Title: Difficult to clean and very loud
Review: I loved this pet fountain when it first came because it holds a lot of water, which is great if you go on a short vacation. It was also easy to set up.However, the water gets dirty very quickly (I have two cats) and it's a pain in the butt to clean this machine. It holds so much water that it's heavy to carry to a sink and inevitably water spills on the floor. The sloping angle of the clear reservoir in the back makes it difficult to fill because you can't really set it down on anything - you have to hold it with one hand while filling it with water.Finally, the machine has become very loud over time. We try readjusting various components, which seems to make it quieter for awhile, but it's quite mysterious to me why it will suddenly starting humming very loudly.
