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").
  • Such dirty air or dirty air engine blowers are also referred to as "dirty air engine” or "direct air engine”.
  • the use of such dirty-air engines is also reflected in the documents GB 554 177 . US 4,644,606 . US 4,519,112 . US 2002/0159897 . US 5,573,369 . US 2003/0202890 or the US 6,171,054 described.
  • Vacuum cleaner robots have also gained popularity in recent years. Such vacuum cleaner robots no longer need to be guided by a user on the surface to be cleaned; they rather drive off the ground independently. Examples of such vacuum cleaner robots are for example from EP 2 741 483 , of the DE 10 2013 100 192 and the US 2007/0272463 known.
  • An alternative vacuum cleaner robot is used in the WO 02/074150 described.
