SIDE BRUSH AND ROBOTIC CLEANER
First Claim
1. A side brush for a robotic cleaner, the side brush being rotatable about a rotation axis in a rotational direction and comprising:
- a brush body; and
numerous bristles including a first bristle having a base end at the brush body and an opposite distal end;
wherein the numerous bristles extend freely from the brush body to their respective distal ends;
wherein the rotation axis extends centrally through the brush body and an imaginary line extends perpendicularly to the rotation axis;
wherein the first bristle is arranged with its base end at a distance from the rotation axis on the imaginary line and extends extending in a bristle direction outwardly from the brush body;
wherein seen in a top view, along the rotation axis, the bristle direction extends at a first angle (α
) to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction, andwherein seen in a side view, along the imaginary line, the bristle direction extends at a second angle (α
) to the rotation axis pointing away from the brush body.

Abstract
A side brush for a robotic cleaner. The side brush is rotatable about a rotation axis in a rotational direction and has a brush body and numerous linear bristles including a first bristle having a base end at the brush body and an opposite distal end. An imaginary line extends perpendicularly to the rotation axis. The first bristle extends in a bristle direction outwardly from the brush body. Seen in a top view, the bristle direction extends at a first angle to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction. Seen in a side view, the bristle direction extends at a second acute angle to the rotation axis pointing away from the brush body. A robotic cleaner having such a side brush is also disclosed herein.

11. A robotic cleaner comprising:
-
a housing; a drive arrangement being configured to drive the robotic cleaner along a surface to be cleaned; a debris receptacle arranged inside the housing; a nozzle inlet in the housing and facing the surface to be cleaned; and a side brush rotatable about a substantially vertical rotation axis, wherein the side brush comprises; a brush body; and numerous bristles including a first bristle having a base end at the brush body and an opposite distal end; wherein the numerous bristles extend freely from the brush body to their respective distal ends; wherein the rotation axis extends centrally through the brush body and an imaginary line extends perpendicularly to the rotation axis; wherein the first bristle is arranged with its base end at a distance from the rotation axis on the imaginary line, and extends in a bristle direction outwardly from the brush body; wherein seen in a top view, along the rotation axis, the bristle direction extends at a first angle (α
) to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction, andwherein seen in a side view, along the imaginary line, the bristle direction extends at a second angle (α
) to the rotation axis pointing away from the brush body. - View Dependent Claims (12, 13, 14)
