Abstract: Disclosed herein is an autonomous cleaning machine with a brush cleaning unit to clean a brush unit. The autonomous cleaning machine includes a main body, the brush unit rotatably provided on the main body, first brush cleaning members contacting the brush unit to move foreign substances wound on the brush unit in a lengthwise direction of the brush unit, and second brush cleaning members contacting the brush unit to remove the foreign substances wound on the brush unit from the brush unit.

Abstract: The present invention relates to a wiper blade system that includes a wiper blade assembly having a wiping element, at least one elongated beam and a carrier that is operatively engaged to the elongated beam. The wiper blade assembly further includes an airfoil and a coupler that is removably engaged to the carrier and adapted to releasably attach the wiper blade assembly to a wiper arm attachment member. The coupler is universal in that it is used for connecting the wiper blade assembly to various styles of wiper arms.

Abstract: An imaging method is disclosed that is implemented in an image forming apparatus for forming a tone pattern on a recording medium by forming an arrangement of dots on the recording medium. The arrangement of dots is formed on the recording medium by jetting a recording liquid from a recording head while moving the recording head in a main scanning direction a plurality of times and intermittently conveying the recording medium in a sub-scanning direction that perpendicularly intersects the main scanning direction. The imaging method involves forming the arrangement of dots such that dots belonging to a first group that are consecutively aligned in a base tone direction and dots belonging to a second group that are consecutively aligned in the sub scanning direction are respectively formed in non-consecutive order on the recording medium.

Abstract: A manually-powered floor sweeper is provided according to the invention. In one embodiment, the manually-powered floor sweeper includes a chassis and handle, one or more agitator rollers rotatably affixed to the chassis and rotated by movement of the floor sweeper, and a vacuum port formed in the chassis and communicating with the one or more agitator rollers and adapted to receive a vacuum hose. Debris picked up and propelled by the one or more agitator rollers is drawn out through the vacuum port when a vacuum is introduced into the vacuum port.

Abstract: A rug cleaning apparatus comprises a housing having a front wall, a back wall, a top, and a pair of opposite end walls. An opening is formed in the top for allowing insertion of a rug into the apparatus, and a driven roller brush is mounted in the apparatus and extends from one to another of the pair of end walls. The roller brush has bristles extending therefrom for brushing against a rug inserted into the apparatus with at least a portion of the bristles being removed from the roller brush such that during a predetermined portion of rotation of the roller brush a portion of the rug is not in contact with brush bristles. Means attached to the apparatus and positioned adjacent the driven roller urge a rug into contact with the roller brush for brushing debris from the rug and for effecting vibration of the rug by repeated contact and lost of contact between the rug and bristles on the rug.

Abstract: A floor cleaner has driven rollers integrally mounted with a pair of rotating cleaning bodies on respective opposite end portions thereof, each of the rotating cleaning body being provided with a plurality of blades made of an elastic material, and wheels including a pair each of main wheels disposed at forward and rear portions of the casing and auxiliary wheels each of which is located at an intermediate position defined between the respective rotating bodies and main wheels. Each of the auxiliary wheels is positioned somewhat lower than the respective main wheels, i.e. they are collectively arranged in a seesaw-like condition. The main wheels and the auxiliary wheels are journaled to the casing in such a manner that both are swingable toward the front and the rear of the casing. Idle rollers are journaled to the casing between the respective main wheels and the respective driven rollers in a swingable manner.

Abstract: A rotary cleaning member comprises a revolving shaft installed rotatably inside a main body casing, and a plurality of flexible blades provided with a number of projections on the surface thereof abutting upon the surface of a floor, these blades extending radially from the circumference of the revolving shaft one another in a cleaner wherein the rotary cleaning member installed in the main body casing is rotated to spring up dust or the like on the floor, or convey the dust or the like sprung up by means of said rotary cleaning member to a prescribed position for receiving the dust or the like in combination with suction.

Abstract: A miniature electrically powered surface sweeper having a rotary brush element which is adapted to come in direct contact with a surface to be cleaned. The brush element is disposed within a housing having a curved inner wall surface which contacts the bristles as the same move inwardly within the housing to prevent loss of dust particles. A receptacle element is provided with a movable trap opened by the moving of an electrical switch to closed position to power the brush element, and closed when the switch is opened to discontinue operation of the brush element. The brush element includes bristles which are formed of cutting a planar sheet of synthetic resinous material to form flat bristles attached to a base, the base being in turn attached to an outer surface of a rotating drum member to permit convenient replacement.
