In this video, I break down my Top 5 robot window cleaners you can buy right now, and I focus on what actually matters when you’re trusting a robot to hang on your glass—suction, spray system, navigation, and safety. I cover models from ECOVACS, Mamibot, and Hobot, and I explain why some are better for deep cleaning tough grime, while others are better if you want smarter edge detection on frameless windows or more flexible control with an app and remote. I start with the ECOVACS WINBOT W1 Pro, which I like for deep cleaning thanks to strong suction and its cross-water spray system. Then I go through the Mamibot W120-DP and W120-T AI, both using four nozzles and a 60 ml tank, with the AI model leaning harder into intelligent sensors and edge detection. Hobot 298 is my value pick with ultrasonic mist spray, AI route planning, and strong safety features like a safety rope and UPS backup—though it’s corded. My #1 overall is the ECOVACS WINBOT W2 Pro Omni because the dual power option (plugged in or battery) plus the 6-in-1 station makes it the most convenient, and the triple-nozzle spray + WindSlam path planning delivers consistently spotless results.
