Introduction
The S1 Pro is a hybrid robot vacuum and mop system built around a motorised HydroJet mop and a fully automated UniClean station. It pairs a rotating, self-refreshing mop head with a dock that handles emptying, washing, drying, and refilling so the robot can return to cleaning with minimal user intervention.
This product is aimed at people who want deeper wet cleaning than a standard robot mop can provide, but without the daily effort of laundering mop pads and emptying wastewater. If you have mixed flooring—hard floors and low-pile carpets—or want a hands-off solution for frequent floor maintenance, this is positioned to help.
Quick verdict: The S1 Pro stands out for automated mop maintenance and a mop head designed to mimic hand scrubbing, but you’ll need to verify connectivity and space requirements before buying.
What’s in the Box
- Not specified (manufacturer components list not provided in the input)
If you need exact inclusions (robot unit, UniClean station, sealed dust bag, power cable, detergent sample, user manual), check the retailer listing or manufacturer packaging details before purchase.
Design & Build
The S1 Pro combines a square-profile robot chassis—optimised for corner-to-edge reach—with an 11.4-inch motorised mop combo that refreshes itself during operation. The mop module spins at a reported 170 RPM and applies approximately 1 kg of downward pressure to replicate the scrubbing action of a hand mop (source: listing, checked 2025). The system uses a dual water reservoir and fills the mop with ozonated water for what the maker calls “Eco-Clean Ozone.”
Materials and finish are described in marketing as streamlined with a sports-car-inspired silhouette; the listing highlights style as part of the visual appeal. Exact chassis materials, total weight, and the robot’s overall footprint are not specified in the supplied information, so confirm those numbers if clearance under furniture or transportability is a factor for you.
Ergonomics are largely handled by automation: you won’t lift the robot frequently if you place the UniClean station in an accessible spot. The dock itself is a 10-in-1 hub (auto emptying, auto washing, auto refilling, heated air drying, ozone cleaning, wastewater collection, detergent dispensing, LCD touch control, sealed dust bag, and faster charging) so maintenance reduces to occasional bin and supply checks.
Key Features
HydroJet Roller Mop with Instant Clean Mop Combo
Benefit: The rotating mop head and on-the-fly mop refresh are designed to remove fine, hard-to-see dirt and tackle marks that spray-and-wipe robot mops might leave behind.
Where it helps: High-traffic kitchens, entryways, and homes with sticky spills where a little mechanical scrubbing makes a tangible difference in results. The manufacturer states 170 RPM and 1 kg downward pressure to simulate manual scrubbing (source: listing, checked 2025).
Dual Water Reservoir with Ozonated Water (Eco-Clean Ozone)
Benefit: Two reservoirs allow separation of clean and wastewater, so the mop is rinsed with fresh, ozonated water while used water is collected separately. The ozonation step is marketed as an eco-clean process.
Where it helps: Households concerned about bacteria buildup on mop cloths or those who prefer an automated sanitation step after wet cleaning. If you have respiratory sensitivities or specific ozone concerns, consult manufacturer guidance before use; the presence of ozonated water is stated in the listing (source: listing, checked 2025).
10-in-1 UniClean Station (Auto Maintenance Hub)
Benefit: The docking station consolidates routine maintenance—emptying debris, washing the mop, refilling water, dispensing detergent, heating and drying the mop, collecting wastewater, and charging—reducing hands-on upkeep.
Where it helps: Anyone who dislikes post-cleaning chores. Apartment dwellers and busy households gain the most because the station lowers the frequency of manual intervention. The listing also claims a sealed dust bag and a 20% faster charge compared to the prior model (based on internal testing) to speed turnaround (source: listing, checked 2025).
Potent Suction for Mixed Floors
Benefit: The unit is promoted as having strong suction to lift hair and embedded soil from hard floors and carpets.
Where it helps: Pet owners and homes with short-pile rugs where debris can get lodged. The listing calls the suction “incredible potent suction,” but no numeric suction rating (Pa) is provided; real-world performance will vary by surface and traffic level (source: listing, checked 2025).
