Navimow's new i2 AWD and X4/Terranox 4WD models have just been awarded the new standard in Turf-Safe mowing by Germany's TUV Rheinland. Navimow is the only robot mower range to have attained these new standards.
No other all-wheel-drive mower compares to Navimow when it comes to minimising damage to your lawn, and now we have independent third-party test results to prove it.
The i2 AWD only engages its third wheel when extra traction is required - for example, to prevent skidding. At at other times this wheel's rotation is free-wheeling to save energy. A separate motor turns the wheel left or right to rotate the mower in perfect synchronicity with the two front driving wheels.
The X4 and Terranox use Ackermann Steering to precisely turn each wheel the correct amount to prevent skidding and scuffing when turning in arcs. The inner wheel turns more tightly than the outside wheel (just like a car).
When engaging in zero-turn manoeuvres the two front wheels rotate to face each other at the correct angle for turning on the spot at the same time as the rear wheels counter-rotate. This is a very clever system indeed, pioneered by Segway for robot mowing, and we call it Xero-Turn.
Here in New Zealand we've heard plenty of complaints from owners of other brands of robot mower with 4WD systems. The common report is these mowers cause a lot of damage to lawns, and make a muddy mess - especially in winter. In particular, damage occurs all along the edges where mowers must make 180 degree turns as they mow back and forth across the lawn. Navimow's patented zero-turn technologies solve this problem.
As anyone who has ever watched a battle tank or drain digger turn can imagine, robot mowers fitted with tracks are even worse!
Last year our Navimow X3 range was awarded TUV Rheinland's certification for being the most efficient robot mower.
Our new H2 model is a 2WD mower with a pair of universal (caster) wheels supporting the front end, and a pair of driving wheels at the rear. Two wheel drive mowers do not cause significant turf damage when turning, and are a great choice for less demanding conditions.
Here is information from Segway's press release about this awards. Note that the specific X-series model used is the X420 that can mow 2,000 square meters. We don't sell the X420 model in New Zealand, rather we sell the X430 (3000 sq m) and X450 (5,000 sq m) configurations. All X-series models perform the same in these turf tests.

Segway Navimow X420 and i206 AWD models achieve the perfect balance between terrain capability and lawn protection: The TÜV Rheinland - certified Minimal Lawn Impact Performance.
BERLIN, April 14, 2026 /PRNewswire/ -- Segway Navimow, the pioneer in lawn care technology, has successfully subjected its X420 and i206 AWD robotic lawn mower models to rigorous testing by TÜV Rheinland. Both devices are the first and only to receive the coveted Lawn Care certification. This certification officially confirms that Navimow robotic lawn mowers deliver "Minimal Lawn Impact Performance," setting a new industry benchmark for ultimate lawn protection.
The technological backbone of this achievement is the advanced Xero-turn™ AWD system. This engineering innovation enables the mower to seamlessly navigate complex garden environments, effortlessly conquering steep slopes, stone paths, exposed tree roots, and conquer uneven terrain while minimising damage to the grass or turf. By ensuring stable, slip-free traction, the Xero-turn™ technology allows the device to glide over the grass with minimal friction, effectively safeguarding the turf from damage.
The certification is based on a comprehensive test catalogue that incorporates international standards as well as TÜV Rheinland's own benchmarks and certify the performance characteristics for maintaining a healthy and well-maintained lawn. As part of the intensive Accelerated Ageing Model a full calendar year of high-frequency mowing was simulated under European conditions. The results demonstrate:
- Minimal lawn impact: Both models achieved Level 2 of TÜV Rheinland's 5-level damage standard, meaning that after long-term operation, only minimal, localised traces remain, which do not affect the overall aesthetics and health of the lawn and are only visible upon close inspection.
- Ultimate terrain capability: Both X420 and i206 AWD successfully passed the steep slope tests while simultaneously recognizing and avoiding complex obstacles such as tables, chairs, and cables.

Industry leadership
- The X420 is the world's first four-wheel drive robotic mower to receive TÜV Rheinland "Lawn Care" certification.
- The i206 AWD is the only 3-wheel AWD robotic lawnmower on the market with this official certification.
Backed by rigorous TÜV Rheinland testing, this certification underscores Navimow's ability to strike the perfect balance between superior off-road capability and meticulous lawn care, even in the most demanding environments. For the user, this translates to a genuinely hassle-free experience. A certified "Lawn Care" mower guarantees reliable performance across challenging terrains, eliminating the frustration of the device getting stuck and requiring manual rescue. Furthermore, it ensures the lawn is never compromised by excessive wheel friction, allowing homeowners to enjoy a pristine, perfectly manicured garden with zero manual intervention.

The tests used an accelerated ageing model to simulate high-frequency residential usage scenarios for European users over a calendar year (calculated based on mowing twice a week for 10 months), with the environment including common obstacles such as tables, chairs, water pipes, electrical wires, and toys. The X420 operated normally at a slope of 57.7% (30°) and the i206 AWD at a slope of 47.6% (25°), achieving the "Minimum Lawn Impact Level." This level refers to TÜV Rheinland's Level 2 standard, meaning only extremely minor, localised traces (visible damage count ≤1), not affecting the overall aesthetics and health of the lawn, and only visible upon close inspection. Actual results may vary depending on lawn condition and environment.
