N1
3 independent reviewsRead the findings →MOVA's compact, mains-powered window robot, small enough for narrow and divided panes. It cleans ordinary framed windows very well. It's unreliable on frameless glass, though, and leaves the corners to you.

Feedback
What reviewers found
There are three home tests. EFTM found it outstanding on framed windows, with no streaks, but it slipped on frameless pool-fence and shower glass. Macwelt agreed it cleans standard rectangular windows reliably, and warned that it doesn't always spot frameless edges. homeandsmart liked its frequent spraying and light weight but found the corners need doing by hand. All three found the mains cable and safety rope a nuisance to manage.

Cleaning result
Reviewers rate it highlyEFTM got streak-free framed windows, better than by hand, even on plain water, and Macwelt found standard rectangular panes cleaned reliably and completely. homeandsmart notes corners need a hand finish and an over-wet pad can streak.
Safety
Mixed resultshomeandsmart saw no wobbles on framed glass, but EFTM had two frameless failures, one caught by the rope, and Macwelt warns edge detection is unreliable there. MOVA says to fit the tether before every use MOVA.
Surfaces it suits
Mixed resultsThe tests back it on suitable framed panes, but frameless glass failed at EFTM. homeandsmart says it suits glass tilted up to 45 degrees, which clashes with MOVA's manual: that rules out anything more than 30 degrees from vertical MOVA.
Ease of use
Mixed resultsMacwelt had it running quickly and homeandsmart found the app intuitive. But all three found the mains cable and safety rope a nuisance, and EFTM disliked that it always starts in Quick mode and gives no low-water warning.
Noise
Reviewers rate it highlyEFTM measured a relatively quiet 65dB and homeandsmart 60 to 66dB, below MOVA's own figure, while Macwelt found it about as loud as its rivals.
Value
Reviewers rate it highlyMacwelt called its price very attractive for this kind of robot, and homeandsmart found the value balanced, with features not usually found at this price.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Great on ordinary framed windows
EFTM called it outstanding on traditional framed windows, better than they could manage by hand, with no streaks as long as the tank didn't run dry, even on plain water. Macwelt found it cleaned standard rectangular panes reliably and completely. homeandsmart puts the good results down to its frequent misting, but warns the pad must be only slightly damp or it leaves streaks, because there's no drying pass.
Frameless glass is risky
EFTM tried it on a glass pool fence: the corner sensors stopped it driving off the top, but near the bottom it slipped off and had to be rescued. On a partly frameless shower screen it dived off entirely and the safety rope caught it. Macwelt also found it didn't always recognise frameless edges and warns it could fall. The rope catches a fall but doesn't stop the robot missing an edge, so stick to the glass and frames the manual allows MOVA.
Corners and edges need a wipe
homeandsmart points out that the corner rollers have no brushes, so you'll be doing corners by hand. EFTM found it couldn't reach every edge perfectly and suggests running a damp sponge round the frame first. Sliding doors with insect screens also confused it, because its corner sensors didn't feel the edge before the body hit the screen. Plan on a quick finish round the frames.
Cable and rope to manage
The tests found the cable and rope awkward to manage, and they snagged at homeandsmart. Some reviewers skipped the tether on framed glass, but MOVA's manual says to fit it before every run MOVA. Give both leads room to move and tie the rope to something fixed. Allow time to put it on each pane and take it off again, and to rinse the cloth between dirty windows.
Modes, timings and the app
EFTM timed an 80 by 130cm window at just under 5 minutes in Quick mode, almost 9 in Deep and over 11 in Thorough. A 1 by 2 metre balcony door took Macwelt about 8 minutes in Quick mode. EFTM found it always starts in Quick mode, so you switch modes afterwards with the remote or app. Macwelt's unit needed a firmware update that failed on an iPhone but worked on an iPad.
Macwelt and homeandsmart reviewed it in German; EFTM tested it in Australia.
Our take
Should you buy the N1?
Best for: Ordinary framed windows with sockets nearby. Skip it if: Your windows are frameless.
The N1 may suit suitable framed panes with mains power and a secure tether point. Three tests support ordinary-window cleaning, but corners still need finishing and frameless glass caused falls. A W2S OMNI battery station means you don't need a socket nearby, but that doesn't prove it's safe on all frameless glass. Check pane limits and retrieval access before choosing.
The N1 is MOVA's entry-level window robot, below the T1 Station. It is a small square, about 6cm thick, so it fits smaller and divided panes and slips through railings and grilles. Two nozzles mist the glass as it goes and a microfibre pad wipes it in rows. It runs off the mains, with a small battery only to hold it on the glass if the power fails, and there is no station to wash the pad.
EFTM got streak-free framed windows, better than by hand, even on plain water, and Macwelt found standard rectangular panes cleaned reliably and completely. Frameless glass is where it goes wrong: EFTM had it slip off a glass pool fence and dive off a shower screen, saved by the rope, and Macwelt warns it does not always spot frameless edges. homeandsmart points out the corner rollers have no brushes, so corners need a wipe by hand, and an over-wet pad can streak. All three found the mains cable and safety rope a nuisance to manage, and EFTM disliked that it always starts in Quick mode with no low-water warning. Macwelt called the price very attractive for this kind of robot.
Before you buy
The questions people ask about this one
Does it work on frameless glass?
Not reliably. EFTM had it slip off a glass pool fence and dive off a shower screen, caught only by the rope. Macwelt found it didn't always recognise frameless edges. That makes it a poor pick for frameless glass. The tether catches a fall but doesn't fix the edge detection, so stick to the surfaces the manual allows MOVA.
What happens if the power cuts out?
MOVA says it keeps its grip for 30 minutes after a power cut, per the specifications, and EFTM notes the built-in battery is only there for that, not for cleaning. homeandsmart also mentions a small battery for the same job. Fit the tether before every run, indoors too MOVA.
Does it leave streaks or edges?
It cleans well, but it can streak and leave edges unfinished. EFTM saw no streaks while there was fluid in the tank. homeandsmart found an over-wet pad can streak, and that corners need doing by hand because the corner rollers have no brushes.
How long does one window take?
EFTM timed an 80 by 130cm window at about 5 minutes in Quick mode and over 11 minutes in Thorough mode. Macwelt needed about 8 minutes for a 1 by 2 metre balcony door. Add time to move it and rinse the pad.
Will it fit small windows?
It's 215mm square and 59mm thick and needs a pane of at least 30 by 45cm, per the specifications. Macwelt found it handy for smaller and divided windows. EFTM notes MOVA doesn't recommend it for panes under 30cm wide.
Does it need a special cleaning fluid?
No, but you can't use just anything. MOVA's manual says clean water or its official solution MOVA. EFTM got good results with water. Macwelt used a different cleaner, but that doesn't change what the manual says.
Alternatives
Other window-cleaning robots to compare.
WINBOT mini 2
Why consider it: The same compact size, with corner brushes that aim to reach the frame.
The compromise: It's also mains-powered and loud, and you stand beside it while it works.
WINBOT W2S OMNI
Why consider it: Its battery station frees it from the socket, and Trusted Reviews found it cleared dust and water marks inside and out.
The compromise: It's much bigger, needs panes of at least 30 by 40cm, and you still rinse the pad yourself.
R3
Why consider it: Its narrow body suits slim panes, and CHOICE found it made a real dent in dirty windows.
The compromise: Its round pads couldn't get properly into the corners, and it came off the glass once in testing.
