RS 635 Pro SV
Overview
Reliable boundary-wire mowing for Up to 0.75 acres coverage
Full Review
The Robomow RS 635 Pro SV covers up to Up to 0.75 acres using Boundary Wire + Camera navigation with traditional boundary wire installation. It handles slopes up to 20° with its 2WD drive system and features a 22 in cutting width.
You'll need to install boundary wire around your mowing area before first use — plan for a few hours on smaller yards, or a full day for larger properties. Once installed, the system is reliable and the mower operates autonomously within the defined boundaries.
Key features include Camera obstacle detection, wide 22-in deck. At $2,500–$3,500, the RS 635 Pro SV competes in a crowded boundary-wire market where wire-free alternatives are increasingly compelling.
