Robots are the future

Just a few decades ago, most of the things we did had to be done by a human being, or with human supervision like when a machine does the work while it is being operated by a person. However, with advances in automation technology, this is no longer a requirement.

You can get a robot that does all the hard work without requiring you to lift a finger. With some of these robots, you don’t even need to be there. There are robots for anything from mowing lawns, cleaning the floors in your home, tilling gardens, and even cleaning windows.

The Need for a Window Cleaning Robot

Cleaning windows is definitely not the most exciting chore in the world. If you are like most people, it is probably top on the list of the chores that you dread. This is because it is boring and will usually involve sitting, standing or squatting in uncomfortable positions trying to reach all the parts of the windows.

This probably explains why a good number of buildings have their hard to reach windows covered in dust because of the years without getting any attention from anyone simply because they are located on parts of the structure that are hard to reach.

In addition to the discomfort, cleaning windows can easily turn out to be dangerous if you try doing it without the right tools equipment. You can easily fall and break a limb or injure yourself as you try to reach a window that is on the higher levels of your house.

With a window cleaning robot, this no longer has to be a concern. To clean your windows, you will only need to ensure that the window cleaner is fully charged, turn it on, place it on the window, and it will do the rest.

How Window Cleaning Robots Work

Robotic vacuum cleaners are very easy to operate. Their basic components are cleaning pads, a cleaning solution, a power adapter for charging the device and safety tethers to ensure that the device does not fall off when in use.

To clean your windows, the robotic vacuum cleaner moves from one edge of the window to the other systematically cleaning the entire area of the window. The end result is a clean window with no stripes – something that is very hard to achieve should you decide to do the cleaning yourself.

When the cleaning is done, most robotic window cleaners will play an audible tone to let you know that the cleaning is complete and you can move it to the next window that needs to be cleaned. Apart from applying the cleaning solution, placing the machine on the window and removing it after it is done, you really don’t need to do anything else.

How Do Window Cleaners Attach to Windows?

If you have never used a window cleaner before, this is probably the biggest question on your mind right now. Most windows are designed to be vertical. With this in mind, a window cleaner will have one big challenge in its operation. How is it going to defy gravity enough to ensure that it moves around the window surface without falling off?

With respect to this problem, there are two types of window cleaners:

Suction Connectivity

In these window cleaners, the motor generates suction that is used to hold the machine in place on the window surface as it does the cleaning. This type of connectivity is convenient in that you don’t need access to both sides of the window to attach the cleaner. However, the connection is more prone to fail, which explains why most window cleaners that use this connection come with a tether or safety cord.

Best Robotic Window Cleaners

Magnetic Connectivity

This connection uses magnetic attraction to keep the cleaner attached to the window surface. The operating principle is simple: Two magnets will attract if they are placed close enough. So the underside of the cleaner is fitted with a magnet, and the cleaner comes with a small magnet that you will need to place on the other side of the window glass.

The magnetic attraction created by the two magnets holds the cleaner in place as it cleans. Some models use two magnets on opposite sides of the window while others use a piece of magnetic metal on one side and a single magnet on the other side. Either way, the principle does not change.

Magnets vs. Suction

Now and again you may come across a machine that’s design incorporates both magnetic and suction based technology, but it is far more likely that the window cleaning robots you will come across use one or the other.

When winbots first took off, magnets were by far the more popular design option, but as technology develops and advancements in vacuum and motor standards push on, suction based robotic cleaners are quickly taking over the market.

Over the past few years, the power and quality of suction based cleaning technology has grown exponentially and as a result the popularity and versatility of these machines has become very impressive. From kitchen windows to skylights, suction based robotic cleaners can provide a generally faster and more effective clean on almost any surface.

This is one of the biggest benefits of suction over magnets, as machines using magnetic tech can only be used on a surface that allows for a magnet to be attached to the other side of the glass. As a result, they are less adaptable and not as useful all round- probably the main reason for their dwindling popularity.

There are, of course, some upsides to magnetic machines, the first of which is noise. Although the more high-end suction cleaners have been successfully designed to minimize noise levels, generally speaking they are pretty loud. Magnet based models are far quieter and more discreet when working.

