How do robotic window cleaners work?
Before we get onto the robot (keep scrolling is that’s what you want) let’s have a look at how they work. The best robotic window cleaners use motorized suction to attach to a window with small wheels that help it to glide from one side of the window to another. The soft washable pads will then clean any dirt and systematically wash the entire window.
The best will be simple and easy to operate, you will just need to add a cleaning solution, attach to the window, kick back and relax. the cleaning robots are usually connected to a power supply for the duration of the cleaning cycles.
While cleaning surfaces, they use sensors to detect obstacles and window frames. Once the window cleaner has finished the job, it will alert you that the window is complete and you can move on to the next one before getting back to your relaxing, and they beautifully get the job done.
Do window cleaning robots actually work?
As with most window cleaning devices, the results won’t always be as good as you may like, simply down to the fact they do not have eyes. So if you are expecting a robot to do a job as good as you can do yourself, you may be disappointed.
However, that said, if you have lots of windows in your house they will save you a lot of time. You can attach it, let it do its thing while you do yours and when it has finished, move it to the next one. You may need a slight manual touch-up in the corners, but it definitely removes a lot of the work.
The other time they are really good is for the outside of tall windows and anything above the first floor. The safety aspect alone makes them great – just don’t forget to attach the safety cord!
You can learn more about the robots in our guide a bit further down, but for now, let’s give you what you came here for, the best of the best …

1. Hobot 2s Window Cleaning Robot
Let’s kick this list of the best window cleaning robots off with my #1 recommendation and the one I use myself, the Hobot 2s. You can see my full review on YouTube, but to sum it up, this is as good as you’re going to get, but also the most expensive.
The ultrasonic water spray system creates an ultra-fine mist that gets all the dirt in the nooks and crannies, while the strong suction and ascending power keep it in place.
The Hobot 2s can work on multi-surface, including rough surfaces, and has advanced edge detecting technology and edge leakage sensors to detect if the air is escaping around the window seal or edge of a frameless window.
The intelligent route planning will ensure the most efficient cleaning path and combined with the extended cleaning cloth means that this robot can deep clean into corners, reaching 80% corner coverage as opposed to the 20% of other brands leaving your glass clean.
With convenient smartphone and remote control options, a long power cord, and a 4.5-meter safety rope, the Hobot 2s is super easy to set up and use. I even love the fun (but admittedly quite pointless) feature of being able to customize the voice alerts. You could record yourself or even download suitable movie quotes!
One of the only drawbacks is I thought they could include more than 3 machine washable pads. I find that after a couple of windows, they need replacing, so three isn’t really enough to do completely my home (which isn’t exactly large) to the best quality in one session.
Anyway. HOBOT’s wide range of features and options make it an excellent choice for anyone looking for a robotic window cleaner who wants an extremely thorough cleaning job done, but it does come at a price.
- Be sure to read my full Hobot 2s review to see why it is the best robot window cleaner.
- Best in class performance
- Ai cleaning technology
- Smartphone app with smart tracking mode
- Dual water tanks
- Great for large windows
- Works on multiple surfaces

One of the standout features of this automated window washing device is the ultrasonic cleaning solution spray nozzle to ensure the robot doesn’t leave streaks. This allows the device to handle much dirtier windows than some of the cheaper models and is capable of cleaning a variety of glass surfaces.
Designed for automatic window cleaning, Hobot 298 features advanced artificial intelligence and convenient app controls that can be accessed via smartphone or the included remote control. Hobot 298 comes with a long power cord and safety rope which acts as an additional safety feature if the powerful anti drop technology fails.

4. ECOVACS WINBOT 880 Robotic window Cleaner
The Ecovacs Winbot 880 attaches to your glass using a powerful suction force cleaning dirt and dust using a 5-layer decontaminate microfiber cleaning pad and high-elastic squeegees.
Before going to work, Ecovacs Winbot 880 uses Win slam 2.0 technology. A path planning technology that detects the shape of your glass surfaces and identifies the best cleaning route in a fast, comprehensive, and economical way.
The Ecovacs Winbot 880 then follows a thorough 4-stage cleaning process. First, it sprays a cleaning solution on the front of the cleaning pad to wipe the window and loosen dirt particles.
After that, a squeegee passes over, removing dirt from the window. Then another squeegee still goes over to remove any stubborn dirt. Lastly, the back of the cleaning pad wipes the window dry erasing any greasy tracks and leaving you with clean windows.
Finally, I want to mention the well-designed safety features. The Ecovacs Winbot 880 packs a 30-minute backup battery, 2800Pa suction power, a strong safety rope to prevent the machine falling, and a load-bearing suction cup, all work together to ensure safety during cleaning.

5. HOBOT 388
The HOBOT 388 is a dual-wheel robotic window cleaner complete with an onboard water tank that can be used with the HOBOT cleaning fluid or just water.
Its two specially-designed cleaning wheels are wrapped in microfibre cloths to offer a 2-stage cleaning process that can be controlled via a smartphone app or the intuitive remote control.
As the window cleaning robot gradually moves across the glass, it first passes by to clean with dry cleaning pads, the soft fabric of the cleaning pads absorbs dust particles and the vacuum sucks up any loose dust.
The second stage is cleaning with the patented ultrasonic water spray nozzle. This system can nebulize cleaning solution to 15-micrometer mists before the second wheel thoroughly wipes the surface of your windows leaving a satisfying shine at a decent cleaning speed.
A high-volume centrifugal pump means that this window cleaner packs a lot of suction and can be used on multiple surfaces including mirrors and tiles. It’s great for bathroom walls, even mosaics can be conquered.
Overall this is a very impressive upgrade on the HOBOT 188 and 198 and the first time we have seen a water tank on such a small robot.

