Abstract

A cleaning device comprises an upper cleaning solution tank comprising an outlet, a motorized chassis located beneath the solution tank and an electronics compartment defined at least partly by splash shields and a drip shield. The splash shields define a top and sides of the electronics compartment, and the drip shield defines a bottom side of the electronics compartment and includes at least one drip hole smaller than 2 mm in diameter. A wire opening in the splash shields includes a protective cover overlying the opening, the protective covering containing at least one passage facing in a direction opposite to the solution tank allowing a wire to pass through the passage, through the wire opening, and into the electronics compartment. Fluid lines extend from the outlet towards a bottom of the cleaning device and exterior to the electronics compartment. An enclosed electronics unit may also include wire openings and protective covers.

First claim

What is claimed is:

1. A cleaning device for cleaning floors comprising:
a solution tank configured to store cleaning solution, wherein the solution tank is located at a top side of the cleaning device and comprises an outlet;
a motorized chassis located beneath the solution tank and comprising an electronics compartment, the electronics compartment defined at least partly by splash shields and a drip shield, the splash shields defining a top and sides of the electronics compartment, and the drip shield defining a bottom side of the electronics compartment;
at least one wire opening in one of the splash shields;
a protective cover overlying the at least one wire opening, the protective cover containing at least one passage facing in a direction opposite to the solution tank and adapted to allow a wire to pass through the passage and through the wire opening into the electronics compartment; and
fluid lines extending from the outlet towards a bottom of the cleaning device and exterior to the electronics compartment.

2. The cleaning device of claim 1 , wherein the electronics compartment is situated laterally to a first side of the cleaning device and the fluid lines extend downward laterally to a second side laterally opposite the first side.

3. The cleaning device of claim 2 , wherein the outlet and the fluid lines are disposed entirely at the second side of the cleaning device.

4. The cleaning device of claim 1 , wherein the at least one passage of the protective cover faces downward.

5. The cleaning device of claim 1 , wherein the drip shield comprises at least one drip hole.

6. The cleaning device of claim 5 , wherein the drip hole is smaller than 2 mm in diameter.

7. The cleaning device of claim 1 , wherein the motorized chassis comprises at least one of a motor for vacuuming the floor or a cleaning component for cleaning the floor.

8. An autonomous floor cleaning machine comprising:
an enclosed electronics unit comprising at least one of electrical, sensor, and communications components and associated wiring entering into and exiting from the electronics unit through at least one first wire opening;
a dry compartment comprising splash shields defining a top and sides of the dry compartment, the dry compartment further comprising at least one additional electrical component and associated wiring entering into and exiting from the dry compartment through at least one second wire opening in one of the splash shields;
a cleaning solution tank located at a top side of the cleaning machine and at least partially disposed above the electronics unit and the dry compartment;
a protective cover overlying the at least one first and second wire openings, the protective cover containing at least one passage facing downward in a direction opposite to the cleaning solution tank and sized to allow the associated wiring to pass through the passage and through the wire openings; and
a wet compartment disposed outside of the dry compartment and comprising fluid lines extending from the cleaning solution tank towards a bottom of the floor cleaning machine.

9. The cleaning machine of claim 8 further comprising a motorized chassis comprising at least one of a motor for vacuuming the floor or a cleaning component for cleaning the floor.

10. The cleaning machine of claim 8 , wherein the dry compartment and the wet compartment are laterally disposed with respect to each other.

11. The cleaning machine of claim 8 , wherein the dry compartment further comprises a drip shield defining a bottom side of the dry compartment, the drip shield comprising at least one drip opening.

12. The cleaning machine of claim 11 , wherein the at least one drip opening is smaller than 2 mm in width.

13. The cleaning machine of claim 8 further comprising a motorized chassis with a plurality of wheels for maneuvering across the floor, each wheel comprising a protective wheel cover that covers portions of the wheel that are at a height greater than or equal to 35 mm.

14. The cleaning machine of claim 8 further comprising a squeegee that is mounted to the cleaning machine in a movable configuration, the squeegee comprising inner and outer deflection wheel mounts, a small deflection wheel adapted for installation to the outer deflection wheel mount and a large deflection wheel adapted for installation to the inner deflection wheel mount, a distance between the inner and outer deflection wheel mounts being proportional to a difference in size between the small and large deflection wheels.

15. The cleaning machine of claim 8 wherein the first wire opening is spaced above a bottom of the enclosed electronics unit.
