An electrical appliance in which a motor-driven roller is rotated, the roller being fitted with any type sleeve designed for a specific task such as washing a window glass, sanding a car body or buffing a surface of an object.

A two-constituent combination of phosphoric and nitric acids with a minimal volume of water. The composition is designed to remove stains, corrosion, dirt and encrustations from coinage metals composed mainly of copper, silver, brass, bronze and gold. No abrading action is required and there are no adverse effects on the substrate.

A fuel adsorption member 16 is fixed to an inner surface of a housing 13 by fixing pins 14. A fuel vapor leaking from an intake system of an engine is adsorbed by an active carbon included in an adsorption sheet member of the fuel adsorption member 16. The fuel adsorption member 16 is arranged along an inner surface of the housing 13. Accordingly, when an engine is operated, the fuel adsorption member 16 can reduce a ventilation resistance without being adversely affecting an intake air E. Furth...

A vacuum cleaner having a suction path at least partially submerged in a container of water is subdivided into two parts. An upper part supports a suction motor assembly, and a lower part includes a container of water engaged perimetrically by hooking means to the upper part, and a tubular jacket inside the container partially immersed in the water, so that an annular interspace is formed between respective side facing walls. The interspace forms a siphon to allow suction motor means to draw air...

A vacuum cleaner with an external surface incorporates a cyclonic separating apparatus that includes a plurality of cyclones arranged in parallel with one another. The cyclones each have a tapered body with an outside wall and are arranged so that at least a part of each outside wall forms part of the external surface of the vacuum cleaner.

An improved dental prophylaxis device for cleansing the teeth of a user and massaging the gums of the user of a type having a pair of absorbent core members that are convexo-concave-shaped and have convex surfaces and which are saturated with dental cleansing material and which are flexible but capable of retaining their shape and which are enclosed in a spaced-apart disposition within a saturable covering layer that has a longitudinal center line and a variegated surface and a portion between t...

Disclosed is a vacuum cleaner which can remove sludge, bad smells and toxic gases and discharge the filtered air to the upper portion of the vacuum cleaner to prevent the filtered air from being sucked with non-filtered air into the cleaner again. The vacuum cleaner includes: a dust collector having a suction hole; a cleaner body sealably assembled on the upper portion of the dust collector; a handle hinged on the upper portion of the cleaner body; a filter assembly assembled inside the dust col...

The cleaner includes a long pole having a mirror adjacent its upper end for inspection of the gutter from the ground without using a ladder. A gutter-clearing tool above the mirror has a downwardly angled arm provided with a lower working tip that may be in the nature of a scoop. The arm may comprise a two-part construction having an inner work component in the form of a pick for removing downspout clogs and an outer component in the nature of a scoop so that the cleaner can either be used with ...

A vacuum cleaner includes a dust-collecting chamber that is separated from the vacuum cleaner's motor chamber by a partition. The dust-collecting chamber is provided with disposable and reusable filters that separate and collect dusts and dirt from the air that is drawn into the dust-collecting chamber through an air inflow hole in the partition. The filters are supported by fixing guides disposed at sidewalls of an air inflow hole of the dust-collecting chamber.

An air cleaner for cleaning air and for providing sterilization and deodorization effects, includes an air-liquid contact part, for bringing the air into contact with a water screen formed by spraying, using nozzles, pressurized circulating water, and for removing foreign materials from the air; a liquid separating part for separating from the air, tiny water droplets that are included in the air passing through the air-liquid contact part; a cylindrical body into which air to be cleaned is guid...