Without a doubt the biggest advantage of magnetic cleaners is not having to worry about the machine falling off. Despite improvements in back-up battery technology significantly reducing the risk of suction cleaners falling, the possibility remains and you may need to attach a safety rope to avoid any accidents. Unlike these machines, magnets do not rely on power, so getting disconnected or running out of battery and losing grip is not a concern- a fact people may view as a major benefit.

With either design, it is important to check the machine’s specific instructions if you plan to use it on an uneven surface as this can bring complications regardless of each system’s advantages or disadvantages.

Should You Get One?

Just like any other robot, window cleaning robots are not exactly cheap. The big question is, should you invest in one? Will the cleaner give you value for the few hundred dollars spent?

For starters, if your windows extend to very high parts of the building, then a window cleaning robot will definitely be worth every dollar spent. No matter how expensive the cleaner is, the risk of losing a life or breaking a limb when trying to clean your home is just too high.

The other scenario that makes a window cleaner absolutely necessary is if you have large windows with a wide span of glass. This means that you would have to spend a lot of time cleaning, coupled with the fact that you might not find a hard surface to lean a ladder on so that you can clean all parts of the window.

It could also be that you simply dread cleaning windows. As mentioned earlier, it is not the most exciting household chore. On top of that, most people will still not do a very good job when they try to do the cleaning themselves. If you can’t leave dust to accumulate on your windows but don’t want to do the hard work, then you will find the investment in a window cleaning robot worthwhile.

A Buyers Guide to Choosing a Window Cleaning Robot

Now that we have shown you some of the most popular models, let’s take a closer look at some of the things that you should look out for when narrowing down to that one device for your home.

Best window cleaning robot

Type of Connectivity

There are two most common methods that the window cleaner will use to attach itself to your window. The first one is magnetic, which is not very common, and the second one is suction. As discussed earlier, magnetic connectivity will need you to have access to the opposite side of the window so if you have an area that is inaccessible from the other side, the window cleaner will not be able to help you.

Suction-type window cleaners are easier to use and more convenient, but they are also prone to failure so you need to make sure that you have sufficient backup methods.

Best window cleaning robot

Battery Life

Most window cleaners will only work when connected to electricity, but they will also come with a battery that will serve as a power backup. This is because most suction type window cleaners use the motor to develop the suction that is used to defy gravity hence if the power is suddenly disconnected, the machine will have no way of staying on the window.

This is why many manufacturers will include a battery that will keep the window cleaner safe on the window surface in the event of a power disruption. Find out how long this battery will keep the cleaner on the window before running out. As a general rule, the longer it lasts, the better.

HOBOT-298 Review


A window cleaning robot should be able to clean your windows automatically with no input from you. However, it is common to find that a spot on your window needs more passes before the stain is fully removed. This is where you would need a window cleaner that comes with an option to override the automatic cleaning so that you can make these passes.

Most models will come with a remote control that you can easily use for this. Some will even have a smartphone app that will enable you to do even more with your window cleaner while making the entire cleaning process more convenient.

Availability of Spare Parts

Just like it is with a robot vacuum cleaner, you will also need to replace some parts on your automatic window cleaner. This is because as it cleans, the cleaning surfaces will gradually be exposed to wear and tear hence the need for replacement.

A good window cleaner should have replacement parts readily available in local stores. Before you make a decision to buy, ask where you can buy extra cleaning pads and cleaning solution for the model you like. If you find that you will have problems getting replacement parts, it will be a good idea to purchase a model with more available parts. They should also be affordable.

Window Design

Automatic window cleaners are not the same. Some will work better in different settings than others. For this reason, it is important to consider the design on your windows when choosing a window cleaner.

For example, some window cleaners will keep falling off the surface when used in frameless windows while others will work just fine. On the other hand, some cleaners will not be able to clean the corners properly if you have rectangular or square windows because their brushes are circular.

It is therefore important to make sure that you choose the window cleaner that will work best in your particular situation.