Corner-to-Edge Cleaning with Square Design
Benefit: The square chassis improves contact with walls and corners compared with circular robots, helping the cleaning head reach edge zones.
Where it helps: Rooms with baseboards, narrow gaps, and tight corners where edge dirt accumulates. If edge performance matters, the design aims to address that specifically.
Sports Car Streamlined Styling
Benefit: A design approach meant to look more like a modern appliance than a utilitarian gadget.
Where it helps: Buyers who care about appearance and want a robot that blends with contemporary interiors will appreciate the styling, though this is a subjective advantage rather than a functional one.
Wi‑Fi Requirement: 2.4 GHz Only
Benefit/limitation: The product requires a 2.4 GHz router or a dual-band router configured to support 2.4 GHz; it does not support 5 GHz Wi‑Fi.
Where it helps/limits: If you rely on a 5 GHz-only network, you’ll need to enable or add 2.4 GHz support for setup and remote app control. This is an important pre-purchase check for users with advanced home network setups.
Performance & Use
Practical setup tips
- Place the UniClean station against a wall in a ventilated area where wastewater can remain contained; the station handles wastewater collection but needs occasional emptying.
- Ensure your Wi‑Fi router broadcasts a 2.4 GHz SSID or configure your dual-band router for 2.4 GHz before initial setup. The robot will not pair through 5 GHz-only networks (source: listing, checked 2025).
- Add the recommended detergent and follow the manufacturer’s guidance for the water-to-detergent ratio if you intend to use the automatic dispensing function—this can affect cleaning results and reservoir maintenance.
Daily use and cleaning advice
- For sticky or heavy messes, spot-clean first. The S1 Pro’s mop simulates hand scrubbing but is not a substitute for manual removal of large spills.
- The manufacturer advises against using the robot for cleaning large volumes of liquid waste to avoid damage to the robot (source: listing, checked 2025).
- Expect the UniClean station to reduce manual washing—check and replace the sealed dust bag and empty wastewater as the system indicates or per the app schedule.
Maintenance expectations
- The 10-in-1 UniClean reduces the frequency of hands-on maintenance but does not eliminate it. You’ll still need to replenish water/detergent, replace the sealed dust bag periodically, and clean filters on a schedule the app or manual recommends.
- If using ozone-clean cycles, ventilate the room per local guidelines if you have concerns about ozone exposure; the listing mentions Eco-Clean Ozone but does not include ozone concentration figures.
Performance caveats
- Suction and mop performance claims are qualitative in the listing. If you want quantified suction power, battery run time, or exact coverage per charge, these numbers are not provided in the supplied material and should be verified on the manufacturer’s specification sheet or retailer page.
- The faster charging claim—20% faster—comes from eufy internal testing against a previous generation; individual results will vary with battery condition and environmental factors (source: listing, checked 2025).
Pros vs Cons
| Pros | Cons |
|---|---|
| Automated 10-in-1 UniClean station reduces regular maintenance (auto empty/wash/refill/dry/dispense) (source: listing, checked 2025) | Exact run-time, suction Pa rating, and robot dimensions are not listed in the supplied details — verify before buying |
| HydroJet mop rotates at 170 RPM and applies ~1 kg downward pressure for stronger scrubbing action (source: listing, checked 2025) | Not suitable for cleaning large amounts of liquid waste—manufacturer advises against it (source: listing, checked 2025) |
| Dual water reservoirs with ozonated water and wastewater separation aim to keep the mop cleaner between cycles (source: listing, checked 2025) | Uses 2.4 GHz Wi‑Fi only; will not connect on 5 GHz-only networks which may complicate setup for some users (source: listing, checked 2025) |
| Square chassis for better edge and corner reach compared with circular robots | Ozone-based cleaning may concern users with respiratory sensitivity; check manufacturer guidance (ozonation is mentioned, but no exposure figures provided) |
| Sealed dust bag in UniClean station simplifies debris disposal and reduces dust exposure | Some performance claims (e.g., “incredible potent suction”) have no numeric backing in the provided information — expect variance by floor type |
Who Should Buy
- Busy households that want an automated, low-touch mopping workflow: If you dislike laundering mop pads or emptying wastewater, the UniClean station substantially reduces those chores.
