C1 Station
4 independent reviewsRead the findings →Dreame's window-cleaning robot with a carry-around battery station, so you don't need a socket by every window. It keeps regularly cleaned glass looking good. It's heavy and fairly loud, though, and won't shift stubborn marks.

What reviewers found
Four hands-on tests. TechRadar Netherlands and Vonguru used it on home windows, heise bestenlisten tested it against Ecovacs models, and Roboter-Forum did the same on panes including a terrace door and roof windows. All four found it good on light, everyday dirt and none saw it fall, but all say you stay involved. Edges and streaks split them: TechRadar Netherlands and heise bestenlisten praise how far the brushes reach, while Roboter-Forum found the pad stops short of the frame. heise bestenlisten also found it unpleasantly loud.

Cleaning result
Mixed resultsGood for upkeep, not neglect. TechRadar Netherlands and Vonguru got clean, mostly streak-free glass on regularly cleaned windows. heise bestenlisten saw a slight smeary film, and Roboter-Forum found the pad stopped short of the frame and spray dried as faint marks.
Safety
Mixed resultsNone of the four saw it fall, and Vonguru found the grip and rope reassuring. But heise bestenlisten had it run past frameless edges and stop until rescued, and TechRadar Netherlands stayed nervous about it swinging on its cable if it came off.
Surfaces it suits
Mixed resultsTechRadar Netherlands found it mostly held on bathroom tiles but got confused by floor-length windows. heise bestenlisten saw it overrun frameless and low-framed edges, and Roboter-Forum saw it push a shower-door seal aside and lose its bearings.
Ease of use
Mixed resultsTechRadar Netherlands and Vonguru liked not needing a socket and the automatic cable reel. But TechRadar Netherlands and Roboter-Forum found the station heavy to carry, and heise bestenlisten found the robot fiddly to slot in and a flap's pins came loose.
Noise
Mixed resultsheise bestenlisten measured nearly 70dB, with a high whistle that made the room unpleasant. Vonguru found it about average, and Roboter-Forum thought it a little louder than an Ecovacs but acceptable.
Value
Mixed resultsVonguru thinks it justifies its price for homes with big glass areas, but TechRadar Netherlands found the price hard to justify for an average home, and heise bestenlisten found a better-made, quieter Ecovacs cheaper.
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
Good for upkeep, not rescue jobs
On glass that was already fairly clean, TechRadar Netherlands got neat, often streak-free results, and Vonguru saw no visible marks on regularly cleaned bay windows. Glue residue stayed put for TechRadar Netherlands however often it went over it, and Roboter-Forum says dried-on spots and bird mess don't always come off. Vonguru needed a second pass or a cloth on very dirty glass. heise bestenlisten was less impressed: cleaner, but not streak-free, sometimes with a slightly greasy film. Wash neglected windows by hand once, then let it keep them that way.
The tests disagree on edges
Dreame fits brushes on all four sides to reach into the frame. TechRadar Netherlands says it gets deep into the corners, and heise bestenlisten found the brushes clean right to the outer edge, more effectively than the fixed scrubbers on Ecovacs' W3 and W2S OMNI. Roboter-Forum found the opposite: the pad doesn't reach the very edge, so the brushes loosen dirt that then isn't wiped away, leaving edges less clean than on Ecovacs. Roboter-Forum also saw spray land beyond the pad and dry as faint marks. heise bestenlisten warns the harder bristles could scratch delicate coatings. Keep a cloth handy for the edges.
Portable, but heavy and fiddly
The station is the reason to buy this version. TechRadar Netherlands calls it a carry case, power source and cable manager in one, and liked the button that winds the cable back in. Vonguru liked not having to run a cable to the nearest socket. The downside is weight: TechRadar Netherlands and Roboter-Forum both found it heavy to carry between windows. heise bestenlisten found the robot awkward to slot into the station, and the pins on the rear flap came loose on the third opening.
Noise is intrusive in one test
heise bestenlisten put it at nearly 70dB, above Dreame's own figure, and says a high-pitched whistle from the suction unit made staying in the room unpleasant. It rates it louder than most window robots. The others were less bothered: Roboter-Forum found it a little louder than an Ecovacs but acceptable, and Vonguru called the noise about average, like a vacuum cleaner on a moderate setting. If whining noises get to you, bear that in mind. Dreame's instructions also require supervision while it runs, per Dreame.
