Overall, the vacuum is pretty good. It’s easy to handle, being relatively light, and the battery life is also really good- I vacuumed 4 of the rooms in my house, and it only used a small fraction of the battery. Additionally, it cleans very well, and after testing it in my living room, the floor was completely clean. I don’t see anything bad with the vacuum-it has great battery life, is easy to handle, and has strong suction. Great functionality, and would be a good buy. I certainly don’t need my old vacuum anymore, and it’ll be replaced by this one.
