A cleaning head for a personal care appliance includes an elastic bladder having a bladder wall enclosing a fluid. The bladder wall has an inner base portion with a base thickness, which may be non-uniform, and a plurality of spaced projections extending outwardly from the inner base portion. The bladder is fixedly attached to a receiver portion of a bladder support, and a retainer is provided for attaching the bladder support to the personal care appliance such that the bladder support is drivably engaged by the personal care appliance. At least some of the plurality of spaced projections are configured to dynamically engage and disengage with neighboring ones of the plurality of spaced projections during use.

A brush construction for motor vehicle washing systems comprises a base plate (2) that supports a plurality of bristles (3) each of which has a base end (31), fixed to the plate (2), and a free end (32); the base plate (2) is suitable for being removably fixed to a rotating construction that is suitable for rotating the base plate (2) around the central axis thereof; the bristles (3) are fixed to the base plate (2) with different tilts both in radial directions, inwardly and outwardly, both in non-radial directions, clockwise and anticlockwise, with respect to the rotation direction of the base plate (2) or in any other direction that is different from the preceding directions; the bristles (3) being arranged with mutually converging and/or diverging tilt directions.

The present invention discloses a foam cleansing instrument, including a base, a liquid injection bottle, a cleansing head, and a foaming pump. The base has a bottle mounting position. The liquid injection bottle is detachably mounted in the bottle mounting position, and enables a cleanser in the liquid injection bottle to flow downward to a bottle mouth of the liquid injection bottle by its own gravity. The cleansing head is arranged on the base and configured to fit a human face to smear foam on the human face. The foaming pump is connected to the bottle mouth of the liquid injection bottle through a liquid inlet pipe and connected to the cleansing head through a liquid outlet pipe; and at least one of the liquid inlet pipe and the liquid outlet pipe is connected to a foam maker. The foam cleansing instrument is more convenient to use

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.

The present disclosure provides a roller for cleaning a backside of a wafer. The backside of the wafer has a central region and a periphery region surrounding the central region. The roller includes an upper element, a bottom element, and an axis element for connecting the upper element and the bottom element. The upper element of the roller is configured to contact with a frontside of the wafer. The bottom element is configured to contact with the backside of the wafer and remove particles from the periphery region of the backside of the wafer. The bottom element is made of materials selected from a group comprising abrasive pads, sand papers, and asbestos.

A floor cleaning machine having a cleaning element arrangement with inner and outer cleaning elements that include inner and outer cleaning bodies, respectively, that extend jointly in the cleaning body plane and have first and second receiving openings, respectively. The inner and outer cleaning elements extend from the inner and outer cleaning bodies, respectively, away from the cleaning body plane to one side thereof. The inner cleaning body is arranged in the second receiving opening. The output shaft extends with an output shaft section into both the first and second receiving openings. First and second eccentric elements are attached to the output shaft section and to the inner and outer cleaning bodies, respectively, so that when the output shaft is rotated, the inner and outer cleaning bodies perform eccentric movements that are phase-shifted with respect to one another.

The rotating lotion dispensing body brush is a brush. The rotating lotion dispensing body brush is adapted for use with a patient. The rotating lotion dispensing body brush is configured for use with a lotion. The rotating lotion dispensing body brush applies the lotion to the patient. The rotating lotion dispensing body brush comprises a brush structure, a control circuit, and a fluidic network. The brush structure contains the lotion, the control circuit, and the fluidic network. The control circuit pumps the lotion through the fluidic network. The control circuit rotates the brush structure. The fluidic network transports the lotion from the brush head to the patient.