Best Robotic Window Cleaners

Power Cord Length

The power cord that comes with your window cleaner will determine how far the cleaner will be able to reach without the need for extension cables. Although most window cleaners come with long power cords, they may not be sufficient in cases where the power outlet is far from the window.

You might also have a problem with the power cord if you have very tall windows so make sure that you find out exactly how long the power cord is so that you can ascertain that it will be sufficient in your home or office.


Most window cleaners are generally quiet, but this does not mean that they all are. A window cleaner with high noise levels can easily become a distraction especially if you are using it in the workplace or around children.

If noise is a problem in your environment, go for the models with low noise levels. Noise levels around or below 60 dB should be fine even for use in the office.

Cleaning Process

Each window cleaner uses a different process to get your windows clean. Depending on how dirty your windows are, you might see a difference in the results obtained. Some window cleaners use dry cleaning pads to wipe off any dust or dirt on the window surface while others are more thorough using brushes, cleaning liquids and squeegees to get the job done.

If your windows typically have a lot of different types of stains, you will be safe with a window cleaner that uses two or three cleaning steps. Simple dry cleaning may not be sufficient in this case. However, if your building is a number of stories high, you are most likely going to be dealing with dust and other easy to clean stains hence you can go for a cheaper single-step window cleaner.

Top Robotic Window Cleaners

Speed of Cleaning

Although they automatic window cleaners, these devices are still not able to move from one window pane to the other or from one side of the window to the other. The cleaning may be automatic, but you will still need to be present to move the device from one pane to the other.

A quick window cleaner will ensure that you are done with the chore faster so that you can go back to other things. However, speed should not be at the expense of cleaning performance.

Safety Options

We have already mentioned a backup power source for safety, but that is not all. Automatic window cleaners are expensive devices. You don’t want to damage them when they drop during use. For this reason, it is a good idea to pick a device with a tether that will ensure that no damages occur even if the device is dislodged from the window surface.

Size, Shape & Weight

Window cleaning robots come in various shapes and sizes, and when it comes to buying the right windor robot cleaner, size does matter. It’s really a case of common sense, meaning you base the size of the machine on the dimensions of the windows you need it to clean.

A huge, flashy robot may look good, but it will be fairly useless if you have small windows it can’t even attach to. If, however, you have large glass surfaces then a compact, handy robot window cleaner won’t seem so handy when it takes way longer to cover the full area.

The same applies when choosing the shape of your potential machine. Don’t pick a model that will struggle to clean corners (dual spinning models, for example) if your windows are all cornered. These types of machine are, however, perfect for circular windows.

Weight may not strike you as a hugely important factor when buying a robotic window cleaner and in most cases it’s not, because design evolution has perfect the ratio of power to weight. This consideration is important only when it comes to the thickness of your glass.

Many older houses have thin glass windows which may not be able to support a heavy machine, so make sure you check your windows and the minimum thickness specifications on your potential machines- otherwise you could find yourself regretting it later!

Quality Of The Motor

The efficiency of your robotic window cleaner is tied closely to the quality of it’s motor. The better the motor, the stronger the suction and the less risk of your winbot falling. The motor will also directly influence both the movement and sound of your machine, with higher quality translating to smoother, faster motion and significantly reduced noise levels.

The high-end models with the best motors work quickly and quietly enough to keep them running in the background while you relax, but standard motors may be a little more disruptive.

Window Surface

For optimal cleaning results, you need to consider the texture of the glass and make sure you buy a compatible robot model capable of working on that particular surface. Whether your windows are smooth, rough, glossy or patterned, using an unsuitable winbot can end up damaging the glass so be sure to check the specifications.

Window Thickness

Unless you want to risk wasting time and money buying a machine you can’t actually use, we recommend measuring the thickness of your window before deciding on a device. Each robot will have individual specifications which you can check are compatible with your glass.

Window Shape

The majority of robotic cleaners are designed for large square or rectangular windows, so if yours are all this shape you will have a fairly extensive selection to choose from. If, however, you have small, circular or oddly shaped windows you will need to look into machines matching your needs.

