10 Best Robotic Window Cleaners

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.

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 SqueeGBot Window Cleaning Robot stands out with its Intelligent AI 5.0 Navigation, making it a prime candidate for cleaning large, panoramic windows, tiles, and mirrors. Its navigation system is designed to ensure efficient cleaning, minimizing missed spots. The dual spray system allows for thorough cleaning, providing a polished finish to surfaces. Additionally, with a powerful suction of up to 5300 Pa, it securely grips glass surfaces, making it effective in removing stubborn dirt and rain stains. This model is especially appealing for those looking for a hassle-free cleaning experience due to its remote control feature, allowing users to multitask while the robot does its job.

However, the SqueeGBot does have some limitations. It is corded, which might restrict its range of operation compared to cordless models. The runtime is also relatively short at just 30 minutes, which may require frequent breaks for larger cleaning tasks. Despite being portable, the robot weighs 5.01 kg, which might not be as lightweight as some users would prefer. On the upside, its ergonomic design includes a portable station that helps with easy storage and avoids cord clutter. The safety features such as edge detection ensure it avoids falling from edges, an essential aspect for vertical cleaning tasks.

While the product is equipped to tackle indoor and outdoor windows, its corded nature might limit its usability in certain scenarios. It's a promising choice for users who prioritize thorough cleaning and advanced navigation in a robotic window cleaner, especially for homes with large glass surfaces.
