ECOVACS WINBOT MINI vs W2 PRO Omni

WINBOT MINI vs W2 PRO Omni at a glance

Head to head

The best result in each row is marked, based on my testing and the manufacturer specs. Where the robots tie, both are marked.

The tally is a guide, not my verdict. The size of your windows matters more than any single row.

Compact corded vs station robot

Before comparing features, decide which kind of robot your windows need, because that decides more than any spec.

The WINBOT MINI is a compact corded robot✕Corded robotA window robot that runs on mains power through a long cable. It has no battery limit, but needs an outlet within reach. A small built-in battery only holds it on the glass if power is lost.. It plugs into the wall, ties to a safety rope and has a small battery that only holds it on the glass for about 30 minutes if the power fails.

The WINBOT W2 PRO Omni is a station robot✕Station robotA window robot that docks in a portable base. The base stores and charges it, holds solution and anchors the safety rope, and can run the robot on battery away from outlets.. Its portable 6-in-1 station stores the robot, holds the solution, anchors the rope and runs it on battery for up to 110 minutes, or plugged in.

Our tip: Measure your biggest window and check where the outlets are before choosing, because those two facts pick the robot for you.

Design, size and storage

The MINI is about 8.46 by 8.46 inches and about 2.17 inches thick. It drives on two tracks with four side rollers and spherical corner sensors, and its pad has no bumper so it can creep a little closer to the frame.

The W2 PRO Omni is a full-size square robot. With its station, the kit weighs about 19 lb, which I could still carry from room to room with one hand.

Storage is the biggest daily difference. The MINI lived in a bathroom drawer. The W2 PRO Omni lived in its station in a hall closet.

The WINBOT MINI is small enough for narrow panes and mirrors.

Setup and the first week

The MINI took about 2 minutes to set up per session, plus a minute or two watching the cable on large windows and about a minute of finishing wipe.

The W2 PRO Omni took about 3 minutes to set up, under a minute to move to the next window and about 2 minutes to pack away.

Both scored 7.4 in week one. My only complaint about the MINI was the pad mark where it parked, and my lesson on the W2 PRO was to treat the rope as part of the robot.

Suction and safety

Neither robot came off the glass in four weeks. The W2 PRO Omni scored 9.0 for safety and the MINI 8.4.

The MINI is rated at about 7,500 Pa and has a 9-stage protection system. When I pulled its plug mid-run, it held on and beeped loudly.

The W2 PRO Omni’s rope ties to its station, which sits on the floor as a stable anchor, and it has 12-stage protection. On low battery it alerts you and returns toward its starting point.

My safety scores

Scores out of 10 for grip, alerts and anchoring.

For upstairs outside glass, either robot beats a ladder. The U.S. Consumer Product Safety Commission has reported more than 164,000 emergency room-treated injuries a year related to ladders.

How well they clean

On big glass, the W2 PRO Omni was the better cleaner. It scored 9.0 on dust and pollen, 8.8 on fingerprints and 8.0 on light kitchen grease.

The MINI did best on regularly cleaned glass. A window cleaned in the last month scored 8.4 after one Deep run, one cleaned last season 7.0 and one left for a year only 5.2.

On months of outside grime, both needed help. The W2 PRO Omni scored 6.2 in one pass and 8.4 after a second pass with a fresh pad, while the MINI scored 5.4 on street-side road film.

Center of the glass

My scores out of 10.

Our tip: Plan two passes and a fresh pad for neglected outside glass on either robot, because one pass left a haze on both.

Edges and corners

Neither of these robots has ECOVACS’ TruEdge scrubber, and both left some dirt in the corners.

Along the frames, the W2 PRO Omni scored 8.0 with its edge-focused mode on and 6.6 with it off. The MINI scored 7.4.

In the corners, the W2 PRO Omni scored 6.2 and the MINI 5.0, because its square pad leaves small square patches. On both, I kept a microfiber cloth handy for the corners and the parking mark.

Corners

My scores out of 10.

Along frames

Same week, similar windows.

Our tip: Turn on the W2 PRO Omni’s edge-focused mode for sliding doors, because it lifted my frame score from 6.6 to 8.0.

Power: cord vs battery station

This is the practical heart of the comparison. The MINI needs an outlet within reach of its cord on every window, and its cord and rope both trail from the robot.

On my tallest sliding door, the MINI reached the top only when I ran the cable and rope down opposite sides. Loose together, they left a dirty strip along the top. Snagged on the frame, the cable stopped it early.

The W2 PRO Omni ignores outlets. I ran it on battery about three-quarters of the time, and it covered every ground-floor window with charge to spare. ECOVACS rates it for up to 110 minutes and about 55 m² per charge.

Our tip: Run the MINI’s cable and rope down opposite sides of the window, because that fixed its early stops on tall doors.

Modes and controls

The MINI offers Quick, Intensive, Deep and Spot. ECOVACS rates Quick at about 1.1 sq ft a minute, Intensive took me about 1.4 times as long and Deep about twice as long.

The W2 PRO Omni keeps it simple with standard cleaning and an edge-focused mode. That simplicity helped it score 8.7 for ease of use against the MINI’s 8.1.

The MINI comes with a remote for steering, but I found it fiddly. Its ECOVACS HOME app over Bluetooth was more useful, for spray, alert volume and a track-cleaning program.

Spray, tank and pads

The MINI sprays from four ultrasonic nozzles and holds about 60 ml. About 0.7 fl oz cleaned two large glass doors, so a full tank covers about 215 sq ft in Quick mode and about 160 in heavier modes.

The W2 PRO Omni sprays from three wide-angle nozzles, with solution stored in the station. ECOVACS says its water pressure is doubled over earlier models, and the mist was even and fine.

