Table of Contents
There are more than 20 window cleaning robots on sale in Australia. Five clear the bar we set: Australian stock, a warranty someone here will honour, and enough owner feedback to judge. Most of the rest fell down on something basic: shipped from overseas with a warning that the manufacturer warranty may not apply, out of stock, or with almost no owner reviews. Here are the five, which windows each one suits, and why the rest didn’t make it.
For an ordinary house, the ECOVACS WINBOT W1S is the pick. It does the job on flat glass and stays on the window for over 30 minutes if the power cuts out. If your windows are upstairs or there are a lot of them, the WINBOT W2 PRO Omni is the one: it runs on battery and puts the power and safety cable into one line. If your panes are small, the WINBOT Lite fits windows the others can’t.
ECOVACS WINBOT W1S
The everyday ECOVACS pick. 5,300Pa peak suction and a battery that holds it on for over 30 minutes in a power cut.
Why this one →
ECOVACS WINBOT W2 PRO Omni
Runs 110 minutes on battery, so no powerpoint needed. One 5.5m cable does power and safety.
Why this one →
ECOVACS WINBOT Lite
215mm square and rated for panes down to 25cm × 25cm. Made for units and narrow windows.
Why this one →The other two: the WINBOT W3 Omni is the top of ECOVACS’ range and washes its own pad, but it has very little owner feedback in Australia yet. The TECHBEAR HCR-21 is the only non-ECOVACS robot that made the cut, and fine for ground-floor glass near a powerpoint.
Not sure which one fits your windows?
3 quick questions, then only the robots that fit.
Do window cleaning robots actually work?
On flat glass, yes. The robot holds itself on with suction, works out where the edges are, and wipes the glass in a planned pattern with a damp microfibre pad, spraying as it goes. On a normally dirty window the result is what most people would call clean.
Two things they won’t do, because these are what owners complain about.
Corners
A square robot can’t get fully into a square corner. Each of these has an edge mode and ECOVACS have put real work into it (corner brushes on the Lite, a scrubber that drops down at the frame on the W3 Omni), but if you notice a thin border you’ll still finish the corners by hand.
Neglected glass
These are for keeping windows clean, not rescuing them. ECOVACS say as much on the Lite’s own listing: for heavy stains or water marks, clean first. A window that hasn’t been touched in two years, or one crusted with salt spray, needs a proper wash before a robot takes over.
The outside of upstairs glass, and big fixed panes you’d otherwise pay someone to do. If every window you own is at ground level and easy to reach, a squeegee and ten minutes is the better tool.
The five compared

|---|---|---|---|---|---|---|---|
| ECOVACS WINBOT W1S | 5,300Pa2,800Pa while moving | No, works plugged in | Over 30 minutes | 3.5m robot cord plus 1.2m lead | 30 × 40cm | No | 1 year, ECOVACS |
| ECOVACS WINBOT Lite | 8,000Pa3,400Pa while moving | No, works plugged in | Over 30 minutes | 4.7m total | 25 × 25cm | No | 1 year, ECOVACS |

ECOVACS figures are from ECOVACS’ Australian product pages. TECHBEAR figures are from its retail listing, the only source there is. Where the two ECOVACS sources disagree we print both. Where a button shows a price, it’s the store’s price at the time shown, and the listing always has the current one.
The five robots
The W1S is the one to buy if you want flat glass done properly and don’t want to pay for a station. ECOVACS rate it at 5,300Pa of suction at its peak and 2,800Pa while it’s moving. That’s worth knowing, because some listings quote one figure and some the other, and comparing across the two makes a machine look weaker or stronger than it is.
It sprays in two directions as it goes, works out the size of the window before planning a route, and has three modes: fast, deep and spot. ECOVACS put a square metre at just under three minutes in fast mode.
On safety it has what you’d want before it goes near an upstairs window: a 3.3m safety rope, a gravity sensor, edge detection ECOVACS put at 0.02 seconds, and a backup battery that keeps it stuck to the glass for over 30 minutes if the power drops. It works plugged in, through a 3.5m robot cord and a 1.2m lead, so there needs to be a powerpoint within reach of every window.
