Our Verdict: Smart features at a budget price. iRadar obstacle detection is a nice upgrade over basic bump sensors.
The Yard Force Compact 400Ri adds smart features to the budget category with iRadar ultrasonic obstacle detection and smartphone app control, features typically reserved for more expensive mowers.
Covering up to 400m², it’s designed for small suburban lawns where affordability and basic smart features are the priority. The ultrasonic sensors detect objects before impact, reducing collisions.
