Abstract

A cleaning device for an autonomous floor treatment appliance, the cleaning device being suitable for cleaning wall portions that are close to a floor and border a floor surface to be cleaned, includes a fixing element to connect the cleaning device to a housing portion of the autonomous floor treatment appliance and a cleaning element carrier having a cleaning element, the cleaning element carrier being connected to the fixing element.

Claims

1. A cleaning device for an autonomous floor treatment appliance, the cleaning device being suitable for cleaning wall portions that border a floor surface to be cleaned, the cleaning device comprising:

a fixing element configured to connect the cleaning device to a housing portion of the autonomous floor treatment appliance;

a cleaning element carrier having a cleaning element, the cleaning element carrier being connected to the fixing element, and the cleaning element being configured to clean wall portions above the floor surface when the fixing element connects the cleaning device to the housing portion and the autonomous floor treatment appliance moves along the floor surface to treat the floor surface; and

a pivoting element pivotably connected to the fixing element, the pivoting element being pivotable about a pivot axis that is oriented substantially parallel to the floor surface when the fixing element connects the cleaning device to the housing portion and the autonomous floor treatment appliance moves along the floor surface to treat the floor surface.

2. The cleaning device of claim 1, wherein the cleaning element carrier is detachably connectable to the pivoting element.

3. The cleaning device of claim 1, wherein the pivoting element has a spring element configured to exert a spring force on the pivoting element, the spring force counteracting pivoting movement of the pivoting element.

4. The cleaning device of claim 1, wherein the cleaning element comprises textile elements.

5. The cleaning device of claim 1, wherein the cleaning element comprises brush elements.

6. The cleaning device as recited in claim 3, wherein the spring element comprises a spiral spring.

7. An autonomous floor treatment appliance having the cleaning device according to claim 1, wherein the cleaning device is substantially attached to the housing portion of the autonomous floor treatment appliance, and the housing portion is oriented substantially vertically to the floor surface to be cleaned.

8. An autonomous floor treatment appliance having the cleaning device according to claim 1, wherein an angle is defined between the pivoting element and a straight line approximately vertical to the floor surface to be cleaned, the angle having a magnitude of between 10 and 90 degrees.

9. The autonomous floor treatment appliance of claim 8, wherein the angle has a magnitude of between 25 and 80 degrees.

10. An autonomous floor treatment appliance having a cleaning device according to claim 1, wherein the cleaning element carrier of the cleaning device extends upwardly beyond a housing of the autonomous floor treatment appliance.

11. An autonomous floor treatment appliance having the cleaning device according to claim 1, wherein the cleaning device is attached to a housing portion of the autonomous floor treatment appliance that is oriented substantially perpendicularly to a main direction of travel of the autonomous floor treatment appliance.

12. A method for controlling an autonomous floor treatment appliance having the cleaning device according to claim 1, the method comprising:

detecting edge regions of the floor surface to be cleaned;

traveling along the edge regions of the floor surface to be cleaned, with the cleaning element of the cleaning device being in contact with wall portions above the floor surface to be cleaned; and

traveling again along the edge regions of the floor surface to be cleaned.

13. The method for controlling an autonomous floor treatment appliance of claim 12, wherein the wall portions close to the floor comprise wall bases or baseboards.
