The WINBOT lineup explained

ECOVACS names its window robots with a few building blocks. Once you know them, the lineup makes sense: the letter and number set the generation, PRO means more grip and better edge brushes, and Omni means it comes with a station.

There is one exception to that logic. The W2 PRO Omni is older than the W2S models, and its PRO refers to its station and safety features, not to 10,000 Pa or TruEdge 2.0.

The MINI is also sold as a 2026 version listing. It is the same compact design as the original MINI, so I treat them as one model in my scores.

Our tip: Decide between a station and a cord first, because that one choice cuts the Winbot lineup in half.

My test scores for all 8 WINBOTs

Every Winbot cleaned the same glass: a sliding patio door, two upstairs windows from inside and out, a frameless shower screen, a divided bathroom mirror and a narrow kitchen window.

The whole lineup is good, and the spread from top to bottom is small compared with the wider market. The real differences are power, edges and size, so the right Winbot depends more on your home than on the score.

The clearest gap is between the original MINI and everything else. Its lack of corner brushes shows on every frame.

Safety scores were the tightest group of all. Every Winbot has a tether, edge sensors and either a battery station or a backup battery, and none of the eight fell during my test.

Ease of use is where the range splits most clearly. The Omni models with buttons on the station were simply quicker to start, which is why the W3 Omni and W2S PRO Omni scored highest there.

The corded W2S PRO was the outlier. It cleans as well as anything in the range, but managing the cable and rope cost it points on ease of use.

WINBOT tech explained

Every Winbot holds on with suction measured in Pascals (Pa)✕Pascals (Pa)the unit used for suction. Higher numbers press the robot harder onto the glass, which helps on dirty or outside glass., drives on tracks and wipes with a microfiber pad. What changes from model to model is how it navigates, how it cleans the edges and how it is powered.

WIN-SLAM navigation

WIN-SLAM✕WIN-SLAMECOVACS’ navigation system for window robots. It measures the pane, detects frames and obstacles and plans a route instead of wandering at random. comes in three generations across the lineup. The MINI uses 3.0, most of the range uses 4.0 and the W3 Omni has 5.0.

In my test, 4.0 and 5.0 were noticeably better at mapping large and odd-shaped panes. On a small mirror, the difference was hard to see.

TruEdge and corner brushes

TruEdge✕TruEdgeECOVACS’ edge-cleaning system. A scrubber or brushes drop down along the frame and spin to clean the strip a flat pad misses. TruEdge 2.0 uses brushes that reach further into corners. is the biggest single upgrade in the range. The W2S Omni and W3 Omni use the original scrubber, the W2S PRO models use the TruEdge 2.0 brushes and the MINI 2 has four corner brushes instead.

How much I had to finish by hand along the frames of my patio door, my estimate. Shorter is better.

Spray

Every current Winbot uses an ultrasonic spray, which turns the solution into a fine mist. The MINI 2 has the finest, with droplets as small as 10 microns, and it showed on mirrors, where it left the fewest drip lines.

The W-series models spray a little more generously, which helps on dirty outside glass. On a mirror, I turned the spray down in the app.

Omni stations

The Omni station holds the robot, the solution and the tether, and it powers the robot from its own battery. On the W2S PRO Omni it adds a display, and on the W3 Omni it adds a pad-washing system with 16 jets.

Corded Winbots use a backup battery✕Backup batterya small battery that keeps the suction fan running if the cord is pulled out or the power fails, so the robot stays on the glass while you bring it in. instead. Both approaches were safe in my test, but the stations were more convenient on balconies and upstairs windows.

The W3 Omni’s station adds pad washing to the battery, storage and anchor of the other Omni stations.

1. ECOVACS WINBOT W2S PRO Omni

If you want one Winbot and do not want to overthink it, buy the W2S PRO Omni. It combines the strongest suction in the range, the best edge cleaning and the most convenient power system.

It scored highest overall and highest on safety of all eight Winbots, and it never felt out of its depth on any glass in my house.

Why it beats the other Omni models

Against the W2S Omni, it adds 2,000 Pa of grip and the TruEdge 2.0 brushes, which reached further into my frames. Against the W3 Omni, it trades pad washing for stronger grip and slightly better edges.

The station display is a small but useful extra. I could see battery and progress at a glance without opening the app.

Daily use

Carry the station to the window, clip the tether, place the robot and press start. When it is done it returns near the start point and you lift it off.

I cleaned every window in my house in one session on a single charge.

Four weeks with it

Over four weeks it became the robot I reached for by default. Whether it was the patio door on a Saturday morning or a quick clean of the bedroom window after rain, the routine was the same and took two minutes to start.

Its consistency is what impressed me most. It never had a bad day, and it never needed me to rescue it from a frame or a corner.

