Kress KR121E Mission 1000 OAS

The Kress KR121E Mission 1000 + OAS is a robotic mower designed for gardens up to 1,000m². It uses a boundary wire for navigation and features an Obstacle Avoidance System (OAS) to detect and avoid objects during mowing. It’s a good fit for smaller gardens with fixed features like trees or garden furniture.

About the Kress KR121E Mission 1000 + OAS

This model runs inside a perimeter wire and follows a consistent mowing path instead of moving at random. The Obstacle Avoidance System helps it steer around objects without stopping, reducing the chance of getting stuck or needing manual help. It’s well suited for homes with a lot of obstacles or complex layouts.

It comes with dual blades, a quiet electric motor, and automatic charging. The Kress app lets you manage zones, schedules, and mowing times from your phone. It’s designed for regular use and runs reliably with little day-to-day input.

Specific Uses for the KR121E

• Lawns up to 1,000m² with trees, play equipment, or other fixed features
• Gardens with wired boundaries already installed or planned
• Users who want better object detection in a standard wired system
• Split-zone or irregularly shaped lawns
• Quiet, low-maintenance mowing

Accessories You’ll Need for the KR121E

The KR121E blends reliable wire-guided mowing with real-time obstacle detection. To get set up quickly and keep it running smoothly, there are a few key accessories worth adding.

Perimeter Wire and Peg Kit

The mower requires a physical boundary wire for navigation. A standard wire and peg kit will be needed, and additional wire may be required for complex garden layouts or large borders.

Cable Repair Kit

Wire damage is common in active gardens. A repair kit allows quick fixes without replacing the entire line — ideal if the mower stops due to a break or cut.

Charging Dock Shelter

To extend the life of the charging dock, a small weather shelter is recommended. This protects against rain, debris, and long-term UV exposure, especially in open gardens.

Sensor Cleaning Kit and Spare Blades

Since the mower uses obstacle detection, keeping the sensors clean ensures consistent performance. A microfiber cloth or sensor-safe wipe is ideal. A set of spare blades is also helpful to keep the mower cutting cleanly throughout the season.
