Snail Cleaner by Dong Hun Seo from korea

It is not easy to clean bathroom, but it takes most of time to eliminate mold and fur frequented between tiles.
That is because people evade tile cleaning at time, and as its result it does not feel satisfied even after cleaning.
If something crawls tiles like a snail to eliminate dirt..
With 'snail cleaner' that crawls about tiles though I do not turn my attention, it will be easier to clean bathroom.
