Well, for the price I don't think they have this one figured out. If you rely on draining the water by hand with the little bucket thing they supply you will be draining it continuously all day long and getting water all over your floor in the process. You really must go out and get a drain hose and have it drain to the outdoors, however; the directions state that the hose has to be lower than the unit and since the drain is at the bottom of the unit it does pose a problem and the water backs up a lot. All that said, it does cool the room down... but you need to weigh the pros and cons and since it is EXTREMELY heavy it is not worth it to send back. This is the first disappointment I've had on overstock.