- Homes with mixed hard flooring and low-pile carpets: The combined vacuum-and-mop design plus stronger mechanical scrubbing can improve overall cleanliness for everyday messes.
- People who prioritise edge cleaning: The square design is beneficial if corners and baseboards are problem areas in your home.
Who Shouldn’t Buy
- Users who need the robot to handle large liquid spills or puddles: The manufacturer explicitly advises against cleaning large amounts of liquid waste (source: listing, checked 2025).
- Households with 5 GHz-only Wi‑Fi setups and no easy way to enable 2.4 GHz: The robot requires a 2.4 GHz connection for app connectivity (source: listing, checked 2025).
- Buyers seeking fully quantified specs: If you require precise suction power, runtime, weight, or dimensions before purchase, those figures are not supplied in the provided listing content—get the official spec sheet first.

Roomba 2 Essential Review — Compact Auto-Empty
SeaWar –
After debating between a Xiaomi robot at twice the price and a Roomba for more than twice as much, I chose the Eufy after researching many specialty sites — and I’m very satisfied (my wife is, too).
The Eufy 11s is a budget robot and lacks some “premium” features you’ll find on robots costing up to four times more, like laser navigation or a camera. I use it in the baby’s room and our studio apartment (about 50 m² of tile) and it cleans wonderfully. The first week it pulled out so much dirt, hair, and dust we could hardly believe it.
I like that it has two side brushes that sweep in debris and dust. Be careful with loose cables or fringe/shag rugs — it’s easy for the brushes to get tangled. That’s not unique to this model; many robots have those issues. On average I empty the bin once a week. It doesn’t fill up much since we don’t have pets, but we bring in dirt from the garden almost daily.
It comes with 4 replacement side brushes and 4 HEPA filters; expect to change the filters roughly every 3 months. You can clean the filters with a regular vacuum or a brush attachment. Battery life is about 1.5 hours in Auto mode (the robot detects the surface and adjusts suction power).
One feature I liked that few reviewers mention is the remote control. It has scheduling by time, start, return to base, spot clean, edge-only clean, single-room clean, and — best of all — arrow buttons that let you drive the robot like an RC car. That’s awesome if it gets stuck, if you want to target a specific spot, or just for fun.
I also used it in the living room (around 120 m²) with two carpeted areas. It cleaned the tile fine and automatically increased power on the carpets, leaving them very clean. Be careful when emptying the tray — a big cloud of dust can come out if you’re not careful.
Overall, it’s a great robot at a great price, especially during sales like Hot Sale or Black Friday. The replacement parts sold locally aren’t Anker-branded but are 100% compatible, and there are lots of YouTube videos showing maintenance and part replacement.

I bought this to replace a pair of high-end robot vacuum and mop units from a leading competitor that were only two years old but had a few annoyances—especially the mop. I have a 1,500 sq ft ranch with hardwood, tile, and rugs.
Pros:

I plugged Eufy in and watched the light blink orange for a couple of hours while she charged, then turn blue when she was done. I pressed the button to start cleaning and she beeped — then the light blinked orange again (charging for about an hour), then blue. I tried the remote; same thing. I couldn’t get her to run.
It turned out to be operator error: my cataracts make my vision so poor I couldn’t see the on/off button in the instructions or on the bottom of the unit. This morning I felt around, found the toggle, and hey — happy days! Eufy worked like a dream: quiet enough not to disturb me, but loud enough to hear where she was when I was nearby.
Before testing Eufy I vacuumed and damp-mopped. I have a long-haired cat and long hair myself, so after about 20 minutes — when she’d been working under my bed where the cat sleeps — I checked the dust bin. It was full. The unit is small and gets under furniture very well (so does my cat), so it collected a lot of hair. The roller brush was matted; I removed, cleaned, and replaced it. By the time she finished a full cycle and docked herself I had emptied the bin three times and she still had more. Emptying the bin and cleaning the brush are intuitive and easy; the small cleaning brush is very helpful for removing hair. I expect it’ll take a few runs to get all the cat hair under control, then I’ll figure the right maintenance schedule.
