Definitions
- the invention relates to a vacuum cleaner robot.
- conventional vacuum cleaners are operated by a user who moves the vacuum cleaner and, in particular, moves the floor nozzle, through which dust is sucked, over the surface to be cleaned.
- conventional vacuum cleaner include a housing which is mounted on rollers and / or skids.
- a dust collector is arranged, in which a filter bag is located.
- a floor nozzle is connected to the dust collecting space via a suction pipe and a suction hose.
- an engine fan unit is arranged, which generates a negative pressure in the dust collector.
- the motor fan unit is thus arranged behind the floor nozzle, the suction pipe, the suction hose and the dust collecting container or the filter bag. Since such engine fan units are traversed by purified air, they are sometimes referred to as clean air engines ("clean air engine").
- dirty air or dirty air engine blowers are also referred to as "dirty air engine” or "direct air engine”.
- dirty-air engine or dirty air engine
- direct air engine The use of such dirty-air engines is also described in GB 554177, US 4,644,606, US 4,519,112, US 2002/0159897, US 5,573,369, US 2003/0202890 or US 6,171,054.
- Vacuum cleaner robots have also gained popularity in recent years.
