I hate cleaning windows, so when I had the opportunity to try a window cleaning robot I didn’t think about it for a second. The Dreame C1 promises to leave your windows spotless, everything controlled from its app. Let’s see how he did.

An elegant design


I have never used a robot window cleaner, but I have seen photos of a few and without a doubt the Dreame one is the most elegant of everyone. It has a cream-colored design, with a glossy finish on the top and a leather-effect handle so you can hold it safely when placing it on the glass.
The robot is completely square and has a weight of 1.6kg, quite reasonable for its size and the type of product it is. Next to the handle is the power button and next to it is the cap through which the cleaning solution is filled.
The most cumbersome thing are the cables since they are very long (necessary) and also have two transformers, one of them quite large. It is easy to connect, the cumbersome part comes when it comes to storing it, especially if you try to put it back in its box.
Setup and application
The start-up of the robot has no secret. Regarding the robot itself, we only have to fill the cleaning solution and place the cloth on the bottom, which is attached with Velcro. Then, as is usual in devices of this type, it is necessary to download an app to control it from the mobile phone and we must also connect it to a WiFi network.


The app is also quite simple and allows us to choose the cleaning mode, if we want it to do one or more passes and also choose between deep or quick cleaning. In the case of deep cleaning, the route that follows makes the passes closer together, so that they overlap each time. With fast mode it covers the entire glass, but makes more spaced passes. The cleaning modes are as follows:
- Complete: to clean entire windows.
- Borders– The robot focuses on cleaning the perimeter of the window.
- Area: allows us to manually select the cleaning area.
- Remote mode: allows us to control it with a crosshead.
Cleaning a window


The first thing is to turn on the robot from the physical button so that the fans that make it “stick” to the glass turn on. The suction is powerful and it immediately sticks to the surface, the problem is that it is quite noisy. It is understandable, but the worst thing is that the robot gives voice instructions at the same time as it cleans and the noise of the fans often makes it impossible to understand anything.

It has two straps that help it move across the surface, four brushes in the corners and the cleaning cloth that covers the entire perimeter.
But let’s get to what’s interesting, which is how he leaves the crystals. Just because I don’t like cleaning windows doesn’t mean I don’t appreciate when they’re spotless. I would like to say that the Dreame C1 makes them perfect, but the reality is very different.
After taking several passes at the window seen in the photos, both inside and out, you could see quite a few marks that he had left when passing, especially in the corners where the cloth does not reach.


One of the problems I see with the Dreame C1 is that it barely uses cleaning solution. Before starting it, I thought it would spray the cleaning solution from the bottom, but it does so through nozzles on the front and the amount that comes out each time is just a few droplets.
In the video you can see the problem: it sprays the product when it reaches the middle of the glass, so the cloth has little travel to spread it. In this way, marks are left from the liquid that has not been able to spread near the edges.
I also tested it in an apartment in the city and I was more satisfied here. I used it in two large windows with sliding windows that face the street (I don’t include photos so as not to dox me myself) and they get quite dirty. In order to clean them on the outside I have to take them down and they are quite heavy, so it is not very convenient to say the least. Although they weren’t perfect either, the result was much better than they were and the best thing: I I avoided having to disassemble them.
As for cleaning time, in all tests I used it with the deep cleaning mode and it was pretty fast. The large window, the one in the photos, measures 180 x 77 cm and cleaned each side in about 4 or 5 minutes. For the sliding windows (90 x 85 cm) it took even less.
Another point to keep in mind is that I dreamed only recommends using your own cleaning solution. In the box comes a 230ml bottle and is then sold in 1 liter bottles that cost 24.90 euros. The tank is 80 ml and according to Dreame it lasts for 60 minutes of cleaning, so it should last a long time.
Dreame C1, Xataka’s opinion


I really wanted to try a window cleaning robot and I admit that I had high expectations, perhaps that’s why my feeling is a little bittersweet. The Dreame C1 It has half reconciled me with cleaning the windows; It doesn’t leave them perfect, but there are cases in which it makes the task much more bearable.
It may be that with much larger glass the problem is minimized, but my feeling when I finished cleaning the window was that I would have done it faster, with less noise and it would have looked better. Where it has been useful to me is in hard-to-access windows: If the alternative is to take down windows weighing dozens of kilos or stretch from the fourth floor, the Dreame C1 is a good ally.
To the question of whether it is worth the outlay of money, I think that for 400 euros it is not, but taking into account that Its price has dropped to 250 euros, things change. If you have a large window that costs you a lot of time and effort to clean, it is a product to take into account.
