Vacuum Options

[Act One Cleaning]

Js, if you are open to suggestion, try buying a good used backpack:  Proteam, Rubbermaid and so on.  You'll find they are very good at sneaking into and around obstacles and fast.  Listen to the suck and you'll know how to position the head for best effect.  I use them for everything from carpets to dusting lampshades.  

I also use an old Kirby for flogging the daylights out of carpet.  Just try things that make sense to your situation; rent if you can before buying, snap up craigslist deals, buy new when you are ready.  Just common sense, really.  Good luck!
