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 Omni is a versatile window cleaning robot designed for indoor glass surfaces, combining smart technology with practical safety and cleaning features. Its highlight is the TruEdge technology, which allows the robot to clean right up to the edges and corners, reaching within 1.1 mm for a thorough finish. The device uses three water spray nozzles that efficiently distribute cleaning solution, boosting stain removal with a powerful wet cleaning action. It offers both battery-powered (up to 110 minutes) and wired operation modes, making it flexible for different window sizes and locations—even places without nearby outlets. The 6-in-1 multifunction station adds convenience by serving as a charger, controller, and storage case.

Safety is a strong point here, with an advanced 12-level protection system that uses hardware and software to prevent falls and accidents, providing peace of mind during use. The robot’s intelligent route planning helps it clean efficiently, adapting to various window shapes and sizes. However, the device weighs over 7 kg and is not designed to be highly portable, which might make it less handy for frequent relocation. While it cleans well and reliably, the robot comes with only a single cleaning mode and speed, which might limit customization for users with specialized needs.

The WINBOT W2S Omni is suited for those looking for a safe, mostly hands-off, and effective solution to keep indoor large glass windows clean, especially if you appreciate edge-to-edge cleaning and smart operation. Its combination of wired and wireless modes and strong safety features make it a solid choice, though its weight and lack of multiple cleaning modes might not meet the preferences of all users.
