The RX20u is compact, precise, clever and easy to use robot lawn mower ideal for small to medium sized gardens up to 200m2 in size although 300m2 can be accommodated if the lawn is flat, level, simple rectangle with no obstacles or additional zones. A perfectly manicured lawn can be achieved in just 1 hour 30 minutes.

Using your RX20u is extremely simple to set-up and use. A short one-time setup is all that is required to connect the base-station and lay the perimeter cable.  Typically the perimeter wire will be covered by grass and become unnoticeable in a matter of 2-3 weeks.

While the RX12u runs on a ‘Press To Go’ system, the RX20u has a programmable weekly schedule so it leaves the charging station, mows and returns to recharge automatically.

Built to accommodate changes in ground level and slopes up to 15% using its robust wheels and floating cutterdeck. This robotic mower has a cutting width of 18cm (7”) and an adjustable cutting height from 15 to 45mm. It also has an edging functionality.

The RX20u includes built in Bluetooth connectivity and can be managed on your smartphone with the Robomow android or iOS app. It can also be equipped with a GSM card to send operational and security alerts  to your smartphone. It can also send technical data and diagnose faults by communicating directly with Robomow’s support team.

The rugged steel blade can cope with high grass, apples, bread and even twigs whilst the patented ‘Grasscycling’ technology cuts the grass into mulch that fall into the grass roots, where it decomposes and acts as a natural fertilizer. Mulching helps to improve the quality of your lawn by recycling nutrients, reducing moisture loss and suppressing weeds.

The built in anti-theft system with PIN code protects against the threat of having your robot lawn mower stolen.

It is also extremely cost effective using about 4kWh per month (about 62p per month).

RX models are fitted with a European power supply plug with a UK adaptor. This is for use in a dry location i.e. indoors or in a suitably sized weatherproof box (IP55 higher)/outdoor power socket.

Manufacturer’s Warranty is 2 years.
