A battery-powered washing unit is described which includes a motor drive unit driven by a DC battery pack with a yoke attached around the motor drive unit. An elongate and extendable handle is connected to the yoke for the user to grasp, and various brushes are connectable to the output shaft of the motor drive unit. Preferably the battery pack is sealed and self-contained and includes an integrated switch member at the top of the battery pack which consists of two powered positions, a low power and high power for various rotary speeds of the brush. Furthermore, the connection between the yoke and the motor drive unit consists of a locking mechanism having at least two locked positions, and a swivel position where the motor drive unit and the brush can swivel relative to the brush handle.

Air purifier

An air purifier, an air filter and a method of manufacturing an air filter for an air purifier are provided. The air purifier includes a base assembly, a filter assembly and a grill. A fan is mounted to the base assembly, and draws air through the filter assembly. The base and filter assemblies include adjoining walls having openings which are substantially smaller in area than the areas of the adjoining walls and area through which air is drawn in through the filter assembly. A resilient gasket having a passage approximately the size of these openings is positioned between the adjoining walls. The filter assembly is drawn towards the base assembly when the fan is operated, thereby enhancing the seal formed by the gasket against the adjoining walls. Unfiltered air is accordingly unlikely to bypass the filter assembly. The air filter is manufactured in an efficient manner through the use of a back plate having oblique end portions. A pleated HEPA filter is positioned in a U-shaped configuration and the ends thereof adhered to the oblique end portions. Top and bottom walls are then applied to the resulting structure.
