A vacuum tool is configured to be removably coupled to a hose or wand of a vacuum. The vacuum tool comprises a first portion, a second portion, a flexible portion and a mechanical joint. The first portion and the second portion are connected by the flexible portion and coupled by the mechanical joint, so these portions are in fluid communication from various angles. And the mechanical joint comprises a detent and multiple recesses coupled to the detent. As a result, a user can use the vacuum tool in various situations more conveniently by bending the mechanical joint.

An apparatus for cleaning earphones that includes a brush element, a positioning element, and a motive element. A brush element selectively contacts and removes debris from an earphone, and a positioning element supports the earphone in a desired position relative to the brush element. A motive element is configured to move the brush element relative to the earphone. A corresponding system and method are also disclosed and claimed herein.

Methods and devices relating to loose debris chip shielding for dust free tile removal and ordinary tile removal projects. During the tile removal process, a chipping hammer powers a chipping hammer blade that breaks up tiles into pieces. The larger, heavier pieces are simply pushed away, but smaller debris chips break off with enough force to send them flying up in the air and in different directions landing in undesirable locations. The methods and devices herein protect equipment, environments, and individuals from damage caused by loose debris chips during tile removal. A shield with several degrees of freedom moves freely in response to chipping hammer vibrations and blocks loose flying debris chips, deflecting them toward the ground.

An automatic cleaning unit for AMHS includes a plurality of sensors disposed on OHT rails. The sensors are configured to define a cleaning zone and to detect a location of an OHT vehicle. The automatic cleaning unit further includes a vacuum generator and a top cleaning part installed over the OHT rails in the cleaning zone. The top cleaning part is coupled to the vacuum generator. The vacuum generator is turned on to perform a vacuum cleaning operation when the sensors detect the OHT vehicle entering the cleaning zone.

A surface cleaning apparatus such as an extractor has a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid and an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated fluid outlet conduit. A solid and liquid collection chamber is in communication with the separated element outlet.

A vacuum housing attachment used with a animal grooming tool for vacuuming loose fur and hair as an animal is groomed The housing attachment includes an inverted “U” shaped tool housing. The tool housing includes an open bottom portion, a closed first end portion and an open second end portion. The open second end portion is adapted for receiving the grooming tool therethrough. The tool housing is adapted for holding the grooming tool in a snug fit. Attached to a rear portion of the tool housing is a hollow handle. One end of the hollow handle includes a vacuum intake port for receiving the fur or hair from an animal, as the animal is being groomed. An opposite end of the hollow handle includes a vacuum exit port adapted for attachment to a vacuum tube.

The present invention is directed to a compact robotic device for spraying a biocide powder or liquid to a predetermined area for controlling the infestation by cockroaches and fleas. The compact robotic device comprises a robotic body that can autonomously travel to spray the powder or liquid. The compact robotic device comprises a cartridge containing the biocide powder, a spray head in fluid communication with the cartridge and configured to spray the powder or liquid over a surface and a pump coupled to the cartridge for affecting the flow of powder or liquid from the cartridge to the spray head.

A cleaning device comprises a surface interaction layer (ML), a cleaning fluid supply (CFF) provided with a cleaning fluid channel (CFC) at the surface interaction layer (ML) for supplying a cleaning fluid to a surface (F) through the surface interaction layer (ML) being in contact with the surface (F), and a dirty fluid drain (DFD) having a dirty fluid channel (DFC) at the surface interaction layer (ML) for draining, by means of underpressure, dirty water from the surface (F) through the surface interaction layer (ML) being in contact with the surface (F).