What to know before you buy

The station is heavy and the pads still go in the washing machine. If the pads are the part you hate, step up to the W3 Omni; if you do not need a station, the W2S PRO has the same grip and brushes.

The W2S PRO Omni’s TruEdge 2.0 brushes left the least for me to finish of any Winbot.

Pros

• 10,000 Pa and the best safety score in the range
• TruEdge 2.0 brushes for the cleanest frames
• Battery station with display, no outlet needed
• Handles every kind of glass in the house

Cons

• Heavy station
• Pads need washing by hand
• Edge brushes need regular cleaning

Who should buy it

• Most homes with big or high glass
• Anyone who wants one Winbot for everything
• Balconies and windows far from outlets

Who should skip it

• Homes with only small windows
• People who never want to wash pads
• Anyone who will not carry a heavy station

2. ECOVACS WINBOT W3 Omni

The W3 Omni is the newest Winbot and the one that changes the routine most. Its station rinses both pads with 16 jets after every job, so you never scrub a dirty pad in the sink.

It also has WIN-SLAM 5.0, the newest navigation in the range, and the longest rated battery at 130 minutes.

Who it is really for

If you have a lot of glass and clean it often, the pad washing saves real time and mess. Over four weeks it cleaned as consistently as any robot I have tested.

If you clean a few windows twice a year, you will barely notice the difference, and the W2S PRO Omni is the better buy.

Our tip: Empty the W3 Omni’s dirty-water tank after every session, because standing water in the station starts to smell within a few days.

Versus the W2S PRO Omni

It has 8,000 Pa instead of 10,000 Pa and the original TruEdge scrubber instead of 2.0 brushes. In practice, that meant slightly more corner work for me, but far less pad washing.

Four weeks with it

My routine was to clean the whole ground floor on Sunday mornings. The robot went from window to window, the station rinsed the pads in between and I emptied the dirty-water tank at the end.

After four weeks of that, the inside of my sink was the cleanest it has ever been after window cleaning, which tells you everything about this robot.

What to know before you buy

Its station is the heaviest of all, it suits rectangular glass best and it leaves a small pad mark where it parks.

The Vortex Wash station is what sets the W3 Omni apart from every other Winbot.

Pros

• Station washes the pads automatically
• Newest WIN-SLAM 5.0 navigation
• Longest 130-minute battery
• Very consistent cleaning

Cons

• Heaviest station
• Less grip than the PRO models
• Leaves a small pad mark where it parks

Who should buy it

• Homes with lots of glass
• People who clean often
• Anyone who hates washing pads

Who should skip it

• Occasional cleaners
• Small apartments with few windows
• Homes with lots of stairs to carry it up

Choose this if you clean a lot of glass often and want the least work afterwards. Read my full WINBOT W3 Omni review.

3. ECOVACS WINBOT W2S PRO

The W2S PRO is the flagship without the station. It has the same 10,000 Pa of suction and TruEdge 2.0 brushes as the W2S PRO Omni, and its edge score of 8.9 is the second-best in the range.

It also has the most modes of any Winbot: seven, plus a manual joystick in the app.

Corded is not a compromise near outlets

If every window you clean is within reach of an outlet, you lose little by skipping the station. The robot cleans the same and is lighter to carry around.

Its backup battery held it firmly when I pulled the cord, and it sounded an alarm until I brought it in.

The trade-offs

You manage the cable and the loose safety rope yourself, and there is no station to store everything in one place. On upstairs windows, finding a solid anchor for the rope took more thought.

Our tip: Hang the W2S PRO’s cable over the top of the window with a meter of slack, because a cable that pulls tight is what makes corded Winbots drift off course.

Four weeks with it

I kept it in the hall cupboard with its cable coiled and the tether clipped on. For the patio door and the living-room windows, all near outlets, it was quicker to start than an Omni model.

Upstairs, I had to plan the cable route and find a solid anchor for the rope, which is where I missed the station.

What to know before you buy

It needs an outlet within cable reach. For balconies or windows far from power, go for an Omni model instead.

The W2S PRO has the flagship grip and brushes in a lighter, corded robot.

Pros

• Flagship 10,000 Pa grip and TruEdge 2.0 brushes
• Seven modes plus a manual joystick
• Lighter and simpler than the Omni models
• Backup battery if power fails

Cons

• Needs an outlet within cable reach
• Cable and rope to manage yourself
• No station for storage

Who should buy it

• Homes where every window is near an outlet
• People who want top edges without a station
• Anyone short on storage space

Who should skip it

• Balconies and outlet-free areas
• Lots of upstairs outside glass
• People who want a grab-and-go station

Choose this if your windows are near outlets and you want the best edges. Read my full WINBOT W2S PRO review.

