5 Criteria to Look For Before Buying a Tosima Window Cleaning Robots (2026)
Key buying criteria so you get the right fit the first time.
X1's dual-nozzle ultrasonic spray versus W5's standard auto-spray
The X1 represents Tosima's newer spray technology with dual-nozzle ultrasonic water atomization, potentially offering more even coverage than the W5's standard auto-spray system. Weigh this technology difference against the price step between models.
6400Pa adaptive suction rating on the W5
The W5 specifically markets a 6400Pa maximum adaptive suction rating, verify this spec matches your window weight and size needs, adaptive suction should adjust to maintain secure adhesion across varying glass thickness.
Visible water tank on the X1 for fill monitoring
The X1's 85ml visible water tank lets you monitor fill level at a glance, a practical convenience over a fully enclosed tank design where you can't easily check remaining water without opening it.
Triple safety system documentation on the W5
The W5 specifically markets a triple safety system, verify what this encompasses (typically tether support, power-loss protection, and edge detection) against your specific safety requirements.
Color option availability, a minor but real choice
The W5 is available in both white and black colorways at the same specification level, purely an aesthetic choice with no functional difference between the two.
