This dehumidifier can remove up to 15 gallons per day of water from rooms up to 800 square feet. This machine pumps itself out every 15 minutes, so the drainage hose must be put somewhere it can drain at all times. A floor drain or bathtub works great for this and the dehumidifier automatically pumps out every 15 minutes. The unit weighs 80 pounds and must be kept upright at all times. This item requires a standard 110v power supply.
