Pros Good suction power. Good when not using the power brush attachment.
Cons Power brush attachment easily clogs with hair requiring constant clean out. Hair can get tangled in the motor spool preventing it from turning.
Summary Not worth the price given limitations of the power brush attachment.
Pros Great suction power, very handy for situations where you don't have to lug out the big Dyson. Awesome for sucking up crumbs, lint in electronics, dead bugs, in between sofa cushions and quick clean-ups.
Cons Pricy. They the charge doesn't last for more than 5 minutes, but this isn't a con, because truthfully, if you were to use the vacuum for more than 5 minutes, then you really should have lugged out the big vacuum instead.
Summary Awesome product, one of the handiest Dyson products where the means justify the cost.
