Dear Nico Chong, we attach great importance to the opinions of every customer. Your suggestions are the key to our progress. So the continuous water discharge mode has been added to our subsequent new models E1 lite and D1 pro. The wireless + intelligent recognition water discharge of the Pet water fountain E1+ is its highlight. The purpose of its intelligent water discharge function is to attract cats to drink water, so that cats can drink enough water in a healthier day. At the same time, it avoids the problem of excessive filter consumption or excessive power consumption caused by continuous water discharge. Please feel free to contact us if you have any other questions.
