Robot vacuums with mopping capabilities have been around for some time, typically using similar methods. The eufy S1 Pro, however, introduces a novel approach (after a record breaking run on Kickstarter, raising over $3.5 million in total.) Instead of using mopping pads that end up trapping dirt, the S1 Pro implements a rolling mopping brush that is continuously dosed with water to pick up dirt and deposit it into a dirty water tank.

As a mop, the S1 Pro is impressive, effectively removing stains that other robots struggle with. It also performs decently as a vacuum, though it struggles a bit with edges. Here’s our full review of the eufy S1 Pro.

Docking Station Design & Build Quality

In day to day use, the S1 Pro robot vacuum operates mostly autonomously, thanks to its very handy self-emptying and self-cleaning docking station.

eufy S1 Pro Vacuum and all-in-one Docking Station Review | TheEffect.Net As the roller rotates, it collects dirt, which is then dumped into the robot’s reservoir. This allows the S1 Pro to mop for extended periods without needing the roller cleaned, helping to stop dirt being dragged across the floor. However, some maintenance will be needed: the dirty water tank should be removed and rinsed weekly, and the debris tray should also be cleaned regularly. Despite this though, the S1 Pro is relatively low-maintenance. Its floor brush is designed to avoid hair tangling, with most hair collecting at the end of the roller for easy removal.This station itself features a clear 3-litre water tank, making it easy to see when refilling is needed and to watch the ozone creation process that sterilises the tank, ensuring the water on-board the vacuum is more hygienic when carrying out its mopping duties.

The docking station can also mix detergent automatically into the water tank, using 600ml bottles of eufy’s own Hard Floor Cleaner.

Dirty water is removed from the vacuum cleaner at the base of the station after roller cleaning, collected in a 2-litre tank at the rear of the station and, as mentioned previously, this should be cleaned to prevent any unwanted smells. The docking station also dries the roller with hot air, rotating it to ensure thorough drying. A spare roller is included, which is very handy, allowing you to clean one while using the other.

Dust is collected from the vacuum cleaner into a 2.5-litre bag on the station, which eufy claims can hold up to two month’s worth of dirt. The vacuum itself has a small bin with a filter that can be cleaned if clogged.

An LCD screen on top of the docking station provides maintenance alerts and instructions, making upkeep straightforward. Shortcut buttons on the robot and docking station allow for starting and stopping cleaning without needing the app also, if you’re stuck and need to send the robot back to the station but don’t have your phone on you.

Robot Vacuum Design & Build Quality

The eufy S1 Pro distinguishes itself with a mopping roller instead of the conventional microfibre pad. This roller spans nearly the entire width of the robot, offering extensive floor contact and a wide cleaning path.

As the roller rotates, it collects dirt, which is then dumped into the robot’s reservoir. This allows the S1 Pro to mop for extended periods without needing the roller cleaned, helping to stop dirt being dragged across the floor. However, some maintenance will be needed: the dirty water tank should be removed and rinsed weekly, and the debris tray should also be cleaned regularly.

Despite this though, the S1 Pro is relatively low-maintenance. Its floor brush is designed to avoid hair tangling, with most hair collecting at the end of the roller for easy removal.

The eufy S1 Pro’s 3D Matrix Eye system combines a camera, sensors, and AI to navigate and avoid obstacles such as shoes and cables. It impressively skirts around objects like pot plants while maintaining proximity to ensure a thorough clean. Although it’s useful to move some items for a deep clean, the S1 Pro can generally operate without much intervention.

Vacuuming Performance

With 8,000pa suction power, the S1 Pro ranks among the top in suction power. It automatically increases suction on carpets, efficiently picking up dirt and debris on both hard floors and carpets. Dual side brushes help clean edges, though corners may still require manual attention.

Mopping Performance

While we haven’t tested many other mopping robot vacuums, the S1 Pro did a fantastic job in our testing. It effectively removed various stains, including black coffee, strawberry jam, and clay from a potted plant which we dotted around our hard floor surface. The roller stayed clean throughout the session, maintaining consistent cleaning performance.

Notably, the S1 Pro eliminates the need for a traditional hard floor cleaner. It handled spills and tougher, dried-on stains pretty well without much issue. Saying that though, the roller doesn’t extend fully to the edges so you might need to do some manual cleaning with a cloth in those harder to reach places. The roller lifts 12mm off the ground to avoid wetting most short-pile carpets and rugs, a feature that works pretty effectively also.

eufy Clean App Functionality and Voice Assistants

The eufy Clean app (available on Android and iOS) is user-friendly. When setting the S1 Pro up for the first time, a short mapping run is needed, with the LiDAR system automatically (and quickly I might add) generating a map. Rooms can be split, merged, and named for convenience. The app supports virtual boundaries, no-go zones, and no-mop zones, useful for protecting delicate flooring or low furniture.

You can control cleaning from the app, selecting specific rooms or zones, and adjusting settings for vacuuming, mopping, suction power, and water usage. Voice commands via Alexa and Google Assistant allow for starting, stopping, and docking the robot which is surprisingly handy also.

Battery Life & Maintenance

The 4600mAh battery provides up to 170 minutes of runtime in standard mode. Even at higher settings, it covers a large area. The robot can return to the dock to recharge mid-clean if necessary and will go back to where it left off once it gets back to 65% charge, which is very clever. As mentioned previously, regular maintenance for both the vacuum and docking station includes weekly rinsing of the debris tray and dirty water tank.

The docking station’s debris tray should also be rinsed to prevent clogs, though the robot will alert you if this happens. Monthly maintenance also includes wiping the robot’s sensors and checking the brushes but, thankfully, the eufy Clean app provides reminders for these tasks.

Conclusion

Is the eufy S1 Pro worth your investment? If deep mopping of large hard floor areas is your priority, the S1 Pro is an excellent choice. Its roller and dirt removal system are highly effective on deep stains, and its self-cleaning capability during mopping sessions is impressive. However, if you need a combination of vacuuming, mopping, and edge performance, there may be better options available.
