Blade time + recharge breaks for one full cut, by lawn size · at the quality speed (2 ft/s)
Robot mowers cut little-and-often, so a full cut rarely happens in one sitting — your weekly schedule splits this across mow days automatically.
On a customer install in Bucks County, Pennsylvania, a single X430 works a man-made berm whose steepest faces pass a 40% grade — climbing, descending and side-hilling between dozens of newly planted trees and shrubs, mapped as multiple zones off a local RTK base station. That's inside the 84% rating with room to spare, but a slope rating assumes traction: wet grass, thin turf and what sits at the bottom of the hill still get assessed zone by zone, which is exactly what a professional install is for.
