CHOVERY CL3
Budget window robot with dual-side spray, 2,700–3,300Pa suction, and 30-min battery backup.
Mamibot W120-T
Our Verdict: An award-winning design that still holds up — basic but reliable, and one of the cheapest name-brand options.
The Mamibot W120-T earned recognition at IFA 2018 as a Top 10 Smart Device, and it remains a reliable mid-range option. Three AI cleaning patterns (Z, N, Z+N) provide systematic coverage, and the 3,000Pa suction keeps it firmly attached to glass surfaces.
Proven Design
The 75W motor at 24V provides consistent power through the cord, while the 600mAh battery backup maintains suction for 20 minutes during outages. Microfiber pads handle both wet and dry cleaning, and the 250 × 250 × 100mm body weighs a manageable 1.35kg.
Quiet Operation
At under 65dB, the W120-T is among the quieter window robots, making it suitable for use while people are in the room.
