AI summary of 5 reviews · as of May 2026
Reviewers agree the S8 Pro Ultra excels at mopping and navigation but offers incremental improvement over its predecessor at higher cost.

What they praise

- Outstanding navigation efficiency and fast mapping that completes floor plans in minutes with excellent coverage

- Excellent obstacle avoidance that rarely gets stuck except on stretched cords
What they knock
- Dual roller design tangles on stretched wires more frequently than camera-based predecessors

What owners single out
Buyers' weakest aspect—tangle resistance—directly overlaps the video reviewers' concern that the dual roller design tangles on stretched wires more frequently than predecessors.
In their words
“The only vacuum cleaner with a brain, and the only robot vacuum cleaner that actually does what it was designed to do to do. We bought and returned the other robot vacuum cleaner because they just zip in every direction, stupid and no why to know for sure everything was cleaned. Not only does RoboRock Vacuums clean in straight uniform lines they show you in the app. Pets? we have 3 dogs, they all ”

“I bought the Saros 10R for its zero tangle guarantee. I’m sad to report that after months of use this is just not true at all. I purchased the unit on June 4th 2025 and have been an almost daily user of the system. The rotating mops I love and it works amazing. It does keep my floors clean and mostly fur free except for shedding season when it will navigate around large clumps of hair: if you have”
