10 Best Robotic Window Cleaners

The Memows Window Cleaner Robot offers a solid option for those looking to automate window cleaning, especially for smooth surfaces like glass, tiles, and wooden doors. Its standout feature is the automatic ultrasonic water spray, which helps keep the surface moist and improves cleaning thoroughness. The robot uses a powerful 5600Pa suction system, ensuring it sticks firmly to windows and can tackle various dirt types without the need for manual labor. Safety is well addressed with a built-in lithium-ion battery that keeps it clinging to the window for up to 30 minutes during power outages, plus a safety rope and alarm to prevent falls on high-rise windows.

Navigation is intelligent, using a high-precision sensor to plan a Z-shaped cleaning path that covers the entire window area efficiently, and the remote control allows you to adjust cleaning directions easily. The double spiral wiping system combined with microfiber cloths helps remove stains effectively without scratching the glass. Noise levels are kept low, which is a plus for indoor use.

This robot suits homeowners who want a hands-free, safe, and efficient window cleaning solution for medium-sized areas. It excels in safety features and cleaning performance but might need occasional water refills due to its 35ml tank capacity, making it best suited for standard smooth window surfaces.

The ECOVACS WINBOT W2 PRO is a solid choice if you want a robotic window cleaner with smart features and strong safety. Its 3 nozzles wide-angle spray system boosts cleaning power by doubling water pressure and improving cleaning time, which helps remove dirt more effectively in one go. The WIN-SLAM 4.0 navigation system plans efficient paths using precise edge detection, so it works well on various window types including frameless or tilted ones. This robot climbs steadily thanks to an upgraded rubber belt system that resists water and slipping, making it reliable for both indoor and outdoor use.

Safety is a priority here, with a 10-level protection system combining hardware and software to prevent falls and accidental damage. It runs on lithium-ion batteries, which means no need for constant plugging in but requires charging and battery management. The brushless motor provides a quieter experience compared to older models. It’s a bit heavier and larger than some competitors, so keep that in mind if space or portability is a concern.

Controlled via an app, it offers convenience and multiple cleaning modes to suit your needs. If you have many large or hard-to-reach windows and want a device that adapts well to different surfaces with strong safety features, the WINBOT W2 PRO fits those needs nicely. However, if you prefer something very lightweight, you might want to compare with other models.

The ECOVACS WINBOT Mini is a compact robotic window cleaner designed especially for small, frameless, or oddly shaped windows that larger robots might struggle with. Its slim design allows it to clean windows with sides as small as 30cm and even those with handles nearby, which is a big plus if you have tricky window setups. It uses an ultrasonic water spray system that turns water into a fine mist to clean effectively without wasting water or leaving streaks, making it gentle on delicate glass and environmentally friendly by reducing detergent use.

The robot features an intelligent navigation system called WIN-SLAM 3.0, which plans the cleaning path efficiently, detects window frames, and avoids obstacles smoothly, even on complex windows. You can choose between three cleaning modes depending on how thorough you want the job. Safety is well-covered with a 9-stage protection system that includes hardware and software measures to prevent falls and damage, offering peace of mind during operation. It also has edge detection technology that cleans right up to the edges and corners by removing bumper rails, which can be a weak spot for many cleaners.

The product weighs 2kg, which requires reliable suction to stay securely attached. This robotic cleaner is ideal for users with small to medium-sized windows who want a safe, efficient, and eco-friendly solution that reaches areas many other robots can’t. For very large or heavily soiled windows, users might consider a more powerful or larger model.
