The Robomow RS635 Pro SX with power wheels & heavy duty brushless motor is designed for lawns up to 3600m2 and can be programmed to start & stop mowing when you prefer through a smartphone & Bluetooth. The RS635 Pro SX uses twin-edged reversible tri-blades which mulch the grass into tiny pieces which virtually disappear into the lawn for a superb best cut and finish. 

The Robomow RS range of automatic lawn mowers have floating cutting decks and a 56cm mowing width with 2 tri-edged cutter blades. The floating decks are counter balanced which allows the mower to follow the contours of the lawn for an even cut and finish.

The RS635 Pro SX is powered by a 26v 6Ah Lithium battery which is automatically charged each time the mower returns to the base station. The improved LiFePO4 battery has a faster charging time, longer battery life and is more environmentally friendly than previous lithium batteries.

Attached to a base station the Robomow RS635 Pro SX robotic mower leaves the base at an appointed time and will return there at the end of the mowing run to re-charge ready for the next cut.

The Robomow RS635 Pro SX has excellent features including

  • A ‘planetary’ gearbox is compact in design with sealed bearings which help to reduce the overall noise level of the mower.
  • A rain sensor so the mower stops cutting in the wet and returns directly to its base going out again only when the conditions improve.
  • Smartmow so the mower plans its next move before reaching the perimeter wire, full multi-zone support and access to a mobile app for installation help and customer service advice.
  • The tilt sensor stops the cutter blades rotating if the mower tilts too far over or is picked up.
  • An anti-slip sensor allows the mower to react quickly if it gets stuck and reduce the chance of it loosing traction.
  • The anti-theft protection, PIN code disabling system and an alarm system are standard for extra peace of mind.
  • The Robomow RS635 Pro SX can drive itself to the next mowing zone even if this means crossing a path or terrace. The mower comes complete with base station, power wheels, Robohome, an Operating Manual, DVD, Quick Start Guide, 400 metres of perimeter wire and 500 pegs.
