Input:
The product came with two batteries.  One is fine, it runs for a long time, the other only lasts about 30 seconds before it's out of juice.  We use the same recharger for both so don't understand why one works and the other doesn't.

Other than the vacuum works fine.  It works well on carpeting as well as tile floors.