Who it suits: a single-storey brick veneer with a couple of big sliding doors and a lounge window facing the street.
- 5,300Pa peak suction
- Stays on the glass over 30 minutes in a power cut
- Remote control and app
- Works plugged in, so a powerpoint has to be within reach
- No station, you handle the dirty pad
- The oldest navigation of the four ECOVACS machines
Australian warranty: 1 year, ECOVACS, as published · sold by ECOVACS Robotics, dispatched from Australia
This is the one we’d buy for a two-storey house, and the station is the reason. It holds a battery ECOVACS rate at 110 minutes, so the robot can work a balcony door or a bathroom window with no powerpoint nearby. It also combines the power cord and the safety rope into one 5.5m cable, which the station winds back in when you’re done. On an upstairs window that’s one cable over the sill instead of two.
ECOVACS list twelve stages of protection. The ones that matter upstairs: a safety cable rated to 100kg, a 1m tether at the base of the station, and a station that weighs 5.2kg and is held down by its own suction. It has five cleaning modes, including an edge mode, and a newer navigation generation than the W1S.
One figure to treat carefully. The retail listing title says 2,800Pa. ECOVACS’ Australian product page says 5,500Pa. Our guess is that 2,800Pa is the figure while moving, which is how ECOVACS rate the W1S, but they don’t say so for this model, so we print both. Our earlier window guide compared the 2,800Pa with the W1S’s 5,300Pa and called this machine weaker. That compared two different measurements, and we’ve dropped it.
Who it suits: a two-storey weatherboard with ten or more windows, some of them only reachable from a balcony.
- Works on battery, no powerpoint needed
- One combined power and safety cable
- The station stores the robot, cable and pads together
- You still take the dirty pad off by hand
- Its suction figure differs between the listing and ECOVACS’ page

The Lite is the smallest WINBOT we compare, and that’s the point of it. At 215mm square and 55mm thick it fits glass the others can’t: ECOVACS rate it for windows down to 25cm × 25cm, against 30cm × 40cm for the W1S and W2 PRO Omni. In a unit with narrow awning windows, or a house with small panes in a door, that difference decides it.
It’s newer than the W1S, with an edge mode among its cleaning modes, and brushes on all four corners to get closer to the frame. ECOVACS list 8,000Pa of peak suction and 3,400Pa while moving, both higher than the W1S. Our earlier window guide said ECOVACS published no suction figure for the Lite. They do, on their Australian product page, and this guide uses it.
The catch is size. It’s a smaller robot built for small panes, so on big panes the W1S suits better. It’s also newer here than the rest of the range.
Who it suits: an apartment or townhouse where most of the glass is narrow or broken into small panes.
- Fits panes down to 25cm × 25cm
- Higher published peak suction than the W1S
- Corner brushes and an edge mode
- Built for small panes rather than big ones
- Works plugged in, no station
- Newer to Australia than the others here

The W3 Omni is the top of ECOVACS’ WINBOT range. What sets it apart is the station: it washes the wiping pad for you in about a minute, with high-pressure jets and spinning scrubbers, so you never touch a dirty pad. On every other robot in this guide, you do.
ECOVACS give its peak suction as 10,000Pa on the W3 Omni’s shop page and 8,000Pa on its feature page, with 3,300Pa while moving. They also list a battery rated at 130 minutes and a scrubber that lowers at the frame and, they say, cleans to within 1.1mm of the edge. Like the W2 PRO Omni, it has a 5.5m combined power and safety cable, a safety cable rated to 100kg and a 1m tether at the base of the station.
Now the honest part. It’s new to Australia, and when we checked it had very little owner feedback of its own. Everything above is ECOVACS’ own specification. On paper it’s the best machine here; we just can’t point you to Australian owners who’ve lived with it yet.
It’s also big. The listing gives 48 × 40 × 48cm and 16.9kg for the item, and doesn’t say whether that weight includes packaging.
Who it suits: a house with a lot of floor-to-ceiling glass, much of it upstairs, where you’d happily pay to never handle a dirty pad again.
