Common questions
How does a cordless fountain work?
It runs on a rechargeable internal battery rather than a mains cable, so you can place it anywhere in the home without needing a nearby socket. You recharge it periodically depending on use.
Is it hygienic?
Yes, it uses 304 stainless steel, which resists the biofilm that builds up on plastic fountains and is easy to keep clean.
How long does the battery last?
It varies with flow settings and how often the pump runs, but the cordless design is the main appeal, letting you site it away from sockets. Check current battery figures before buying.
