Abstract
Description
[0001] The invention relates to a vacuum cleaner with an automatic pulling aid. The device has a pulling mechanism that, when the suction hose is moved, pulls the vacuum cleaner body along and assists it in rolling forward.
[0002] The pulling device can be implemented by a spring or roller mechanism that converts movements of the suction hose into a forward movement of the vacuum cleaner body.
[0003] Additionally, a safety device is provided that prevents the automatic advancement of the vacuum cleaner as soon as only a residual cable of between 40 cm and 60 cm remains on the cable reel, while further manual unwinding of the power cord is still possible.
[0004] The pull assist is integrated into the base of the housing and acts directly on the wheels of the vacuum cleaner.
Claims
[1] (Main claim): Vacuum cleaner with an automatic trailing aid, characterized by that the device has a pulling device which pulls the vacuum cleaner body along when the suction hose is moved and supports its rolling. [2] (Subclaim): Vacuum cleaner according to claim 1, characterized by , that the pulling device is actuated by a spring or roller mechanism, which converts movements of the suction hose into a forward movement of the vacuum cleaner body. [3] (Subclaim): Device according to any one of the preceding claims, characterized by that it includes a safety device which prevents the automatic advancement of the vacuum cleaner as soon as only a residual cable of between 40 cm and 60 cm remains on the cable drum, while further manual unwinding of the power cord over the cable drum remains possible. [4] (Subclaim): Vacuum cleaner according to any one of the preceding claims, characterized by, that the pull assist is integrated into the base of the housing and acts directly on the wheels of the vacuum cleaner.
