The RX model from Robomow makes automatic mowing more accessible than ever before.

Custom Scenes


Completes a given lawn faster than competing robomowers, designed for similar sized lawns.


Unique Edge mode and 'cut-beyond-the-wheel' design for that extra special Robomow finish.


Easy-to-use with flexible installation options and full control from your smartphone!


Prevents faults and minimizes downtime by collecting technical data from your Robomow. Gives you operational and security alerts directly to your smartphone!


70% wider wheel for better maneuverability (included on RC308 and RC312. Available as an accessory for the RC304)


Keeps both your mower and prying little fingers safe and sound. Personalized PIN code ensures that others can't operate your Robomow without your consent or knowledge.


Sensational mowing speed for longer time thanks to Robomow's long-lasting Lithium-Ferrum high performance batteries


Programmed to protect itself from rain, Robomow returns independently to its Base Station in rainy weather, and departs again only when conditions are better. Rain sensor sensitivity can be adjusted.


Drives independently to different zones in your garden (connected by a pathway or a strip of grass) and returns after completing each zone.


Never lose a blade again! Robomow's blades are extra solid, super secure, ensuring maximum performance and mowing safety. Replacement is required only once a year.


Handles extraordinarily high grass, with ease. TurboMow automatically switches off when desired grass height is reached.


Never miss a mow! Designed for quick and intuitive parts replacement - most parts can be easily changed by the user to minimize downtime in peak season.


Operate and communicate with your Robomow through your mobile phone or tablet.


Robomow blade stops rotating immedialtey if it is lifted from the ground or tilted to a vertical position. When the bumper senses an obstacle, blades stop and Robomow changes its driving direction. To prevent children from operating Robomow, activate the Child Lock.


This is a safety feature to help prevent children or others not familiar with the safe operation of Robomow from operating it freely.


Robomow can mow areas imside the working area with slopes of up to 36 percent


Robomow's cutting height can be adjusted to your lawn's needs


Although Robomow is very powerful, it is also very quiet and allows to enjoy your lawn even when Robomow is mowing.


Use ECO (Economic) option to operate Robomow with the minimum energy needed for cutting the grass and maintaining the lawn.

Note: RX models are fitted with a European power supply plug with UK adaptor. This is for use in a dry location; indoors or in a suitable size weatherproof box (IP55 higher) / outdoor power socket.
