  • Publication number: 20100064895
    Abstract: A device is provided that is capable of circulating air throughout a personal space as well as collecting and preventing the build up of dust and other particulate matter by drawing in air from the surrounding environment and removing some dust, allergens and other such particulate matter therefrom. The filtered air is then expelled out of the device and back into the surrounding environment. The device includes a housing defining an interior space having a motor and fan assembly disposed therein. The housing includes an inlet with a filter provided therein such that air drawn in through the inlet is filtered. The air is then expelled through a circumferentially disposed outlet. The filter element preferably includes a lock and key system configured to prevent operation of the device in the absence of a properly keyed filter.

  • Patent number: 7565712
    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: 20090048143
    Abstract: A cleaning composition for a hard surface is disclosed which provides for initial cleaning of the hard surface and provision of a hydrophilic coating or barrier layer on the surface which provides residual cleaning to the hard surface for an extended number of rinsings. The composition includes a hydrophilic polymer, at least one nonionic surfactant, at least one solvent, an acid and water, wherein the acid provides the composition with a pH of about 2 to 3.5 and the composition is provided in the absence of any anionic, cationic or amphoteric surfactant.

  • Patent number: 7001773
    Abstract: An artificial test soil is composed of particulate, hair, and fiber components, wherein the particulate component consists of mineral, food, and plant materials, so chosen and proportioned as to correlate to a typical soil found in the home. The test soil may be used to test cleaning products by application of a known amount thereof to a surface, cleaning the surface, and determination of the amount of soil removed from the surface.
