I'm working at a new school getting built and the swimming pool is being commissioned. With it being a building site the pool was obviously filthy. I was wondering how they were going to clean all the dust and debris that had settled on the bottom.
I went in today and this little thing was driving around and the pool was spotless! When it gets to the edge it even climbs up the walls and cleans them.
So cool to watch, until the boss came in
