The best window-cleaning robots

We have robot vacuums, robot mopping machines, and robot pool cleaners, and it’s no surprise that the world of smart robot window cleaners is also following suit. While these window-cleaning devices are still in early phases and the technology isn’t quite as developed as, say, a Roomba, they can make taking care of large windows easier with an array of smart features, artificial intelligence (A.I.) movement, and unique cleaning technologies.

If you want to get an early start on this new tech, there are plenty of options on the market you can try. We’ve checked out current models and are ready to recommend some of the best, starting with the friendly Gladwell Gecko.

Note: Current window robots aren’t quite ready for cordless technology just yet, so these models will generally require a corded connection to an outlet. Many bots also have trouble with rounded edges and are generally made to work on glass surfaces that have right angles. There are also usually size requirements for the window to be big enough for them to move around, so windows smaller than around 15 inches can’t really host a cleaner bot — and they’re easier to clean by hand anyway. Some models may also have glass thickness requirements, but typical residential or commercial windows should be thick enough to handle them.

Gladwell Gecko

A great choice for home use and those who want an affordable but effective window bot, the Gecko is controlled by remote app and includes sensors to map out the window and avoid edges when necessary. The cleaning is a combination of suction and microfiber cloth, not unlike some hardwood floor cleaning bots, but with a safety rope attachment to prevent damage in case of an accidental fall.

There are a couple of different modes you can use based on your cleaning task, and LED indicators with manual controls if you don’t feel like using your app at the moment. We also like the user-friendly, compact design of the Gladwell Gecko, which is made for both indoor and outdoor use.

Wexbi Window Cleaning Robot

Wexbi’s window bot uses a brushless motor in combination with laser-based edge sensors and suction to clean especially smooth surfaces (for example, you can also use it for counters). It’s designed to do a quick maintenance round on a window and can clean nearly 11 square feet within three minutes. Like our other picks, it also has a safety system that will keep the bot attached to the window even if the power goes off. It comes with a 16-foot cord and a remote control — although you can also use an app if you prefer. The included pads are machine washable, too, so you don’t have to worry about disposable pads.

And yes, the Wexbi Window Cleaning Robot does indeed come with a gift, but it’s simply the nook brush and window cleaner included with the model, a nice addition, but not a make-or-break feature.

Mamibot W120

The square Mamibot model follows intelligent cleaning routes that work great for glass doors, long panes of glass windows, more. These types of surfaces may be especially common off decks, patios, or business entrances. The Mamibot can dry clean, wet clean with a solution, or do a quick pass for light cleaning. Whatever you need, it can keep windows looking good. There’s a built-in battery for quick emergency use (and keeping the unit attached if power fails).

Generally, the Mamibot W120 runs via cord, so you can’t rely on the battery for day-to-day use. Other emergency features include a safety rope and anti-falling sensors. At 65 dB, this bot is not exactly quiet — but it is easier on the ears than many alternatives.


The sleek Elfbot uses a vacuum and microfiber mat (free replacement pads included) to clean surfaces. It has three different modes to switch between based on the cleaning support that you need. A cleaning solution is available for wet cleans, but dry methods are also an option.

Like other competent models, the Elfbot includes a safety cord and suction features to keep it safely attached. An onboard battery can help keep suction going during power outages, protecting your bot from falls. Frame detection plus impact sensors to help guide the unit as it moves. The 16-foot extension cord is unusually long and suitable for larger windows and longer distances.

Ecovacs Winbot X

The Winbot X is completely cordless (rather than only having an emergency battery feature), unlike most of its competitors. It has a robust cleaning routine, with four different stages, inducing a “premium” squeegee stage, to ensure a thorough clean. Of course, standard offerings are included, like edge detection and safety ropes. The Ecovacs Winbot X doesn’t have a mobile app to serve as a control center, but it does come with a remote that allows you to adjust settings. 

Since we found that theEcovacs Winbot X has a background of connectivity issues and other bugs, we didn’t put it higher on our list.

When the Ecovacs Winbot X functions correctly and smoothly, it’s a wonderful investment. Due to its temperamental background, we’d recommend that you make sure the store you buy it from has a forgiving return policy so you won’t be out of luck if something goes wrong.

Smart window cleaners may sound like a pretty outlandish product or something straight from The Jetsons, but they’re available now, and they genuinely work. Instead of getting out there and getting dirty, not to mention putting yourself at risk, you can use remote controls and app assistance to get windows that look professionally cleaned. They’re pretty fun to use and extremely effective.
