PetSafe Drinkwell Trinkbrunnen 360 für Katzen und Hunde, BPA-freier Kunststoff, Duales Filtersystem, 3,8 L Wasserkapazität

Q: how often do you need to replace the filters?

I've been using it without the filters without any ill effects. The manual says that's OK. I take it apart about every 3-4 days and give it a thorough cleaning; only takes about 10 minutes or less. About once a month, I take the motor out and clean all the removable parts. I have 2 cats and a small dog using the fountain.

Q: Is there an on/off switch? Also, what is the diameter measurement?

There is no on/off switch, but it is simple enough to unplug. It's about 12-1/2 inches in diameter. There's a splash pan available for this fountain, too, that is about 19 or so inches in diameter. Depending on how messy your pet is, it's a good investment. (My Persians soak water up in their facial hair - those lovely Persian ruffs - and tend to make a mess trying to avoid getting water on themselves. Ha!)

Q: how long is the cord?

It's around 4 or 5' and the cord detaches in the middle so you don't have to unplug from the wall and carry the heavy plug.

Q: Has anyone compared the plastic vs metal vs. ceramic? Is stainless better than plastic due to potential leaching?

I've had both plastic and stainless. The metal is more durable than the plastic, but I have hard water so both collect sediment like crazy. My biggest problem with both models has been sediment building up in the diverted at the top of the fountain. I've replaced the pump a few times and always stick with the stem filter schedule, but I can only get a slow stream of water from one of the spouts now. I've had it for 3? Years. I'd buy a new diverted assembly but it's not one of the replaceable parts.
