Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Roborock - S8 Pro Ultra | Wyze - Robot Vacuum Pro |
|---|---|---|
| Suction | 6000 Pa | 3000 Pa |
| Battery life | 180 min | 120 min |
| Noise | 67 dB | 65 dB |
| AI obstacle avoidance | true | false |
Between the S8 Pro Ultra and Robot Vacuum Pro, the S8 Pro Ultra comes out ahead in suction / battery life, while the Robot Vacuum Pro wins on noise. Overall, the S8 Pro Ultra scores 79 and the Robot Vacuum Pro scores 74.1 on our Mars Score.
Which should you buy?
The S8 Pro Ultra edges ahead on the Mars Score (79 vs 74.1), but the 4.9-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the S8 Pro Ultra if you care most about suction / battery life. The biggest gaps in its favor are suction, battery life, ai obstacle avoidance. The single most decisive one: Suction — 100.00% more. 6000 Pa vs 3000 Pa.
Pick the Robot Vacuum Pro if you care most about noise. Its strongest claims are noise. The single most decisive one: Noise — 2.00 dB less. 65 vs 67.
Both ship with comparable mopping, lidar, self-empty base, so those specs do not separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
Which should you buy: Roborock - S8 Pro Ultra or Wyze - Robot Vacuum Pro?
Roborock - S8 Pro Ultra leads the current Mars Score by 4.9 points.The more useful decision is the trade-off behind that result: compare suction, battery life against the way you will actually use the product.
