Here you can adjust the range of this lock by a switch different areas, with higher ranges course verbauchen even more power for the generation of the infrared beam.

Some lighthouses are turned on and off by hand, while others switch on automatically when the robot one (about the Roomba 782 ).

Lighthouses are signs that serve the robot as “signposts” in his journey through several rooms. They look just like the virtual walls, but have a slightly different function. Lighthouses have only makes sense if you want to clean more rooms, which are connected by open doors, in one fell swoop.

It is then to the respective connecting doors a lighthouse, which performs two functions:

    • on the one hand it prevents the robot vacuum cleaner from prematurely entering the next room when the current was not fully cleaned,


  • secondly, it helps in returning to the charging station, because the robot will find lighthouses may only by “scouring” of passed previously.
