The RC312 Pro SX is ideal for lawns up to 1,200m2 offering a cutting width of 28cm (11”) as well as variable grass height from 15mm to 60mm. It can handle slopes of up to 36% (20o) thanks to its rugged extra wide power wheels.

The reversible steel tri-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.

Operation is extremely simple with the RC312 Pro SX having the capability to programme a weekly schedule so it leaves the charging station, mows and returns to recharge automatically.

On one full charge, the RC312 Pro SX will mow your grass in a random pattern for 60 to 70 minutes and then return to its recharging base before commencing mowing again. It will typically charge very quickly in about 70 to 90 minutes.

It is also equipped with a rain sensor so it can automatically delay mowing in rainy conditions. The sensitivity to rain can be adjusted to meet your needs. RC312 Pro SX includes a RoboHome which is a sheltered base station to protect it from adverse weather.

The RC312 Pro SX includes built in Bluetooth connectivity and can be managed on your smartphone with the Robomow android or iOS app. It also comes equipped with a GSM card to send operational and security alerts to your smartphone. This also sends technical data directly to Robomow’s support team to help diagnose faults.

Using your RX312 Pro SX 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.

It can also handle lawns of any shape as well as those split into more than one area using the ‘zones’ functionality. Up to 3 sub-zones and 2 separated zones can be accommodated.

The built in anti-theft system with tilt and lift sensors as well as a PIN code and alarm protects against the threat of having your robot lawn mower stolen.

It is also extremely cost effective using about 18kWh per month (about £2.77 per month).

Manufacturer’s Warranty is 2 years.
