From the designer Dave Hakkens:
“Dustball is a robot vacuum cleaner concept designed for public spaces. There are a lot of robot vacuum cleaners on the market but all designed for households. However they are fragile and not made to go over any cables, thresholds etc. This one had to be strong, industrial and flexible. However I did not want to give it an industrial/robot appearance.
Inspired by a hamsterball I came up with dustball. Usually there is no interaction with a robot vacuum. I created a little friend just rolling around and which you could push or kick in a direction to clean. It’s has no trouble with cables or anything like that, it’s strong, and when it rolls before your feet you just kick it out of the way.”
