Vacuum-cleaner power-brush attachment

Abstract

A power-brush attachment usable in combination with a line-voltage source and with a vacuum-cleaner suction intake has a housing having a lower wall formed with an opening and a connection—suction tube and/or hose—on the housing engageable with the suction intake. The housing has a passage extending between the connection and the opening for drawing particles in the opening. A rotary brush in the housing is exposed in the opening and engageable therethrough with a floor underneath the housing. A low-voltage electric motor is connected to the brush for rotating same. A low-voltage power source, typically a battery, in the housing is also connectable to the motor for powering same without connection to the line-voltage same. A power converter and electrical line are connectable between the line-voltage source and the electric motor for powering the motor from the line-voltage source.
