It should come as no surprise, but when hardware shows up at my doorstep for review, I try hard to find its breaking point.
The dock also features auto-emptying, mop washing, and heated drying. It sports a lot of small, clever details—like the see-through water reservoir integrated into the top of the dock so that you can easily see when it needs to be topped off. The shape of the reservoir also refracts light when full so that the water tube in the back of the tank disappears, which is a fun trick.
Noise-wise, the S1 Pro operates in the 50-60 decibel range. It's really only noticeable when it navigates over carpeting or rugs and activates the full 8,000Pa of suction power it has available. When it's a couple of rooms away, I have to stop and listen to tell if it's running . Is there"ick?" Yeah, you can't get around it. Even with ozonated water and heated drying, there's water left in the dirty water reservoir on the bot. That persistent moisture means some funky smells will be produced. However, you've got to go looking for them. It wasn't until I pulled the dirty water reservoir apart to clean it that I encountered any funk at all.
