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 550 is rated for 1.24 acres (5,000 m²) of lawn; Automower 305E NERA is rated for 0.22 acres (900 m²) of lawn, a 1.01 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Automower 550 runs 270 min per charge; Automower 305E NERA runs 50 min per charge, a 220 min difference. Stated run time is under the maker's conditions. Thick or wet grass shortens it.
- Automower 550 ships with a 10 Ah battery; Automower 305E NERA ships with a 2 Ah battery, a 8 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 550 is rated for slopes to 45%; Automower 305E NERA is rated for slopes to 30%, a 15 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Automower 550 charges in 60 min; Automower 305E NERA charges in 40 min, a 20 min difference. Charge time is with the supplied charger; another charger changes it.
