This document describes a mobile cleaning robot that includes a chassis that supports a drive system, a debris collection volume; and a cleaning head formed to complete a bottom of the robot. The cleaning head includes a frame for affixing the cleaning head to the chassis, a monolithic housing having an interior cavity, a suspension linkage movably suspending the monolithic housing from the frame, the suspension linkage being configured to lift the monolithic housing, a diaphragm formed of a flexible material and mated to the monolithic housing, a rigid duct mated the frame to form a pneumatic path between the monolithic housing and the rigid duct through the diaphragm, and cleaning extractors disposed in the interior cavity of the monolithic housing.

The present disclosure relates to a cleaner including a cleaning module which cleans a cleaning area by generating steam. The cleaning module includes: a cleaning module housing which is connected to the main body, forms an appearance, and forms a space therein; a heater which is disposed within the cleaning module housing and generates steam from water; an air inlet which is formed on one side of the cleaning module housing and into which external air is introduced; and an air outlet which is formed on the cleaning module housing, is disposed above the air inlet, and through which the air in an internal space of the cleaning module is discharged to the outside. As a result, electronic equipment disposed around the heater can be prevented from being damaged by the heat emitted from the heater.

A surface cleaner and method of operation are provided wherein the surface cleaner may include a rotatable nozzle assembly with one or more nozzles which may expel water onto a target surface to be cleaned.

A floor cleaning machine that includes a disc broom that is rotatable about a rotation axis. The disc broom has a base body, bristles and a cover element. The base body has a circumferential outer edge. The bristles are attached at one end to the base body and extend away from the base body towards a sweeping plane that is perpendicular to the rotation axis. The cover element has a shell that is made of a flexible material. The shell extends away from the base body and towards the sweeping plane. The shell has an inner side, which faces an interior of the shell, and an outer side that faces an exterior of the shell. The shell envelopes the bristles perpendicularly to the rotation axis such that the bristles are disposed in the interior of the shell. A related disc broom and sweeping device are also provided.

A surface cleaning head may include a fluid distributor configured to distribute a cleaning fluid, an agitator configured to absorb at least a portion of the distributed cleaning fluid and to agitate debris on the surface to be cleaned, a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator, a debris container, and a removable cover. The debris container may include a solid debris chamber and a fluid debris chamber. The removable cover may include a fluid catch plate configured to transfer at least a portion of the cleaning fluid removed from the agitator by the fluid stripper to the fluid debris chamber, the fluid catch plate being configured to selectively transition between an in-use position and a cleaning position when the removable cover is removed from the surface cleaning head.

The present disclosure provides an autonomous mobile device. The autonomous mobile device includes a device main body, provided with a buffer component on a front side of the device main body; a line laser module, arranged on at least one of the device main body and the buffer component and located between the buffer component and the device main body, wherein the line laser module includes a camera device configured to capture an environmental image and a first window is arranged at a position on the buffer component corresponding to the camera device to enable external ambient light to enter the camera device; and an infrared fill-in lamp, arranged on the buffer component

A floor cleaning tool including a housing, a reservoir coupled to the housing and adapted to hold a cleaning solution, and a floor-engaging roller coupled to the housing and rotatable with respect to the housing. The tool also includes a wheel by which the floor cleaning tool moves across a floor surface in a direction of travel at least partially defining a front, rear, and lateral sides of the floor cleaning tool. The tool further includes a squeegee laterally insertable between the roller and the wheel, and a squeegee mount located between the roller and the wheel by which the squeegee is releasably mounted to the floor cleaning tool by first and second laterally opposed protrusions rotatably secured within first and second apertures at opposite ends of the squeegee.

The present disclosure provides a distance measuring device and a sweeping robot. The distance measuring device includes a base, a baffle, a drive assembly, a ranging component, and a driving component. The baffle is arranged over the base, and may prevent foreign matters over the baffle from intruding into the drive assembly. The baffle may be a portion extended upwards from the base, or may be arranged over the base in a mounting manner. The drive assembly may transmit power of the driving component to the ranging component. The driving component and the ranging component are mounted on the base. The baffle is arranged over the base, and defines a closed or a semi-closed mounting chamber with the base to block foreign matters from intruding into the drive assembly.

A floor cleaning machine with a frame, with a running gear which has at least one wheel, wherein the running gear is configured in such a way that the floor cleaning machine can be moved over a floor surface to be cleaned, with at least one cleaning device which is configured to engage with the floor surface to be cleaned, wherein the floor cleaning machine has a front end, wherein the floor cleaning machine is configured to move over the floor surface to be cleaned in a forward direction in a cleaning operation, wherein during a movement in the forward direction the front end points in the forward direction, with a clearing blade arrangement which is mounted in front of the cleaning device when viewed in the forward direction.

A rotary surface cleaning machine for cleaning floors, including both carpeted floors and uncarpeted hard floor surfaces including but not limited to wood, tile, linoleum and natural stone flooring. The rotary surface cleaning machine has a rotary surface cleaning tool mounted on a frame and coupled for high speed rotary motion relative to the frame. The rotary surface cleaning tool has a substantially circular operational surface that performs the cleaning operation. The rotary surface cleaning tool is driven by an on-board power plant to rotate at high speed. The rotary surface cleaning tool is coupled to a supply of pressurized hot liquid solution of cleaning fluid and a powerful vacuum suction source.
