Abstract

A vacuum cleaner includes several attachments and an attachment unit for accommodating the attachments. The attachment unit of the vacuum cleaner incorporates a crevice tool, an upholstery tool, or an upholstery brush. The attachments are connected to the attachment unit in a force fit and/or positive fit. The attachment unit, preferably, has a base body, to which the crevice tool and/or the upholstery tool and/or the upholstery brush is/are connected.

8. A vacuum cleaner, comprising:

a hose assembly;

a vacuum housing communicating with said hose assembly; and

an accessory unit removably connected to said hose assembly and having;

a base body; and

a plurality of accessory parts including a crevice nozzle and at least one of a furniture nozzle and a furniture brush, said accessory parts being connected in at least one of a force-fitting manner and a form-fitting manner to said base body, said crevice nozzle telescopically extending out of said base body.

9. An accessory unit, comprising:

a base body having an end side and a lateral wall; and

a plurality of accessory parts, including a furniture brush and at least one of a crevice nozzle and a furniture nozzle, said accessory parts being connected in at least one of a force-fitting manner and a form-fitting manner to said base body, said furniture brush having a sleeve enclosing said lateral wall of said base body in a circular manner and extending beyond said end side by rotation of said sleeve.

10. The accessory unit according to claim 9, wherein said furniture brush is disposed at said end side of said base body and is to be plugged, by said end side, one of onto and into a vacuum-cleaner tube component.

11. The accessory unit according to claim 9, wherein said accessory parts include a furniture nozzle disposed pivotally on an outside of said base body and pivoting from a rest position to an operating position.

12. The accessory unit according to claim 11, wherein:

said furniture nozzle has a furniture nozzle body defining two openings; and

said base body has an outside with two protuberances respectively communicating with said two openings to pivotally mount said furniture nozzle to said base body.

13. The accessory unit according to claim 11, wherein said furniture nozzle is arrested removably on said base body in at least one of an operating position and a rest position.

14. The accessory unit according to 13, wherein said furniture nozzle:

is of an elastic material; and
