Compact and affordable, the RX20U Automatic Robotic Lawnmower from Robomow is equipped with the latest features and specifically designed for smaller lawns up to 200m2 (maximum lawn size 300m2*). 

Automatic operation
Plan a cutting schedule on your mobile device (check device compatibility prior to purchase), and the RX20u will automatically depart the charging station, mow your lawn and return to it’s base to recharge on the time and days you’ve set. 

Efficient cutting
With a floating cutter deck, the solid 18cm stainless steel mulching blade on the RX20u perfectly follows the contours of any lawn giving an even finish across the whole lawn. Manoeuvring around the lawn, the twin wheel design ensures the blade can cut all the way to the edge of the lawn. Robomow effortlessly mulches grass cuttings into minuscule pieces; returning vital nutrients and water back into your lawn for a healthier, more beautiful lawn.

A short one-time setup is all that is required, and with Robomow installation kits with the required pegs and perimeter wire are included as standard. 

*Maximum Lawn Size – Under ideal mowing conditions; flat level lawn, simple rectangular shape, no obstacles or islands, no additional zones, no inactive time set and modest lawn growing pace.
