The RC304u is ideal for lawns up to 500m2 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 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 RC304u 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 RC304u will mow your grass in a random pattern for 45 to 50 minutes and then return to its recharging base before commencing mowing again. It will typically charge very quickly in about 50 to 70 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.

The RC304u 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.

Using your RX304u 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 11kWh per month (about £1.70 per month).

Manufacturer’s Warranty is 2 years.