7. Mamibot W200 Wireless Window Cleaner Robot
Next on our list of the best robotic window cleaners is the battery-powered window cleaner Mamibot W200. It is an upgrade of the hugely popular Mamibot W120 which is a less-expensive robotic window cleaner that can still be considered.
The Mamibot W200 is a high-end window cleaning robot that utilizes intelligent edge detection technology and a powerful suction fan function to provide double edge protection for frameless glass cleaning. With 4 sensors, the W200 is able to automatically recognize window frames and adapt its direction in time to optimize its cleaning patterns, making it capable of cleaning various kinds of window surfaces, including framed, frameless, colored, decaled glass or French windows.
The W200 is easy to operate; with just one push of a button, the AI algorithm plans the most intelligent cleaning path. The window washer can be controlled with remote control within a maximum of 20 meters as the crow flies, and when the cleaning is complete, it will automatically return to the starting point.
However, the stand-out feature is that it is the first (and only) wireless robotic window cleaner, meaning it is designed to be more convenient to use. With a running time of up to 90 minutes after a full charge and a backup battery to prevent falling for an additional 30 mins.
The downside of this means a lot of charging for larger homes.
Another feature I love is the inclusion of a suction cup to attach the high-strength safety cord too. All robot window cleaners come with a safety cable, but having a place to attach them can be a bit of a problem!
Overall, this can be a great choice for busy people who will love its wireless convenience. It is a great mid-high price range choice suitable for smaller homes.
- Great value and a 5-year guarantee
- App commands generate an immediate response from the device
- Dynamic applications, capable of cleaning skylights
- Double functions as a robotic mop
- Cleaning or washing fluid is not including with purchase of the device

Robotic window cleaner buyer’s guide
There are a few things that you should consider when picking the best window cleaning robot for you. Most of the product’s traits will depend on the amount of window space that you need to be cleaned at one time. Consumers can also choose whether they want a window washing robot that is completely automated or one that includes a remote control.
Battery Life
You won’t find many pure battery-powered window cleaners because they mostly work with long power cables connected to a power switch. However, they usually come with embedded UPS for backup in case of a power failure.
The majority of robotic window cleaners have a brief battery life, which usually adds up to around ten windows in a single charge. Some smart window cleaning gadgets will maintain a battery life of fewer than fifteen minutes while others will last over thirty minutes.
Safety ropes and/or Back-up Battery
While some robots will have a backup battery, which is good, all should have a safety cord. These are designed to stop the robot falling to the ground should it loose suction on the window. Super necessary if you have tall windows.
Cleaning Patterns
The more advanced robotic window cleaners have different cleaning modes and smart cleaning patterns. It’s a nice feature to have, but not essential as they will all cover the surface eventually.
Replacement Pad Cost
Even the best robotic window cleaners will occasionally require the replacement of individual parts. In this case, the most common parts that need to be replaced are the cleaning pads.
Shape of Windows
Some robot window cleaners will fall when used in a frameless window while others have no problem remaining attached. Also, some models may be OK with windows that are not rectangular, but most will struggle. Be sure to know what type of windows you’ll need cleaning before clicking buy.
Noise Level
Most robotic window cleaners will make some noise. When choosing a window washing device, consider if noise is an issue in your environment. If loud or distracting sounds are going to cause a problem in the space being used by the device, robotic window cleaners with lower noise levels (under 60db) should be a priority.
App Connectivity
The latest window washing robots will usually come with an app that can be used on a smartphone to assist in controlling the device. This app is a very convenient feature for users who are generally busy while conducting household chores.
Robot vs magnetic window cleaners
A magnetic window cleaner is a device that uses magnets to attach to the window and then be pulled across the window to clean it. The magnets are very strong and hold the unit in place while you clean. The problem with these cleaners is that they can be difficult to use and can damage your windows. They also don’t work well on all window surfaces.
Robot window cleaners, on the other hand, use vacuum suction to attach to the window and wheels to move across the glass. These cleaners are much easier to use and there is less risk damage your windows. The other big benefit is reaching the high places that you would need a ladder for.
While they are two different window cleaning solutions, my preference would certainly be a robot as it’s just easier.
Ongoing maintenance
These robots have several moving parts. However, they’re much easier to take care of than you might think. By following a few basic tips and guidelines, you can effectively maintain your automatic window cleaner.
- Many models won’t function in low temperatures; therefore they’re not best to use in cold areas or during the winter months. When using the machine in warmer temperatures, be sure that you avoid humidity because it can damage the automated window washer.
- Some robotic window cleaners are explicitly meant for windows that have straight lines or edges. A model that is designed for straight lines or edges won’t function properly on surfaces that aren’t straight.
- Cleaning pads should be changed often to ensure that they are being used effectively. They should be washed after each use or replaced with new ones.
- Don’t forget to also clean the wheels or tracks as they will leave marks if not clean
- Windows should be cleaned weekly to maintain a certain level of cleanliness and ensure that the robotic window washer doesn’t need to take on more than it can handle.
