Compare Mowers
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.
Best suited for
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.
- Segway Navimow Navimow X420 — residential: typical home lawns; 17-inch deck; battery (no fuel or engine maintenance)
- Worx Landroid Vision AI 1/2 Acre — residential: typical home lawns; battery (no fuel or engine maintenance)
What’s different? The 4 differences that matter most, from the published figures.
- Navimow X420 is rated for slopes to 84%; Landroid Vision AI 1/2 Acre is rated for slopes to 30%, a 54 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; Landroid Vision AI 1/2 Acre ships with a 4 Ah battery, a 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.
- Navimow X420 cuts from 0.8 in (20 mm) to 3.7 in (95 mm); Landroid Vision AI 1/2 Acre cuts from 1.5 in (38 mm) to 3.5 in (89 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Navimow X420 is rated at 68 dB; Landroid Vision AI 1/2 Acre is rated at 59 dB, a 9 dB difference.
