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.

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.
- Kress Kress RTKⁿ ½-acre robotic lawn mower — residential: typical home lawns; 8-inch deck; battery (no fuel or engine maintenance)
- Sunseeker Sunseeker X5 — residential: typical home lawns; 9-inch deck; battery (no fuel or engine maintenance)
What’s different? The 4 differences that matter most, from the published figures.
- Kress RTKⁿ ½-acre robotic lawn mower is rated for slopes to 40%; Sunseeker X5 is rated for slopes to 60%, a 20 points difference. The slope rating is the maker's limit for safe operation, not a measure of performance.
- Kress RTKⁿ ½-acre robotic lawn mower ships with a 4 Ah battery; Sunseeker X5 ships with a 5 Ah battery, a 1 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.
- Kress RTKⁿ ½-acre robotic lawn mower has a 7.9 in (200 mm) deck; Sunseeker X5 has a 8.7 in (221 mm) deck, a 0.8 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 ›
- Kress RTKⁿ ½-acre robotic lawn mower cuts from 1.6 in (40 mm) to 3.5 in (90 mm); Sunseeker X5 cuts from 1.6 in (41 mm) to 3.2 in (81 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
