A self-propelled robotic pool cleaner includes a housing with a lower portion having an inlet and an upper portion having an outlet, the lower and upper portions define an internal chamber therebetween. A filter and a water pump are mounted in the internal chamber for suctioning pool water into the inlet and discharging filtered water through said outlet. Rotationally-mounted elements are mounted to the housing for supporting and guiding said cleaner on a surface of the pool. An arm assembly extends outward from said housing, and a rotary brush assembly is mounted at a distal end of the arm assembly. An electric motor is coupled to at least one of said water pump, the rotationally-mounted elements and the rotary brush. The pool cleaner is configured to continue climbing upward on a pool wall and tell the rotary brush assembly is above the water level and climbs over the pool coping edge propelling said pool cleaner onto the pool deck.

An electric toothbrush includes a main body, a head connected to the main body, having a stem and a rotating element rotating in first and second rotation directions, a transmission shaft rotating the rotating element, a motor generating rotary motion transmitted via transmission shaft to the rotating element, and first, second and third push switches. Pressing the first switch, which is pressed when the transmission shaft is inclined in a first flexion direction, causes rotation of the rotating element in the first rotation direction. Pressing the second switch, which is pressed when the transmission shaft is inclined in a second flexion direction, causes rotation of the rotating element in the second rotation direction. Pressing the third switch, which is pressed by the transmission shaft when inclined with respect to the main body in a third flexion direction, causes rotation of the rotating element in the first or second rotation direction.

A power toothbrush device (100) including a brush head member (104) having bristles and a drivetrain assembly (400, 800) having a drivetrain shaft (124, 824) configured to drive the brush head member. The drivetrain assembly includes a resonator (410, 810) configured to rotate about a central axis (A) to move the bristles in a first movement pattern; a resilient member (420, 820); a magnet (700A, 700B, 830A, 830B) connected with the resonator; and a conductor (710A, 710B, 840A, 840B). As the resonator rotates and the magnet moves toward the conductor in a first direction, a force is generated upon the magnet in a second direction that is opposite the first direction, and the force generated upon the magnet thereby causes a rotation of the resilient member about a second axis that is different than the central axis.

The present disclosure provides an electric toothbrush that improves a dirt removing effect. Electric toothbrush according to the present disclosure includes: head including brush part; drive unit that operates head; input unit that identifies a type or a position of a tooth to be brushed by brush part; and controller that determines which classification based on a specific criterion the type or the position of the tooth identified by input unit belongs to, and controls drive unit to change an operation of head according to the classification.

The invention relates generally to the field of medical devices and, more specifically, to a handheld device that stimulates the meibomian gland of the eyelid mechanically, and specifically stimulates the meibomian glands of the eyelid to treat Meibomian gland dysfunction, also known as Dry eye and chronic marginal eyelid inflammation.

A device for cleaning a surface (e.g., a barbeque grill, etc.) generally includes an enclosure having at least a lower side, an upper side, and a peripheral edge. The device includes one or more motors having one or more rotational shafts selectively fixable with one or more rotatable brushes. The one or more rotatable brushes have a plurality of bristles. At least a portion of bristles projects below a plane of the lower side of the enclosure. The device also includes a circuit adapted for connecting power from a power source to the one or more motors for a preset period of time upon actuation of an electrical switch connected thereto. The circuit is adapted to run the one or more motors in a first direction and then an opposing direction, such that if the device becomes stuck at an obstruction, it will eventually turn around due to the alternating directions of the one or more motors.

An applicator, also referred to as workpiece, is suitable for use with a personal care appliance. The applicator can be in the form of a dual brush head. The dual brush head includes a movable central portion having first and second independently movable sections.

A dust cleaning device for condenser of cooler is provided. Since the dust from outside is attached to the condenser due to ventilation and they become one of reasons for compressor failure, the device is configured to clean the heat exchange fin of the condenser periodically, in which a wire winch and a cleaning brush is connected to a driving axle of a driving motor such that the cleaning brush performs up-and-down motion and rotation with a power of the driving motor and cleans the heat exchange fin. In other structure, pinion and rack can be connected to the driving axle to perform the up-and-down motion. The cleaning brush is made of textile or unwoven fabric. Furthermore, the cleaning brush further includes a plurality of long brush portions protruding above the cleaning brush.

Provided is a robotic cleaning device, including a chassis, an oscillating mechanism, and a cleaning component, wherein the oscillating mechanism causes the cleaning component to oscillate in at least plane parallel to a driving surface of the robotic cleaning device.

The appliance includes a housing and an attached brushhead which oscillates at a selected frequency and amplitude by a motor and drive system. A system recognizes a hair tangle as the brushhead is drawn through the hair by a decrease in amplitude of movement of the brushhead. A control system changes the operation of the brushhead in response to the recognizing system in such a manner as to untangle the hair.
