After analyzing over 70 verified owner reviews and expert tests, the eufy Omni S1 Pro stands out as the best robot vacuum for hard floor mopping—but it’s not for everyone. Owners consistently praise its revolutionary roller mop system that actually removes dried stains (not just pushes dirt around), while experts at Vacuum Wars confirm it outperformed competitors on coffee and grape juice stains. However, if you have mostly carpeted floors, this $999-$1,500 robot struggles with thick pile carpets and scores below average on deep carpet cleaning.
What Real Owners Say About the Eufy S1 Pro
The eufy Omni S1 Pro earns overwhelmingly positive reviews from actual owners, with the majority rating it 5 stars after months of daily use. One verified purchaser who waited six months before reviewing wrote: “I love this thing, worth every Penny…my floors are just always clean now with very little effort from me.” This sentiment appears repeatedly across dozens of reviews.
BrianD, an engineer who tested multiple robot vacuums over the years including Neatos, Roborocks, and Dreames, called the S1 Pro “by far the best I’ve used.” He noted that previous models would pack the dust bin with pet hair so tightly “it’s like felt—and the base can’t empty that.” The S1 Pro solved this by allowing users to adjust how often it returns to empty, which he set to the lowest setting for his two heavy-shedding dogs.
Jake, who’s owned the S1 Pro for 5-6 months, describes it as “legitimately kinda life-changing” despite noting some flaws. His household includes kids and a dog on mostly hard flooring (LVP and hardwood). He explains: “Keeping the floors free of debris and looking clean required vacuuming every couple days and mopping at least once per week. The mopping, in particular, is awful…This robot ended that headache for good.”
Yaniv evaluated three different high-end robots in his home—the Dreame X40 Ultra, the Eufy S1 Pro, and the Ecovacs X5 Pro Omni. He ultimately kept the Eufy, stating: “After having seen all 3 robots in action, I think the Eufy S1 Pro stands out big time on most features, including its mopping, cleaning efficiency, obstacle avoidance, and navigation.”
Roller Mop Technology: A Game-Changer for Hard Floors
The eufy S1 Pro’s standout feature is its unique roller mop system, which fundamentally differs from the dual rotating pads found on competing robots. According to Vacuum Wars testing, this roller system with 1 kg of downward pressure proved “far more effective at deep stains” than traditional mop pads, successfully removing dried-on coffee and grape juice stains that other robots merely smeared.
Multiple owners specifically mention how the S1 Pro handles mopping compared to their previous robots. BrianD compared it directly to his Dreame L20: “My Dreame just smeared the dirt around…Always left little muddy round tracks on the floor. The water tanks are much smaller than the Dreame, probably 1/3-1/2 the size. But it uses so much less water that it’s not an issue.”
The roller mop continuously self-cleans during operation, with dirty water extracted via a squeegee into an onboard dirty water tank. This design allows the robot to handle wet stains better than competitors. As Yaniv noted: “Unlike the upright mop, the robot separates between the dirty water tank (which is basically the dirty water continuously being extracted from the roller using a squeegee), and the vacuum, which has its own dust bin…So no suction of fluids, but still better at mopping wet stains than any of the other robots out there.”
One owner even tested it on cat vomit on hardwood floors and reported: “It worked perfectly and didn’t smear, or spread it anywhere else!” While this isn’t the robot’s intended use case, it demonstrates the roller system’s ability to contain messes rather than spread them.
The only consistent mopping complaint is edge coverage. The roller doesn’t extend all the way to walls, leaving approximately 1.5 inches uncleaned along baseboards. Jake notes: “It doesn’t get all the way up to the edge of the room. The only place I notice it is near the dishwasher, where some crumbs and things of that nature are missed.”
Navigation and Obstacle Avoidance Performance
The S1 Pro uses internal LiDAR combined with active binocular infrared imaging for navigation and obstacle avoidance, and owners consistently praise its intelligence. Kunani, who has three cats and cat toys constantly scattered around, wrote: “Past robot vacs we bought would always have toys stuck in them. This one actually sees anything and goes right around it without problems.”
Yaniv highlighted navigation as a critical test in his home, where the base station sits cornered by a large dining table with 12 chairs. His Dreame X40 Ultra “was constantly getting confused by the table and chair legs, pausing for long periods of time.” In contrast, the S1 Pro “navigates its way around, and next to almost everything, and just finds ways to continue the cleaning path without getting confused.”
