2. ECOVACS WINBOT W950 Robotic Window Cleaner

ECOVACS has done an excellent job with its WINBOT W950. What else can you expect when its price flies almost through the roof. It comes with a backup battery to maintain suction on the window in case of a power failure. In addition to this, there is a safety tether that adds extra security. The main drawback is it has less automatic features. In addition, the Smart Drive pathway behaves in a funny manner and you will notice your device dancing around while cleaning the edge of the window before realizing it has to turn around.

The company also offers a one-year warranty, just to make sure you stick with them no matter what happens. You will also be able to reach up to 16 ft high with this tether. So, cleaning tall bay windows is a lot easier as you don’t have to hop on to another ladder to reach out to the corner areas. We are also impressed with the 4-stage cleaning system. By the time you have done with the cleaning process, you will be left with a spotless streak-free shine. Robot weight is 5.3 pounds.

What Features You Should Look in Window Cleaner Robots

Size – Size matters a lot when it comes to window cleaning robots. It should be able to cover a wide surface area before the device’s battery runs out.

Weight – As they are going to move around on the windows, look for lighter ones. If the device needs more suction power it will eat up more power and leaving you less time to complete the job.

Power – This refers to the power of the motor. More power is required for large windows.

Speed – It should be fast enough to clean the maximum area with minimum battery power.

Suction – How long can your device stay on your window to get the job done. If a device has proper suction feature the job is half done. You don’t want your device to fall off and break it.

Framed or Frameless Windows – You will need minor manual works if you have framed windows. For framed windows, it is better to get a square bottom model to maximise battery life and the coverage space.

Battery – Cordless devices do not have long battery life spans. However, they can still do the job as most will give you about 30 minutes of use per charge.

Length of Power Cable – If you have a power source close to your windows you can save money on power cables.

Features – Some devices have additional functions that at an additional cost. For example, our number one pick device comes with remote control access via the official mobile app, thereby allowing you to clean certain areas manually as required.

Robotic Window Cleaners FAQ

Q: What is a robotic window cleaner?
A: They are like the big Roombas, which works from outside your window. They work on the same principle of a robot vacuum cleaner. It uses the same 3D mapping and smart technology to study which area to clean and how clean it should be.

Q: How to use robotic window cleaner?
A: You must first clear off a spot for first-use. As windows build up a layer of filth over a period of time, they should be cleared before letting the robotic window do the job for better results. Make sure that your tether (including the power cable if necessary) is properly fixed, with lots of slack to move about. Place the device on the window and hold flush with the pane. Start the machine and the robot will start moving on the window. Once the cleaning process is completed an in-built smart sensor try to spot the next area for cleaning. If the area is totally clean the machine will stop automatically.

Q: How to maintain robotic window cleaner?
A: There are some moving parts and you need to make sure they are properly maintained. They are not suitable for winter as most of them cannot work under 41’F and lower. If you are using the device during the day in the spring season, take them indoors at night. Humidity could damage your device. Every package comes with specific instructions on how to maintain the device. Read and follow them.

Q: Can I clean a mirror or shower glass using robotic window cleaner?
A: Yes, you can use it. Just make sure that your mirrors are of good quality and thick enough to sustain suction pressure of the machine. Otherwise, they will crack.
