Kress Robotic Mowers Review (2026): Is Wire-Free RTK Still the Gold Standard?
For over a decade, robotic mowers came with a digital ball and chain: the boundary wire. But as we move further into 2026, the landscape has shifted entirely. Kress’s RTK-powered lineup, which once seemed like a futuristic promise, is now the benchmark for professional-grade residential lawn care.
This year, we revisited the Kress Mission series to see how the hardware and RTK network have matured. In a market now crowded with vision-based competitors, Kress continues to bet on centimeter-level satellite precision. We’ve pushed these units through another season of complex obstacles and shifting satellite constellations to see if they remain the king of the wire-free yard.
The RTK Edge in 2026
Standard GPS is a thing of the past for serious robotics. **RTK (Real-Time Kinematic)** remains the superior navigation method for 2026, offering reliability that cameras alone can’t match in low-light or high-glare conditions.
- How it Works: A stationary base station acts as a localized “anchor,” correcting satellite drift in real-time.
- 2026 Reliability: Improvements in multi-constellation support (GPS, GLONASS, Galileo, BeiDou) mean Kress units now maintain “Fix” status even under denser canopies than previous years.
- The Result: Consistent, professional stripes that look like they were cut by a human crew, every single time.