Frameless edges and floor-length glass
On frameless or low-framed glass, heise bestenlisten saw it occasionally drive over the edge, lose suction and stop with an error until rescued by hand. Roboter-Forum saw it push a shower-door seal aside and lose its bearings. On windows running down to the floor, TechRadar Netherlands found it sometimes treated the floor as an obstacle and stopped. When grip gets marginal, it raises suction, then stops and beeps, per Roboter-Forum. None of the four testers saw it fall.
This covers the C1 Station bundle. The C1 sold without the station has no portable power station, so the portability findings don't apply to it. TechRadar's review is from its Dutch edition, heise's and Roboter-Forum's are in German, and Vonguru's is in French. heise's test unit was supplied by Dreame.
Our take
Should you buy the C1 Station?
Best for: Large windows or glass doors far from convenient sockets. Skip it if: You need to remove stubborn marks from long-neglected glass.
The C1 Station may suit large, regularly cleaned panes far from sockets if you can carry the 7.6kg kit and accept manual pad washing, edge finishing and noise. It is less convincing on stubborn marks, and edge handling differed between tests. Stay with it during use as Dreame instructs. The W3 OMNI adds pad washing; the W2S OMNI has a battery station but still needs manual pad care.
The C1 Station is Dreame's first window cleaner, bundled with a station that powers it, anchors its safety line and winds the cable back in, so you can carry the whole kit from window to window. The robot is the same one sold on its own as the C1; the station adds a battery Dreame rates at about three hours and a fall-prevention lock. It sucks itself onto the glass, sprays water ahead of a microfibre pad, and has small brushes on all four sides meant to reach into the frame.
The trade-off is weight and fuss. Station and robot together weigh 7.6kg, it won't take panes smaller than 30 by 40cm, and you still move it between panes, wet the pad and wipe off the last marks. It suits homes with lots of large, tall or hard-to-reach glass. With a handful of ordinary windows, the time it saves is small.
Before you buy
The questions people ask about this one
Does it leave streaks or edges?
On regularly cleaned glass, TechRadar Netherlands and Vonguru got clean, mostly streak-free results. heise bestenlisten found a slight film and suggests drying the glass by hand straight after. Roboter-Forum saw faint spray marks and edges the pad didn't reach. Plan on a quick wipe round the frame.
Does it work on frameless glass?
With care. heise bestenlisten saw it occasionally run over the edge of frameless or low-framed glass, lose suction and stop until rescued, though it didn't fall. Roboter-Forum lists frameless glass as a weak point after it pushed a shower-door seal aside. Keep the safety line attached and stay nearby.
What happens if it loses grip?
It stops and warns you. Roboter-Forum saw it raise suction first, then stop, flash red and beep, and TechRadar Netherlands saw it report too little suction on bathroom tiles while staying put. If the battery runs low mid-clean, heise bestenlisten says suction keeps it on the glass. A safety rope adds backup, per the specifications.
Can it do outside windows on an upper floor?
Only if the pane and the setup meet Dreame's instructions. The manual requires a strong indoor tether anchor, suitable weather and supervision, per Dreame. The claimed 140kg cord strength isn't a guarantee against a fall. A reviewer tied it to a table leg, but that doesn't make any other table a safe anchor.
How long does one window take?
Roboter-Forum timed about six and a half minutes for one side of a terrace door. Add the time to attach it, wet the pad and move it. TechRadar Netherlands found the time saved disappointing in an average home, and Vonguru says its value drops if you only have a few standard windows.
C1 or C1 Station?
Same robot. The Station adds a battery rated at 180 minutes and a fall-prevention lock, per the specifications. Without it, the plain C1 needs a socket nearby. TechRadar Netherlands rates the station's portability as its biggest strength.
Alternatives
Other window-cleaning robots to compare.
WINBOT W2S OMNI
Why consider it: Its battery station also frees you from sockets, and three tests found it cleans everyday dirt well and gets closer to the edges than most.
The compromise: Corners still aren't perfect, and you move it between panes and wash the pad yourself.
WINBOT W3 OMNI
Why consider it: Its station washes the cleaning pad for you, which takes the grottiest chore out of window robots.
The compromise: It's still slow to move between panes, and one tester found streaks in corners and poor edge cleaning.
S7 Pro
Why consider it: Two scrubbing pads, and TechRadar found it spot on at detecting frameless edges.
The compromise: It's mains-only, and both tests found streaks on dirtier glass.
