Abstract

A robotic floor cleaning device that contains a cleaning fluid reservoir to store cleaning fluid and uses ultrasonic oscillators to vaporize the cleaning fluid. Vapor is delivered via nozzles to a work surface to remove debris therefrom.

Claims

1. A robotic floor cleaning device comprising:

a chassis including a set of wheels;

a motor to drive the wheels, the motor electrically coupled to a battery disposed in the chassis;

a control unit to provide at least one movement path to the robotic floor cleaning device;

a fluid reservoir to store a cleaning fluid;

one or more ultrasonic oscillators electrically coupled to the battery to vaporize fluid in the fluid reservoir; and

,

a plurality of nozzle sets dispersed across an underside of the robotic floor cleaning device and a mopping cloth positioned below the plurality of nozzle sets to receive the vaporized fluid across a top surface of the mopping cloth wherein a bottom surface of the mopping cloth wipes the work surface.

2. The robotic floor cleaning device of claim 1 wherein said mopping cloth is removably attached to the chassis.

3. The robotic floor cleaning device of claim 1 wherein said ultrasonic oscillators operate continuously at a constant rate.

4. The robotic floor cleaning device of claim 1 wherein said ultrasonic oscillators turn on at intervals.

5. A robotic floor cleaning device comprising:

a chassis including a set of wheels;

a motor to drive the wheels;

a control unit to provide at least one movement path to the robotic floor cleaning device;

a fluid reservoir to store a cleaning fluid;

one or more ultrasonic oscillators for vaporizing cleaning fluid from the fluid reservoir;

a plurality of nozzle sets dispersed across an underside of the robotic floor cleaning device that direct vaporized fluid to a work surface; and

a mopping cloth positioned under the plurality of nozzle sets to receive the vaporized fluid across a top surface of the mopping cloth wherein a bottom surface of the mopping cloth wipes the work surface.

6. The robotic floor cleaning device of claim 5 wherein said oscillators for vaporizing the cleaning fluid from the fluid reservoir is activated continuously at a constant rate.

7. The robotic floor cleaning device of claim 5 wherein said oscillators for vaporizing the cleaning fluid from the fluid reservoir is activated at predetermined intervals.
