The Rock Dock Ultra goes beyond standard self-cleaning by using hot water, drying cycles, and automatic detergent dispensing, making the S8 MaxV Ultra’s dock one of the most advanced and convenient in the category.

Owners appreciate the integrated cord wrap on the Rock Dock Ultra, which keeps the power cable tidy behind the base and minimizes dangling cords around the station.

With an extra-tall mop lift of around 20 mm, the S8 MaxV Ultra is one of the safest choices for homes with thick carpets, keeping rugs dry as it transitions between hard floors and soft surfaces.

The S8 MaxV Ultra’s remote-camera features are disabled by default and require both app approval and physical button presses on the robot to activate, and its onboard computer detects and avoids objects without sending photos to the cloud, offering stronger protection against unwanted video streaming than some competitors.

The S8 MaxV Ultra excels at pet-hair pickup, often leaving just a single dense clump of fur in carpet tests while other robots leave far more hair behind.
-
The S8 MaxV Ultra delivers strong hard-floor cleaning, typically leaving only faint traces of fine dust, though recent tests show it lagging slightly behind models that completely clear test patches.
-
Overall, reviewers see the S8 MaxV Ultra as a highly capable but extremely expensive flagship whose great navigation, mop lifting, and smart features helped it achieve the top feature score and second place overall in 2024 tests, yet sticky mopping, hair-wrap issues, and weak value compared with cheaper rivals still hold it back.

Obstacle avoidance is good but not flawless: the S8 MaxV Ultra reliably goes around larger objects like boxes and candles but still bumps small items such as remotes often enough to land in the upper-middle of avoidance rankings.
-
On low-pile carpets the S8 MaxV Ultra delivers above-average pickup and usually lands near the top of test groups, but it still trails the very best deep-cleaners like the L10s Ultra and older S7 MaxV in raw carpet extraction.