Pad condition decided results on the W2 PRO Omni. A fresh, damp pad scored 8.8, the same pad on a second dirty window 7.0 and on a third 5.2.

W2 PRO Omni: one pad across dirty windows

My scores out of 10.

Hard water matters on both. The U.S. Geological Survey classes water above 120 mg/L of calcium carbonate as hard, and those minerals dry into spots and slowly clog spray nozzles.

Our tip: Swap the W2 PRO Omni’s pad every three or four inside windows, because one pad carried to a third dirty window scored barely more than half of a fresh one.

Which homes suit each robot

After four weeks, the clearest way I found to choose was to picture the home rather than the robot.

A modern condo with floor-to-ceiling glass and a balcony is W2 PRO Omni territory. I rated it excellent there, and the battery station made the balcony a five-minute job.

A house with sliding or deck doors suits the W2 PRO Omni too. A family home with a mix of big and small windows was very good with it, though the small ones took longer to set up than to clean.

An older home with divided panes or a small apartment with two or three windows is where the MINI makes more sense. It fits the panes, lives in a drawer and plugs into the nearest socket.

Our tip: If you are torn, list your five most annoying windows, because the size of those five is the best guide to which robot you will actually use.

Which windows and glass suit each

The W2 PRO Omni was excellent on floor-to-ceiling glass, very good on sliding and French doors with edge mode and very good on balcony glass. Small windows were fine, but setting up the station took longer than the clean.

The MINI was very good on regularly cleaned windows and on narrow and small windows, good on sliding doors if I watched the cables and good on tilt-and-turn windows up to about 45°.

Neither suits arched shapes well, and the MINI is not suitable for tiled walls or sloped skylights.

Noise, pets and family life

The MINI was loud for its size. I measured it at 67 to 69 dB at about 3.3 feet, between normal conversation at about 60 dB and a vacuum at 75 to 80 dB.

The W2 PRO Omni made a steady whoosh, roughly like a hair dryer on low, audible in the same room and faint one room away.

With pets and children, the MINI has two lines on the floor, the cord and the rope. The W2 PRO Omni has one, the rope to its station.

How loud is it?

My reading for the MINI; others are typical reference levels.

A cleaning day with each

In week four, I gave each robot the jobs it suits best, then swapped.

With the W2 PRO Omni, a whole-house day took about 45 minutes of my own time: about 10 minutes of evening prep, about 25 minutes moving the station and clipping the robot on, and about 10 minutes rinsing pads.

With the WINBOT MINI, the bathroom mirror, the narrow front-door pane and the kitchen window took a few minutes each, plus about 3 minutes rinsing the pad and wiping the tracks. On the big patio door, the cord and the slower pace made it the wrong tool.

Cleaning and maintaining them

The MINI needs its pad rinsed and its tracks, rollers and sensors wiped after each session, about 3 minutes in all. Its app has a track-cleaning program.

The W2 PRO Omni needs its pads rinsed, about 4 minutes after a session, and its rope checked for fraying every few months.

Neither washes its own pads, and both pads can go in a gentle machine wash without fabric softener.

Our tip: Keep a microfiber cloth with whichever robot you buy, because both leave a small mark where they park.

Mistakes to avoid

Most weak results came from the same few habits.

My four weeks, week by week

Week one: inside glass. Both scored 7.4.

Week two: outside glass. The MINI dropped to 6.2 on dirty outside windows, while the W2 PRO Omni reached 8.2 on battery on the balcony.

Week three: the MINI recovered to 7.6 once I fixed the cable layout on tall doors, and the W2 PRO Omni dipped to 8.0 on neglected street-side glass.

Week four: routine use. The MINI finished at 8.0 and the W2 PRO Omni at 8.6.

Week four satisfaction

My weekly scores out of 10.

Real-life scenarios

These are the moments during testing where one robot clearly pulled ahead.

For homes with big glass, the W2 PRO Omni is the better first window robot.

My scorecard

These are my own scores out of 10, from my single reviews of each robot after four weeks of daily use.

Overall scores

My overall editorial scores out of 10.

The W2 PRO Omni wins overall because it cleans big glass better and works anywhere. The MINI is the better tool for small windows and mirrors near outlets.

Which one should you buy?

Start with the size of your glass.

If you have big windows, patio doors or a balcony, buy the W2 PRO Omni. If your glass is mostly small windows, narrow panes and mirrors near outlets, the WINBOT MINI is the better fit and far easier to store.

For everything I found, see my WINBOT MINI review and W2 PRO Omni review, or compare the compact Winbots in my WINBOT MINI vs MINI 2 comparison.

Living with them long term

The MINI needs a pad rinse and a track wipe after each session. The W2 PRO Omni needs pads rinsed and its station kept charged.

What I would change: a quieter fan and cleaner corners on the MINI, and stronger corners and pad washing on the W2 PRO Omni.

For small windows near outlets, the WINBOT MINI is the easier robot to own.

From manufacturer specifications and my own testing.

How I tested and compared them

I used each robot as my main window cleaner for four weeks, on mirrors, narrow panes, tilt-and-turn windows, patio doors, balcony glass and neglected street-side windows. A second HouseholdMe tester shared the robots, and we wrote the notes together.

I scored both on similar glass with the same solution, pulled the MINI’s plug mid-run to test its backup and timed every setup, session and cleanup.

I then checked my notes against ECOVACS’ specifications and owner documentation.

• Cleaning: dust, fingerprints, rain spots and months of outside grime.
• Edges: frames, inside corners and frameless edges.
• Safety: suction hold, power-loss behavior and the safety rope.
• Ownership: setup, pads, refills, storage and noise.
