Abstract

A remote-controlled vacuum cleaner comprises a vacuum cleaner vehicle designed to be positioned and moved in any direction relative to a surface (e.g., a carpet) to be cleaned, and a handheld remote control device including a control element (e.g., a joystick, a roller ball, or the like) and a transmitter for sending control signals to electronic motor drive circuits in the vehicle. According to the invention, the handheld remote control device preferably is controlled by a processor and includes a display (e.g., a video monitor) for displaying images from one or more cameras located on or within the vacuum cleaner vehicle. The vacuum cleaner vehicle preferably includes a misting device in which cleaning solution is stored. The misting device includes a nozzle for misting the cleaning solution onto the surface to be cleaned, preferably prior to the vacuuming operation. The vacuum cleaner vehicle preferably also includes a dryer mechanism (e.g., a blower, an electric resistive heater, or the like) for heating the surface to be vacuumed to enhance the cleaning operation and/or to remove any excess cleaning solution. The vacuum cleaner vehicle may also be foldable to reduce its size for storage.

Claims

1. Apparatus, comprising:

a remote controller; and

a vacuum cleaner vehicle, the vehicle including a misting device for spraying a given fluid on a given first portion of a surface as the vacuum cleaner vehicle is controlled, by the remote controller, to vacuum a given second portion of the surface;

wherein the given first portion of the surface receives an application of the given fluid prior to vacuuming of the given first portion;

wherein the vehicle further includes a drying device for drying the given fluid after the given second portion of the surface has been vacuumed.

2. The apparatus as described in claim 1 wherein the vacuum cleaner vehicle includes at least one sensor for locating an edge of the surface.

3. The apparatus as described in claim 1 wherein the given fluid is a carpet cleaning solution.

4. The apparatus as described in claim 1 wherein the given fluid is an air freshener.

5. The apparatus as described in claim 1 wherein the given fluid is water.

6. The apparatus as described in claim 1 wherein the vehicle includes at least one camera and the remote controller includes a display to display images provided to the remote controller from the camera.

7. Apparatus, comprising:

a remote controller, and

a vacuum cleaner vehicle including;

a misting device for spraying a given fluid on a surface;

a drying device for drying the given fluid; and

a vacuum device for suctioning debris from the surface;

wherein the vehicle is controlled by the remote controller selectively in one of a manual and autonomous mode (a) to move the vehicle along a given path;

(b) to spray the given fluid on the surface using the misting device as the vehicle is in motion;

(c) to suction debris from the surface using the vacuum device as the vehicle is in motion, and (d) to dry the given fluid from the surface using the drying device.

8. The apparalus as described in claim 7 wherein the vacuum cleaner vehicle includes at least one sensor.

9. The apparatus as described in claim 8, wherein the sensor determines if the vehicle is approaching an edge of the surface.
