Should You Buy a Robot Window Cleaner?

If you "don't do windows" then a window cleaning robot maybe for you. However, if they don't do a good job you may want to wait before you make a purchase.

Ever heard someone say "I don't do windows"? With the advancement of robotic cleaners for the home not only will people not have to "do windows" but floors, lawns, litter boxes, pools, etc. Robotic cleaners can be a big time saver by taking on some of our most hated chores from the to-do list. 

For me window cleaning ranks pretty high on my most hated list. So needless to say I'm pretty excited about the possibility of a robot doing it for me. Today we are going to look closely at automatic window cleaners; what are they, how they work, features to look for and more.

What is an Robot Window Cleaner?

An automatic window cleaner in a way is like a robotic vacuum. It uses advance sensors to guide itself around the cleaning surface in the most efficient path. Of course their are some obvious differences, namely it cleans windows instead of floors.

Most automated window cleaners use suction, magnets or a combination of both to stick to the window or other glass surface. This is an important point as there have been complaints buy some users that the suction of certain models was strong enough to break their window. More on that later.

How does an Automatic Window Cleaner Work?

In general, all robotic window cleaners work by combining automated movement with window cleaning technology. These cleaners stick to windows using motor-powered suction technology and/or magnets. Once these cleaners are stuck to a window, they start cleaning automatically from one edge to the other. They are beneficial because they enable you to clean high, out-of-reach spaces.

Although most robotic window cleaners offer similar general features, they also provide varied functions, height restrictions and cleaning techniques. They typically work by sticking on windows and cleaning with the help of brushes or pads, in some cases a series of both in addition to a squeegee.

How do they Clean Windows?

Cleaning methods vary between the different models. Some robots use a cleaning pad and spray along with squeegees while others have rotating scrubbing pads combined with a vacuum.

Whatever the method, a quality robotic window cleaner uses it should clean a window thoroughly from edge to edge. Additionally, it should alert you when it is done cleaning.

Depending on the quality, some automatic window cleaners actually do a pretty good job, while others may leave streaks that have to be taken care of with a quick once over. The main advantage of these innovative cleaning tools is they can get to high areas that pose a risk to you the window cleaner. This can be a dangerous task even for the pros who are equipped with skills and sophisticated cleaning tools.

Advancements in Automated Window Cleaning Technology

A recent robotic window cleaner invented by teenager Sohail Abdulla promises to improve robotic window cleaning significantly. He managed to make the size smaller while making the cleaning more efficient and convenient. Sohail’s understanding of complex design principles has resulted in an elegant and functional system that makes window cleaning a breeze.

Manufacturers of these robotic cleaners are dedicating considerable resources and human effort to ensuring that more research is done to improve these cleaners.

Different models have different operations processes.

Most robotic window cleaners will need the user to change out the pads or brushes periodically. These cleaners have sensors attached to them. The sensors sense frames and edges to allow the robotic window cleaner to cover the entire glass surface. Some robot cleaning windows are multi-functional; this means they also clean other glass surfaces apart from windows.

Typical three-phase cleaning process

The robotic window cleaner sticks to the window surface and then start cleaning at the touch of a start button. The cleaning pads and the cleaning fluid will wipe off the dirt and then most have a squeegee that dries the glass surface to ensure the window is spotless.

This three-phase process mimics the cleaning process that must human cleaners follow. This cleaning process is very reliable because it does not leave any streaks unless the pads are dirty. Most robotic window cleaners play a loud enough tune to notify you when cleaning is done; this is an outstanding innovation that makes window cleaning a simple and even enjoyable task.

So now that we learned what a robot window cleaner is and how it works, let's answer the most important question...

Is a Window Cleaning Robot Worth It?

In short, the automatic window cleaners available today are not worth it for most home owners (yet). From researching reviews, we have found that many customers have complained of streaky windows, water spots and even the robots falling off the window. 

While these automatic window cleaners have come a long way, they still have a lot of room for improvement. So if you are looking for neat and streak-free windows, you may want to consider hiring a professional window cleaner or cleaning them yourself more frequently.

With all that said there are still some home owners that may benefit from owning one.

Who Should buy a Robot Window Cleaner?

Really a robot glass cleaner is for anyone who hates cleaning widows! That also includes people who have:

  • Large households with glass window surfaces that are hard to reach
  • Commercial spaces that are made up of large glass windows located on high altitudes
  • Robotic window cleaners are a basic necessity for commercial cleaners who want to expend their clientele base
  • The budget to afford the hefty price tag of the higher quality models

If you are considering purchasing a robot window cleaner, keep in mind that how well they do is dependent on how dirty the window surfaces are. Streaking occurs more often if windows are extremely dirty, this can normally be cleared up by changing pads. Even then, you may still need to touch up your windows when the robot is done.