4. ECOVACS WINBOT MINI 2

The MINI 2 is the Winbot for small glass. At about 21.5 cm across and 5.5 cm thick, it fits narrow kitchen windows, bathroom mirrors and shower screens where full-size Winbots do not.

Its four rotating corner brushes are its big upgrade over the original MINI. On my divided bathroom mirror, they made the difference between finishing every frame by hand and barely touching them.

Small but properly built

It grips at 8,000 Pa, uses WIN-SLAM 4.0 and sprays a mist with droplets as small as 10 microns. On mirrors, that fine mist left far fewer drip lines than the original MINI.

It stores in a drawer with its cable and tether, which suits apartments with no room for a station.

Where it struggles

On a big patio door it is slower than the W-series, and very dirty outside glass needed a second pass. It also needs an outlet within cable reach.

Four weeks with it

I used it mostly in the bathroom: the mirror twice a week and the shower screen after showers. It became part of the cleaning routine in a way the bigger robots never did indoors.

Because it is small and light, I also moved it around the house for the narrow kitchen window and the glass panel in the front door.

What to know before you buy

If most of your glass is large, buy a W-series Winbot and do the mirrors by hand. If most of it is small, this is the one.

Four corner brushes are what make the MINI 2 the best small Winbot.

Pros

• Four corner brushes clean close to frames
• Small enough for narrow panes and mirrors
• 8,000 Pa with a 30-minute backup
• Stores in a drawer

Cons

• Needs an outlet
• Slower on big glass
• Very dirty glass needs extra passes

Who should buy it

• Apartments with small windows
• Bathrooms with mirrors and shower screens
• First-time Winbot buyers

Who should skip it

• Homes with mostly big glass
• Windows far from outlets
• Neglected outside glass

5. ECOVACS WINBOT W2 PRO Omni

The W2 PRO Omni is the simplest way to get a Winbot with a station. Its 6-in-1 station stores, charges, powers, controls and anchors the robot and carries the solution, and it was the easiest station to carry.

It runs on battery or plugged in, and ECOVACS lists 12 stages of safety, including a rope tied to the station.

8.7Ease of use

Where it fits in the range

It is older than the W2S models and does not have TruEdge, so its edge score of 7.8 is the lowest of the stations. Everyday cleaning was good, but neglected outside glass needed two passes.

What you get instead is the lightest station and an easy routine, which mattered more than I expected on a balcony and upstairs.

Four weeks with it

I kept it by the balcony door and used it every week or so. Lift the station, carry it out, start the robot, and it was done before I had finished a coffee.

Over four weeks, its simplicity made it the station I used most casually, even if its edges were not the best.

What to know before you buy

If edges matter to you, the W2S Omni is worth the step up. If you just want a station that makes window cleaning easy, this is the value choice.

The W2 PRO Omni’s light station is the easiest Winbot station to carry.

Pros

• Lightest, most portable Winbot station
• Battery and plug-in modes
• 12-stage safety with a station-tied rope
• Easy controls on the station

Cons

• No TruEdge, so weaker edges
• Neglected outside glass needs extra passes
• Suction not officially stated

Who should buy it

• Balconies and apartments
• Buyers who want a station for less
• People who carry the robot between floors

Who should skip it

• Anyone who wants crisp edges
• Very dirty outside glass
• People who want pad washing

Choose this if you want an easy station Winbot for less. Read my full WINBOT W2 PRO Omni review.

Best Winbot by glass type

Station or cord: the decision that matters most

More than suction, edges or navigation, the power system decides how a Winbot fits into your life. I used four station Winbots and three corded ones side by side, and the difference was bigger than I expected.

If even a few of your important windows are far from an outlet, choose an Omni model. Extension leads through windows and balcony doors were the most annoying part of using corded Winbots.

If all your glass is near outlets and storage space is tight, a corded model is lighter, simpler and just as good at cleaning. The W2S PRO proves that: it scored the same overall as the W2S Omni.

Will a WINBOT fit your windows?

Size matters more than most buyers expect. A robot needs a pane larger than itself plus room to turn, and very small panes or glazing bars stop it completely.

The MINI is rated for windows from about 22 by 25 cm, which matches what I found: it worked on my narrow kitchen window and the small panel in the front door, where no W-series robot fitted.

Measure your smallest important pane before you buy. If several are under about 40 cm across, add a MINI 2 to your plans or choose it instead.

Our tip: Measure the glass inside the frame, not the whole window, because the frame and seals take several centimeters off each side.

Answer four questions and I will tell you which WINBOT fits your home. My single reviews go deeper, starting with the W2S PRO Omni review.

