Features to Consider


Just like every device offering several features, robotic window cleaners have highlights where you can base your decision when buying. Carefully considering and learning about the product’s highlights, abilities as well as drawbacks can help you get the best option for your needs.

It’s important to learn about these features and what they do, how they affect and contribute to the product’s potentials and efficiency. These are just a few of the many factors to consider when buying a robot window cleaner, but the ones below are the most crucial points you should keep in mind.


There are actually two ways how a robot window cleaner attaches itself on a surface: by suction or using magnets. In the early days of these machines, magnets were more often used as a method for attachment than vacuums. However, as time progressed and so did technology, suction-based models improved greatly and became more prevalent than magnetic window cleaners.

Today, almost all products in this category use vacuum for the robots to stick on the surface. It’s the reason why suction is one of the most crucial features to check when getting a robot window cleaner. The model you’re getting must have powerful suction for the robot to remain where it’s adhered.

You don’t want a product with weak suction or else it will be useless. Typically, the quality of the product’s machine determines the suction power. You will know if the robot window cleaner has a good vacuum by reading the product information. Looking around the feedback section can also help you know if the robot you’re getting has no issues about its suction power.



The size of the robot window cleaner is another crucial factor you must take into consideration when buying. There are compact and bigger models in the market. If you have small windows, it’s just right to get a robot with a small size. These models are typically the ones preferred for home-use.

For bigger robots, these products might work better for cleaning large surfaces such as glass windows and business establishments. Robot window cleaners also come in different shapes. Some look like boxes, while the dual-spinning models are typically more compact. The shapes may also determine the robot’s ability to clean nooks and hard to reach areas.

So when getting a product, make sure the size and shape of the robot you’re getting fit the type of glass window or door it will work on.


Most of the time, the weight of the robot plays a crucial factor on your purchase if you’re going to use it on delicate surfaces. For instance, you don’t want to put strain on a thin glass that’s easy to break. Thus, for such cases, you’d want to opt for robot window cleaners that are lightweight. Furthermore, the heavier the model is, the greater is the risk for it to fall off and break, especially if the back up safety feature like the rope or the tether is not durable enough.


Robot window cleaners have varying cleaning speed. In some cases, the larger the size of the unit, the faster it can complete a task. However, that’s not always the case. Some smaller models can be quicker than the larger robots. It depends on its mode of movements such as if it’s using wheels or rollers. Sometimes, the robot’s cleaning speed also depends on how powerful its machine.

Most models work using power cords. You will also find a few cordless robots. The cordless ones, however, typically have shorter battery life. Most of the time, the batteries of these robots are safety back-up if ever the it loses power. The back-up batteries will serve as a temporary power source of these machines, so they can remain adhered to the surface and then send off an alarm for a few minutes until it completely detaches.

Cable length

Because most models have power cords, you must take into consideration the length of the robot’s power cable. Especially if you have to use the robot window cleaner for large areas like offices and business establishments. Clearly, you will need lengthy power cords in such cases.

However, if you only need the robot for small spaces such as for home-use, perhaps you won’t need long power cords as sometimes if it’s too lengthy, there’s a chance it will get tangled in the middle of the robot’s chore.

Safety features


Safety features are one of the most important factors you should look for when getting a robot window cleaner. Most models come with multiple safety features to assure the robot won’t fall off and hit the ground. Because typically the robots work at a high area, it’s clear these machines must have back-up safety features if ever one of them fails.

Most robot window cleaners come with ropes or tethers that can hold them in case they lose suction and fall off the surface. Some models are equipped with technologies like UPS or uninterrupted power supply, which will act as the back-up power source if the main source runs out or runs low. Because these machines don’t come cheap, it’s important to look for these features to protect your investment.


As technology progressed, more and more robot window cleaners add AI features to improve the product’s efficiency. Many models today are equipped with smart technologies that can improve its cleaning quality. These technologies are behind the robot’s ability to detect edges, as well as the best path for cleaning.

Several robot window cleaners are app-integrated, too. For these models, you will have an option to use a smartphone app to control the machine or customize its cleaning modes and schedule. However, there are still many window bots today that are less high-tech, which are simpler to use. It depends on your preference. In most cases, too, the more advanced the technology the robot has, the pricier they can be.


No matter what size, shape or weight of the robot you’re getting, you should always know if it has a quality motor. An excellent motor also means powerful suction, fast cleaning, and a durable robot window cleaner. You can’t always read the details about the motor in the product information provided by the manufacturer. To know about it, the best way is to research and look around the customers’ feedback section.
