Why Use a Window Cleaning Robot
We’re on the cusp of a Jetson-like era where a battalion of mechanical servants is available to do tedious household tasks. There are robotic vacuum cleaners that can get our floors spic and span without us having to lift a finger.
Robotic pool cleaners can magically transform a pool that was previously unbelievably filthy into an immaculate one. There are even robotic lawn mowers that save us from pushing a hydrocarbon-spewing behemoth in 90-degree heat.
Game Changer for Commercial Businesses
The latest labor-saving device on the block is the window cleaning robot. This invention has been a game-changer for commercial businesses everywhere. No longer must an individual risk their life by traveling hundreds of feet upwards in a dangerous basket just so a company can have windows that are sparkling clean. All a maintenance person needs to do is to set up a handy dandy window cleaning machine on the side of a skyscraper and let the bot do the rest.
Soon, the device will scour the accumulated gunk from every window in the building. Commercial window cleaning robots are technological marvels jam-packed with impressive features. For example, if wind gusts make operation unsafe, the bot will shut down until meteorological conditions are more favorable.
Benefits for Residential Users
However, this revolutionary advance in technology also offers enormous benefits for residential users. These tiny yet highly intelligent apparatuses have cutting-edge electronic sensors that can plot the best path on every window of a home so that the glass can be cleaned in the most efficient way possible.
Window cleaning bots are fantastic time savers. Even using one for a short time can prove to be an eye-opening experience when you realize how many hours they can trim off your household cleaning schedule.
They’re an excellent alternative to ladders and manual operation of chemical sprayers, which can be hazardous to your health. By purchasing one, you’ll have more time to devote to projects that are far more meaningful than tedious household chores. For this reason alone, it’s well worth investing in one of these devices.
Window Cleaning Robots 2023: Rating and Reviews of the Top Performing Options
The GoodWith some window cleaning bots, you need to spray lots of expensive detergent on the cleaning pads in order for the unit to work. Not so with the HOBOT. It has a reservoir that efficiently applies a light mist of cleaning solution.The combination of the proprietary ingredients of the detergent and highly effective cleaning wheels gets your windows sparkling clean — even when the solution is used sparingly.
The Not-So-GoodThe HOBOT is only for rectangular windows, and not ones with rounded edges. You only can use the robot on sunny, low humidity days because glass needs to be completely dry in order for it to be effective.
The HOBOT does a bangup job of cleaning most areas. However, it won’t be able to entirely clean small areas at the top and bottom corners, and you’ll still have to manually clean frames and tracks.
What Customers SayCustomers who want to protect their investment are ecstatic to learn that the chances of their bot tumbling to the ground are reduced to practically zero by these three things:
- A pressure change detection system that forces the robot to turn around when it reaches the edge of a frameless window
- A battery backup that allows the bot to function for 20 minutes after an unexpected power shut off
- A alarm that sounds when the unit switches to battery backup
The GoodThe automatic ultrasonic spray nozzle helps break up tough build-up and grime, helping the machine produce a streak-free clean with ease. Intelligent navigation technology automatically chooses the most optimal cleaning path for even more efficient cleaning. Key precautionary features include a safety rope, edge detection and avoidance, and a battery backup in the event of power failure. This helps protect your flooring, as well as your investment.
The Not-So-GoodWhile the automatic sprayer is helpful at breaking up grime, it’s not a perfect system and may struggle a bit with excessive buildup. Included smartphone integration and app support is a welcomed feature and addition, but the app itself is not as intuitive as it could be. Intelligent navigation is another appreciated feature, but it may struggle at times with certain functions.
What Customers SayPeople largely love how the device cleans, particularly on larger windows and even oddly-shaped ones. They also enjoy the variety of safety features and precautions that have been integrated, increasing confidence in their purchase. As always, people can’t get over the burden that’s eased by not needing to manually clean.
That said, some users have mentioned that on dirtier windows or those with excessive buildup, a bit of manual cleaning may be needed to help assist the robot. There can also be issues managing to successfully contact support for assistance.
The GoodIt’s incredibly easy to set up and use, only taking a single button to get started. However, the app provides a surprising amount of responsiveness and control. Not only are there different preset modes, but you can manually control movement.
