Eufy S1 Pro Robot Vacuums - Review and opinions

Key features

HydroJet Roller Mop

The roller mop is the defining feature here. It keeps itself refreshed while moving and presses down with 1 kg of force, which gives this robot a more active mopping style than the usual damp-pad combo.

That matters most in kitchens, entryways, and other hard-floor zones where light grime builds up every day. The practical upside is better floor feel and less streaking; the practical limit is that this is not the right tool for large liquid cleanup or deep stain rescue.

10-in-1 UniClean Station

The dock handles emptying, washing, refilling, drying, waste-water collection, detergent dispensing, and charging in one place. That is a big part of the S1 Pro experience, because the robot is meant to stay useful without constant hand service.

For a buyer, this means the convenience is real only if you are comfortable with a more involved base station. It reduces routine mess, but it also adds more components that need water, bags, and periodic attention.

Obstacle Avoidance and Square Body

The 3D MatrixEye system and square outline are aimed at better edge and corner coverage than a round robot usually delivers. That is a meaningful design choice for homes where dust collects along baseboards and under furniture feet.

The upside is cleaner paths around furniture and a better shot at reaching awkward spots. The trade-off is that edge cleaning still divides opinion, so this is not the robot to choose if your top priority is perfect wall-to-wall coverage in every room.

Battery and Capacity

The stated 216-minute battery life and 2.5-liter capacity give the S1 Pro enough room for longer cleaning sessions and less frequent emptying.

That helps the robot feel more complete in larger hard-floor homes, especially when paired with the self-emptying dock. The catch is that long runtime does not fix carpet limitations or make the maintenance burden disappear; it just gives the robot more endurance between dock visits.

User experience

If your daily cleanup is mostly crumbs, tracked-in dust, and kitchen film on hard floors, the S1 Pro makes sense as a home base robot rather than a quick novelty. The square body and obstacle avoidance are aimed at getting closer to edges and furniture than a round bot, and the mopping system is the real reason to look here. That matters because the roller-style mop is meant to keep cleaning itself while it works, which is a more serious approach than dragging a damp pad around the house. The upside is a cleaner floor with less streaking and less mop smear. The limit is that this is still a robot, so it is best at routine upkeep, not heavy spill recovery.

In a pet-heavy house, the appeal is the combination of strong suction, self-emptying, and a dock that keeps the mop side under control without constant hand washing. The confirmed 8,000 Pa suction and the recurring praise for pet hair pickup line up with the kind of daily mess that builds fast around dogs and cats. The practical win is less time spent clearing the bin and less hair wrapped around the cleaning path. The practical caution is that carpet is not where this machine looks strongest, so a mixed home with lots of rugs or deep carpet still pushes it out of its comfort zone.

The dock is where the convenience story either pays off or starts to feel like a chore of its own. Auto washing, auto refilling, hot-air drying, dirty-water collection, and detergent dispensing all reduce the number of manual touch points, but they also make the system more dependent on tanks, bags, and a proprietary cleaning routine. That is a good trade if you want a truly hands-off mop robot for a hard-floor home. It is a weaker fit if you want low-cost upkeep and minimal parts to think about, because the whole point of the S1 Pro is that it replaces some daily labor with a more complex station.
