The present disclosure relates to an automatic cleaning device and a sweeping assembly thereof. The sweeping assembly includes: a brush holder, a brush body disposed at least partially in the brush holder; and an anti-winding structure. The anti-winding structure is located at a joint of the brush body and the brush holder, where the anti-winding structure is configured to at least partially fill a gap at the joint when the sweeping assembly is in a working state.

A robot cleaner includes a main body, a moving unit for moving the main body, a cleaning module capable of being brought into contact with a floor surface at at least part of a lower surface thereof, and a module drive unit for controlling an angle of inclination of the lower surface of the cleaning module with respect to the floor surface.

Drivable path plan systems and methods for autonomous vehicles disclosed herein may receive original path plan data, including a first path element tangentially connected to a second path element at a transition connection point. A drivable path plan may be calculated for the autonomous vehicle between the first path element and the second path element using a clothoid spline. An initial connection point may be identified, as well as an initial heading and an initial curvature along the first path element, and a final connection point, a final heading, and a final curvature along the second path element. The clothoid spline may be inserted between the initial connection point along the first path element and the final connection point along the second path element.

The present disclosure discloses an automated floor cleaning apparatus, has an automatic cleaning robot and a washing base; the rear end of the robot body of the automatic cleaning robot is provided with a mop mechanism, the mop mechanism comprises a rotation component rotatably connected to the robot body and a crawler-type wiping cloth sleeving outside and rotating along with the rotation component. The invention provides can automatically and effectively removes dirt attached to the crawler-type wiping cloth, avoiding artificial detaching and then cleaning the wiping cloth stained with dirt, automatically performing washing operation, greatly alleviating operation burden of a user, and having a good floor sweeping effect.

A cleaning device includes a host, a drag head assembly and a water spray assembly. The host includes a housing, a control device housed in the housing and a handle member fixedly connected to the housing. The housing contains a water inlet pipe for connecting to a water source. The drag head assembly is fixed on the housing and electrically connected to the control device. The control device is used to control the drag head assembly for cleaning operations. The drag head assembly includes a cleaning brush head. The water spray assembly is fixed in the drag head assembly and connected to the end of the water inlet pipe away from the water source. The water spray assembly has evenly set spray holes. The direction of the spray holes is towards the cleaning brush head.