The suction also works exceptionally well, shown to withstand over 15lbs of vertical weight. But that doesn’t mean it’s overly loud. In fact, it boasts a noise level under 65db.
The Not-So-GoodWhile it offers a unique combination of advanced features and mid-tier price, it does lack any of the bells and whistles of more advanced tech. For example, many premier robotic cleaners now come with automatic sprayers.
If you apply too much or too little of your cleaning solution to the window, it can sometimes leave a bit of streaking. That said, this problem resolves itself after a bit of trial and error.
What Customers SayCustomers found it fantastic for larger windows, thanks to the advanced route planning and responsive movement. Some suggested pre-washing windows before running the machine for the first time all season to save a significant amount of life on the microfiber pads.
Others noted further issues with the amount of cleaning solution used. If too much is applied, it can’t move effectively and leaves streaks. If not enough, it won’t clean much and can squeak. However, most were able to find their ideal range.
Mamibot W120Price: AverageThe Mamibot W120 is the immediate step down from the W120-T. As such, it has nearly all the same features but at a lower price. Likely the largest functional difference between the two models is the specialized wet and dry pads on the W120.
Aside from that, the W120 is much lighter than the newer model. Unfortunately, the Mamibot W120 has been discontinued by the manufacturer, so get them while they last!
The GoodThe HOBOT-2S uses high-frequency ultrasound technology to transform water into tiny particles that not only powers away dirt and debris, but creates an anti-static film on glass surfaces that repels dust.
What’s more, unlike some other bots, the 2S cleans more than windows—it also scrubs away filth from bathroom mirrors, tile walls, and large mirrored cupboards. This makes it a consummate multitasker that’s an invaluable addition to your house-cleaning arsenal.
The Not-So-GoodBecause humans are faster at window cleaners than robots, it’ll take longer for this droid to complete a job than if you did it yourself. You can’t leave the 2S unattended because there’s no way for it to jump from one window to another. This means that after it cleans a window, you’ll need to get up and manually move it.
What Customers SayCustomers with tall windows love how the 2S saves them from having to climb a ladder to get the job done. This ensures they won’t have to risk life and limb in order to have radiantly clean glass surfaces.
Other buyers appreciate that the 2S has a backup battery that lets it continue cleaning for up to 20 minutes if the power ever goes out. That way, it’ll adhere to windows instead of tumbling to the ground, saving their unit from getting destroyed.
The GoodDespite not being made from cheap plastics, and therefore weighing over two-and-a-half pounds, it adheres remarkably well to all sorts of window surfaces. The all-new centrifugal pump design allows the system to efficiently adjust suction as needed.
Another massive improvement of the 298 over earlier models is its Bluetooth enabled app. Not only does it allow you to start, stop, and select from the preset cleaning modes, but you can also alter the rate and strength of the sprayer, and even control where it goes directly.
The Not-So-GoodProbably the main drawback is the cost. It’s easily one of the most expensive automatic window cleaning robots around. That said, you do get what you pay for, and it’s got the features to back it up.
The included 13ft extension cable is nice, but you’ll still likely need another extension cable unless you want to constantly find a socket. The sprayer location also seems a bit odd, being off-center.
What Customers SayCustomers love how quick and easy it is to set up and use, with no assembly needed other than attaching the pad and plugging it in. Many also loved that while it’s designed for use with their formulated cleaning solution, you can also use pure water instead. When tackling tough, built-up grime, many users found spraying before-hand helped the automatic sprayer do its job more effectively. Similarly, some customers have found that without an adequate cleaning solution, it’s possible to leave minor streaks.
- HOBOT-198Price: High
The Hobot 198 has less functionality than the 298, but it’s still an extremely effective device. For starters, their designs are quite distinct. Instead of a square design powered by tracks, the Hobot 198 uses dual spinning microfiber pads to navigate around the window. This does help ensure a streak-free finish. It also lacks the automated sprayer and cutting-edge AI-controlled routes of the premier model. However, the 198 is still a high-end window cleaning robot and effectively cleans many types of surfaces.
The GoodThe W200 has the longest run time of almost any other winbot—up to 100 minutes on a single charge. At only eight centimeters thick, it’s one of the slimmest window-cleaning robots on the market.