Now that you know what to expect from a robotic window cleaner, you'll need some tips on how to select the best model that works for you.

What to look for in a Window Cleaning Robot

Battery Life

It is a fact that most robot window cleaners have a short batter life that only allows cleaning less than 10 standard sized windows on a single charge. This means battery life can last from 15 to 30 minutes depending on the model or brand. Battery life is an indispensable consideration.

Power Cord Length

In case you are considering a robotic window cleaner that needs an external power supply, you need to consider the length of the power cord. Ensure the power chord has enough length to meet all your window cleaning needs. Most models in the current market typically come with a 20ft cable along with an extension cord. The longer, the better depending on the height of your windows

Magnetic or Suction

As mentioned earlier there are two types of connectivity either motor-powered suction or magnetic connectivity. In most cases magnetic connectivity requires another magnetic piece strategically placed on the opposite side of the surface being cleaned. This makes motor powered suction more convenient as the robot is only placed on one side.

A disadvantage of a motor-powered suction robotic window cleaner is that the connection can sometimes fail. This means every user needs a safety cord to ensure the robot does not damage your window sill. The other downside is some models have been known to break windows from the high suction power. Again before you choose make sure that the cleaner is rated for the thickness of your windows.

Automated Cleaning or Remote Control/App

Most robot window cleaners either come with remote controls or automated cleaning options; some feature both. And there are a growing number of them that are Wi-Fi capable, meaning you can control them via your smart phone through the manufacture's app.

Automatic mode is very beneficial; it allows user the convenience of sitting back comfortably while our glass windows are spotlessly cleaned. However, many users have reported they have to keep an eye on their little helper because it may get stuck or clean the same area over and over.

Using the remote control or the app on the other hand enables users to steer the window cleaning robot around the surface of the window.  For versatility, models that include both control options are preferable. This is because the allow users to choose the cleaning method that is perfect for their windows.

The cleaning process

Most window cleaning robots either use cleaning pads or cleaning brushes. Most feature a drying tool such as a squeegee that helps to ensure the glass surface is spotless and streak free. The number of pads or brushes will depend on the particular model. . Most robotic window cleaners typically feature a two-step cleaning process which begins with wiping off the dirt and then finally polishing the window.

Support and Maintenance

Just like any piece of machinery, your window cleaner can break down so it's important to consider what support you are offered by the manufacturer. Is there an online support and does it come with a warranty? Spare parts are also an important consideration; how much are the spare parts and are they readily available anytime they are needed?

Window Type

Window Shape

Robotic Window Cleaners are not typically designed for small windows or circular shaped windows. They are largely meant to clean square or rectangle shaped, large windows.

Window Surface

Some models can clean on rough and uneven surfaces while others only clean smooth and glossy surfaces. Modern windows come in different glass-surface designs ranging from patterned and filmed surfaces to frosted and textured surfaces. It is advisable to select a robotic window cleaner that is able to effectively clean the particular glass surface in question.

Window Thickness

Most of these robots have a specific range of thickness they can clean so ensure you look out for this if you are in considering buying one. It is advisable to get an accurate measure of our window’s thickness and then match it to the particular robotic cleaner you intend to buy.

Where to buy an Automatic Window Cleaner?

There are different models of robotic window cleaners to choose from in the current market. To ensure you spend your hard earned money wisely, it is recommended to consider the particular features that suit your specific needs. In addition to these considerations here are some effective tips that will come in handy in ensuring you purchase a robot model that work for you;

  • Take your time to observe the robotic window cleaner you want to purchase; a product demo is very effective. In some of our individual product reviews we include product videos so you can see it in action.
  • Reading customer reviews is another great way to find information on an individual window cleaner. Amazon has a good selection of automatic window cleaners with plenty of reviews from verified customers.
  • Many department stores do not have a large selection to choose from. Therefore we recommend looking online first before spending the day going from store to store only to find they don't have the one you want. Reading reviews, watching videos and getting the user manual before you buy is all possible online and will give you more information than most of the salesmen at the store could.

The Bottom Line on Robotic Window Cleaners

 As you may have noticed, robot window cleaners are becoming more and more popular. And while their performance over the years is improving, the technology is not perfect.

If you're on the fence about whether or not to invest in one of these automatic window cleaners, we've got some things to consider before making that investment decision. Here are three questions you should ask yourself: 1) What is my budget? 2) How many large windows do I have? 3) How often do I clean windows at home? If you only need it once every few months, then an automatic window cleaner with a higher price tag may not be worth it. However, if you plan on using it regularly, then investing in a high quality window cleaning robot could definitely be worth it.
