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 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 has a base, a wheel, a handle, a motor, and a power source. A low-profile extension arm extends from the base. Ahead is carried by a distal end of the extension arm. A shuttle is carried by and reciprocally positioned in the head. A scrub pad is coupled to the shuttle. The head is pivotally coupled to the distal end of the extension arm and has at least two different rotational orientations with respect to the extension arm to selectively orient the linear axis with respect to the extension arm. A lock selectively locks the head in one of the at least two different rotational orientations.

Disclosed is a cleaning device, including a main body; the main body is provided with a first accommodating chamber and a first electronic assembly and the first electronic assembly is located in the first accommodating chamber; a top of the first accommodating chamber is provided with a first opening, a first flow drainage channel inlet is formed around the top of the first accommodating chamber, the first flow drainage channel inlet is communicated with a first flow drainage channel, an edge of the first opening is provided with a first waterproof stopper, the first flow drainage channel inlet is adjacent to the first waterproof stopper, and the first flow drainage channel discharges liquid around the top of the first accommodating chamber to an outside of the main body through the first flow drainage channel inlet.

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.

An automatic cleaning device, includes: a mobile platform; a circuit board, which is arranged in the mobile platform and comprises a circuit board body provided with a middle area and an edge area surrounding the middle area; interface devices arranged on the circuit board body and located in the edge area; electronic devices arranged on the circuit board body and located in the middle area; and a blocking rib arranged between the interface devices and the electronic devices and configured to block liquid and/or moisture from coming into contact with the electronic devices.
