ROBOTIC VACUUM CLEANER WITH SIDE BRUSH MOVING IN SPIRAL PATTERN

摘要

A robotic cleaning device having a main body , an opening in a bottom side of the main body for removing debris from an area to be cleaned, a brush adjacent to the opening and a propulsion system configured to move the robotic cleaning device across the area. The robotic cleaning device may further include a positioning system having an obstacle detecting device configured to detect obstacles and a processing unit. The obstacle detecting device is configured to record positional data, and the processing unit is configured to generate a cleaning pattern from the positional data, the cleaning pattern including at least one spiral pattern having an outer periphery. The spiral pattern is arranged so that the robotic cleaning device spirals inwards from the outer periphery towards a centre of the spiral pattern, and the brush faces the outer periphery while the robotic cleaning device follows the spiral pattern.

1. A robotic cleaning device comprising:
a main body; an opening arranged in a bottom side of the main body for removing debris from an area to be cleaned; a brush arranged adjacent to the opening; a propulsion system configured to move the robotic cleaning device across the area; and a positioning system comprising an obstacle detecting device configured to detect obstacles and a processing unit, the obstacle detecting device being configured to record positional data; wherein the processing unit is configured to generate a cleaning pattern from the positional data, the cleaning pattern comprising at least one spiral pattern having an outer periphery, the spiral pattern being arranged so that, during the cleaning, the robotic cleaning device spirals itself inwards from the outer periphery towards a centre of the spiral pattern, whereby the brush is arranged to face the outer periphery, while the robotic cleaning device follows the spiral pattern.