- Washes its own pad, you never touch it
- The longest battery here
- WIN-SLAM 5.0 navigation, against 3.0 or 4.0 on the others
- Very little owner feedback in Australia yet
- A big, heavy station to store

The TECHBEAR is the only robot from outside ECOVACS that made the cut. It’s sold as a “Window Cleaning Robot with Dual Water Spray”, and the listing’s details give the model as HCR-21. That matters, because a TECHBEAR remote-control model sits next to it in search results and didn’t make the cut. It’s sold by a third-party seller rather than the brand and dispatched from Australia, the listing states a 12-month warranty from TECHBEAR.
It’s more basic in the ways that matter upstairs. It’s corded, and the listing gives a 1.8-metre power cable, so plan on an extension lead for most windows. Its backup battery holds it on for about 20 minutes in a power cut, against over 30 for the ECOVACS machines. It sprays from both sides, has three wiping patterns, and comes with a remote and an app. There’s a safety rope the listing rates to 267lb, about 121kg.
What the listing doesn’t tell you: a suction figure, the smallest window it will do, or which plug is supplied. If the plug matters to you, and it should, check the listing photos or ask the seller before you buy.
Who it suits: ground-floor glass near a powerpoint, cleaned a few times a year, where an ECOVACS is more robot than the job needs.
- 12-month warranty stated on the listing
- Remote and app control
- Short 1.8m power cable
- About 20 minutes’ hold in a power cut
- No published suction, smallest window or plug type
Warranty: 12 months, TECHBEAR, as stated on the listing · sold by a third-party seller, dispatched from Australia
Can a robot clean the outside of an upstairs window?
Yes, and it’s the best reason to own one. You open the window, reach out, and put the robot on the outside of the glass. Suction holds it there. The safety rope runs back in through the opening and clips to something solid inside the room. Nobody goes up a ladder.
Whether that works on your house comes down to the window, not the robot.
You need an opening beside the glass. On a sliding window you open the slider and put the robot on the outside of the fixed pane. A fixed pane with no opening next to it can only be cleaned from the inside, by any robot.
A flyscreen or a security screen over the opening has to come off first. The robot and its rope both go through that gap. If the screen is fixed, the outside can’t be done from inside the room.
A window restrictor has to be released. In NSW, strata buildings must have devices that stop a window opening more than 12.5cm where the floor inside is 2m or more above the ground outside and the window is lower than 1.7m from that floor. The national building code sets the same 125mm limit for bedroom windows in new apartment buildings. A 12.5cm gap doesn’t leave room to reach out and put a robot on the glass safely. These devices are allowed to have a child-resistant release: use it, do the window, and lock it again before you walk away.
The rope needs a proper anchor. It only catches the robot if it’s clipped to something that won’t move. A curtain rod isn’t it.
Plug-in robots need a powerpoint within reach. That’s the W1S, the Lite and the TECHBEAR. The W2 PRO Omni and W3 Omni run on battery, which is why they’re the ones we’d pick for upstairs.
Someone still has to lean out to put the robot on and take it off. Do it with the window open wide and both hands free, not balanced on a chair.
Windows a robot won’t do
ECOVACS are unusually specific about this, and the same limits apply to any robot that works by suction.
- Louvres. Each blade is a separate strip of glass, far smaller than the smallest window any of these robots is rated for.
- Small panes. Under 30cm × 40cm for the W1S and W2 PRO Omni, under 25cm × 25cm for the Lite.
- Glass that isn’t flat and smooth. ECOVACS rule out curved or irregular glass, cracks, and glass with decals or stickers on it.
- Very low frames. The robot uses the frame to find the edge. ECOVACS give a minimum frame height of 3mm for the W1S, and 1mm for the Lite on its product page (its manual says 2mm).
- Condensation, oily film and extreme temperatures. ECOVACS’ Australian manual for the Lite says not below 0°C or above 40°C, not above 85% humidity, not on the outside in the rain, and outside only when the wind is calm.
Warranty and your rights
ECOVACS’ Australian warranty page gives 1 year as standard. When we read it, the only WINBOT on its longer list was the W1 PRO, which wasn’t available when we checked. So the four ECOVACS robots here are on 1 year, as published. The TECHBEAR listing states 12 months from TECHBEAR. Our robot warranty guide sets out the terms for more brands.
