A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.

A cosmetic brush cleaning device, comprising a support part (1) and a cleaning part (2). The support part (1) and the cleaning part (2) form a hourglass-shaped structure; and the cleaning part (2) is rotationally arranged at the top of the support part (1). The cleaning device can perform the action of back-and-forth friction between bristles and a silica gel inner rotary disc (22) in an electric manner, the cleaning efficiency is effectively improved, the cleaning effect can be effectively enhanced, the tedious manual back-and-forth movement is greatly reduced, and the problem that time and labor are wasted when a cosmetic brush is manually cleaned is solved.

An electrically operated assembly comprises a handle housing defining an inner cavity, a connector for repeatably attaching and detaching a head to and from the assembly, and a motor for operating the assembly, wherein the connector comprises a recess in which the motor is accommodated, and the connector is at least partially made from a material having an e-modulus being higher than the e-modulus of the material from which the handle housing is made.

The group of inventions can be used for removal of deposits in sewers and the simultaneous removal thereof in various pipelines, providing mechanization of the cleaning process in a sewage pipeline and eliminating the need for disassembling the drain system and manually cleaning it. A movable element and a cleaning tool mounted thereon, both arranged within the sewage pipeline, are moved along the sewage pipeline by means of a drive mounted outside the sewage pipeline and connected to the movable element. In the initial position, the cleaning tool is located at the end of the sewage pipeline, outside the sewage pipeline portion connecting the drain pipe with a riser. When the cleaning tool reaches the end position at the junction of the sewage pipeline and the riser, the drive and the movable element move the cleaning tool to its initial position.

The present disclosure relates to an apparatus and a method for wafer cleaning. The apparatus can include a wafer holder configured to hold a wafer; a cleaning nozzle configured to dispense a cleaning fluid onto a first surface (e.g., front surface) of the wafer; and a cleaning brush configured to clean a second surface (e.g., back surface) of the wafer. Using the cleaning fluid, the cleaning brush can clean the second surface of the wafer with a scrubbing motion and ultrasonic vibration.

Conventionally, cleaning of objects has been proposed by use of gloves wherein objects need to be pre-washed manually. However, the level of cleaning is not spotless. Electric scrubbers have also been proposed in solving scrubbing problem but are not efficient. Embodiment of the present disclosure provide a glove that integrates a detachable power-driven scrubber. The power-driven scrubber is configured to controllably rotate in one or more directions based on an activation of a sensor to clean an object. The glove further includes sensing mechanisms for controlled flow of water discharge and controlled flow of cleansing fluid dispense that enables the detachable power-driven scrubber to clean the object. Rotation of the detachable power-driven scrubber is controlled and driven by a drive shaft that transmits rotary motion/torque generated by a motor coupled thereto. A scrubber locking strap is provided on the glove for lock and release of the detachable power-driven scrubber accordingly.
