Back to recharge

The robot does not need the installation of an additional guide wire as common robots. When needing recharge, the robot detects the shortest way on the perimeter wire to the charging station. To avoid tracing the border by driving always on the wire, it can be programmed to proceed at a fixed distance alongside of it and match the wire betimes.

Blade safe stoppage

Border cut

Once in a while the robot proceeds to the cutting finish of the garden border along the perimeter wire. The border cut is a new feature which assures the pererct finish of your lawn .

Efficient cut

The combination of the robot working speed and its wide blade diameter assures a pefect management of sqm cut per hour increasing the cutting efficiency, optimizing cutting cycles and restricting the energy consumption.

Gyroscope

Intelligent spiral movement

Recognizing tall and thick grass, the robot triggers the intelligent spiral movement for a perfect finish and clearing of the area.

Li-ion technology

New state of the art technology based on high performing lithium batteries. The most modern solution to reach improved performance combined with longer working time

Light-weight

Small, compact and lightweight. The robot is suitable for small and medium gardens with narrow passages and high complexity. It easily tacles slopes and does not leave any trace on the ground.

Modular blade speed (1)

The blade speed modularity assures a perfect and homogeneous finish of the lawn cut by always keeping stable the rpm even when cutting in hard conditions - low battery recharge or on steep slopes for example.

Obstacle detection system on wheels

When the robot bumps into a tree or bush, the strain is perceived by wheels, the power to wheels is cut and this gives input to the robot to back up and continue its work on different direction.

Rain sensor

As cutting in dry weather produces the best result, the adjustable rain sensor alerts the robot to return to the charging station and stay there as long as it rains. It can optionally be paused, disabled or fine tuned to better match your local weather conditions.

Stainless steel blade

The best cutting performance. No comparison to standard robot cutters: the robot blade is made of stainless, robust steel requiring minimum maintenance.
