The fully automatic robot vacuum cleaner Kärcher robot vacuum cleaners called RoboCleaner do all the work - without you lifting a finger: this machine cleans all standard household floor coverings. Even when you are not at home. Simply plug in the charging station, switch on, set the cleaning time and leave the rest to the RoboCleaner. It negotiates obstacles with ease. It even recognises stairs and steps. When its work is done, it automatically returns to base guided by an infrared beam. As well as recharging its batteries, it discharges the dirt it has picked up.
