Abstract

A floor cleaning device (10) includes a housing (40) and a container (43) removably received by the housing. A suction nozzle (18, 18′, 18″) is fluidly connected with the container and with a suction source (52) when the container is received by the housing. A filter (114) is selectively fluidly connected with the container and with the suction source. A float (170) selectively closes the fluid connection of the filter with the container. The filter and the float may be removable as a unit (42) from the cleaning device. The nozzle may be removable, allowing an appropriate nozzle to be selected according to the type of floor surface to be cleaned.

Claims

1. A floor cleaning device comprising:

a base portion for movement along a surface;

a handle portion pivotally connected to said base portion;

a nozzle assembly associated with said base portion and movable in relation to said base portion, said nozzle assembly including a nozzle body and a squeegee attached to said nozzle body, said nozzle assembly being removably mounted on said base portion by a connector which connects the nozzle assembly with a conduit that defines a portion of a fluid flowpath;

a brush assembly associated with said base portion, said brush assembly comprising an agitator; and

,

wherein said nozzle assembly is, in a first position raised off the surface for vacuuming the surface, said nozzle assembly being lowered to a second position contacting the surface for picking up liquid and dirt from the surface, and a height of said base portion in relation to the surface remains unchanged in the first and second positions of said nozzle assembly.

2. The floor cleaning device of claim 1 further comprising an actuator operatively connected to said base portion such that said actuator selectively raises said nozzle assembly from said second position, in which it contacts the surface, to said first position.

3. The floor cleaning device of claim 1 further comprising a motor for driving said agitator.

4. The floor cleaning device of claim 3 wherein said agitator comprises a brushroll and further comprising a drive belt drivably connected between said motor and said brushroll.

5. The floor cleaning device of claim 3 further comprising a switch for selectively actuating said motor.

6. The floor cleaning device of claim 1, wherein the nozzle assembly is removably connected with the base solely by the connector.

7. A floor cleaning device comprising:

a base portion for movement along a surface, said base portion including a distributor for distributing cleaning liquid onto the surface;

rotation members connected to said base portion and engaging the surface;

a handle portion pivotally connected to said base portion;

a nozzle assembly associated with said base portion and movable in relation thereto, said nozzle assembly including a nozzle body composed of a relatively rigid material, said nozzle assembly including a squeegee attached to said nozzle body, the nozzle body including a tubular rear end which defines a fluid outlet, the tubular rear end being removably secured to a fluid conduit by a receiving collar;

a brush assembly associated with said base portion, the brush assembly including an agitator;

a motor for driving said agitator; and

an actuator operatively connected to said base portion such that actuating said actuator moves said nozzle assembly in relation to said base portion between a first position raised off of the surface to vacuum the surface, and a second position in which said squeegee engages the surface to collect and pick up liquid and dirt from the surface, wherein a height of said base portion in relation to the surface remains unchanged as said nozzle assembly is moved to said first and second positions.

8. The floor cleaning device of claim 7 wherein said nozzle assembly is removably mounted on said base portion.

9. The floor cleaning device of claim 7 including a retainer mounted to said nozzle body, said squeegee being attached to said retainer.

10. The floor cleaning device of claim 7 wherein said actuator comprises a pedal operatively connected to said base portion such that depressing said pedal moves said nozzle assembly to one of said first position and said second position.

11. The floor cleaning device of claim 7 wherein said rotation members include a pair of wheels rotatably connected on opposite sides of said base.

12. The floor cleaning device of claim 7 further comprising:

a suction source communicating with said nozzle, said suction source being supported by one of said base portion and said handle portion; and

a container supported by one of said base portion and said handle portion for receiving dirt from the surface.

13. The floor cleaning device of claim 7 further comprising a connection assembly for selectively connecting said nozzle to said base member.

14. The floor cleaning device of claim 13 wherein the adjustment mechanism is connected to the connection assembly, whereby when the nozzle is removed, it is disconnected from the actuator.

15. A cleaning device comprising:

a base;

a handle pivotally connected to said base;

a container carried by one of said base and said handle for receiving dirt from a surface to be cleaned;

a reservoir carried by one of said base and said handle for supplying a cleaning solution to the surface to be cleaned;

a source of suction carried by one of said base and said handle and in fluid communication with said container;

an agitator rotatably mounted to said base;

a suction nozzle carried by said base, the suction nozzle including an inlet, forward of said agitator, for receiving dirt from the surface to be cleaned and tubular outlet, rearward of said agitator; and

,

an adjustment mechanism for moving said suction nozzle, relative to said base, between a first position, in which said inlet is located adjacent the surface to be cleaned and a second position, in which said inlet is spaced from the surface, said adjustment mechanism pivoting the suction nozzle at a pivot point connected to the outlet.

16. The cleaning device of claim 15, further including at least one squeegee mounted to said suction nozzle adjacent said inlet, said squeegee contacting the surface to be cleaned when said suction nozzle is in the first position and being spaced from the surface when said suction nozzle is in the second position.

17. The cleaning device of claim 15, wherein said adjustment mechanism includes a pivoting link for pivotally connecting said suction nozzle to said base.

18. The cleaning device of claim 17, wherein said adjustment mechanism further comprises a pedal operatively connected to said pivoting link.

19. The cleaning device of claim 15, further comprising a motor for driving said agitator.

20. The cleaning device of claim 19, wherein said agitator comprises a brushroll and further comprising a drive belt drivably connected between said motor and said brushroll.

21. A cleaning device comprising:

a base;

a handle pivotally connected to said base;

a container carried by one of said base and said handle for receiving dirt from a surface to be cleaned;

a reservoir carried by one of said base and said handle for supplying a cleaning solution to the surface to be cleaned;

a source of suction carried by one of said base and said handle and in fluid communication with said container;

an agitator rotatably mounted to said base;

a suction nozzle removably connected to said base by a connector which connects the suction nozzle with a conduit which defines a fluid flowpath fluidly connecting the suction nozzle with the source of suction, the suction nozzle including an inlet for receiving dirt from the surface to be cleaned and an outlet; and

an adjustment mechanism for moving said suction nozzle, relative to said base, between a first position, in which said inlet is located adjacent the surface to be cleaned and a second position, in which said inlet is spaced from the surface,

the adjustment mechanism being connected with the conduit, wherein disconnecting the nozzle from the connector disconnects the suction nozzle from the adjustment mechanism.
