This guide will help you find out if you really need a robotic glass cleaner: so let’s find out what these devices can do for you and the considerations you’ll have to make before you buy one.

Windows cleaning can be problematic. It is one of those tasks that require a lot of effort and attention. Moreover, some windows are extremely difficult to clean because they are difficult to reach.

It is normal, therefore, to think of an automatic solution that can save you a lot of time and energy. This solution is the robotic window cleaner.

What are they?

What are they

These robots are compact and quiet, very easy to use and – above all – extremely practical.

All you need to do is just position them directly on the glass and they will take care of everything else.

Most robotic windows cleaners are lightweight, so they can “glue” to the glass without any problems. However, for a smooth operation, the glass must have a thickness of at least 5 millimeters. In addition these robots can also clean all glass surfaces (such as large tables).

Some of these robots can also clean surfaces made out of tile and marble.

What to know before choosing

Shape and size

Shape and size

The shape of these products varies greatly. The size, on the other hand depends on the glass surface you have to clean. A bigger robot is better when you have big glass surfaces to clean.

It is made up of three main parts, the motor that rotates the brushes responsibly for cleaning and the battery.


Battery life depends largely on the size of the device. In automatic mode most of these robots have an autonomy of about 20-25 minutes. In some cases it is possible to operate the robot while connected to the power supply. The bigger devices sport a bigger autonomy (about 45-50 minutes).

Battery life is one of the most important factors to evaluate when buying a robotic glass cleaner.

Remote control and smart functionalities

Nowadays, window cleaning robots include a wide variety of extra features.

Among these we can find a remote control or a dedicated app that allows you to control the device via your smartphone.


The prices start at about $120 (for the smaller models with no extra features). A mid-range robotic window cleaner costs around $200-220.
