Query: Great power

I love this vacuum. It has a great deal of power and cleans very well. The only problem is that it needs a bigger holder for your dirt and also it can be messy to empty. I bought this because of my allergies and the canister must be emptied in to the trash and the dust still excapes. The cleaning power can't be compaired. I just empty outside.
