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 3 differences that matter most, from the published figures.
- Sunseeker X9 is rated for 3.00 acres (12,141 m²) of lawn; Sunseeker X9 Plus is rated for 6.00 acres (24,281 m²) of lawn, a 3.00 acres difference. The rated lawn area is the maker's figure under its own test conditions. Obstacles, slopes and complex shapes reduce it.
- Sunseeker X9 weighs 67 lbs (30.5 kg); Sunseeker X9 Plus weighs 72 lbs (32.7 kg), a 5 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Sunseeker X9's weight means for a trailer ›
- Sunseeker X9 is rated at 66 dB; Sunseeker X9 Plus is rated at 70 dB, a 4 dB difference.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
