Abstract
Abstract An attachment is provided for a vacuum cleaner hose and is equipped with a canister having a handle and a nozzle having a pointed suction head. Within the nozzle a vacuum plenum is bounded by a partition having an array of firm pliable fingers about its perimeter and a plurality of flexible annular tubes within the perimeter thereof and in communication with the plenum. An exhaust pipe extends rearwardly from the attachment and is connected to a household vacuum cleaner hose. The nozzle is worked across the coat of a house pet, such as a dog or cat, to rid the animal of fleas. Within the canister there is a disposable tubular bag which contains a chemical substance that kills fleas and flea eggs as they are dislodged and carried by suction from the animals coat.
