Vacuum cleaner help...?

coming from someone that's owned a vacuum cleaner store for 15yrs.,I have worked on all of them .The dyson is the best you can buy,I'll tell you why,there's nothing you have to buy for it ,no bags ,no belts ,and no filters.another thing about the dyson is there is a 5yr. warranty.I've studied all of them and there is nothing as durable as the dyson.I would buy the DC-17 Absolute, unless you want the extra attachments then get the DC-17 Absolute animal.hope this helps.
