Description

The Segway Navimow X390 (model X390N) is a wire-free robot mower for large lawns that positions itself by RTK from a GNSS antenna set up in the yard, fused with three cameras for visual mapping and a 3D time-of-flight sensor for obstacles.

Navimow rates it for lawns up to 2.5 acres and for slopes up to 50%, and its manual gives about 240 minutes of mowing a charge, with about 100 minutes to recharge. It cuts a 9.3 inch path from 2 to 4 inches high with electronic height adjustment, carries an IP66 rating and is rated at 60 dB(A).

It measures 27.5 x 21.7 x 12.1 inches and weighs 43.9 pounds, with rear-wheel drive and a dot-matrix status screen. Built-in 4G carries anti-theft tracking; renewal after the included period costs $32.90 a year.
