Do Window Cleaning Robots Really Work?

Window cleaning is tedious and sometimes even dangerous if the house is multileveled and there are windows on the higher levels.

Professional window cleaning services exist, but they can be constrained by how busy they are and aren’t reliable when looking for a quick and immediate solution.

There are robots who can clean your windows for you just like a Roomba does for floors, and these robots work almost just like your robot vacuum.

But getting a robot just to clean your windows might not seem worth the asking price, so this article seeks to answer whether they are worth it.

After deciding for yourself whether they’re worth it, you’ll also get to see a few robots that come pretty highly recommended for their window cleaning abilities.

Window cleaning robots are a neat addition to a smart home with large windows because it makes the task of cleaning windows as easy as pressing a few buttons on your smartphone.

Find out if they are worth it and what features you need to look out for when searching for one.

What is a Window Cleaning Robot?

As the name suggests, Window cleaning robots autonomously clean your windows whenever you want.

They are basically a Roomba or a robot vacuum, but for windows and other glass surfaces.

Most window cleaning robots can learn the layout and shape of the window and clean them from end-to-end as a robot floor vacuum can.

Some can only be used on thinner glass, while others can be used on any glass.

This is because of how the robot stays attached to the window, which we will talk about later.

These bots can be either powered directly from mains as they are cleaning or by a battery pack.

The former setup would mean that there would be a long cable going from the robot to the mains, while the latter one may not stick to the window for long periods.

How Does a Window Cleaning Robot Work?

The most important part of a window cleaning robot is how it sticks to windows.

Some robots use a magnet on the other side of the glass, while some use suction motors where the robot touches the glass to hold on to the smooth surface.

Most robots can handle almost every window type imaginable, but some models won’t clean thicker windows because of the technology they use to attach to the wall.

Once the bot is attached to the wall, it will use its wheels and spinning pads to clean the window completely.

The vacuum and the dust pads go to work on the window as the bot moves around and cleans the surface.

Some bots do a dry run first to get the lighter dust out, then the process is repeated with a wet cycle that uses the water from the robot’s built-in water tank.

They can also know if a spot on the window is clean and are intelligent enough to move to the next area that requires cleaning.

The robots have apps that you can control them with, and generally, the stuff you can do with the window cleaning robot is similar to what you can do with a Roomba.

What are the Advantages of a Window Cleaning Robot?

The upsides to owning a window cleaning robot are quite many, but there are some that everyone must know.

The first advantage of getting a window cleaning robot is safety.

Cleaning the windows of multistory buildings is a risky task, and without the right equipment and skills, it can prove hazardous.

Homeowners can’t spend a lot of time learning the proper way to clean a window and the relevant safety precautions, so using a robot instead makes a lot of sense.

These robots can clean hard-to-reach parts of the window, which can be the case in a modern home where tall panes of glass are common.

Manually cleaning windows is a time consuming process that requires quite a lot of labor, especially if you run into a part of the window where the dirt is stubborn, and you’ll leave ugly streaks after the water dries off.

Being too aggressive with cleaning can shatter the glass, so let a robot do the cleaning for you instead of cleaning the window manually.

These bots are designed to clean almost everything in less than two cycles, so you’ll save a lot of time as well.

Windows aren’t the only glass surfaces you can use these bots on; dinner tables and other glass surfaces are also fair game for the bots.

Features of Window Cleaning Robots

There are a couple of basic features that any window cleaning robot can’t go without, and here is where the differences in the products in the market are mostly observed.

Cleaning Controls

Most robots come with multiple cleaning modes like dry only runs, wet only runs, and total cleaning, and the more modes the robot offers, the better it does when this feature is considered.

This also includes cleaning patterns and paths that the robot can take when it cleans so that the user can optimize the cleaning routine.

Almost, if not all, window cleaning robots, can be controlled with a smartphone app over Wi-Fi or Bluetooth, so you can relax and let the bot run and not even get up from your seat.

Magnetic or Suction

In order for the robot to stick to the window, they use either one of these two methods.

Some have a magnet that you’ll need to attach on the other side of the window, but you’ll need to have easy access to the other side of the glass, and the pane itself can’t be thick.

Others use suction motors on the robot’s underside where it touches the glass that holds the robot in place and includes a safety cable to catch a fall in case the suction doesn’t work.

Cleaning

Brushes, dry and wet cleaning cloths, or squeegee-type cleaners are commonly seen on these bots, and it only matters when you know what kind of cleaning your windows require.

How many of these cleaning surfaces your robot has depends on how it is priced, with higher-end bots having surfaces that cover every angle.

The bonus of being able to clean surfaces other than windows is also something to look out for.

Battery Life

For robots that do not run on mains power, battery life is an important aspect of how long they can run their cleaning cycles.

Look for a robot with a battery that can last cleaning at least half of the windows in a home.

Ensure the battery isn’t too heavy either because it can be unstable when going across a window.

While these are just aspects that anyone needs to consider when getting one for themselves, they are pretty important and can define the experience a person has with a window cleaning robot.

The Right Way to Use Window Cleaning Robots

After getting your own window cleaning robot, read the user manuals that came with the robot and follow the instructions to set up the bot.

Once you’re ready to clean, wipe down a small part of the window that needs to be cleaned.

Connect the power cable to the robot if yours requires mains power, and make sure it won’t snag on anything nearby and has enough slack to move around.

Place the robot on the windowpane and press the power button, and attach the magnet on the other side if your robot uses one.

Attach the safety rope for robots that don’t use a magnet and secure the robot from falling.

After pressing the power button, the robot will beep and connect to your phone app.

Use the app to control the cleaning routine of the robot and check the battery levels to see if it is full.

The robot will start moving on its own and clean everything; once its done, it will stop and let you know by beeping and sending notifications to your phone.

Disadvantages of Window Cleaning Robots

Some robots that use safety tethers to keep them from falling can be pretty restrictive in the sizes of the windows that you want to clean.

The safety tether might not be long enough for a large window, and you may find yourself adjusting the tether all the time.

The robots also struggle with curved windows because they almost entirely depend on flush contact with the window when cleaning.

When windows curve, this contact will break, and the robot will fall.

The robots that use a magnet to stay on the window become unusable if the other side of the window is inaccessible, like several stories up in the case of a window.

Window cleaning robots still do a lot of work even if their domain of application is pretty niche.

Quite a few popular robot vacuum brands have also launched their own line of window cleaning robots.

HOBOT is the most recommended window cleaning robot brand, and they offer a lot of models at around the same price point so that you can pick and choose.

Alfabot is also a highly rated brand that focuses on the affordability side of the market and offers a lot in terms of features.

Gladwell is another brand that does the budget segment well, and you can’t go wrong with choosing either of the budget options mentioned here.

Are Window Cleaning Robots Worthwhile?

While at first, it might seem that window cleaning robots fulfill a niche in the home cleaning market, once you start using one, you’ll start feeling the difference.

It makes a massive difference in homes with many windows, which is actually what modern architecture is focusing on.

As houses with large windows become more popular, these robots will gain popularity because it trivializes the most difficult part of having large windows, which is to get them cleaned.

Sure, you could hire a professional team, but that could go to a few hundred dollars extra than what you might need for one of these robots.

The robot won’t be as thorough as people, but running the robot often would solve that issue.

Overall, window cleaning robots are a great addition to a smart home with smart cleaning solutions.
