What’s different? The 5 differences that matter most, from the published figures.
- X350A Robotic Lawn Mower has a 237 mm (9.3 in) deck; Navimow X450 has a 430 mm (16.9 in) deck, a 193 mm difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- X350A Robotic Lawn Mower is rated for slopes to 50%; Navimow X450 is rated for slopes to 84%, a 34 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- X350A Robotic Lawn Mower weighs 19.8 kg (44 lbs); Navimow X450 weighs 29.2 kg (64 lbs), a 9.4 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What X350A Robotic Lawn Mower's weight means for a trailer ›
- X350A Robotic Lawn Mower ships with a 10.4 Ah battery; Navimow X450 ships with a 15 Ah battery, a 4.6 Ah difference. Amp-hours is stored energy at the pack's voltage. Run time also depends on load, so a bigger pack lasts longer under the same conditions, not a fixed time.
- X350A Robotic Lawn Mower runs 180 min per charge; Navimow X450 runs 130 min per charge, a 50 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