It’s able to clean a wide variety of windows, including framed, frameless, colored, decaled glass, and French windows. Four sensors detect the edges of frameless panes, and when they do, automatically boost power to protect the unit from falling off.
The Not-So-GoodCustomers who’ve lost the remote have had a difficult time getting a replacement. This is a bit of a problem, as the unit is unusable without it. Fortunately, these users were eventually able to get new remote controls, but it took forever for the manufacturer to respond to this issue.
What Customers SayMothers of young children who don’t have a lot of time love how the W200 cleans dirty windows for them so they don’t have to. Other users are ecstatic about how easy the unit is to operate—especially with a remote. This makes window cleaning virtually effortless, which is something they wholeheartedly appreciate.
Your Comprehensive Guide To Window Cleaning Robots
Just How Well Do Automated Window Robots Work
The Magic of Winbots
Many people are amazed when they see their first window cleaning robot, often known simply as a Winbot. It seems like something straight out of science fiction, a large robot magically floating across the glass.
Despite their quite magical aura, the science behind how they work is pretty straightforward. These machines are held up one of two ways, either a powerful vacuum creates enough suction to hold the robot to the glass, or a specialized magnet is placed on the opposite side of the glass.
Magnets vs. Suction
While there is the occasional device that utilizes a hybrid of these, for the most part, it’s one or the other. Magnets were far more common than suction-based tech in the early days of Winbots. However, as the efficiency of motors and vacuums has improved, the magnetic connection is becoming less used.
Despite this, one major advantage of magnetic-based models is that you never have to worry about your machine falling due to a loss of suction or disconnecting from the power. That said, a significant reason why they’re becoming less popular is that attaching a magnet on the other side of the glass isn’t always a viable option, making them far less versatile.
Suction-based cleaners are growing much more common in the last couple of years. It’s not hard to understand why when you see just how powerful this technology has become. They can be used virtually anywhere, with many models even boasting the ability to work on skylights. This does mean that some are quite a bit louder than their magnetic counterparts. However, high-end devices do a fantastic job of mitigating the noise level. Another potential downside is the need to attach a safety rope to ensure no accidents. While for many, this isn’t much of an issue, it’s a definite downside compared to magnetic robots.
These days the vast majority of high-quality window cleaning robots use suction over magnets. Despite the downsides, they tend to be relatively faster moving, leave fewer streaks, and work on a wider variety of surfaces.
Although you should always check the specifications of your specific device before using it on an uneven surface. Additionally, as backup battery technology improves, it has dramatically reduced the risk of vacuum robots falling.
How They Work
Regardless of how they’re attached to the glass, the robots travel using a set of wheels or tracks. Other types of Winbots may move in a circular motion via the spinning of dual microfiber pads. Window cleaning robots are always equipped with microfiber pads to efficiently clean the glass without leaving any streaks.
While higher-end models will sport more advanced features, such as automated sprayers and advanced route planning, all window cleaning robots function by the set of principles. For the most part, how well they work depends on how well you do your research and follow the guidelines when using it.
So if you’ve decided to buy an automated window cleaner, let’s break down the most important things to keep your eyes on!
What Makes A High-Quality Window Robot
What makes a given window cleaning robot good or bad will be greatly dependent on what your needs are. Before making any purchases, you have to ask yourself what sort of windows need to be cleaned, how many there are, and how often they need to be done.
As you can imagine, these answers are going to vary significantly between the average homeowner and a small business owner, for example. As such, what would be considered a good robot for one person may not nearly do the needed job for someone else. Very few window cleaning robots can realistically do it all.
Size, Shape, and Weight
The dimensions of your potential winbot is always an excellent place to start. Its size is going to directly dictate the windows it can clean. If you need a lot of small windows cleaned, it doesn’t make nearly as much sense to get a giant robot as it does for someone with massive windows all around their house.
Instead, those people should opt for a smaller device that can get their needed job done right. The shape of your robot is also critical. For instance, dual spinning models cannot get into corners effectively but are fantastic for circular windows.
Weight is an often overlooked part of the dimensions. After all, if it’s being sold, the suction created can handle the weight. However, if you live in an older house with thin glass, the glass might not! While many newer models don’t have this drawback, it’s always better to check the specifications for a minimum glass thickness before making a huge mistake.
