A cleaning robot is disclosed, the cleaning robot includes a robot body provided with a sweeping rotation element and a mopping rotation element at different positions at a bottom thereof; a drive device provided on the robot body and configured for driving the sweeping rotation element and the mopping rotation element to rotate; wherein the sweeping rotation element is provided to be detachably connected with the sweeping module, and the sweeping module is configured for sweeping a floor; the mopping rotation element is provided to be detachably connected with the mopping module, and the mopping module is configured for mopping the floor. In this way, the cleaning robot has various functions and better cleaning effects.

A cleaning robot according to an embodiment of the present invention comprises: a traveling motor configured to generate a driving force for traveling; a cleaning module changing unit configured to selectively activate any one of at least one cleaning module; a sensing unit configured to sense characteristics of a floor surface; and a processor configured to perform a cleaning operation of cleaning the floor surface by controlling the cleaning module changing unit to activate any one of the at least one cleaning module based on the sensed characteristics of the floor surface, wherein the processor is configured to: sense characteristics of a contaminant present on the floor surface by using the sensing unit while performing the cleaning operation; and control the cleaning module changing unit to change or maintain the activated cleaning module based on the sensed characteristics of the contaminant.

A power sweeper has a handle having a first end graspable by a user and a second end, a drive shaft extending along the handle, and a power head coupled to the handle to rotate the drive shaft. A gear box is coupled to the drive shaft adjacent the second end, and a brush is coupled to the gear box for rotation in response to rotation of the drive shaft. The power sweeper includes an axle, and first and second wheels coupled to the axle. A shield is coupled to the gear box and defines an aperture through which the handle extends. The axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface.

A surface cleaning apparatus adapted for movement across a surface to be cleaned. The surface cleaning apparatus can dock within a storage tray and charge a power supply. Electrical contacts on the surface cleaning apparatus and the storage tray can be shielded when the surface cleaning apparatus is not docked within the storage tray. Furthermore, the storage tray can include a reservoir for a self-cleaning mode.

Embodiments of the present application provide an intelligent cleaning device, where the intelligent cleaning device includes a device body, a driving wheel assembly, a control circuit, and a transfer circuit; the driving wheel assembly is mounted to the device body from below, and is configured to make the intelligent cleaning device movable; the control circuit is configured to control operation of the intelligent cleaning device, and the control circuit is arranged in the device body; the driving wheel assembly is electrically connected to the control circuit through the transfer circuit, and the transfer circuit is arranged at the device body.

A roller mop capable of self-cleaning, comprising a pull rod (41), a mop head component (1), and a cleaning basin capable of holding the mop head component (1). The pull rod (41) is grasped by a person to operate; a motor (15) in the mop head component (1) drives a roller (10) to clean the ground; after the mopping is ended, the mop head component (1) can be put in the cleaning basin for charging and washing with water. The roller mop provided with a trash bin (17) can receive a number of small trashes; labor intensity is reduced due to the driving of the motor (15); the mop can perform continuous operation, and thus high cleaning efficiency is achieved; moreover, the mop has a self-cleaning effect, and is easy to use.
