed within the box intermediate the inlet and outlet thereof in contact with a sealing plate; and

wherein at least one retainer plate disposed between the lid and the filter presses the filter against the sealing plate to form an airtight seal between the filter and the sealing plate as the lid is attached to the base.

20 . The floor cleaning device of claim 19 , wherein the connectors comprise resilient straps.
