I have one of the cordless vacs. It works well at being a cordless, the size is great and it's easy to handle but...

It's made of really cheap plastic and has cracked in a few places.

Being bagless is good in that I can see what it's collected but bad in that when come to empty it the dust I'm allergic to goes everywhere. (If only someone would invent a bag to keep the dust in eh?).
