A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. On the base member is one or more engagement members, such as lugs, protrusions or frustums. On the lower surface of one of the engagement members is one or more striations, ribs, squeegees or ridges. The striations, ribs, squeegees or ridges operate in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. This operational engagement position for the striations, ribs, squeegees or ridges is one of a number of other operational engagement positions for the pet hair removal apparatus.

The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

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.

A substrate-cleaning apparatus may include a tilting arm to which a roll brush and a motor are coupled, a support arm positioned on the tilting arm, a first spring and a second spring coupling the tilting arm to the support arm, a first air bag and a second air bag mounted between the tilting arm and the support arm, and a controller configured to adjust an internal pressure of each of the first air bag and the second air bag. The controller may adjust a difference in internal pressure between the first air bag and the second air bag to control the inclination of the roll brush, and may adjust the internal pressure of each of the first air bag and the second air bag to move the roll brush vertically.

The invention relates to an improved system, device and method for optimized, high volume cleaning of pans, related brush modules, and methods of operating and processing same A pan cleaning system having one or more modular swing arms for cleaning a flow of pans is provided. The system having a frame with a mounting point for each of the modular swing arms and the swing arm pivots about a pivoting element freely motivated by a swing arm actuator and controlled with a swing arm limiter coupled to one or more controllers. The modular swing arm is positioned by the one or more controllers by activating the swing arm actuator to position and to engage a dirty pan from the flow of pans at a pressure range exerted by the actuator and limited by the swing arm limiter such that the pan is cleaned. On one of the modular swing arms, a cleaning module mounting a staggered set of two or more brush heads is provided in offset rows provides overlap during cleaning to overcome compression issues in the brush heads during movement of the pan. Each of the brush heads also having bristles specifically spaced and angled so that they provide consistent contact without laying over one another when compression does occur. Each of the brush heads also rotating so that the rotational moments of each of the brush heads in the two or more brush heads is offset by the equal or paired rotating brush heads. Finally, the controller is provided so that it can sense numerous conditions in the cleaning process, including things like pan height, pan type, the amount of contaminants on the pan, the size of the pan, how much agitation or pressure to apply to the pan, when the pan is passing the cleaning module, whether a jam may be occurring under the module, and similar variables during the cleaning process.

A power tool is advantageously configured to provide a rotating motion, an oscillating motion, and a reciprocating motion. The power tool includes at least one motor, which is operable to drive these three different motions at the same time. The power tool includes a rotating member, which is configured to output a rotating motion. The rotating member is configured to attach to and detach from a rotating accessory. The power tool includes an oscillating member, which is configured to output an oscillating motion. The oscillating member is configured to attach to and detach from an oscillating accessory. The power tool includes a pin, which is configured to output a reciprocating motion. The pin is configured to provide the reciprocating motion to a reciprocating accessory. The power tool is configured to provide a connected accessory with the corresponding motion during operation.

A vacuum head comprising an outer shell having a lower ventral wall and an upper dorsal wall, a harness attached to the dorsal wall, a base brush extending downward from the ventral wall, an inlet positioned at an anterior end of the outer shell, an outlet positioned at a posterior end of the outer shell, and an inner channel fluidly connecting the inlet to the outlet.

A mobile trailer-cleaning system is a system that facilitates the cleaning of the exterior surfaces of a trailer. The system may include at least one brush assembly, a roof carriage, an agitation mechanism, and a steering assembly. The at least one brush assembly enables the cleaning of all the trailer's exterior surfaces including the rear of the trailer and any non-flat surfaces. The roof carriage serves as a guide to maintain the at least one brush assembly adjacent to the trailer's walls as the at least one brush assembly moves along the trailer. The roof carriage also prevents the at least one brush assembly from tipping over. The agitation mechanism eases the cleaning of the trailer's exterior surfaces by agitating the at least one brush assembly in predetermined modes of operation. The steering assembly enables the user to manually operate the at least one brush assembly during the cleaning process.

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.

A pool cleaner equipped with a rotating brush assembly is disclosed. The brush assembly is removably coupled to the pool cleaner using clamps that are readily accessible, supported by the pool cleaner, and operable by hand. The clamps may be manipulated between a ready configuration, a loaded configuration to receive a brush assembly, and a locked configuration to secure the brush assembly.
