Patent number: 6571423Abstract: The invention relates to a surface-cleaning device (61, 63) which has a base part (69) and a cleaning part (67) having a substantially flat contact surface (71) for contact with a surface (41) to be cleaned and which is rotatable relative to the base part about an axis of rotation (77) extending substantially perpendicularly to the contact surface. According to the invention, the cleaning part is pivotable relative to the base part about a pivot axis (105) which extends transversely to the axis of rotation, and the base part is so constructed that a component (93) is present and exerts a pre-tension force, preferably a pre-tension torque (Mp) on the cleaning part about said pivot axis.Type: GrantFiled: August 23, 2000Date of Patent: June 3, 2003Assignee: Koninklijke Philips Electronics, N.V.Inventors: Henk Lijzenga, Benjamin Luurt Oudman

Patent number: 6574536Abstract: A moving robot first moves straight in a first forward path. When encountering an obstacle such as shelf, the robot makes a U-turn to move straight in a backward path located with a prescribed distance away from the first forward path. When encountering another obstacle, the robot again makes a U-turn to move straight in a second forward path extending in the same direction as that of the first forward path but located with a distance away from the backward path. When the robot exceeding the point of the U-turn in the first forward path is detected during running in the second forward path, presence of a region where the robot has not run yet is recognized, and running in that region is carried out thereafter.Type: GrantFiled: January 27, 1997Date of Patent: June 3, 2003Assignee: Minolta Co., Ltd.Inventors: Nobukazu Kawagoe, Yuichi Kawakami, Kyoko Nakamura, Yasuhisa Kinto

Patent number: 6571415Abstract: A self-propelled bare floor cleaner is provided having a random motion generator which enhances the maneuverability of the bare floor cleaner. The random motion generator is rotatably attached to the frame of the cleaner and propels the cleaner across the floor in a random motion. This random motion facilitates cleaning of the floor by making the cleaner easier to manipulate. The random motion generator includes a hollow spherical shell. In the preferred embodiment, the hollow spherical shell houses a weighted motor assembly which is rotatably mounted on a center fixed axle which extends diametrically between the first and second hemispherical halves and is attached thereto. The weighted motor assembly is comprised of a motor housing and a power source, such as batteries or cells. A motor is housed within the motor housing and rotates the motor housing about the center fixed axle.Type: GrantFiled: December 1, 2000Date of Patent: June 3, 2003Assignee: The Hoover CompanyInventors: Douglas E. Gerber, Kevin L. Thomas

Patent number: 6557207Abstract: A squeegee assembly of a floor surface treatment apparatus has an elongate frame member and a flange depending therefrom intermediate opposite ends of the frame member. A front squeegee blade, a spacer and a rear squeegee blade are arranged with the front squeegee blade nearer the flange than the rear squeegee blade and the spacer disposed intermediate the front and rear squeegee blades. A single clamping band abuts against the rear squeegee blade and has a quick-release mechanism selectively operable between an unclamped configuration and a clamped configuration in which the clamping band is releasably secured to the frame member and generally clamps the rear squeegee blade, the spacer and the front squeegee blade between the clamping band and the flange of the frame member. The rear blade extends lengthwise outward beyond the ends of the frame member.Type: GrantFiled: August 21, 2001Date of Patent: May 6, 2003Assignee: Alto U.S. Inc.Inventor: William R. Stuchlik

Publication number: 20030074752Abstract: To treat a surface by a device attracted to the surface by vacuum, it is necessary in most cases to guide a working device with a certain contact pressure over the surface. To be able to set the contact pressure of the working device with little effort, the device according to the invention rests at three points on the surface, one support point being formed by the working device. The force of attraction of the device against the surface is, therefore, accurately distributed to the working device and the other two supports so that the pressure force of the working device can be specifically varied and also controlled by varying the vacuum between the device and the surface.Type: ApplicationFiled: October 28, 2002Publication date: April 24, 2003Inventor: Jurgen Konrad

Publication number: 20030066148Abstract: A burnishing machine having a burnishing motor in a motor compartment covered with a hood defining an air plenum having at least one air inlet positioned near the top of the hood spaced from the floor. The plenum includes a discharge outlet immediately adjacent the motor such that clean air is drawn through the air inlet, flows through the plenum to the discharge outlet for providing clean air to cool the burnishing motor.Type: ApplicationFiled: September 19, 2002Publication date: April 10, 2003Inventors: Paul M. Pierce, Steven J. Waldhauser
