Lawfery Wireless Cat Water Fountain Stainless Steel 3.2L/108oz, Battery Operated Pet Fountain with 3 Modes, Cordless Pet Water Dispenser for Cats and Dogs

I go this one and love it. Good battery life, easy to clean. https://www.amazon.com/dp/B0FFMJW46X I ditched the filters except for the one that goes in the pump itself. I clean it at least three times a week fully, but that takes very little time.
