Automower is the Electrolux second-generation battery-powered, automatic lawn mower driven by its "brain" computer. The cutting area is bordered by the "electrical outlet", ie ground limitation cables. The cables can be embedded in a few centimeters so that they have no disadvantages. In addition to these, a charging station requires the cutter to go when the battery starts to drain.
In addition to the timer, different cutting programs can be used. For example, the mower can be set with a cable function, whereby the cutter drives the cable to the end of the measured amount from the charging station and starts working only then.
