The Kress KR251E EyePilot® RTKⁿ is a wire-free robotic lawn mower designed for residential lawns with a 24-hour mowing capacity of up to 1,000 m². It combines RTK satellite positioning with vision-based awareness to deliver stable, accurate navigation and consistent mowing performance without the need for a perimeter wire or added hardware.
About the Kress KR251E EyePilot® RTKⁿ
The KR251E is built for homeowners who want accurate, wire-free mowing on smaller lawns without the disruption of perimeter wire installation. It uses RTK-guided operation together with EyePilot® vision-based awareness to maintain precise movement across a range of garden layouts.
A redundant positioning architecture helps the mower maintain accuracy even when satellite signals are compromised, supporting stable navigation in shaded and more complex environments. This helps the KR251E work accurately across open lawn areas, tighter spaces, and more awkward garden shapes.
Wire-Free Mapping and Lawn Control
The KR251E operates without a perimeter wire. Lawn setup can be completed using automatic, assisted, or app-based mapping, giving flexibility depending on the layout of the garden and the level of input preferred during setup.
For gardens with more than one lawn section, the KR251E also supports multi-zone management with precise routing between lawn areas. Zones, settings, and system status are managed through the app, helping day-to-day control stay straightforward.
Navigation and Mowing Performance
The KR251E combines RTK satellite positioning with EyePilot® vision-based awareness to deliver stable, accurate navigation across garden environments. It supports both structured and random mowing paths, allowing the finish to be matched to the look of the lawn.
Structured mowing can be used for a more defined striped finish, while random mowing provides a more natural appearance. The mower is also designed to maintain consistent cutting performance in dense grass and stable navigation in shaded and complex environments.
Drive System and Terrain Suitability
The KR251E uses a rear-wheel drive system and is designed for stable movement across residential lawns, with a maximum slope rating of 40%. It is suited to gardens that need clean, consistent mowing and accurate routing between lawn areas.
For buyers comparing models within the wider EyePilot® range, lawn size, terrain, and layout should all be considered alongside drive configuration and feature set.
Quiet Operation and Day-to-Day Use
The KR251E operates at just 58 dB, helping it work quietly in the background without causing unnecessary disruption around the garden. Front lights provide added illumination in low-light conditions, supporting safe operation after dark.
The mower also includes intelligent obstacle awareness, helping it recognise and avoid objects that do not belong on the lawn. Software updates are delivered automatically, and location tracking allows the mower to be viewed if it is moved outside the property.
Specific Uses for the KR251E
- Residential lawns with up to 1,000 m² mowing capacity per 24 hours
- Gardens where perimeter wire installation is not wanted
- Lawns with multiple mowing zones and separate lawn sections
- Properties with shaded, narrow, or more complex garden layouts
- Users who want wire-free mowing with flexible mowing pattern options
FAQs
- Q: Does the KR251E require a perimeter wire?
