  • Publication number: 20080029134
    Abstract: A motorized cleaning/polishing device includes a housing and a carrier with a detachable cleaning/polishing attachment. The housing contains a rechargeable battery, motor and flex mount having flexible pillars to which the carrier is mounted. The carrier is also coupled to the motor drive shaft via an eccentric element and bearing. The carrier may have a foam layer with hook fasteners adhered to its underside for removably attaching any one of various attachments to the carrier. Cleanser is impregnated in the attachment. The device is particularly suited to orbit in the 3000 to 10,000 OPM range.

  • Publication number: 20070192979
    Abstract: A visual indicator for the cleaning effectiveness and end of useful life of a cleaning implement, e.g., a fabric sweeper, for removing dust, dirt, pet hair and other debris present on a fabric surface. The implement comprises a housing and a pair of fabric-covered rollers. During a cleaning operation, the implement is swept over the surface to be cleaned. Debris is retained by the fabric on the rollers and transported to a collection chamber by the opposing roller. The fabric covering the rollers is a unidirectional fabric such as velour with a light color such as light blue. The light color provides an indication of cleaning effectiveness since the hair and debris loaded on the rollers contrasts with the light color and therefore can easily be quantified. The light color further aids in determining when the rollers have become too dirty such that the implement should be disposed and a new implement used.