Quality of the Motor
The motor is likely the most impactful part of any automated window cleaner. Not only does the quality directly determine the suction power, but also the speed of movement, and even how loud it is. More suction power and speed are always preferable, especially for those worried about it falling or for those with a lot of windows to clean on a regular basis.
Top-quality machines are capable of providing incredible suction while remaining relatively quiet. That said, mid-tier robots tend to be much louder, which is only a problem if you plan on using it while relaxing.
Attention To Safety
A window cleaning robot of any level is a hefty investment, which makes the focus on safety all the more critical. As such, most users appreciate brands that implement extra features. For example, the majority of vacuum powered cleaning robots now have a backup battery used to keep the machine attached if the power somehow becomes disconnected.
An often overlooked safety feature is the indicators used to alert people of issues. While the majority of devices still rely on simple beeping and LEDs, some newer models have begun using voice alerts to relay important information. This significantly reduces the chances of a critical failure. Just think of how many times you zoned out and didn’t notice something beeping!
AI Technology
The AI used in any robot window cleaner impacts how well it cleans. Simpler machines will use random routes that, with enough time, clean everything. Most advanced models now use AI-powered routes that use a set of sensors and circuitry to track where it’s been and where it needs to go next. The cutting edge models have begun to build on this AI, crafting multi-step cleaning processes for leaving a sparkling finish. The bottom line is, the better the tech powering your robot, the happier you’ll be with how it works.
Advanced Features
There’s been a ton of innovation in the window cleaning robot market over the last couple of years. One of the new features becoming increasingly requested is automated sprayers. Instead of needing to pre-spray each window as you go, these robots ensure the right distribution every time. Similarly, apps have become commonplace, offering a greater sense of control over the process.
Other Things To Consider
- Power cable length – You should always keep in mind how long the cable is and where you’re going to be using it most. Be sure to consider where the outlets are, and if you’re going to want or need an extension cable.
- Replacement pad costs – While most of the microfiber pads sold with automated window cleaners are machine washable, they won’t last forever. You should compare the price of different brands if you’re stuck between a couple of options. Either way, to extend the life of your pads, wash them after each use.
FAQ
How useful a window cleaning robot is, really comes down to why you need it. For example, any small business with lots of large windows should seriously consider the investment. It’s a small expense to ensure their business is always giving off the best impression possible, without wasting workers time.
By the same token, any homeowner who has a lot of large or inaccessible windows who want them to be clean would also find a cleaning robot to be quite helpful. However, if you only have a few small, reachable windows to do at your house. It may not be an essential purchase.
As mentioned above, we believe two primary groups of people should strongly consider buying an automated window cleaner:
- Business owners will get a ton of use out of these incredible devices, helping ensure their reputation is as sparkling as their glass.
- Homeowners with large windows and a desire to keep things clean will also get a lot of value from their little robot friend.
While what’s the “best” window washing robot truly depends on your needs, you can’t go wrong getting the HOBOT-388. With an incredibly powerful, yet quiet motor, advanced AI, and all the most innovative features around, it’s hard to argue the HOBOT-388 is currently the very best window washer you can get.
The vast majority of these machines are straightforward to set up and use. After reading the manual for any crucial tips and tricks, connect the power and safety cables. Make sure the microfiber pad is adequately attached, pre-spray the window if necessary, hold the bot to your glass, and press power.
From there, many models will run automatically, or you can alter its settings via the remote control or Bluetooth enabled app. The robot will alert you when it’s finished its cycle with a clear indicator, letting you know it’s time to move it to the next location.
Window cleaning robots may seem very complicated, but properly caring for them doesn’t have to be. Simply follow these simple tips, and you’ll significantly increase the life of your robot and pads:
- Make sure to wipe down the various parts of your robot after each use.
- Most winbots won’t work particularly well in extreme temperatures. Always consult the manual if you’re concerned it may be too cold or humid.
- If you want to keep your microfiber pads fresher for longer, make sure you wash and dry them after every use.
- Run your cleaning robot once a week to prevent buildup that could cause more wear and tear.
Lots of people ask if you can use your winbot for other types of surfaces, such as mirrors, shower-door glass, and even floors. The short answer is, yes. Most winbots are well-equipped to handle each of these tasks, but it’s important to check your manual before doing anything. As for cleaning the floor, it’s definitely possible. That said, it’s worth noting they often don’t work nearly as well as robots designed for automatic wet floor cleaning.
