You can find a handful of automatic dog paw cleaners that have bristles that rotate automatically by either using a lever or a battery-powered motor. The idea is that the process is easier since you won't need to manually rotate the cup. Our view, however, is that automatic paw cleaners are potentially unsafe, as your pet's fur could or skin could get caught in the workings. These models are rarely made by well-known or reputable manufacturers, which doesn't instill much trust. We recommend leaving automatic paw cleaners on the shelf.
