List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.

What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Husqvarna Automower 405X — residential: typical home lawns; 9-inch deck; battery (no fuel or engine maintenance)
- Segway Navimow Navimow i205 AWD — residential: typical home lawns; 7-inch deck; battery (no fuel or engine maintenance)
What’s different? The 5 differences that matter most, from the published figures.
- Automower 405X has a 8.7 in (220 mm) deck; Navimow i205 AWD has a 7.1 in (180 mm) deck, a 1.6 in 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 ›
- Automower 405X weighs 21 lbs (9.7 kg); Navimow i205 AWD weighs 27 lbs (12.1 kg), a 5 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Automower 405X's weight means for a trailer ›
- Automower 405X is rated for 0.15 acres (600 m²) of lawn; Navimow i205 AWD is rated for 0.12 acres (500 m²) of lawn, a 0.02 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 405X ships with a 2 Ah battery; Navimow i205 AWD ships with a 2.5 Ah battery, a 0.5 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.
- Automower 405X runs 50 min per charge; Navimow i205 AWD runs 60 min per charge, a 10 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
