Kress Kress RTKⁿ 28,000 m² robotic lawn mower with OAS (Obstacle Avoidance System)

The Kress RTKⁿ KR235E targets very large areas up to 28,000 m², with a high-power motor paired with a sliding disc built for efficient, precise cutting even on short, dense grass. Weight 23 kg, 35 cm cutting width, an especially low height range of 20-40 mm, 40% max slope.

That minimal cutting height marks it out for paths and short-grass zones rather than a typical residential lawn, with speed and consistency tuned for that kind of intensive use. Like the rest of the RTKⁿ range, it navigates without a perimeter wire — a satellite antenna marks out a virtual mowing boundary in the app, well suited to large properties where a wired install would be impractical. OAS detects fixed obstacles along the route to adjust course.

Battery recharges in about 30 minutes only — noticeably faster than the KR233E, in line with semi-professional use with rapid turnaround. A robotic lawn mower for extensive properties needing a short, uniform cut.