The robot creates detailed maps autonomously and shows real-time location tracking in the app. As Maui John describes: “The robot ‘discovered’ the entire flooring on its own and created a line drawn map. The robot shows you where it is on the map in real time…If it had to avoid any cords or shoes it puts a little icon on the map to show you its exact path.”
BrianD noted the cleaning path efficiency: “My Dream left little trails of dirt at every threshold and transition to a carpet—this doesn’t. And it doesn’t leave little piles when it starts climbing the ramp on the dock.” He also praised edge cleaning: “Since the unit is more squared off, the brushes are mounted towards the corners and extend out well past the body of the unit…Most of the round ones stick out past the diameter—but since they are towards the front of the unit, they don’t really get past the OD path at the widest part.”
The S1 Pro reliably docks itself when finished. BrianD compared this to his previous Dreame: “[It] would very rarely dock properly—it would try to climb the ramp to dock and the wheels would spin, causing the vacuum to get tilted and miss the docking/charging ports…The Eufy has been perfect—vacuumed/mopped exactly where the mapping says it should, has never NOT completed a cycle and docks perfectly.”
Maintenance and Base Station Features
The Uniclean base station automates nearly all maintenance tasks: emptying the dust bin, washing and drying the mop roller, refilling clean water, and storing dirty water. It even includes an ozone generator to keep water fresh. Multiple owners praise how little hands-on maintenance the system requires.
Dawn, who waited six months to review, reports: “I’ve only taken it apart once or twice and cleaned the dirty water reservoir within the actual robot, and the brush roller doesn’t really need anything done to it.” She empties the dust bag twice in six months and her cleaning solution is only half empty after that period.
BrianD particularly appreciates the maintenance design compared to competitors: “The tanks are mounted fairly high, so you don’t have to bend over as much to change them. And as mentioned they are smaller—and LIGHTER.” He also notes the dust bag mounting: “The Dreame and some others mount low on the unit. You have to pull off a panel on the front towards the floor…This one mounts vertically and is much more accessible, you can see the mounting rails from above.”
The roller mop retracts into the unit when climbing the dock ramp, preventing dirt from being dragged up. BrianD observed: “The only place that gets a little nasty is the little tray where the mop pad is cleaned—but it lifts out and is simple to clean. Very nice design—and far easier to clean that the mop-pad washing area of the Dreame or any others with rotating pads.”
The main maintenance complaint is noise. The base station self-cleaning cycle runs for 2-3 minutes at high volume after each cleaning session. BrianD acknowledges: “The emptying cycle is a little loud—but to me that’s an effect of a very strong suction in the base—it empties the dust bin and sucks out the filter very well.” He initially moved the base due to the noise but accepts it as a tradeoff for thorough cleaning.
Replacement parts and consumables are readily available on Amazon. One complaint that appears multiple times is the cost of eufy’s proprietary cleaning solution at $26 for a small bottle, though the solution lasts months even with daily use.
Carpet Performance: The S1 Pro’s Main Weakness
While the S1 Pro excels on hard floors, carpet performance is its Achilles heel. According to Vacuum Wars, it “struggled with vacuuming embedded debris, scoring below average in carpet deep clean evaluations.” The robot also got stuck on longer pile carpets and rugs during testing.
Jake confirms this limitation: “Third, the vacuum is just okay. It works great on solid surfaces and average on carpeting. The thicker the carpet, the worse it will do. Fourth, it really struggles with height transitions.” His household has thick shag rugs on carpet pads in living rooms, and the robot “cannot consistently climb them, so we have blocked them as no-go zones in the map and just vacuum by hand.”
For low-pile area rugs and thin carpets, owners report adequate performance. Heather M., who runs her S1 Pro daily across hardwood, low-pile area rugs, and medium-pile bedroom carpet, finds it sufficient: “The bedrooms that are carpet and also a high traffic area, I do still vacuum with my upright, but I found that having this Eufy supplementing my upright vac is a great help with all the pet hair!”
Yaniv had to work around one specific bathroom mat: “There is a specific bathroom mat we use which for some reason this robot tried to vacuum and ends up sucking it to its vacuum port, getting the robot stuck.” He solved this by placing a small stool to block access or could have used a virtual barrier in the app.
The S1 Pro automatically lifts its mop roller when it detects carpet to avoid wetting it, which works well for thin carpets but contributes to problems on thicker pile where the lifted roller affects navigation.
Who Should (and Shouldn’t) Buy the Eufy S1 Pro
The eufy Omni S1 Pro is ideal for households that prioritize hard floor cleaning, particularly those with pets and high traffic. As Homes & Gardens reports, it can reduce traditional vacuum usage by up to 90% in homes with kids and pets on primarily hard flooring.
