Abstract

A horizontally vibrating brush for an automated robotic vacuum to agitate carpet fibers and like materials in a horizontal rather than vertical plane to loosen debris during vacuuming without causing debris to become more deeply embedded.

Claims

1. A method for agitating debris particles from surfaces using an automated robotic vacuum comprising:

applying power to said automated robotic vacuum;

vibrating a horizontal brush attached to said automated robotic vacuum wherein said brush vibrates in a plane horizontal to the plane of said surface powered by an electric motor;

wherein said brush vibrates by a spring connected to an agitating bar assembly connected to said automated robotic vacuum and wherein said agitating bar delivers movement to said brush through rubber mounts to agitate debris on surface and collecting said debris.

2. The method of claim 1, wherein said brush is a main brush of said automated robotic vacuum.

3. The method of claim 1, wherein said brush is a secondary brush provided separately from a main brush of said automated robotic vacuum.

4. The method of claim 1, wherein said brush is retractable such that said brush does not make contact with the surface on which said automated robotic vacuum is working.

5. The method of claim 4, wherein said automated robotic vacuum further includes a floor detection system wherein light is reflected from the floor surface by a light angled downward onto the floor from the underside of the robotic device;

said light is reflected back to a light sensor located on the underside of the robotic vacuum wherein the light received by the sensor is measured and compared to a predetermined threshold light value which designates that the surface is bare floor or a carpet and based on the measured value said brush is either retracted or engaged dependent upon the detected light sensor value.

6. The method of claim 1, wherein the bristles of said brush are arranged linearly.

9. The methods of claims 4 and 5, wherein said brush may be retracted or engaged.

10. The method of claim 1, wherein said brush may be engaged such that said brush makes contact with a surface on which said automated robotic vacuum is working.

7. A horizontally-vibrating agitator for an automated robotic vacuum comprising:

a member projecting from the bottom of the chassis of said automated robotic vacuum into the surface on which said automated robotic vacuum is working;

wherein horizontal vibrations of said member are provided by a vibrating electric motor delivering vibrations to a spring connected to an agitating bar wherein said agitating bar delivers movement to said member through rubber mounts.

8. A horizontally-vibrating agitator for an automated robotic vacuum comprising:

a member projecting from the bottom of the chassis of said automated robotic vacuum into the surface on which said automated robotic vacuum is working;

vibrating said member in a plane horizontal to the plane on which said automated robotic vacuum is working.
