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.
- Automower 320 NERA has a 9.4 in (240 mm) deck; Sunseeker X7 has a 14 in (356 mm) deck, a 4.6 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 320 NERA ships with a 5 Ah battery; Sunseeker X7 ships with a 10 Ah battery, a 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 320 NERA is rated for slopes to 50%; Sunseeker X7 is rated for slopes to 70%, a 20 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Automower 320 NERA is rated for 0.82 acres (3,300 m²) of lawn; Sunseeker X7 is rated for 0.75 acres (3,035 m²) of lawn, a 0.07 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 320 NERA weighs 29 lbs (13.2 kg); Sunseeker X7 weighs 32 lbs (14.3 kg), a 2 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Automower 320 NERA's weight means for a trailer ›
