| 20100005606 | CLEANING APPARATUS FOR A PREFERABLY PLANAR SURFACE - A cleaning apparatus is provided for a preferably planar surface, in particular a window pane, and has a wiping device and a plunger which keeps the wiping device in contact with the surface and also, by way of an open side, bears against the surface and seals it around the edge. A suction device generates a negative pressure in the plunger. The plunger is provided with driving rollers, which are actuated by motor, for moving the plunger together with the wiping device. The suction device has at least two fans which are each provided with their own outlet opening. | 01-14-2010 |
| 20110197381 | WIPER WITH RECIPROCATING CLEANING APPARATUS - A scrubber assembly includes a scrubber support structure, an elongated scrubber element and a motor. The scrubber support structure is configured to attach to a windshield wiper. The scrubber element is movably attached to the scrubber support structure and extends between a first end and a spaced apart second end along a central longitudinal axis. The motor is mounted to the scrubber support structure and is engaged with the scrubber element to reciprocally move the scrubber element along the central longitudinal axis. A portable power source mounted to the scrubber support structure may provide power to the motor. | 08-18-2011 |
| 20120110759 | AUTOMATIC CLEANER - Provided is an automatic cleaner, which includes a first moving part, a second moving part, a moving wheel, a driving motor, a fixing member, and a control part. The first moving part is movably disposed at a side of an object to be cleaned. The second moving part is movably disposed at another side of the object. The moving wheel is disposed on at least one of the first moving part and the second moving part. The driving motor provides driving force to the moving wheel. The fixing member fixes the first moving part and the second moving part to each other through the object. The control part increases or decreases the driving force output from the driving motor according to a moving direction of the first or second moving part. | 05-10-2012 |
| 20130055516 | GLASS SURFACE CLEANING DEVICE - A cleaning device includes a first expansion unit in which a first expansion member is received and the first expansion unit is connected to a cylinder which has a piston received therein and the piston defines a first room and a second room in the cylinder. The piston has a first magnetic member which magnetically drives a movable member with a second magnetic member connected thereto. The movable member moves along the cylinder. A cleaning unit is co-movably connected with the movable member. By expansion of the first expansion unit by the sun, the movable member is moved and the cleaning unit is moved along the glass surface. The action consumes no electric power. | 03-07-2013 |
