If you’re looking for a high-end robot vacuum that can handle both vacuuming and mopping with minimal intervention, the eufy S1 Pro is an intriguing option. This model combines powerful suction with a unique real-time self-cleaning mopping system, making it especially useful for busy households. Eufy provided a sample of this vacuum for review, but all opinions expressed here are completely my own.
First Impressions and Unboxing
The eufy S1 Pro arrives in simple, well-organized packaging. Along with the robot and the UniClean self-cleaning station, the box includes an extra roller brush, side brushes, a replacement vacuum bag and filter, a power cord, a cleaning tool, and a hard floor cleaner. The setup feels straightforward, and everything you need to get started is included.
The UniClean station is particularly impressive. Both the clean and dirty water tanks are removable, making maintenance simple. Installing the cleaning solution is as easy as peeling a sticker and snapping it into place. The clean water tank also has a clear “Max fill” indicator, so you’ll never accidentally overfill it. At the base of the station, a removable cover hides the power cord and provides access to a micro USB port for troubleshooting. There’s even a clever access panel for clearing clogs in the self-emptying system, which is always a welcome design touch.
The robot itself is compact yet sturdy, with a square design that theoretically helps it reach corners better than most round vacuums. On top, multiple control buttons sit beneath a removable cover that includes maintenance tips and QR codes for app setup and customer support. The dust bin and water tank are easy to remove and reseal, and the mop system is both large and efficient, offering impressive coverage while cleaning itself in real time. The underside features spring-loaded drive wheels, multiple cliff sensors, a main mop, and color-coded side brushes that snap into place for easy maintenance.
Setup and App Experience
Once the robot is charged, setup through the eufyClean app is quick. The app provides a clear overview of previous cleaning runs, including coverage and cleaning time, and allows you to edit maps, set up virtual walls, and define no-go or no-mop zones. You can merge, divide, or rename rooms and choose from a variety of cleaning modes.
The app supports both vacuuming and vacuum-plus-mopping, though a mop-only mode is currently unavailable. You can adjust suction power, mop settings, and even set preferences for each room individually. Multi-level mapping allows the S1 Pro to remember different floors, and the app also includes scheduling, cleaning history, and manual controls to drive the robot remotely if desired. While it doesn’t have the advanced customization of some competing brands like Dreame or Roborock, it’s still detailed enough for most users.
Performance and Cleaning
In testing, the eufy S1 Pro handled a variety of household debris impressively. It picked up everything from dust, pet hair, and human hair to larger debris like Play-Doh, popcorn, glitter, and Christmas tree needles. The vacuum’s 8,000 Pa suction is powerful for its class and delivers excellent results on carpets, even in deep-cleaning tests where coffee grounds were embedded into fibers.

The mopping system, which cleans itself in real time, is the standout feature. Unlike many robot mops that require a return to the base station for cleaning, the S1 Pro continuously refreshes the mop pad with water and cleaning solution. While heavy spills may leave some staining, the mop is easy to rinse and maintain. The system also lifts the mop when it encounters carpets, preventing unwanted wetting of rugs or floor coverings.
Noise at maximum suction reaches 85 decibels, which is slightly louder than the average robot vacuum, but still acceptable for occasional deep cleans or when the unit is operating while you are away.
Battery life is excellent, offering up to 180 minutes of runtime at standard settings. Maximum suction will reduce this slightly, but the 4600 mAh battery still provides a solid runtime for most households.
Features and Design
The eufy S1 Pro has several features that set it apart. Its real-time self-cleaning mopping system is rare, making it ideal for households with high foot traffic or frequent spills. The square design helps with edge cleaning, though it could benefit from a mop extend feature to reach baseboards more effectively. The UniClean station simplifies maintenance by automatically dispensing cleaning solution and providing a self-emptying dust system.
While it lacks some features found in competing high-end models—such as hot water mop washing, dual roller brushes, LED lights, or a mop-only mode—the S1 Pro still offers strong suction, excellent carpet cleaning, and a well-designed app for scheduling and manual control. Its 3D Matrix Eye navigation system allows it to maneuver well in low-light environments, and the onboard camera can double as a home monitoring tool, allowing you to check on pets or family members remotely.
Final Thoughts
The eufy S1 Pro excels in mopping and vacuuming performance, particularly thanks to its real-time self-cleaning system. The station is user-friendly and visually appealing, and automatic solution dispensing is a thoughtful touch. While the app could offer more advanced customization, it covers all the basics and allows you to manage cleaning zones and schedules effectively.
For households that value convenience, performance, and innovative mopping technology, the Eufy S1 Pro is a compelling choice. Its combination of strong suction, real-time mop cleaning, and self-emptying functionality makes it one of the more advanced robot vacuums currently available. If you’re willing to invest in a premium model, the S1 Pro is likely to meet—and exceed—your expectations.
