Any of you lovely people have one of these?

I’ve been coveting one for quite awhile — I love the fact that it doesn’t need filters, it’s supposed to be very easy to maneuver and get into small spaces, and having something that could keep up with Buster-the-walking-fur-factory would be amazing.

I’ve never been able to justify that huge price tag, but Kinja Deals just listed a certified refurbished one for $290 (obviously still expensive, but drastically cheaper than the normal price tag):

If you own one, do you like it? Have you found that it performs as promised?

And in general, should I be worried about buying certified refurbished?

ETA: Ordered it! Thanks so much for all the reviews.