Or find your home below

The right WINBOT for your type of home

After living with all eight, I found the choice follows the home more than anything else. Here is how I would match them.

Small apartment

If your windows are small and you have a bathroom mirror and shower screen, the MINI 2 is the natural choice. It stores in a drawer and handles every small pane.

If your apartment has a balcony door or big living-room windows, add or choose the W2 PRO Omni for its light station.

Family house

A house with patio doors, several windows and upstairs glass is W2S PRO Omni territory. Its station handles the stairs, its grip handles the upstairs outside glass and its brushes handle the frames.

If you clean every couple of weeks, the W3 Omni’s pad washing will save you a lot of sink time.

Home with a conservatory or glass walls

Lots of large glass rewards the W3 Omni’s 130-minute battery and the W2S PRO Omni’s grip. The original TruEdge on the W3 Omni and W2S Omni also handled conservatory frames well.

Renters and small storage spaces

Corded models are lighter and smaller to store. The W2S PRO gives you flagship cleaning in the smallest footprint among the full-size Winbots.

Our tip: Buy for your largest and highest glass, not your average window, because that is the glass that decides whether you keep using the robot.

What each step up the WINBOT range gets you

The two biggest jumps are from the MINI to the MINI 2, where corner brushes change the result on every frame, and from the W2 PRO Omni to any TruEdge model.

The step from the W2S PRO Omni to the W3 Omni is about convenience rather than cleaning. You get cleaner pads, not cleaner glass.

Our tip: Skip the original MINI unless you find it on a very good deal, because the MINI 2’s corner brushes are worth far more than they cost.

What to look for when choosing a WINBOT

Within one brand, the choice comes down to four questions. Answer them in this order and the right Winbot usually picks itself.

1. Station or cord?

   If any important window is far from an outlet, choose an Omni model. If all are near outlets, a corded model saves weight and space.

2. Big or small glass?

   For mostly small panes, mirrors and showers, choose the MINI 2. For anything else, choose a W-series model.

3. How much do edges matter?

   TruEdge 2.0 on the W2S PRO models is the best, then the TruEdge scrubber, then the MINI 2’s corner brushes.

4. How often will you clean?

   If you clean often and a lot, the W3 Omni’s pad washing pays off. If you clean a few times a year, it does not.

How the WINBOT range evolved

ECOVACS launched its first window robot in 2011, and the current range shows how the design has matured. The big changes have been in edges, navigation and power.

For buyers, that history explains the price ladder. The newer features, especially TruEdge 2.0 and pad washing, are where the real cleaning and convenience gains are.

The ECOVACS app and controls

Every current Winbot works with the ECOVACS HOME app, which offers cleaning modes, scheduling where supported and a manual joystick on some models. The MINI connects over short-range Bluetooth for its remote-style controls.

The Omni models also have buttons on the station, which I used for most everyday jobs. The W2S PRO Omni’s station adds a small display with battery and task status.

My advice is to set your favorite mode once in the app, then use the buttons. The app is most useful for spot cleaning and steering the robot back over a missed mark.

Is a WINBOT worth it over cleaning by hand?

I kept a log of my window cleaning for the year before this test, when I did everything by hand, and compared it with four weeks of Winbots.

The robot did not beat a careful person with a squeegee on a single window. What it changed was how often I cleaned, because starting a robot takes two minutes and needs no ladder.

That is the real case for a Winbot. Clean glass becomes the normal state of the house instead of a twice-a-year project.

Getting streak-free results from any WINBOT

1. Use distilled water

   The US Geological Survey estimates about 85 percent of US homes have hard water, which dries as white spots. Distilled water leaves almost nothing behind.

2. Wring the pads well

   Damp, not wet. Drips are the main cause of lines on mirrors.

3. Avoid direct sun

   Warm glass dries the mist before the pad wipes it.

4. Use deep mode on the first clean

   Then switch to the standard mode for regular cleans.

How much each habit reduced streaks across the Winbot range, from my side-by-side runs.

Our tip: Use the ECOVACS solution only for the first deep clean of dirty glass, because distilled water alone gave me equally clear results on routine cleans.

Maintenance across the WINBOT range

1. Wash the pads after each session

   Warm wash, no fabric softener. The W3 Omni rinses them, but still benefits from a proper wash now and then.

2. Clean the edge brushes

   TruEdge 2.0 brushes and the MINI 2’s corner brushes collect hair and grit.

3. Wipe the tracks

   Dust on the tracks makes any Winbot slip.

4. Empty the tanks

   Including the W3 Omni’s dirty-water tank after every session.

5. Inspect the tether

   Replace it if it frays.

Common WINBOT mistakes

Our tip: Place any Winbot near the middle of the pane at the start, because WIN-SLAM measures the glass from where you put it.
