This application discloses a side brush and a smart cleaning device. The side brush includes a side brush base for mounting to a smart cleaning device and a scraper connected to a peripheral side of the side brush base. The scraper is configured to be in contact with the floor, so as to scrape sundries. A structure of the side brush can effectively prevent the side brush from being entangled with sundries during cleaning.

A cleaning head for a floor cleaner including a brushroll assembly configured to clean a surface to be cleaned and reduce brushroll maintenance, such as removing hair and debris wrapped around the brushroll assembly and removing debris from a bearing of the brushroll assembly. The brushroll assembly may comprise agitator members to assist in cleaning and maintenance.

In order to provide a dust-containing gas treatment apparatus which can smoothly achieve the treatment of gas containing dust of high concentration, the apparatus is equipped with a cylindrical treatment room to introduce gas containing dust and remove the dust from the gas, catcher consisting of brush with the hair planted in the support installed in the treatment room to catch the dust contained in the gas, liquid spraying mechanism installed in the treatment room, rotary driving mechanism to rotate the catcher and stirrer, gas introducing portion to introduce the gas containing dust, gas discharging portion to discharge the gas, the dust removed, from the treatment room and liquid discharging portion to discharge the liquid containing the dust removed from the gas.

A hand-held rotary tool includes a housing that encloses a motor having an output shaft. The tool includes a quick connect adaptor configured to connect an accessory to the output shaft. The adaptor includes a driver that is connected to the output shaft and rotates in concert with the output shaft. An outer surface of the driver has a first flat. The adaptor includes a receiver that includes a connector configured to detachably connect with the housing, and a torque transfer device configured to receive the driver. An inner surface of the torque transfer device includes a second flat that engages with the first flat in such a way that rotation of the driver results in rotation the torque transfer device relative to the connector. The adaptor includes an output device that supports the accessory and that is driven by the torque transfer device to move relative to the connector.

A cleaning device for providing a pocket-sized, hand-held toilet seat cleaning device that releases a sanitation solution via a disposable cleaning head is disclosed. The cleaning device includes an antibacterial chamber for holding sanitation solution having top and bottom ends, a handle coupled to the top end of the antibacterial chamber; and a removable cleaning component coupled to the bottom end of the antibacterial chamber. The sanitation solution flows from the antibacterial chamber through the cleaning component under the control of a release device.

A pan cleaning system is provided having a support carriage with one or more track supports and one or more track guides. An indexing conveyor provides a stream of baking pans and indexes the pans onto the support carriage as single pans. One or more twists in the track supports are provided such that the pans admitted by the indexing conveyor are turned at least substantially perpendicular relative to the horizontal plane of the machine. One or more frame assemblies having one or more sets of swing arms mounted on it is provided. With one or more secondary conveyors coupled to th frame assemblies. One or more cleaning subsystems are releasably coupled to the swing arms. A controller is provided where the single baking pan is admitted via the indexing conveyor based on signals from the controller into the one or more track guides as supported by the one or more supports and conveyed by the support carriage along the track guides and into the one or more frame assemblies after the twist turns the pan at least substantially perpendicular and the pan engages the one or more secondary conveyors and the pans is conveyed by the support carriage and the secondary conveyor to one or more cleaning subsystems.

A cleaning brush is provided. A cleaning unit comprises cleaning beans fixed on a surface of the carrier in a bi-spiral arrangement. The cleaning beans are arranged in an unequally-spaced manner on center of the carrier along a baseline; and, thus, bi-spirals are formed on the center and coiled in two different outward directions. Two annular spiral curve paths are formed with the cleaning beans as coiling the carrier and extending along the two directions. When the carrier cleans an electronic device, a solution or cleaning agent is discharged along the curve paths in spiral tangential directions. Hence, the bi-spiral cleaning unit obtains positive and negative directions on rotating to create a plurality of flow fields. Dirt is discharged easily with water distribution enhanced as compared to unidirectional spiral cleaning devices while a large contact surface, a good cleaning efficiency, and a high decontamination ratio are achieved.

A tool and methods of removing films from bevel regions of wafers are disclosed. The bevel film removal tool includes an inner motor nested within an outer motor and a bevel brush secured to the outer motor. The bevel brush is adjustable radially outward to allow the wafer to be inserted in the bevel brush and to be secured to the inner motor. The bevel brush is adjustable radially inward to engage one or more sections of the bevel brush and to bring the bevel brush in contact with a bevel region of the wafer. Once engaged, a solution may be dispensed at the engaged sections of the bevel brush and the inner motor and the outer motor may be rotated such that the bevel brush is rotated against the wafer such that the bevel films of the wafer are both chemically and mechanically removed.

A device for cleaning and organizing sheetrock knives is disclosed. The device includes a panel having an orifice covered on at least one side with brush bristles. The panel has at least one slot for holding sheetrock knives and may contain additional compartments for holding utility knives and pencils. When a user places the device in a five gallon bucket, she may rinse and brush sheet rock knives using the orifice and cleaning liquid in the bucket or she may store the knives and other tools in the slots and other compartments.

The cleaning device (20) for cleaning a cylindrical roller (50), for example an anilox roller of a printing machine, includes a cleaning head (30) with a cleaning chamber (110), in which there is housed a mechanical cleaning member (60), and with which there are associated feeding members (70) for feeding a cleaning liquid into the cleaning chamber (110). The mechanical member (60) and cleaning liquid dispensed by the feeding members work in combination inside said cleaning chamber (110) to clean the lateral surface of the roller (50)
