A cleaning device that passively self-adjusts to improve biofoul removal across curved, non-uniform, or irregular underwater surfaces. The cleaning device includes a motor, one or more shafts coupled to the motor and coupled to one another via at least one universal joint, and a cleaning mechanism for removing biofoul from the target surface. The cleaning device includes an alignment mechanism that restricts the cleaning mechanism's movement to improve biofoul removal. The alignment mechanism can include bearings, spring components, dampening material, adhesion components, floatation objects, or a combination thereof.

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

A denture brush that includes a frame having a plurality of wall pieces disposed at an outer circumferential part of a flat plate-shaped base, and first bristle tufts are arrayed on the wall pieces, and second bristle tufts 6 are arrayed in a center region of the base, and third bristle tufts are arrayed on an outer circumferential side of the second bristle tufts. When the denture brush is not housed in a holder, the wall pieces are positioned radially along the outer circumferential part of the base so as to be horizontal with respect to the base. When the denture brush is housed in the holder, the wall pieces are supported by a wall surface of a denture-brush-housing portion of the holder, and are positioned so as to stand upright with respect to the base.

Discussed is a skin care device comprising: a main body having a processor, and an ultrasonic vibrator assembly disposed on one end of the main body and forming a contact surface with a skin of a user, wherein the processor controls the ultrasonic vibrator assembly to apply an ultrasonic vibration to the skin according to at least one of a frequency characteristic, an output characteristic, and a duty ratio characteristic for removing wastes on a surface of the skin.

Disclosed herein is an improved eyelid care appliance and method of using such appliance for preventing and treating blepharitis and mammalian meibomian gland dysfunction caused by gland obstruction. The method and apparatus of the invention enable restoration and maintenance of eyelid hygiene and the natural flow of secretions from the meibomian glands. A preferred embodiment of the apparatus has an oscillating brush head affixed to the distal end of the eyelid care appliance. The brush head can be impregnated with topical pharmacologic or cleansing agents to better facilitate cleaning and therapeutic efficacy.

A wall-mounted back scrubber apparatus for cleaning one's back in the shower includes a housing having a housing defining a housing inside. The housing front side has a central aperture and a plurality of secondary apertures extending through to the housing inside. A plurality of suction cups is coupled to the housing back side and is configured to selectively engage a shower wall. A motor is coupled to the housing within the housing inside and has a motor shaft extending through the central aperture. A central brush is coupled to the motor shaft and a central gear is coupled to the motor shaft within the housing inside to drive a plurality of secondary gears attached to a plurality of gear shafts coupled to the housing back side and extending through the plurality of secondary apertures. A plurality of secondary brushes is coupled to the plurality of gear shafts.

A motorized hairbrush includes a bristle securing base including a first recessed cavity formed in the bristle securing base. A handle is coupled to the bristle securing base. The handle includes a second recessed cavity facing the first recessed cavity. A vibrating motor is disposed in the first recessed cavity. A battery is electrically connected to the vibrating motor. An activation switch is coupled to the battery and is configured to activate the vibrating motor.

A personal care system having a treatment device for applying a treatment to the skin or hair of a user is provided. The treatment device has a camera for taking an image of the skin. The system may include or be in communication with an application programming interface (API) that can process the image. The system or an associated API can recommend the use of treatment regimens or topical products according to information determined from the digital image of the skin.

A method for cleaning a surface that is selected from at least one of a medical device surface and a soft tissue surface includes the steps of: contacting the surface with bristles of a moving brush head that is part of a powered hand-held device; and dispensing onto the surface an irrigation fluid through the brush head and a dispensing opening formed along the brush head.

A power scrubber including a telescopic shaft, a power receptacle, a handle, a power head, a pivot coupling, a first scrubber head, a second scrubber head, and a drive. The power receptacle and the handle are each positioned adjacent the first end. The pivot coupling couples the power head to the second end and is operable to adjust an angle of the power head relative to the shaft axis. The drive is coupled to and driven by the power head and extends along a longitudinal axis. The drive includes a first connector selectively engaging the first scrubber head with a center of the first scrubber head aligned with the longitudinal axis and a second connector selectively engaging the second scrubber head with a center of the second scrubber head aligned with the longitudinal axis. The first connector is connected to the first scrubber by a bayonet coupling.
