Sorry, there was a problem. Please try again later.This will entirely depend on the humidity in your area and the temperature its trying to maintain while combating with the ambient temps. When this unit was cooling my garage for over half a year on its own, i had to empty a 2.5 gallon bucket daily or semi-daily. If I didn't have a hose draining into a bucket then I might be fine for a few days or it might auto shut off same day due to having too much moisture in the container. It just depended on the weather. If you ever get a unit that just fills up water and leaks on the floor, its auto shutoff feature isn't working and I'd return it. After the house a/c was fixed, I still use this unit even now and I no longer need a bucket connected. The a/c portion only runs sometimes to maintain a temp that the house a/c already aims for and that means this unit isn't collecting as much moisture that it later has to attempt to disburse. My bedroom which is properly insulated, meaning its not as subject to the heat and moisture, and half the size of this garage has an LG portable a/c unit. I never had to have anything connected to its drain port. Never once emptied it. But some days the air in the room was noticeably humid. I just left the door open for a bit on those days. The other option was to get a dehumidifier or connect a hose to the LG unit which I didn't want to do. The way these things handle water is that as the a/c portion runs, it causes moisture from the air to collect in a container. When the a/c portion doesn't run and its just the fan portion, then it will blow air across the water collected and cause it to dry up. If it can disperse the water back into the air faster than it can collect it, then it won't need a hose for auto emptying nor will it need to be manually emptied. Since this Whynter unit was put in a closed in garage, it had to deal with more moisture than usual and since it was put in a garage that was almost twice its rating then it had to run more than it should have. That means it collected lots more moisture than it could disperse. The LG unit on the other hand was in a proper insulated bedroom that was around 375sqft while the unit was rated for up to 550sqft. So it was more than capable of operating without needing to worry about tending to the water. There was also a window a/c unit in the living room that helped empty moisture out of the air as well which is why on some days I'd leave my bedroom door open to rid excess moisture if it felt humid. I know answering this is very very late, but hopefully it sheds on light on things for others. In the right situation you don't need a hose nor need to drain any of these units, but in many/most situations you'll need to figure out how you want to go about emptying them. To be honest, I'd rather just be able to pull put a container, dump it and return it to the a/c unit. Using hoses and drain ports is rather annoying. But I'd take dealing with those over melting in the heat.
