ECOVACS WINBOT W2 Pro
Premium window robot with 5,500Pa suction, WIN-SLAM 4.0, and 7 cleaning modes.
Mamibot W120
Our Verdict: The cheapest name-brand window robot — don't expect miracles, but it does clean windows at a price that's hard to argue with.
The original Mamibot W120 remains the brand’s most affordable option, delivering 2,800Pa of suction in a simple, functional package. It handles basic window cleaning tasks with wet or dry microfiber pads.
No Frills, Just Cleaning
The corded motor provides consistent suction, while the 20-minute UPS battery backup prevents falls during power interruptions. At approximately 1.3kg, it’s easy to position on the glass. The simple design means fewer things to go wrong.
Best Budget Option
For buyers who want to dip their toes into robotic window cleaning without spending over $200, the W120 is one of the most established budget options from a recognised brand.
