1. Can I use something other than the extremely overpriced and ridicously small amount of soap product? I got the largest bottle that was supposed to be "8-10 rooms" but the lady obviously didn't look at the label. It only does "4-8 AVERAGE sized rooms". I'll finish my basement with a tiny amount left...like maybe for my lone hallway. I don't want to go buy another bottle for a variety of reasons. I have some oxiclean that says it can be used. Is this one of those things you can sub out on or is this one of those things that will fall apart if it has something non brand name in it? 
2. This is going to take me forever. Am I filling this wrong? It says to fill until half the filter screen is covered. I'm doing that and having to dump and refill every 6-10 swipes of a room. I'm not doing large swipes either! It's frustrating to have to keep stopping.
3. Is it worthwhile to buy your own Rug Dr.? I'm staring at the sticker advertising that and it's sounding very appealing. It was ridiculous what I paid today to rent this stupid thing for one day.
