Cleaning equipment includesa water divider structure comprisinga pressuresource connected to a water supply tank, a water divider provided with a first distribution channel and a second distribution channel, wherein the first and second distribution channels both are connected with the pressuresource, anda first unidirectional valve connecting between the pressuresource and the water divider, wherein the first unidirectional valve connects through the pressuresource and the water divider under pressure formed when the pressuresource is activated. When there is residual water in the pipeline between the first unidirectional valve and the water divider structure, the first unidirectionalvalve can prevent the water in the water supply tank from being transported downstream. At this time, there is water in the pipeline downstream of the first unidirectionalvalve. One end is closed, and one end of the water divider structure is connected to the outside.

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.

A vacuum cleaner including an airflow passage that extends from a suction inlet to an air outlet, a dirt separator, a suction source operable to generate a suction airflow that travels through the suction inlet, through the dirt separator, and through the air outlet. The vacuum further includes a battery that supplies power to the suction source to generate the suction airflow and a portion of the airflow passage is defined by the battery.

A brushroll for a surface cleaning apparatus includes a brush dowel defining a central rotational axis which extends longitudinally through the brush dowel. The brush dowel includes bristle supports, sweeper supports, and a shroud surface extending between the bristle supports and the sweeper supports. A plurality of bristles protrude from the bristle supports.

A method for controlling one or more operations of an autonomous mobile robot maneuverable within a home includes establishing wireless communication between an autonomous mobile robot and a remote computing system and, in response to receiving a wireless command signal from the remote computing system, initiating one or more operations of the autonomous mobile robot. The autonomous mobile robot is remote from an audio media device stationed within the home. The audio media device is capable of receiving and emitting audio. The remote computing system is configured to associate identification data of the autonomous mobile robot with identification data of the audio media device. The wireless command signal corresponds to an audible user command received by the audio media device.

A cleaning system including a motor, a battery receptacle, and a motor controller. The battery receptacle is configured to receive a battery pack. The battery pack includes one or more battery cells and a battery controller. The motor controller is configured to receive from the battery controller at least one selected from the group consisting of a first signal indicative of a first characteristic of the battery pack and a second signal indicative of a second characteristic of the battery pack. The motor controller is further configured to operate the motor at a defined speed, the defined speed being a first speed upon receiving the first signal and a second speed upon receiving the second signal. Wherein the first characteristic and the second characteristic are at least one selected from the group consisting of a capacity, a current, and a resistance.

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.

A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

A cleaning accessory for a vacuum cleaner comprises a housing. A rotatable cleaning brush is rotatably mounted to the housing. The rotatable cleaning brush has at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is configured to rotate and engage with a surface to be cleaned. A rotatable cleaning bar rotatably is mounted within the housing and the rotatable cleaning brush is rotatably coupled to the rotatable cleaning bar. At least a portion of the rotatable cleaning brush is seated within the rotatable cleaning bar or a drive mechanism coupled to the rotatable cleaning bar.

A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.
