Review: Roborock S8 Pro Ultra
The Roborock S8 Pro Ultra is the most complete robot vacuum system in 2026 — and the word “system” is key. It’s not just a robot: it’s an autonomous cleaning ecosystem. After each run, the dock automatically empties the dustbin, washes the mop pad with warm water, dries it to prevent mildew, and refills the onboard water tank. You interact with the physical robot perhaps once a month.
Suction Performance
6,000 Pa is at the top of the market. In our tests, it handled packed-in cat hair on medium-pile carpet, fine dust on hardwood, and cereal on tile without hesitation. The rubber dual-brush system resists tangling — a notable improvement over bristle brushes for pet hair households.
Mopping System
The VibraRise system vibrates at up to 3,000 RPM — actual scrubbing, not just dragging a wet cloth. On sealed hardwood, it removed dried coffee stains in a single pass. The auto-lift feature is crucial: the mop raises 5mm when it detects carpet, so you get vacuuming on rugs without leaving them damp.
Navigation & Obstacle Avoidance
PreciSense LiDAR maps rooms in a single pass. The RGB camera identifies and avoids cables, socks, and pet toys with roughly 90% accuracy in our tests — better than any prior Roborock model. Socks still get occasionally collected, but cables are reliably dodged.
Verdict
The S8 Pro Ultra earns its price premium for large homes or anyone who wants genuinely hands-free cleaning. If you vacuum 3+ times per week, the time saved pays back the investment within a year.
