interesting principle. It actually works. However, the absorption capacity is limited, and after cleaning the roller before being used must be dry. I would hope that instead of even 2 impose minor roles in the set (in this case, I prefer the Klass forensic lint roller before) choice for a 2nd + 3rd floor role would be offered. This would be helpful in the waiting period after cleaning in order to continue working quickly, if you have to remove the hair larger areas.
