When the roller brush main body rotates, the dirt can enter the flow guide groove and turn under an action of the flow guide groove.

Provided is a robot including: a chassis; wheels; electric motors; a network card; sensors; a processor; and a tangible, non-transitory, machine readable medium storing instructions that when executed by the processor effectuates operations including: capturing, with at least one exteroceptive sensor, a first image and a second image; determining, with the processor, an overlapping area of the first image and the second image by comparing the raw pixel intensity values of the first image to the raw pixel intensity values of the second image; combining, with the processor, the first image and the second image at the overlapping area to generate a digital spatial representation of the environment; and estimating, with the processor using a statistical ensemble of simulated positions of the robot, a corrected position of the robot to replace a last known position of the robot within the digital spatial representation of the environment.

A kit and method of cleaning a barbeque grill that includes engaging a heat-resistant cloth about a support member of a grill brush; absorbing a quantity of liquid with the heat-resistant cloth; placing the brush with heat-resistant cloth engaged onto previously-heated grill bars of the barbeque grill; generating steam as the quantity of liquid is heated by the grill bars; moving the brush with heat-resistant cloth thereon back and forth along the grill bars; removing food matter and grease from the grill bars; and transferring the removed food matter and grease to the heat-resistant cloth. The removal of food matter and grease is accomplished by a combination of the generated steam and the moving of the brush with heat-resistant cloth thereon back and forth along the grill bars. After use, the heat-resistant cloth is disengaged from the brush and may be washed and reused one or more times.

A rolling brush assembly includes a rolling brush having a rolling brush roller, at least two brush bars, and a protruding strip extending lengthwise along an axis. Each brush bar extends lengthwise in a longitudinal direction of the rolling brush roller. The brush bars are arranged at intervals along a circumferential direction of the rolling brush roller with the protruding strip located between adjacent two brush bars. The at least two brush bars are fixed on the rolling brush roller in one of a flocking or an inserting manner. An engagement portion is formed between the brush bars and the rolling brush roller. A distance from an outer end of the engagement portion to the axis is less than a distance from an outer end of the protruding strip to the axis.

A floor cleaning machine having a cleaning element arrangement with inner and outer cleaning elements that include inner and outer cleaning bodies, respectively, that extend jointly in the cleaning body plane and have first and second receiving openings, respectively. The inner and outer cleaning elements extend from the inner and outer cleaning bodies, respectively, away from the cleaning body plane to one side thereof. The inner cleaning body is arranged in the second receiving opening. The output shaft extends with an output shaft section into both the first and second receiving openings. First and second eccentric elements are attached to the output shaft section and to the inner and outer cleaning bodies, respectively, so that when the output shaft is rotated, the inner and outer cleaning bodies perform eccentric movements that are phase-shifted with respect to one another.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a main housing and a driver. The driver includes a motor and a transmission. The motor is provided behind a rotating brush. The transmission transfers rotational motion of the motor to the rotating brush.

A cleaner head for a vacuum cleaning appliance, the cleaner head including a main body supporting an agitator. The agitator includes a rotatable cylindrical body that bears an elongate agitator formation for engaging a floor surface as the cylindrical body rotates. The elongate agitator formation includes a first agitator row extending around the cylindrical body from a respective first edge L of the cylindrical body towards its centre C in a first helical direction and a second agitator row extending around the cylindrical body from a respective second edge R of the cylindrical body towards its centre C in a second helical direction that is counter to the first helical direction, wherein the first agitator row includes agitators of a first material and wherein the second agitator row includes agitators of a second material that is different to the first material.

An autonomous cleaning robot includes a drive system to move the autonomous cleaning robot about a floor surface, a cleaning head on a bottom portion of the autonomous cleaning robot, a side brush on the bottom portion of the autonomous cleaning robot, and a vacuum system in pneumatic communication with the opening. The cleaning head is configured to direct debris from the floor surface into the autonomous cleaning robot as the autonomous cleaning robot moves about the floor surface. The side brush is rotatable about a rotational axis forming a non-zero angle with a floor surface, and the side brush comprising an opening.

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.
