My wife and I had been looking at cordless wet dry vacuum cleaners for a while but had been hesitating to buy one because of a couple of concerns: 1) cleaning power; 2) battery life. We finally purchased this one because it has the highest battery capacity - 4900 mAh! The package was received in sound conditions - no dent, no damage, and no missing parts. The machine was very easy to assemble, took me less than five minutes. The battery was pre-charged at about 50% so the cleaner can be used right away. But in order to test the full battery life, I left it on the charging base overnight. It turned out working GREAT! After cleaning the whole house (about 45 minutes), the battery bars still had about 1/3 left, so I think battery life should be longer than the specification 60 minutes. In terms of cleaning power, this machine exceeded my expectation. I didn't expect it to perform over traditional mops because after all the cleaning force is only from the rolling brush which I thought was not as strong as a mop operated by a human force. I was surprised after I saw dark gray water in the dirty water tank. I mop the floor almost every other day so I thought the floor was very clean. The self-cleaning is another feature I like very much. After three self-cleaning cycles, the water in the dirty water tank became crystal clear and the roller was just like new. Overall, I am very satisfied with this machine. Highly recommended.
