If you're anything like me, no matter how awesome your vacuum is, it frustrates you to have to repeatedly unplug and replug your vacuum as you clean your whole house. Even if you live in a small studio (trust me, I have), you're bound to have to do so at least once to reach every nook and cranny. The answer to this is to attach a long extension cord (at very least 20 feet) to your vacuum, and plug it in whichever room sits in the center of your house. You may need to replug if your house has more than one floor. But regardless, this will speed up your cleaning time significantly. Just remember to wrap the cord in a neat coil when you finish, otherwise you'll have to deal with untangling it — and that's certainly not a time-saver.
