If you haven't seen one yet, IRobot makes a self propelled vacuum that roams around the house sucking up dust and dander by itself so you can get other things done. Unfortunately, I find myself cheering my vacuum on as it glides through the house and following it around in amazement. Its a great purchase but sometimes it does need maintenance and you need to take it apart and clean the inside. (PS..Don't try to use it on shag carpet). It's great for everyday cleaning, I would not say DEEP cleaning. Check it out for yourself! And Hey...even the cat LOVES it!
