A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller. The controller is configured to determine a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.

A brush assembly for a device with a motor for cleaning soldering tools may include a base portion, a brush drive ring, and a locking assembly. The base portion may include a cylindrical core member and a cleaning brush. The cleaning brush may be disposed around a perimeter of the core member and may extend radially away from the core member. The locking assembly may include a first locking member, a second locking member, and an annular retention member. The first and second locking members may be configured to interface with one another. The annular retention member may define a resting state for the locking assembly, in which the first and second locking members may grip a shaft of the motor. The annular retention member may also define a transient state for the locking assembly, in which the first and second locking members may move out of the resting state.

The invention relates to a brush head for an electric toothbrush comprising a brush head shaft (20) with two ends, one end (21) with a tuft plate (30) being oscillatable about its centre axis, and one end adapted for detachable connection to a handle of the electric toothbrush, wherein the oscillatable tuft plate comprises at least three tufts (40), each tuft being non-rotatably attached to the tuft plate, wherein each tuft comprises a free end (41) and an end (42) fixedly attached to the oscillatable tuft plate.

A substrate treatment apparatus includes a brush moving mechanism which moves a shaft to which a cleaning brush is attached. The brush body includes a substrate contact portion of a pillar-shaped portion. The substrate treatment apparatus further includes a correcting member and a relatively-positioning mechanism. When the correcting member is placed in a target position, a contact portion of the correcting member overlaps an object portion which is a combination of a design contact portion and a belt-shaped annular portion in an outer surface of a design pillar-shaped portion of a design body of a design brush. The contact portion is formed to have an inverted shape of the object portion of the design brush, and a portion of the contact portion, which corresponds to the belt-shaped annular portion, is a center-axis facing surface which faces a center axis of the shaft.

A housing has a rearward end with a handle. The housing has a forward end with a motor housing and a laterally spaced guard housing. The housing has a housing axis extending between the forward end and the rearward end. The guard housing is located to the left side of the forward end. A motor located within the motor housing has a drive shaft rotatable around a horizontal axis of rotation perpendicular with the housing axis and extending into the guard housing. A brush wheel mounted on the drive shaft rotates with the drive shaft for brushing and cleaning small bathroom grout, tub and shower walls and floors, kitchen and bathroom sinks, especially under-mounted, around windows and more.

The Pro Sponge Rejuvenator is sponge cleaner for cleaning a plurality of used sponges, comprising: a liquid-tight container in which stems which extend from a platform toward a bottom of the container are oscillate-able to rub the sponges against the bottom by an oscillation means connected to the platform and supported by the bottom. The Pro Sponge Rejuvenator cleans sponges using a cleaning solution that is filtered with every sponge cleaning oscillation up/down stroke of the apparatus through the use of one-way flow valves under the sponges and a central tube with filter media. The Pro Sponge Rejuvenator is ideal for cleaning sponges and especially cosmetics makeup sponges.

A cleaning system comprises a first cleaning tank, a carrying and moving unit, a first cleaning spray head, and a rolling brush unit. The carrying and moving unit is configured to move a polishing film to be cleaned into the first cleaning tank and hold the polishing film in the first cleaning tank. The first cleaning spray head is configured to spray a cleaning liquid on the polishing film held in the first cleaning tank. The rolling brush unit is configured to brush the polishing film while the first cleaning spray head sprays the cleaning liquid on the polishing film.

A fluid flow actuated tool including a housing, a tool and an actuating mechanism. The housing includes a housing interior. The housing interior receives a flow of fluid. The actuating mechanism includes a fluid wheel structure. The fluid wheel structure is connected to the tool. At least a portion of the fluid wheel structure is arranged in the flow of fluid for rotating the fluid wheel structure. The tool is actuated based on rotation of the fluid wheel structure.

The baseboard-cleaning implement is a handheld device. The baseboard-cleaning implement is a hand tool. The baseboard-cleaning implement is configured for use in cleaning a baseboard. The baseboard-cleaning implement is a cleaning brush. The baseboard-cleaning implement is configured for use with a liquid soap. The baseboard-cleaning implement includes a handle, a plurality of interchangeable brushes, a fastener, and a control circuit. The fastener removably attaches any brush selected from the plurality of interchangeable brushes to the handle. The handle contains the control circuit. The control circuit pumps the liquid soap from the handle into the selected brush. The control circuit rotates any brush selected from the plurality of interchangeable brushes. The direction of rotation of the selected brush is selectable.

Systems and methods are provided for cleaning a cloth or fabric that has been used for growing plants. The cloth or fabric may be separated from or mounted with respect to a tray or support during the cleaning operation. At least two opposed, rotating brushes engage the top and bottom surfaces of the cloth or fabric to abrade and clean those surfaces. In addition, spray units, e.g., high pressure fluid nozzles, may direct cleaning fluid against one or both surfaces of the cloth or fabric. Filtration and sterilization systems may also be associated with the cleaning operation.