Buy the S1 Pro if you have:
- Mostly hard flooring (hardwood, tile, vinyl, laminate)
- Pets that shed heavily—multiple owners with shedding dogs and cats report excellent results
- Only low-pile area rugs or thin carpets
- Budget of $999-$1,500 (watch for sales at the $999 price point)
- Tolerance for 2-3 minutes of loud base cleaning after each cycle
Skip the S1 Pro if you have:
- Mostly carpeted floors, especially medium to thick pile
- Many high-pile rugs or thick carpet pads
- Significant floor transitions or thick thresholds
- Expectation of complete edge-to-edge mopping (it leaves ~1.5 inches along walls)
- Need for absolute quiet operation
For multi-story homes, the S1 Pro can map multiple floors, though the process is “a bit clunky” according to Jake. You need to start it on the primary floor, pause, carry it to the new floor, and unpause. It will clean but roam looking for the base until the battery dies. Several owners mention wanting to purchase a second unit for additional floors rather than carrying it up and down stairs.
Maui John sums up the ownership experience after months of use: “This has been some of the best money I have spent in a long time…It really has changed my life for the better in a way that I see and feel on a daily basis.” For the right home—one with extensive hard flooring—the eufy Omni S1 Pro delivers transformative daily cleaning that lives up to its premium price tag.
App Features and Smart Home Integration
The eufy app receives consistent praise for its intuitive design and comprehensive features. Owners can pause mid-clean, adjust suction power and water levels, schedule multiple cleanings per day for specific rooms, and set no-go zones—all from a well-designed interface.
Kunani highlights a key practical feature: “The best feature is setting up multiple schedules during the day to do only certain rooms (our cat litter box room multiple times a day) and then a couple full mop schedules so we wake up to a clean floor and go to sleep with a clean floor.”
Maui John appreciates the educational elements: “Within the app, there are well done videos that demonstrate features or help with troubleshooting (very clever). I can order consumables (bags, soap, parts) from within the app.” The app also offers tech support via live chat or phone.
The robot provides voice notifications about its progress and status. Dawn schedules hers to run overnight: “That area is programmed to clean twice a week to sweep and mop at night while I sleep with medium water level and turbo suction x1 pass…When I wake up, my floors are clean, and the mop is drying itself.”
One minor frustration mentioned by Dawn is the learning curve for cleaning rooms not on the regular map: “It’s a little tricky to get it to do a new location, I have a large house so there’s several rooms we rarely use so they’re not on a map, but I’m always able to do a little trial and error and get it to clean those less used rooms, I don’t really see instructions anywhere on how to do it exactly without tinkering with it.”
Value Comparison and Long-Term Ownership
At $999-$1,500 depending on sales, the eufy Omni S1 Pro sits at the premium end of eufy’s lineup but remains more affordable than flagship models from Roborock, Dreame, and Ecovacs. According to Vacuum Wars, it’s “the most expensive top-of-the-line robot vacuum currently available from Eufy, but it’s still slightly more affordable than flagship models from other brands.”
BrianD recommends waiting for sales: “I recommend it (but be sure to get it on sale for $1,000, don’t pay the $1500).” Multiple reviewers mention purchasing at the $999 price point and feeling it represents excellent value at that level.
Long-term ownership reports are positive. Dawn’s six-month review confirms reliability: “I waited 6 months to write this review, so I could really give an informed review…This thing works exactly like it’s supposed to.” Similarly, Jake’s 5-6 month experience shows “it’s been almost flawless in that time.”
Replacement parts remain affordable and available. Heather M., who used her older eufy model daily for over a year, reports: “I have replaced the filter a few times and bought a 12 pack of replacement filters and brushes for like $12 on Amazon. Have only had to use a few so far!”
Eufy’s customer service receives special recognition. One owner whose original unit developed issues after 10.5 months called support and described the representative as “extremely polite and helpful.” After troubleshooting, they received a replacement within days. Kunani had a similar experience: “Bought this and must be my luck but it had an error when mopping. Eufy replied within a day and sent me an entirely new unit to swap out and it’s worked flawlessly!”
The time savings translate to real quality-of-life improvements. Dawn explains: “It frees up my time to do my other house cleaning chores, and my floors look great…I spent hours a week on floor cleaning” previously. Maui John calculates: “The 30 seconds it takes each day to empty the canister, is worth my time of not having to vacuum and sweep my 1000 square foot of floors.”
