Previously I had the gravel cleaner from Dennerle, who was put together in oodles items and I am quite a while rather annoyed them. Then I happened to be in the pet store saw a demonstration video of JBL model and was very excited. Ordered and tried yesterday. The enthusiasm continues. The Dennerle Gravel cleaner attracts too many stones with high that the ground at some point inevitably lands in the bucket when you are not careful. The floor cleaner JBL makes this not that easy just sucks all the dirt out of the ground and the ground stays nice and there where it belongs. Top product, I highly recommend it.
