Clarisonic Mia: Yes, I am one of the crazy owners of the $150 Clarisonic face scrubber, but to be fair, I received it as a gift and really like it. It's compact and cordless. The Mia and Mia 2 kits both come with a universal voltage charger.
Dirt Devil Kone Hand Vacuum: I've been a fan of Dirt Devil's Kone vacuum since college. It doesn't take up much space, it's perfect for picking up small items in the bedroom and bathroom (especially hair!). The shape is nice, and it doesn't look like a regular vacuum so I don't find the need to hide it in the closet. It's very portable and recharable as well.
ConAir Blowdryer: Almost everyone needs a hair dryer - some every day and some on special occasions. However often you need one, I'd suggest you get one with a retractable cord. Once I switched over to ConAir's Cord Keeper Styler, I was so happy to be rid of wrapping a cord around the dryer. This model and many other retractable cord dryers keep the bathroom free of cord tangles. (Images: as linked above)
