The AquaPurr Decorator series starts with this decorator base unit that contains the electronics. You can purchase this base unit with no decorative sleeve.
The AquaPurr Decorator never needs cleaning because it does not recirculate water and instead the AquaPurr flows fresh water from the faucet.
You never clean or refill the AquaPurr. There are no filters to buy either.
Your cat never drinks warm, stale, dirty water.
