I have Corgis. (double coats) I do believe in spending extra $$ for better quality but I have to tell ya, I purchased a Riccar Simplicity for around $300 and while I love the vac, the dog hair clogs it up and I spend a lot of time unclogging it! With this said, I went to Walmart in desperation one weekend and paid $89 for a Dirt Devil vac for "animals". I LOVE THIS VAC! It is bagless and you can see through the canister. It is amazing how much dog hair it picks up! I swore that my berber carpet was brighter after I used this vac. How long this cheapy vac will last is anyones' guess but I am truly happy with how it picks up the dog hair. It also has an "animal" hand roller brush attachments which is good for the stairs,etc.
