iPettie Runway Cordless Cat Water Fountain

3 Fountains I’ve purchased: 1) Drinkwell zen corded fountain about one gallon,round stainless steel bowl. Large bowl with downspout in stainless steel,immersible pump, flimsy carbon filter, plastic housing, cord only means continuous stream, might be too noisy for bedroom. I upgraded it with a trimmable larger carbon aquarium filter and nylon drawstring bag over the pump. Requires a brush to clean the tubing and pump housing. A juggle to assemble and lot of surfaces to clean. Manual fairly good on cleaning. I’ve had pump several years! No rust as of yet. With the upgrade carbon & nylon bag around the pump, I’m cleaning every two weeks in outdoor, partially sheltered location. Easy to top off. Nice capacity. 2. ipettie (rechargeable ensure you select this if desired there is also a wired version which I got) fountain 4 litters (1.1 gallon). Stainless steel square bowl more compact than a round bowl; immersible pump includes long cord (5’ usb-c cord length), wired version includes the adaptor!!! and brush for cleaning (immersible pump with tubes will be some extra cleaning there); some pre-filter sponges. Very easy to assemble, and only the continuous spray plug-in is on apparently I got the WIRED version by mistake when I selected the extra filter package. The 5’ cord and included adaptor makes that doable. Has a plastic inner shelf to hold the filter. A little SLOW topping it off, could be deeper; like the level viewport although hard to see that at night even with light. Just got this one—So far this is the best fountain for my six cat household with 1.1 gallons as cats need 1 cup per cat! I refill with RO water. My cats do drink out of this more often than the red plastic one, I think continuous flow might taste better & I like the continuous water flow it’s got a comforting ‘white noise’ to it. Note: I have it on a tray with a lip to contain any spills. 3. Pawaii rechargeable small red compact all-plastic fountain. Impeller external to pump, battery and controller, 6-stage filter snaps neatly in place would be good for poorer water quality or purchased distilled water; short cord (6”) for recharging 🙄. No adaptor. Easy to clean and assemble. Too small for 6-cat household. Water Top-off easy. Battery lasted me one day to two weeks. Plugs into red covered receptacle on back top of controller. Highly variable charging capacity probably due to how often my 6 cats walked in front or drank from it, because the flow is activated by a sensor & also comes on every hour. Controller not well covered in manual; resetting the warning filter light takes a very quick tap four times to reset (I was pressing that too long). If you reverse the plug, it will charge (blinking green) but after completion, it will not flow—never goes to “blue” light stays on the steady green light. Then, You have to reverse the plug to get that flow working again after recharge, for the normal blue light. Don’t know if the UV light really works at all (it’s under the unit directed to the water). Best for location close to plug (6” cord) and less frequently used, like bedroom. Not sufficient for my six cat household as the ONLY fountain. Had this 3 months with a lot to learn! Have it on a tray in bedroom, where use is limited & to contain any spills. Fairly quiet. With it’s intermittent rain noise it can actually be worse than a continuous ‘white noice’ I’ve noticed in the bedroom setting.