One reason I bought Eufy is gardening — I track dirt and sand into the house, which is rough on bamboo and hardwood floors. I can now come in from the garden, push Eufy’s start button on my way to the shower, and let her take care of the mess. That will save me energy and keep my floors in better shape.
About Eufy “skipping rooms”: I found a couple of easy fixes. I cleared the floor in my daughter’s 10×13 room, put Eufy in, shut the door, set a 20-minute timer and she did a thorough job — after first traversing the living areas on her way there. I’m going to clear and close off rooms (office, family room) so she focuses on one area. I also plan to try temporary non-adhesive strips across transitions to keep her in a room without sticking anything to my bamboo floors. I did have to tuck in the bedskirts to get her under the bed — she seemed reluctant otherwise.
One safety question: when Eufy is docked, are the exposed silver charging contacts a shock risk if my cat lies on the charger or my grandson rolls a metal toy over them? The charger needs to be plugged in for Eufy to find her way home, and I’m not always watching it, so I’m cautious about those contacts.
I suggested Eufy make a large-print quick-start guide available on their website or by phone. The instructions use delicate line drawings and small print that are hard to read for those of us with vision issues. A bold, larger-print or downloadable version would help many older customers.
As an older gardener who doesn’t want to haul a heavy vacuum or get down on hands and knees, I’m thrilled with this unit. It will be especially good for people who are busy with grandchildren, volunteering, second careers, or caregiving. I didn’t have to drag out the heavy vacuum today and by the end of several runs the house will be much less “fuzzy.” I’m already thinking of this as a Christmas gift for three people. I hope Eufy has a long, healthy life — I’ll move a little furniture to help her along. Go for it, Eufy!

If you have pets, this is a must-have — even in a house with a cleaning staff. It picks up dust, pet hair, dirt and all kinds of debris, especially under beds, sofas and other furniture. I previously tried the Deebot 500 and it was night-and-day worse: loud whining/grinding while moving, constant app disconnects, and an overall frustrating experience.
This Eufy doesn’t have an app or Alexa/Google Home integration, but don’t let that put you off — it comes with a physical remote that’s actually more useful in some ways. You can’t set multiple scheduled cleanings like with Deebot’s app, but you can manually drive the robot (full directional control, including reverse and forward acceleration). That manual spot-clean capability is brilliant for quickly targeting a dirty area and then sending the robot home.
Speaking of going home, the return-to-base function is light years ahead of Deebot. It finds the charger very intelligently: it follows walls from room to room until it’s roughly 10 feet away, then moves straight to the charger. Even with furniture blocking line of sight, it navigates around obstacles when close. It feels like it’s using some kind of laser-based detection — impressive for the price.
In my 2,400 sq ft house this is the first robot vacuum that reliably cleans on schedule and returns to its base about 95% of the time — and that reliability is the most important thing for a robot vacuum. The included boundary strips are handy (I put them at the balcony and entrance doors and it never crosses them), and they even include a spare HEPA filter.
Overall, a very good package for the price.

This Eufy is fantastic. My husband and I live in a 750 sq ft condo with laminate floors (except a tiled bathroom) and we keep things very tidy — we vacuum daily with our Dyson and deep-clean weekly. With my upcoming back surgery, I decided to get this robot to help maintain the place. It arrived yesterday, was a breeze to set up, and charged quickly.
I wasn’t expecting much since my husband vacuumed that morning, but when I emptied the dirt bin I was stunned — it was already half full of dust and debris from what we thought was a clean floor. Incredible. It’s very quiet, nudges furniture gently instead of crashing into it, and the magnetic boundary strips work perfectly. We used them around our puppy’s pee pad (no risk of the robot dragging accidents around — thank goodness). Highly recommend — we’re extremely impressed!
Melana –
Great purchase. It cleans our busy apartment well—navigating around the kids’ toys and picking up dust effectively, though its path can be somewhat random. Minor docking issues: sometimes it oscillates at the charger or stops a few inches short, and it tends to bump into black objects.

