An apparatus comprising a first motor to control a rotation and a second motor to control a vibration of a moving portion of the apparatus. In one embodiment, the apparatus further comprises a controller to control of a ratio between the rotation and the vibration.

A low-power system for cleaning an underwater object, comprising an autonomous vehicle configured to move along a surface of an underwater object to be cleaned, the autonomous vehicle including a cleaning device. The cleaning device is configured to remove biofouling from the surface of the underwater object. The autonomous vehicle further includes a variable buoyancy mechanism configured to control a buoyancy of the autonomous vehicle, such that the autonomous vehicle moves up and/or down an underwater object.

A cleaning device including a covering hood having a lower surface facing a surface to be cleaned and an inlet on an upper surface thereof, through which contaminants are sucked; an air knife provided on a circumference of the covering hood and having an outlet for spraying high pressure air to the surface to be cleaned; a sweeper installed inside the covering hood and rotated by a driving motor to guide foreign objects swept away from the surface to be cleaned and contaminants floated by the high pressure air injection of the air knife to the inlet; a rotary member including a shaft passing through a circumferential surface of the covering hood and the air knife, and a rotary knob coupled to one end of the shaft to rotate the air knife to adjust an air spray angle.

The skin treatment device also includes a heating element and a heat transfer mechanism to produce and transfer heat therapy to a user. The skin treatment device further includes at least one stimulation mechanism configured to transfer electrical current stimulation to a user.

The present disclosure relates generally to an apparatus for cleaning or otherwise treating a floor or ground surface. Devices provided herein include various features to enhance the efficiency and efficacy of cleaning operations. Such devices includes, but are not limited to, bearing protector devices, cord and cable management devices, and ergonomic features useful with ride-on floor treating machines.

A cleaning method and apparatus for elevated structures and ceilings, such as open girder truss systems, utilizes a multi-rotor blade helicopter/drone together with a contaminant entrainment system. More specifically, the drone includes a contaminant entrainment system including a vacuum and filter for entraining the contaminants dislodged from the elevated structures, a cleaning head to engage the surface to be cleaned, a system to guide the drone's flight path proximate the elevated structures to be cleaned, and optionally a power tether to reduce battery weight and increase the flight time of the drone.

A vehicle wash system includes a vehicle treatment area and an overhead frame portion supporting a pair of side brushes. The side brushes are configured to treat the lateral sides of the vehicle and may also treat the front and back of the vehicle. The side brushes are configured to pivot between a vertical position and an outwardly angled position, in which the side brushes are generally aligned with the side glass of the vehicle windows. The side brushes may travel along the side of the vehicle in both the vertical and pivoted orientations. The side brushes may make multiple passes along the side of the vehicle, and the side brushes may change orientation during or between passes to treat different segments of the vehicle. The side brushes may be oriented vertically at a location of a vehicle antenna to avoid the antenna.

In a substrate cleaning device, with a polishing head in contact with one surface of a substrate rotated by a spin chuck, the polishing head is moved at least between a center and an outer periphery of the substrate. Thus, the one surface of the substrate is polished by the polishing head, and contaminants present on the one surface of the substrate are removed. At this time, capacity for removing contaminants by the polishing head is changed according to a position in a radial direction of the substrate. The capacity for removing contaminants refers to capacity for scraping contaminants adhering to the one surface of the substrate, and suction marks, contact marks and the like remaining on the one surface of the substrate by polishing. It is possible to change the capacity for removing contaminants by adjusting a pushing force exerted on the one surface of the substrate from the polishing head, for example.

A cleaning brush comprising a carrier and a cleaning unit is provided. The cleaning unit comprises a plurality of cleaning beans set on a surface of the carrier in a spiral arrangement. A spiral coiling around the carrier from an end of the carrier to the other end is formed. A spiral curve path is formed to coil the carrier circumferentially by extendedly arranging the cleaning beans. Hence, the present invention uses the cleaning beans of the cleaning unit to be set on surface of the carrier. On rotating in a fixed direction, the spiral cleaning unit generates a flow field which not only comprises a vertical flow for an object to be cleaned but also a horizontal flow forming a parallel stream. Thus, dirt can be removed more easily than by using a traditional matrix cleaning device.

A representative cleaning tool includes: a valve assembly having an inlet, a first outlet, a second outlet and an actuator, the inlet configured to receive a flow of water, the first outlet fluidly communicating with a first conduit, the second outlet fluidly communicating with a second conduit, and the actuator configured to selectively direct the flow of water from the inlet based on a position of the actuator; a mixing assembly fluidly communicating with the second conduit; a detergent reservoir fluidly communicating with the mixing assembly and configured to receive therein a supply of detergent, wherein, based on the actuator being in the second position, the valve assembly directs the flow of water to the mixing assembly, which draws a portion of the supply of detergent from the detergent reservoir and mixes the water and the detergent to form foam that is directed through the second conduit; and a handle configured to be gripped by a hand of a user, wherein the actuator is configured to be moved by the hand of the user while gripping the handle.
