Comparative | These robots clean the windows for you
Our expert has chosen the Ecovacs Winbot X as the best window cleaning robot of the three analyzed. The ease of use, the security measures it incorporates and its great autonomy make it superior to the rest.
In addition to cleaning floors, robots can become perfect allies for other household tasks. For example, lending a hand when leaving home windows (and other glass surfaces) without a trace of dirt. These window cleaning robots They are the protagonists of our comparison, in which we have selected three models from different manufacturers for sale on Amazon.
What models have we chosen?
The reality is that there are still not many manufacturers that are betting on this type of device. For this reason, we have chosen to choose three teams with similar characteristics on paper that promise to clean (almost) without assistance. Its about Ecovacs Winbot X (with an average score of 8.75 points), the Hobot 288 (7.75) and the Novohogar W-Clean900 (8).
During the tests, and taking into account the type of product in question, we have taken into account different variables common to all of them:
– Design: It doesn’t matter much whether they are pretty or not, but the quality of the build, their shock-resistant appearance, or their dimensions does.
– Cleaning: They usually have different cleaning modes, mops and recommendations for use. In this section, the finishing of the windows after use has been evaluated above all.
– Security: It is very important to bear in mind that, although their operation is autonomous and they have different safety measures to avoid accidents, it is always convenient to use them while you are present. Based on this idea, each device employs additional security measures to avoid unforeseen events as much as possible.
– Easy to use: Either controlling them from the device or from a remote control or a app mobile, we seek that anyone, even if they are not used to this type of robots, can use them without complications or help.
This is how we have tested them
All the robots participating in this comparison have faced, in the first place, a window with a high level of dirt: dust, fingerprints, watermarks … After verifying their performance in an extreme scenario like this, they have been used to clean all the glass doors and windows of the home after 15 days without touching them; a way of looking at the finish in a cleaning maintenance environment that also helps to test autonomy in the case of models with an internal battery.
After two months analyzing the performance of the products, the Winner Window Cleaning Robot has turned out to be the Ecovacs Winbot X. With the intermediate price in the comparison, it is easy to use, leaves a good finish on the crystals and transmits a lot of confidence thanks to its different security systems.
Ecovacs Winbot X: our choice
Size: mop 245 x 245 mm; minimum window 50 x 50 cm
Weight: 1,8 Kg
Working time: 50 minutes
Max height cleaning: 2,5 m
Noise: 74 db
Cleaning solution: 230 ml
Smart features: four-stage cleaning system, frameless window identification, memorize cleaning route, power-off protection, automatic return to exit point, alarm

This robot places special emphasis on safety so that there is no fall. To do this, the main unit has a strong absorption system that fixes it to the glass it is cleaning and is also accompanied by a suction cup – which works with batteries – that is connected in two ways: through an anchor cable and wirelessly with a 2.4 GHz connection. If it is not seated properly, it does not allow the system to start. It does not obstruct or limit the movements of the robot even if it is placed on the glass being cleaned, since it has an adjustable cable that adapts in real time to your needs. The mop is attached to the robot with Velcro fasteners and, for it to clean with guarantees, it has to be sprayed with a soapy solution (the package includes one of its own). After cleaning is complete, it can be washed in the washing machine.
Its operation is extremely simple and is managed from the robot itself – it has a button on its remote that acts as on / off and activates the automatic cleaning function – or through a remote control. Although in most cases the automatic mode is sufficient, this add-on also allows you to choose a deep cleaning mode that covers the surface of the window twice, once with vertical movements and another with horizontal movements. Although the results are not perfect, working with very dirty glass is surprising, as it removes dust and stains with great success.
The best: Its security measures give a lot of confidence and it is very easy to use.
Worst: Its price is high.
Conclution: An ideal robot to keep the windows of the house clean without much effort. It has autonomy for approximately 8 or 10 cleanings.
Stands out for its great value for money. Despite being the cheapest model in the comparison, the cleaning is on par with the competition. It can be used only with framed windows (even if they have vinyls) and it moves through the entire glass in a simple way and in three different ways, depending on the mode chosen on your remote control: in Z for wide windows, in N for long windows or a combination of both, which achieves best results. All the configuration is done from a remote control with specific buttons for these modes and an additional function, that of wringing, so that the crystals are completely dry and, thus, remove any marks that may have remained.
It works connected to the current and comes with an extension cable that is somewhat fair in terms of extension (1.5 meters that is added to the 2 meters of the transformer), as well as with two cleaning mops and a safety anchor similar to the one of the Ecovacs model, which seeks to avoid accidents due to power outages. In the improvements section, it is also worth mentioning an improvable finish and a fairly high noise level.
Despite its high price, the physical finish of the product does not convey the sensations it should, especially due to the materials used. It always works connected to the current, although it has an internal battery, with autonomy for about 20 minutes, which starts when it detects a power cut. This way, you make sure you don’t come off the glass.
With a powerful suction system that holds it well to the glass, even if they are rough (type partitions), it is controlled from a remote control or from a app installed in the smartphone. To achieve the best cleaning results, it is necessary to carry out two passes: a first dry and a wet one, for which two different cloths are used, included in the package and which differ very well due to their different colors. It is essential to be very careful with the amount of cleaner you put on the cloths – which are also much larger than those of the competition – because it is easy for stains to remain on the glass and make it difficult for the robot to move.
It stands out for its wide versatility, since it can be used with acid glass, beveled glass, vinyls, stickers, embossed glass, reflective glass, rough glass and laminated safety glass. This also includes those without a frame, since thanks to laser sensors it detects where the crystals end to turn.
