With a maximum mowing area of 24,000m² (roughly 6 acres), this machine is ideal for sports fields, golf courses, municipal green spaces, and corporate campuses looking for consistent and efficient results while minimising manual labour and operational costs.
Effortless Wireless Installation & Precision Navigation
Unlike many commercial robotic mowers, the Navimow CM120M1 does not require boundary wires or external antennas for installation*. Its technologically advanced EFLS™ NRTK navigation system (incorporating NRTK, 360° Vision, and VIO) enables precise mapping, positioning, and route planning. Setup is streamlined, helping reduce installation time and ongoing maintenance complexity.
Advanced All-Terrain Capability
The all-wheel-drive (AWD) system, combined with a robust chassis, allows the CM120M1 to confidently tackle slopes up to 40° (84%), guaranteeing dependable mowing even on undulating or uneven terrain. The mower’s 17″ cutting width and adjustable height (0.75–4 in) further enhance productivity and adaptability to diverse grass conditions.
Clean, Consistent Cutting & Quiet Operation
Dual deck design, dual motors, and twelve high-performance blades deliver a uniform, high-quality finish across all grass types. Operating at just 68 dB(A), the Navimow CM120M1 is suitable for use during evening or night-time hours in noise-sensitive environments.
Fleet Management & Operational Oversight
For sites managing multiple mowers, the NavimowFleet™ solution lets operators oversee large fleets from a single app or web portal. Tasks such as mapping, assignment, and performance tracking can be managed remotely, making this mower especially advantageous for contractors or organisations with expansive grounds to maintain.