Honestly, this is a very good robot vacuum for the price — it cleans exceptionally well. Its suction is much stronger than similarly priced iRobot models. It has a scheduling feature and, despite basic tech, is surprisingly smart: it doesn’t fall, doesn’t crash hard into things, and rarely gets stuck. While it’s not truly high-end smart and sometimes it’s better to guide it with the remote, for the price you can’t beat it — it does its job very well and reasonably efficiently. It picks up all kinds of debris, hair, and even managed to pick up a broken plate I dropped. Excellent product; I definitely recommend it. The only extra I find unnecessary are the magnetic strips — they serve as a digital barrier but I wouldn’t use them much.

One-year update:I bought two Eufys in August 2019 and run them about once a week or every two weeks. Over the year I’ve noticed a few quirks. Sometimes a unit just stops in the middle of a room with the blue light on and no error beeps — hitting Start on the remote gets it going again. Other times it stops and beeps with a blinking light; keep the manual handy. One instance was caused by hair wrapped around the front pivot wheel — I popped the wheel off, cleared the hair, pressed the reset button on the bottom, and it worked fine. Another time it got to the top of the stairs, couldn’t turn around and started beeping; I wiped the three bottom sensors, reset it, and it was fine. There have been days where it repeatedly stopped with no apparent reason (no beeps and fully charged) and I had to reset it from the bottom button several times before it finished a room — once it took about 10 resets that day.
Over the winter a stray long-haired cat moved in and sheds a lot. Eufy doesn’t pick up large tufts from my rugs, so I use a hair mitt on the worst spots first and then Eufy cleans the rugs well. Tip: use the magnetic strips to divide larger rooms. My living room would take forever for Eufy to cover, so I split it in half — when one half looks done I pick up Eufy and put it in the other half. That works well. You can also stick the magnet strips to the side of your refrigerator for storage, which I find handy.
You do need to clean Eufy between charges. My routine is to break the house into zones: living room and kitchen — clean, then charge (about 4.5 hours); hallway, bathroom, bedroom — clean, then charge; finally my office/sewing room — clean and charge. It only takes 5–10 minutes to clean the unit between uses. I’m still thrilled to have these and I’ve decided I’ll never be without a robot vac again. I bought them partly because of the Anker name — I’ve owned other Anker products for years and they’re well made.
Initial purchase experience:I bought two more of these yesterday on a Deal of the Day and received them today. Both took about three hours to fully charge and then they were off to work. One went downstairs and the other upstairs. I checked on them periodically. I found the downstairs unit stuck in a couple of odd spots (on top of a small table base and lodged next to my furnace) — I’ll block those areas next time. The upstairs unit spent 45–60 minutes in the kitchen — a bit OCD, but the kitchen was very clean, rugs included. They do an excellent job on edges; the upstairs unit even followed the curve around a table pedestal and drove over my thick wood floor vent covers. They fit under almost all my furniture — unlike a Roomba I returned years ago — except a lowboy chest and three smaller tables where I’ll use a Swiffer. The drop sensors worked perfectly at the stairs and the vac turned away instead of falling.
The upstairs Eufy finished the kitchen, living room and entryway and was in the bathroom when the red light came on; it’s now charging. Both units ran for the 100 minutes stated in the manual. I emptied the upstairs bin twice (only because I paused the run to move it out of the kitchen), and although the bin wasn’t full it collected plenty of dirt and fuzz — very satisfying.
I chose not to program a schedule since I don’t need daily cleanings — it’s just me and no pets anymore (until the stray showed up), so I’ll run them manually once or twice a week. For the first cleaning I picked everything up off the floors, but that was a pain and not something I’ll do again — it defeated the purpose of having robot vacs. I’ll leave cords zip-tied but everything else will stay put.
Bottom line: I am over the moon with these. Vacuuming is one of my least favorite chores and these will definitely be used weekly. They’re very quiet — you can’t always hear them even in the same room when they’re cleaning under furniture. They were an excellent price and better suited to me than the very expensive robot vacs. I also prefer not having to use an app or Wi‑Fi to run them. In my opinion these are worth every cent.
