I purchased my Dyson 3 about six months ago.  I use every attachment except the pet brush frequently. I have purchased three Dyson vacuums over the past 15 years and this model is the best one yet.

I especially love the 3 floor levels on the vacuum head and how easy it is to change levels.

I love all the attachments and have also found attachments from previous models fit this vacuum too. Every attachment makes it easier to use and makes me feel like an expert cleaner.

The amount of suction on the Dyson 3 is phenomenal. 

The only thing I can think of that would make my Dyson 3 better, would be if Dyson would make an attachment to clean blinds.