Disadvantages of a Window Cleaning Robot
Weather Considerations
If you’re cleaning the exterior portion of your windows, a bot doesn’t work well in sweltering weather. It also can’t be used when weather conditions are at the opposite ends of the spectrum, such as when it’s snowing, raining, or temperatures plummet below 40º.
Thin Mirrors
If you’re going to use it to clean your mirrors, keep in mind that a bot could crack mirrors that aren’t very thick. If your windows are less than three millimeters, you should get a robot that uses magnets or clean them by hand.
Battery Powered Bots
While battery-powered window cleaners are less cumbersome, the average battery life is usually 30 minutes or less. Although that might be sufficient to clean approximately 10 windows on a single charge, you should get a bot with a cord attached if you have more glass surfaces than this.
Can Cause Streaks
The most common cause of streaky windows when using a robot is dirty microfiber cloths. Periodically inspect them and if they’re filthy, toss them in the washer.
When putting them back on the unit, be careful not to cover the movement tracks or sensors because this could result in missed spots or your bot falling off the window. However, check your manual first. Sometimes these cloths need to be cleaned by hand.
Can Be Noisy
Every window-washing bot has a motor. This means there’s always going to be some noise. However, window cleaning robots are relatively quiet when compared to most other household devices.
Try not to buy one that’s overly loud because it can be an annoying distraction if you need to concentrate on a task. Try to choose a machine that generates a decibel level of 65 or less, which is about as loud as a normal conversation.
Conclusions
While automatic window washers may not be for everyone, they certainly have a ton of value for some. For them, these robots have been a game-changer. It’s incredible to live in a world where automated machinery has solved so many of our daily problems. From business owners who can improve their appearance while saving manpower to the homeowner who values a tidy appearance, window cleaning robots have been an excellent purchase for many.

Good reviews on window cleaning robots. Thanks for sharing
Hi I am looking to clean a very narrow window – only 6 inches wide. Is there are robot that can help?
Hello, I have decent amount of full size and smaller windows in my house. What is considered a small window? I have two sectional windows, will the robot clean the whole window or one section and then I will have to move it to the other?
the post powerful tool only: HAND
Hello all,
I have a small question related to the cleaning liquid(s). Is it water? Is it a special window cleaner liquid?
Are window cleaning robots suitable for skylights?
Absolutely! Many models are designed to withstand gravity, making them ideal not only for cleaning the outside of a skylight, but the inside as well. A smaller window cleaning robot model may be better suited for your needs if you have a skylight that features a concave or dome shape.
Our new home has large A frame living room with lots of tall windows. The windows are flat however the tops of those windows are angled. Will any of these winbots work?
I have the same type of home and am looking to purchase a window cleaner. Which works best for timber house A-frame windows?
I have lots of windows! Perhaps 50% of the 30 are only 35cm x 130cm. Which robot is reccommended for smaller windows? As I have reading, many are only suitable for 50cm. The Hobot 298 is first on my list! Thank you, Rebecca
I would love to find a robotic window cleaner who can clean my sliding patio doors including the lightly curved top section.
Hello Lothar, that’s a great question. While most window cleaners only operate on flat windows, top quality models such as the HOBOT 298 are graded to work on slightly curved windows. That said, it still needs to be no more than 2-3mm RA.
Just want know how much hight can work and how much time please tell us with all details
Good day. Please let me know if the above product can clean outside windows on commercial buildings. 2. If so, please let me know the distant. I would like clean commercial building windows inside and outside. Regards
Hello Michael! All of the robots listed can clean both inside and outside windows on commercial buildings. That said, they typically only work as long as their power cables will allow, as many don’t work with standard extension cords. May we suggest the HOBOT-298. Not only does it have a long 15ft cable, but the massive 10×10 cleaning pad allows it to clean large windows rapidly. Thanks for the question!
Fantastic article concerning Winbots!
Extremely well done and complete.
Congratulations.
Very useful review and definitely helped my decision. One final thing can all these products be used across different surfaces, like marble walls and shower cubicles. I understand that they are limited to vertical movement but keen to know performance across different surfaces besides window. Which may just justify the price of some.
