Query: Lightweight and powerful

Very nice carpet cleaner. Very lightweight and yet still powerful. Did a nice job on carpeting that had not been cleaned for too many years. The only downside I have seen is that, while the receptacles are easy to remove from the machine, it is difficult to take them apart to fill or empty. It feels like I have to force the latches too much -- since they are plastic, I am afraid they will snap. That is the only downside I've seen on this otherwise easy-to-use product.The product came in a day, too -- even using standard ground shipping. A very nice surprise.
