The ECOVACS WINBOT Mini 2 is a compact and lightweight window cleaning robot designed especially for narrow and frameless windows. It’s great if you have slim or hard-to-reach windows because its small size (just 215 mm wide and 55 mm thin) allows it to clean tight corners efficiently. Thanks to its improved four-corner brushes, it cleans almost right up to the edges—covering about 90% of window frames—which means fewer missed spots along the edges.

This robot uses ultrasonic misting technology combined with a professional cleaning pad and good pressure to tackle stubborn stains and leave your glass streak-free. It offers six different cleaning modes that you can control easily through an app, so you can choose the best setting depending on how dirty your windows are. The smart WIN-SLAM 4.0 navigation system helps it plan cleaning routes well and avoid missing areas. On safety, the WINBOT Mini 2 is equipped with a thorough 10-level security system, from hardware to software, and even comes with commercial insurance for extra peace of mind. It operates quietly at about 65 decibels, which is roughly the noise of a normal conversation—not too loud while running.

This device runs wirelessly on a rechargeable lithium-ion battery, making it convenient to use without worrying about cords. However, it’s designed for indoor use only and weighs close to 3 kilograms, so while portable, it's not the lightest window robot you can find. This makes the WINBOT Mini 2 a reliable, safe, and smart robot for cleaning indoor glass surfaces, especially slim or frameless windows. It may not be the best fit if you need a quieter or ultra-light model, or if you want to clean outdoor or very large windows regularly.

The ECOVACS WINBOT W3 OMNI is a thoughtfully designed window cleaning robot that stands out with its powerful cleaning and smart features. Its suction power is strong at 800N, ensuring it sticks firmly to glass surfaces for safe operation. The robot supports wireless operation with a rechargeable battery, but can also run plugged in, giving you flexibility depending on your cleaning needs. It offers multiple cleaning modes including quick, intensive, and zone cleaning, so you can customize the process based on how dirty your windows are or to focus on specific areas.

Edge detection is handled well by the TruEdge technology, which actively lowers the scrubber to thoroughly clean window corners and edges, a feature not all window robots manage effectively. The device also features intelligent navigation (WIN-SLAM 5.0) that avoids obstacles accurately, making it reliable for complex window layouts. Its multifunctional station automatically cleans and dries the mop pads using high-pressure jets, saving you time and effort on maintenance. Safety is a priority too, with 8 hardware fall protection sensors to prevent accidents.

The size and weight (about 3.8 kg) might make it less portable and best suited for regular home windows rather than frequent transport. It is designed only for indoor glass surfaces. For users looking for a strong, smart window cleaning assistant with less manual work on mop cleaning and good edge performance, the WINBOT W3 OMNI presents a solid choice, especially for those wanting app control and automated maintenance.

The ECOVACS WINBOT W2S is a window cleaning robot designed mainly for indoor use, offering advanced features that make cleaning easier and more thorough. It stands out with its TruEdge technology, which allows the scrubbers to clean very close to the window edges and corners, reaching within 1.1 mm for a nearly spotless finish. The robot uses three water spray nozzles that distribute water evenly, enhancing cleaning power by dissolving dirt more effectively than older models. Its cleaning brushes rotate at a good speed to scrub away grime, supporting a deep clean.

Thanks to a smart route-planning system called WIN-SLAM 4.0, the WINBOT W2S maps your windows and optimizes its movements, boosting cleaning efficiency by about 30%. This system also helps it adapt to different window types, including frameless or tilt windows. Edge detection works quickly and accurately, even on reflective or dark surfaces, preventing falls and missed spots. Safety is a strong point, with a 10-level protection system combining hardware and software safeguards to avoid accidents like falling from windows. The robot uses a sturdy, water-resistant rubber belt for climbing, ensuring smooth and stable movements without slipping. It runs on rechargeable lithium-ion batteries and is controlled via an app, giving you wireless convenience without being tethered.

The robot is designed mainly for indoor windows and weighs about 3.1 kg, so it’s not very portable for outdoor or heavy-duty use. It fits well for users wanting smart, careful cleaning of indoor windows with reliable edge detection and safety features. It is ideal if you value automated, hands-free cleaning with good spray and scrubbing power, although it may not suit those needing quieter operation or outdoor window cleaning.