A warranty sits on top of your rights, not instead of them. Under the Australian Consumer Law, goods have to be of acceptable quality, fit for purpose and match their description, and those guarantees can outlast a manufacturer’s warranty. If the fault is major, you choose a refund or a replacement. Those rights are against the business that sold it to you, which for the ECOVACS robots is ECOVACS Robotics and for the TECHBEAR is the third-party seller.
This is also why we left out every listing that ships from overseas. Several ECOVACS models are only listed as imports from overseas, and those listings carry a warning that the manufacturer warranty may not apply.
General information, not legal advice.
The robots we checked and left out
We’d have liked ten. There aren’t ten we’d be comfortable putting our name to.
The rest didn’t make it. Most were imports shipping from overseas, whose listings warn that the manufacturer warranty may not apply. Some had listings that were unavailable or gone when we looked, one stated no warranty at all, and several had too few owner reviews to judge. If that changes, a model comes back into stock, or starts shipping from Australia with a warranty behind it, we’ll look again.

Questions people ask
Can a window cleaning robot clean the outside of an upstairs window?
Yes, if there’s an opening beside the glass. You reach out through the open window, put the robot on the outside, and clip its safety rope to something solid inside. The ECOVACS WINBOT W2 PRO Omni and W3 Omni suit this best because they run on battery and use one combined power and safety cable.
What stops the ECOVACS WINBOT W1S falling off the glass?
Suction first, then a 3.3m safety rope anchored inside, a gravity sensor, edge detection, and a backup battery that ECOVACS say holds it on for over 30 minutes if the power cuts. The rope is the part that catches it, so anchor it to something that can’t move, every time.
Does the ECOVACS WINBOT W2 PRO Omni need a powerpoint?
No. Its station holds a battery ECOVACS rate at 110 minutes, and it can also run plugged in. The W1S and Lite work plugged in, with a battery that only holds them on in a power cut.
Will the ECOVACS WINBOT Lite fit my small windows?
ECOVACS rate it for panes down to 25cm × 25cm, the smallest of the five we compare. The W1S and W2 PRO Omni need at least 30cm × 40cm. None of them will do louvres.
Is the TECHBEAR HCR-21 safe to use on an upstairs window?
It has a safety rope, fall sensors and a backup battery, but the listing gives about 20 minutes’ hold in a power cut and publishes no suction figure. We’d use it on ground-floor glass and buy an ECOVACS for upstairs.
Are the cheap window robots any good?
Some may be, but most we found had too few reviews to judge, shipped from overseas, or didn’t say who stood behind the warranty. This is a machine that hangs outside your window, so we only list ones where we can see the seller and the warranty.
How long does a window cleaning robot take per window?
ECOVACS put the W1S at just under three minutes per square metre in fast mode, and the W2 PRO Omni at about two. It isn’t quicker than doing it by hand. The point is that you aren’t the one doing it.
Is the ECOVACS WINBOT W2 PRO Omni or the W3 Omni better?
The W3 Omni washes its own pad in its station, runs longer on battery (ECOVACS rate it at 130 minutes against 110) and has a later version of ECOVACS’ navigation (WIN-SLAM 5.0 against 4.0). The W2 PRO Omni has the same 5.5m combined power and safety cable and the same 1-year Australian warranty, and you rinse the pad yourself. If you clean a lot of glass in one go, the self-washing pad is the difference. If you don’t, the W2 PRO Omni covers the same windows.
Is a window washing robot the same as a window cleaning robot?
Yes. Window washing robot, robot window washer and glass cleaning robot are other names for the same machines. They hold themselves on the glass with suction and wipe it in a planned pattern with a damp microfibre pad, spraying as they go. They keep clean glass clean: ECOVACS say to clean heavy stains or water marks first, so a neglected window still needs a proper wash before a robot takes over.
What about the WINBOT NEO MINI, HOBOT and MOVA window robots?
ECOVACS sell the NEO MINI on their Australian store as their most compact WINBOT, rated for panes down to 22 × 25cm. We haven’t compared it here yet. MOVA’s two window robots were on backorder on MOVA’s Australian store when we looked. For HOBOT, we couldn’t confirm who honours the warranty in Australia. When any of that changes, we’ll look again.