You should also take into account your window frames, as not all machines are suitable for framed windows and others are designed specifically for them. It’s also possible to find a winbot compatible with either specification, the main thing is that you check before you commit to buying.


What is a Robotic Window Cleaner?

Essentially, winbots are Roombas for windows. They use very similar technology and follow the same type of process to intelligently clean your home or windows. They are bigger than the average robot vacuum cleaner and attach directly onto your window, then use smart tech and 3D mapping to figure out how and where to clean.

Robotic window cleaners are one of the latest advancements in automated home technology and have all but eliminated yet another tedious chore. Other than the brief time it takes to set up and move from surface to surface, winbots are entirely self automated.

How Useful Are These Winbots?

For businesses or homeowners whose properties have lots of large hard to reach windows, a robot window cleaner could be a very worthwhile investment. In this situation, a robotic window cleaner is an extremely useful tool as it would save you a huge amount of time, effort and eventually money by eliminating the need to hire professional window cleaning services for jobs you can’t do alone. These machines can have your windows in perfect condition much quicker and easier than any person could, the benefits of which far outway the initial cost.

How do I operate my Robot Window Cleaner?

The idea of robotic window cleaning machines may seem super complicated and futuristic, but thankfully the set up and operation is basic and very manageable. In most cases it’s a matter of connecting to power and safety cables, properly attaching the microfiber pads, holding the winbot to the glass and off you go.

Some surfaces might need sprayed before you start, but your manual will have all the special tips and info for your particular bot so check it out before you start. Depending on the model, you can control the settings via remote control or bluetooth app, and many will operate automatically without you needing to do a thing. When the cleaning cycle ends, your robot will send you an alert so you can power it down or move it along to the next task.

Can these Robots Clean Frameless Glass?

Unfortunately, no they can’t. One of the features the robotic window cleaner uses to determine the dimension of the surface and map out its path is a frame detecting sensor. If the machine can’t pick up on a frame, it won’t know where the surface ends and could easily fall off the edge.

What’s The Maintenance Like?

As high-tech as these machines may be, they only require simple care and maintenance to keep them in working order. By following these tips, you can easily treat your robot the way it should be treated to maximize its functionality and lifespan:

– Wipe the winbot after every use.
– Be sure to clean every part of the robot every time you use it. A simple wipe down is enough for the most part.
– Avoid using your window robot cleaner in extreme temperatures. They don’t do very well if it’s too hot or too cold, so check the manual for details of what temperatures are deemed ‘safe’ and won’t lead to potential problems.
– Washing and drying your microfiber pads each time you use them will prolong their freshness so you won’t need to replace them so often.
– Even if you are not cleaning any windows, run the winbot weekly to keep it clear and avoid any build up inside which can reduce the efficiency.

Will they clean vertical sheetrock walls?

Whatever the surface- provided it’s completely smooth- these robots can handle it. Whether it’s laminate, mirror, countertops, table or even overhead surfaces, window robot cleaners are designed to adapt and perform.

Can I Clean Mirror or Shower Glass With a Robotic Window Cleaner?

Generally speaking, yes. One thing to consider, however, is the quality and thickness of the glass. Some cheap mirrors may look thick but there is a layer of ‘silvering’ behind the glass to make it reflective, so the glass itself could actually be too thin to support the weight and suction of the winbot and could end up cracking. Try to get an idea of the true thickness before attempting to attach your device.

Shower glass is a different story. Because of certain industry standards which are in place to ensure a minimum glass quality, you should be good to go without any worries.


Automated cleaning devices have taken housework to a whole new level, and winbots are no exception. Forget spending valuable time sweating and straining to reach tricky windows, balanced on a ladder battling streaks and smudges. The level of convenience these machines bring is second to none, especially for those with hard to reach windows who have been paying for professionals to come in and do risky jobs with all kinds of special safety equipment and high costs.

Robotics are changing the world we live in and the way we handle day to day tasks. The mundane is no longer mundane, and perfect cleanliness is a far more achievable goal than ever before. Whether your business needs sparkling windows to keep that perfect first impression, or you just love your home to look the best it possibly can, a robotic window cleaner is a great investment and will not disappoint.
