Unboxing The Mamibot W120-T

Out of the box, you get your iGLASSBOT W120-T, a power supply, power cable, and safety rope, alongside a remote control with included batteries, user manual, and pairs of wet and dry microfiber cloths. It’s worth noting that cleaning fluid is not included, so be sure you have some or to buy some alongside your purchase.

After you’ve plugged the unit in, secured it with the safety rope, and attached a microfiber cloth spritzed with cleaning fluid to the bottom of the unit; you can start it up using an onboard button or the included remote.

Using The Mamibot W120-T

Included remote and an iGLASSBOT app are the most powerful ways to control the robot.

However, for the greatest array of functionality and control, we recommend installing the iGLASSBOT app. From there you can start and stop cleaning, manually control the robot, and even cycle through cleaning modes to find which works best for your windows.

The W120-T is quite responsive to commands, getting up and running quickly to rapidly clean the various surfaces in your home. Thanks to its intelligent pressure sensors, the unit is able to stay safely attached to your window throughout operation, and even has an emergency mode as backup in the event of power failure.

UPS and a safety rope are the major safety features of the W120-T

That’s right, in the event of a power outage or even if someone accidentally unplugging the machine, a built-in UPS battery will maintain suction for up to 20 minutes. During this time, it emits an audible beeping noise to alert you to the power disruption, allowing you to safely remove the unit or reconnect power.

The device utilizes Z, N, and even Z-to-N cleaning patterns, offering a greater variety of options and a more comprehensive clean than many competing machines. In addition, you can also manually operate the robot through either the remote or iGLASSBOT app to help tackle tricker spots on those odd-shaped windows.

As with any robotic window cleaning robot, or any robotic cleaning assistant, we advise manually cleaning the surfaces before initial use, especially if they are heavily soiled. Window cleaning robots are not designed to completely replace manual cleaning, only to make it much simpler and to ensure you have to do it less often.

Why People Love The Mamibot W120-T


There are plenty of reasons people love The Mamibot W120-T, with the standout compliments being just how well it cleans, and the surface area it can manage to clean in a single cycle. People rave about how well this machine manages to clean taller windows, and how well it can get into tougher-to-clean spaces too.

In general, people love how this machine complements their current cleaning routine, allowing them to clean their windows less frequently or only when there is a mighty mess to deal with.

Why People Dislike The Mamibot W120-T


There are some sporadic complaints about how the Mamibot W120-T may have difficulty cleaning heavily stained windows, which is common in the market as these machines were never designed to completely replace manual deep-cleaning, only complement and help.

Additionally, this model may struggle on windows with small borders that it can’t detect and avoid, as some have reported it detaching after dislodging because of that.

Is The Mamibot W120-T Right For Me

Finding the right window cleaning robot for your home can often be a daunting process. Trying to do your due diligence and conduct proper research can be quite time consuming, and the entire point in attempting to invest in a robotic cleaning assistant is to save time!

Thankfully, as always, the Cleanup Experts are here to help. You can compare this rating and more on our extensive window cleaning robots reviews page, filled with a variety of ratings and reviews for you to peruse.
