Engineered Around How Cats Actually Drink—and How Owners Actually Clean

Every detail of the Cosari HydroSense Pro eliminates the daily annoyances of cheap plastic bowls and tangled wall cords.

120° Motion-Sensing Faucet Stream

The front circular infrared lens detects your cat up to 5 feet away and triggers a whisper-quiet 15-second arched stream that mimics the kitchen faucet they obsess over.

Up to 45 Days Cordless Freedom

Powered by a top-mounted 4,000mAh USB-C rechargeable battery. Place it in hallways or corners far away from messy kibble bowls—with zero cords for kittens to chew.

Hospital-Grade 304 Stainless Basin

Dishwasher-safe 304 stainless steel resists pink bacterial slime and prevents feline chin acne, while holding a shallow reserve pool of water between cycles.

68-Second Cord-Free Sink Teardown

No more fishing a slimy electrical wire through a wet plastic hole. The cordless spout tower and stainless tray lift straight off so weekly rinsing takes under 90 seconds.

How the Cosari HydroSense Pro Works

1. Detects Your Cat Within 5 Feet & Triggers a Fresh Stream

Cats instinctively distrust still water. As soon as your cat steps into the 120° × 1.5m infrared detection zone on the upright black spout tower, the 22dB pump delivers a gentle, splash-free faucet arc into the recessed stainless dish—or switch to Timed Mode for an automatic 15-second cycle every 15 minutes.

2. Lifts Apart in 3 Seconds With Zero Submerged Wires

Traditional fountains trap you into unplugging wall adapters behind furniture and threading a wet cord through the sink. With Cosari, the battery and electronics live inside the sealed top spout tower—just unclip the side latches, lift the stainless tray straight out, and rinse.

3. Filters Out Fur, Kibble & Odors Across 4 Stages

Every drop passes through a high-density pump sponge, non-woven fabric layer, coconut-shell activated carbon, and ion-exchange resin before cycling back into the 3.2L translucent smoky-grey reservoir—keeping water crisp and protecting aging kidneys.

Description

Why 304 Stainless Steel + Cordless Placement Matters: Cats naturally avoid water placed right next to their food bowl because stray kibble crumbs contaminate the dish, and porous plastic fountains breed bacteria that cause feline chin acne. Cosari combines a non-porous 304 food-grade stainless-steel basin with 100% cordless battery power so you can place fresh water anywhere in your home.

Dual Hydration Modes (Sensor + Timed Interval): Choose Motion Sensor Mode (triggers a 15-second arched stream whenever your pet approaches within 5 feet, conserving battery for up to 45 days) or Timed Mode (automatically runs a fresh 15-second stream every 15 minutes to attract timid cats).

Whisper-Quiet 22dB Brushless Pump & Dry-Run Shutoff: Engineered with a suspended 22dB low-voltage pump that won't hum against hardwood floors. If the 3.2L reservoir ever drops below the minimum refill mark, automatic dry-burn protection pauses the motor immediately.

5–7 Day Shipping & 30-Day Returns

Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.

30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.

2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.

Why Choose the Cosari HydroSense Pro?

4-Stage Kidney-Safe Filtration

Traps shed cat hair, stray kibble bits, chlorine odors, and heavy-metal ions so every drink tastes like fresh spring water.

22dB Bedroom-Quiet Operation

Engineered so the arched water stream lands smoothly inside the recessed stainless slope without sloshing or motor hum.

At-a-Glance Smoky Water Window

The translucent smoky-grey base lets you check water levels from across the kitchen without opening the lid.

Frequently Asked Questions

Does the Cosari HydroSense Pro have to stay plugged into the wall?

No. Once charged for 4 hours via the included USB-C cable, the built-in 4,000mAh battery runs completely cordless for up to 45 days in Motion Sensor Mode (in a single-cat home) or ~30 days in a two-cat household. You can also leave it plugged in if you prefer continuous power.

Are there any electrical wires submerged in the water that I have to fish through when washing?

Zero. Unlike traditional fountains where a wet cord threads through the bottom of the tank, the Cosari's battery and control module sit inside the sealed upright spout tower on top. When it's time to wash the fountain, the spout tower and stainless tray lift straight off in 3 seconds.

How does the motion sensor work, and will it scare a skittish cat?

The circular front infrared lens detects warmth and movement within a 120° cone up to 5 feet away. When your cat walks up, the 22dB brushless pump starts a gentle, silent arched faucet stream for 15 seconds and shuts off automatically after they walk away. Even skittish cats who bat at the stream on day one quickly realize it's their personal kitchen faucet.

Can my cat still get water if the battery runs out while I'm away for the weekend?

Yes. The recessed 304 stainless-steel drinking tray is engineered with a shallow catch basin that holds a constant reserve pool of clean water on top, even when the pump is resting between cycles.

How can I tell when it needs a refill or when the pump is low?

The 3.2L (108 oz) rounded-square base is molded from translucent smoky-grey BPA-free material, so you can see the exact water line from across the room. If the water ever drops below the minimum level, dry-burn protection automatically pauses the pump and flashes a status LED.

What is covered under the 30-Day Trial and Warranty?

Every order includes our 30-Day Picky Cat Hydration Trial—let your cats test it at home for a full month, and if they don't drink noticeably more water, send it back for a full refund. Your fountain is also backed by a 2-Year Pump & Battery Replacement Warranty.
