poor quality product. the dust canister release button broke after couple use.  the button is very flimsy and easily broken.  the worst part of it all was the terrible customer service and return/repair process.  the return for repair process is so difficult.  it probably is done so on purpose to discourage you from doing so.  if you return for repair you will be without a vacuum at least for three weeks.  i would not recommend this product.  i am going back to dyson.
