Edge cleaning nozzle construction for suction cleaners

摘要

A suction cleaner nozzle has main and edge cleaning secondary nozzle openings oriented at right angles to one another. An auxiliary passage connects the secondary nozzle with a zone of high suction in the suction source for the main nozzle. Valve means in the auxiliary passage may be moved selectively to open or closed position. A clean-out door is provided for the auxiliary passage.
