- Owners’ ratings, 25%: none yet at the stores that ship to the United States, so this part is left out and the others count for more.

- Price does not count, so a discount never lifts a model. Only robots a lab has tested are ranked.

## The testers’ picks

- Vacuum Wars: Position 30 of 151 (list as of September 26, 2026), https://vacuumwars.com/vacuum-wars-best-robot-vacuums/

## Pros

- Among the best at spotting and steering around objects (Vacuum Wars, https://vacuumwars.com/roborock-s8-maxv-ultra-vs-dreame-x40-master-battle-of-the-plumbots/)
- Its mop pad reaches out along walls and under furniture (Vacuum Wars, https://vacuumwars.com/roborock-s8-maxv-ultra-vs-dreame-x40-master-battle-of-the-plumbots/)
- The dock hooks up to plumbing, so no water tanks to refill (Vacuum Wars, https://vacuumwars.com/roborock-s8-maxv-ultra-vs-dreame-x40-master-battle-of-the-plumbots/)

## Cons

- The long dock can stick out far from the wall (Vacuum Wars, https://vacuumwars.com/roborock-s8-maxv-ultra-vs-dreame-x40-master-battle-of-the-plumbots/)
- Connecting it to the plumbing takes some basic DIY skill (Vacuum Wars, https://vacuumwars.com/roborock-s8-maxv-ultra-vs-dreame-x40-master-battle-of-the-plumbots/)
- The app has no built-in voice assistant, unlike Roborock's (Vacuum Wars, https://vacuumwars.com/roborock-s8-maxv-ultra-vs-dreame-x40-master-battle-of-the-plumbots/)
