Robomow RX20 7 in. 4.3 Ah Lithium-Ion Robotic Lawn Mower (Up to 1/20 Acre)

The Robomow RX20 Robotic Lawn Mower is ideal for small lawns up to 1/20 acre (200sq.m). Contained within the lawn by installing a perimeter wire, the RX20 leaves its charging station once a day and randomly mows within the perimeter wire for around 3 hours. It then returns to recharge (8-10 hours) and go back out to mow again the next day. With a maximum cut h8 of 1.75 in., the Robomow RX20 maintains an "always mowed" appearance without any effort from the homeowner.
