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’s different? The 5 differences that matter most, from the published figures.
- Navimow X420 has a 16.9 in (430 mm) deck; Navimow i208 AWD has a 7.1 in (180 mm) deck, a 9.8 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 ›
- Navimow X420 is rated for 0.49 acres (2,000 m²) of lawn; Navimow i208 AWD is rated for 0.20 acres (800 m²) of lawn, a 0.30 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Navimow X420 weighs 63 lbs (28.8 kg); Navimow i208 AWD weighs 27 lbs (12.3 kg), a 36 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Navimow X420's weight means for a trailer ›
- Navimow X420 is rated for slopes to 84%; Navimow i208 AWD is rated for slopes to 45%, a 39 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Navimow X420 ships with a 10 Ah battery; Navimow i208 AWD ships with a 5.1 Ah battery, a 4.9 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.
