Fresh Water In. Used Water Out.
Lapwell Duo’s pump sits inside the enclosed fresh-water tank, separate from used drinking water. Every 6, 9, or 12 hours—whichever you choose—the bowl automatically drains and refills with fresh water. No recirculation. No used water returning to the fresh supply.
Another Fountain in the Trash?
We Know the Frustration.
You’ve tried different fountains. Dealt with pump failures. Scrubbed away slime, only to find it again. Many recirculating fountains share the same frustrations: reused water, hard-to-clean parts, and ongoing filter replacements. Lapwell Duo takes a different approach—with separate fresh- and used-water chambers, automatic water changes, and no replacement filters.
Frequently Asked Questions
Will my cat actually drink from it?
Will my cat actually drink from it?
Some cats take to Lapwell Duo right away, while others need a few days to adjust. Place it beside their current water bowl and keep both available until your cat is drinking comfortably from the fountain. Choose a quiet, familiar spot away from food and the litter box. Still hesitant? Contact our team—we’re here to help your cat settle into their new drinking routine.
Does the water flow continuously?
Does the water flow continuously?
No. Lapwell Duo replaces water on a schedule rather than circulating it continuously.
It fills the 304 stainless steel drinking tray from an enclosed fresh-water tank, then automatically drains and refills it every 6, 9, or 12 hours—depending on your chosen setting. Between cycles, the water stays still.
Conventional recirculating fountains send water from the bowl through a pump and filter, then back into the bowl. Saliva and hair can enter that shared supply. Lapwell Duo keeps used water separate, so it never returns to the fresh-water tank.
If your cat only drinks from running water, keep this in mind before ordering. Some cats adjust quickly to a still-water tray, while others need more time. Keep their current water source available during the transition, and contact our team if you need help.
How is Lapwell Duo different from PetLibro, Catit, or PetSafe?
How is Lapwell Duo different from PetLibro, Catit, or PetSafe?
Many conventional fountains recirculate the same water through a pump and filter. Saliva, hair, and debris can enter that shared supply, while buildup can collect in hard-to-clean parts.
Lapwell Duo uses two separate chambers to keep fresh water apart from used water. Its pump sits inside the enclosed fresh-water tank, and the drinking tray automatically drains and refills on your chosen schedule.
No recirculation. No continuously running pump. No replacement filters. Just scheduled water changes, with regular cleaning still part of the routine.
Do I need to buy replacement filters?
Do I need to buy replacement filters?
No. Lapwell Duo works without filters, so there’s nothing to replace and no ongoing filter cost. Its dual-chamber design keeps fresh water separate from used water, while scheduled drain-and-refill cycles refresh the drinking tray. Simply refill the fresh-water tank, empty the used-water chamber, and clean regularly.
How often do I need to refill the tank?
How often do I need to refill the tank?
Typically, every 10–13 days for one cat or 4–7 days for a multi-cat household. The exact timing depends on how much your cats drink and your selected refill cycle. Check the water level regularly and top up as needed.
How often do I need to clean it?
How often do I need to clean it?
Give Lapwell Duo a quick clean once a week—typically under 5 minutes. Rinse and wipe the stainless steel drinking tray, then empty and rinse the used-water tank. No replacement filters to worry about. Check for buildup regularly and follow the care instructions for deeper cleaning and descaling.

Give Your Cat Fresh Water, Every Refill
No filters. No recycled water. Just clean, fresh water your cat will actually want to drink.
The problem
That Slimy Buildup in Your Cat’s Water Bowl?
That’s what your cat is drinking. Traditional fountains keep pumping the same water around — and everything your cat leaves behind goes round with it.

That pink slime isn’t dirt
It’s Serratia marcescens. It lives behind your pump, inside the filter housing, in crevices you can’t reach. Cleaning the bowl doesn’t fix it.

Behind the bowl, it keeps coming back
Other fountains share water between the bowl, pump, filter, and cat, allowing saliva and hair to re-enter. Carbon filters don’t reduce bacteria. They host it.

Fresh water, one way
The pump only ever touches clean source water. The drinking surface refills from a sealed source every 6, 9, or 12 hours — whichever you choose. The slime never starts.

More than one cat?
Two Cats? Two Rooms? Two Fountains Work Better.
Many cat parents end up with a second Lapwell Duo. Here’s why it helps:
More chances to drink. Cats like water in more than one spot — one fountain upstairs, one downstairs.
Less guarding. In multi-cat homes, one cat can claim the only water bowl. A second fountain keeps the peace.
Never without water. Refill or rinse one while the other keeps running.
The real cost
Filters Add Up. Here’s the 5-Year Math.
A cheap fountain isn’t cheap once you add the filters.
| Lapwell Duo | PetLibro Capsule | Catit Flower | |
|---|---|---|---|
| Sticker price (one-time) | $179.95 | $39.95 | $29.95 |
| Filter cost (per year) | $0 | $96 | $60 |
| Replacement units required | 0 | 5-10 | 5-10 |
| Estimated 5-year total | $179.95 | $680-$1,080 | $350-$700 |
Fountain and filter prices are brand list prices as of October 2026. Filter costs follow each brand’s recommended replacement interval (PETLIBRO: a new filter every 2 weeks; Catit: every 2–4 weeks). Your costs may vary.
