How long does the battery last on a charge?

Oneisall rates it at up to 60 days per charge. Runtime drops with heavy use and higher flow modes, so expect shorter stretches if several pets drink often.

How often do I change the filter?

Oneisall recommends every 2 to 3 weeks for healthy water. The standard pack includes 3 filters; the extended option adds 8 more for about 6 months of changes.

Is it good for cats and small dogs?

Yes. The 3.5L basin and three flow modes work for cats and small to medium dogs. The low profile and quiet pump suit shy drinkers.

How does it compare with a plug-in plastic fountain?

It removes the cord pets chew and uses stainless steel instead of plastic, which resists bacteria and odors better. The trade-off is recharging the battery and buying filters regularly.

The fountain, its pump and filter setup, and 3 filters in the standard pack. The extended option adds 8 extra filters.

The stainless steel basin wipes and rinses easily. Disassemble the pump and filter housing regularly, and replace the filter on the 2 to 3 week schedule.
