text: No way to clean the water tank, small hole to drain water on. No way to open and clean the device - I suspect it would last alot longer if cleaning could be done on the unit. I did run it over night and got only a few drops of water. Not really humid or dry so I was expecting more moisture to be removed. I will use it to knock down humidity in our bedroom on really humid days. All that being said the price was right and the seller has awesome customer service.
