Abstract

A hand held vacuum cleaner unit and docking assembly for a central vacuum system is shown. The hand held vacuum cleaner has a handle, a suction nozzle, a trigger switch to turn on a battery powered suction motor and an outlet port. The docking assembly fits into a central vacuum cleaner mounting plate, and provides a cradle to store the hand held vacuum cleaner. Recharging contacts, a latch mechanism, seals and an intake port are provided on the docking assembly. When the hand held unit is in the docking assembly it may be electrically charged, and emptied of dirt and debris by activation of the central vacuum system. The docking assembly also includes an access port for a conventional central vacuum hose.
