Roborock S8 Pro Ultra Review 2026 — The Most Autonomous Robot Vacuum?

How we tested

6-week test in a 110m² house (hardwood, tile, small rugs) with a dog. Scenarios: daily dust, pet hair, under-furniture zones, obstacles (cables, shoes), room transitions.

Navigation

The 360° LiDAR builds a precise map on the first run. In 45 minutes it had mapped 110m² accurately, including zones under sofas at 8cm clearance. The ReactiveAI 2.0 obstacle detection recognised cables, socks, and pet waste with 92% success in our tests.

Suction

6,000Pa — double the previous generation. On hardwood and tile, results are flawless. On long-pile carpet, the S8 Pro Ultra lifts fibres and extracts deeply embedded pet hair. The DuoRoller anti-tangle brush is a genuine advance: after a week with a dog, zero hair wrapped around the brush.

Mopping

The dual rotating mops apply 6N of pressure — sufficient for light stains and daily grime. Dried coffee or wine stains require multiple passes. Carpet lift detection automatically raises mops by 5mm, preventing rug saturation.

Ultra Station

The station's four functions eliminate nearly all human interaction:

• Auto-empties the dustbin (30-day capacity bag)
• Washes mop pads with hot water (55°C)
• Hot-air dries pads (2h) to prevent mould
• Auto-refills the clean water tank

In practice, we interacted with the robot about once a month to replace the dust bag.

Final verdict

The Roborock S8 Pro Ultra is the best robot on the market in 2026 for maximum autonomy. The Ultra Station justifies the premium over self-empty-only models. The only real barrier is the entry price — if it fits your budget, there is nothing better.
