Accessory assembly for vacuum cleaners
An accessory assembly for a vacuum cleaner comprises: an accessory body; a crevice attachment and an upholstery attachment, both formed integrally with the accessory body; and a dusting attachment disposed on the accessory body, the dusting attachment being slidably deployable to extend beyond the crevice attachment. Convenient cleaning can be achieved by selectively using the dusting attachment during the cleaning of a groove or narrow gap and deployment from one accessory attachment to another is easily accomplished without interruption of the cleaning process. The accessory assembly may be conveniently stored and used on an extension tube of the vacuum cleaner.
