Query: VERY VERY DISAPPPOINTED

Was so excited to purchase my very first vacuum especially after reading all the reviews and growing up with only Electrolux in the house. Great lightweight canister but NOT great with dog hair so need to go bagless. Used only twice and had to use a new bag each time so in no way is it practical. Missed the deadline by one day to return so quite pricey to be stuck with something so disappointing!As I continue to use this after my intital review, I am more and more disppointed. I have a 2 bedroom 1928 cottage and 1 dog yet unable to vacuum the entire house without changing the bag.......AAARRRRRGGGGGHHHHHH..... VERY VERY FRUSTRATING
