Abstract
A multi-purpose suction nozzle, for a vacuum cleaner, for cleaning different types of surfaces, such as hard smooth surfaces, textile floor coverings, and upholstery, whereby the suction nozzle is detachably connected to a suction hose of the vacuum cleaner via a pivotably mounted connector. The suction nozzle has a housing with a first suction opening that communicates with a first flow channel, and with a second suction opening about which are provided planar slide surfaces and which communicates with a second flow channel. A brush is rotatably mounted in the housing in such a way that bristles of the brush extend through the first suction opening. A mechanism provides for selective communication of either the first flow channel or the second flow channel with the connector.
