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.

Abstract: A vacuum cleaner and suction nozzle thereof. The vacuum cleaner has a housing, dust collecting unit, filter assembly, motor assembly and roller brush. The suction nozzle has a bottom housing, front cover and roller brush. The housing includes a concave cavity; the bottom housing and the front cover latch together to form a chamber; the roller brush assembly and the separation piece fit into this chamber; the separation piece corresponds to a transmission component of the roller brush. When rotating at high speed, the roller brush forms a seamless and closed separation face with the separation piece, preventing foreign matter from entering the transmission component, thus avoiding reduced suction and damage due to a tangled synchronous belt or a shaft jamming a roller brush bearing.

Abstract: A vacuum cleaner brushroll clutch having a motor, clutch assembly input rotated by the motor, brushroll, clutch assembly output to rotate the brushroll, drive clutch, and starter clutch. The drive clutch is connected to the clutch assembly output and moveable between a first position in which it does not directly contact the clutch assembly input and a second position in which it directly contacts the clutch assembly input to transmit a first torque directly from the clutch assembly input to the clutch assembly output. The starter clutch is connected to the drive clutch and moveable between a first position in which it does not engage the clutch assembly input and a second position in which it engages the clutch assembly input to transmit a second torque from the clutch assembly input to the drive clutch to move the drive clutch into the second drive clutch position.
