l claim:

1. ln combination with a Vacuum cleaner having a comparatively open elongate suction nozzle, a detachable brush comprising a pair of narrow brush bodies `adapted to be positioned one in front of the forward lip of the nozzle, and one to the rear of the rearward lip of the nozzle, a plurality of gripping members joining the two brush bodies, each such member comprising in monete part an arcuate spring portion adapted to penetrate the interior ofthe suction inlet, and to be compressed between the opposed walls of the inlet, and to direct a gripping pressure outwardly thereagainst, and means for preventing the rotation of said spring portions in relation to said brush bodies.

2. The combination with a vacuum cleaner casing having a narrow, laterallyl extended suction nozzle, of a brush, adapted to be secured to such nozzle, securing means therefor, comprising springs formed and adapted to penetrate the interior of the suction inlet, and to be compressed between the opposed walls of the inlet and to direct a gripping pressure outwardly thereagainst.
