Input:
I bought this for our low pile carpet when a broom wasn't enough. The extra battery is VERY convenient and it's pretty powerful for our area rug and some surrounding hardwood. We can definitely hear/see it working, but the proof is in the canister when I dump it out about once a month; just a mess of dust, hair, and debris. The filter is very easy to maintain, just wash it with a little dish detergent and leave it out to dry overnight before putting it back together.

I don't use the handheld function very much since we have a separate hand vacuum, so sorry can't say anything about that. I also don't continuously charge the battery, just keep the other one charging and switch them when the current one is low on battery. That being said, I swap it out after about 2 uses on our 8' x 10' rug, which I vacuum about twice a week, to give you an idea. It's not too loud in my opinion, but the cat disagrees.
