One of my Christmas presents was a tiny shark vacuum that I haven't opened yet, but I think it may make cleaning a little easier.
The Shark Cordless Floor and Carpet Cleaner
Its pretty neat, but it has to charge for 24 hours before the initial use. It's using an Ni-Lithium battery so the charging instructions are very specific, but the portability is great. I have no idea why I never bothered using it, lazy me, but after assembly it weighs less than half of my real vacuum. It will probably save my back lots of aches, silly me. I think this is the only time in my life I have every been excited about vacuuming!
