PETKIT EverSweet 3 Pro Review: The Ultimate Smart Water Fountain for Cats and Small Dogs

As a pet parent who's gone through countless water fountains over the years, I've seen my fair share of disappointments. My cats would either refuse to use them, or the fountains would become breeding grounds for bacteria within days. That all changed when I discovered the PETKIT EverSweet 3 Pro. With an impressive 99.96% bacteria elimination rate thanks to its wireless UVC pump, this isn't just another pet fountain—it's a technological leap forward in pet hydration. But at $79.99, is it worth the premium price tag? I spent three weeks testing this sleek device to find out if it lives up to the hype.

The PETKIT EverSweet 3 Pro elevates the humble pet water bowl into a sophisticated hydration system. Its wireless UVC pump technology continuously sterilizes water, eliminating 99.96% of bacteria without any chemical additives. This foundational feature ensures your pet receives clean water throughout the day. Operating at under 25dB, this fountain runs more quietly than a whisper, making it ideal for noise-sensitive environments and pets. The silent operation prevents disruptions during night hours while maintaining constant water circulation. The smart connectivity features transform routine pet care through Bluetooth integration with the PETKIT app. This allows real-time monitoring of water levels and filter status, giving pet owners precise control over their pet's hydration needs. Aesthetically, the fountain features a modern, minimalist design that complements contemporary home décor rather than detracting from it. The combination of 304 stainless steel with BPA-free ABS plastic creates a premium appearance that stands apart from typical plastic pet accessories.

The EverSweet 3 Pro features a premium 304 stainless steel drinking surface that provides superior hygiene compared to plastic alternatives. This medical-grade steel prevents bacterial growth and remains rust-resistant even with constant water exposure. With dimensions of 7.68 x 7.68 x 5.83 inches, the fountain maintains a compact footprint that fits comfortably in kitchens, bathrooms, or living spaces without dominating the area. Despite its modest size, the fountain holds a substantial 1.35L (45 oz) of water, reducing the frequency of refills required. The thoughtful engineering extends to practical considerations like cable management, with design elements that minimize potential hazards from curious pets chewing on cords or humans tripping over them. For maintenance purposes, all components detach easily, allowing thorough cleaning of individual parts. Weighing 2.82 lbs when empty, the fountain provides sufficient heft to remain stable when pets drink enthusiastically. The quality materials—304 stainless steel, BPA-free ABS plastic, silicone, and PP—contribute to both durability and safety.

The EverSweet 3 Pro connects directly to smartphones via Bluetooth, eliminating the need for complex Wi-Fi setup procedures. This straightforward connectivity enables the PETKIT app to display critical information about the fountain's operation. Water level monitoring provides peace of mind by alerting owners before the fountain runs dry. The system tracks filter usage and provides timely replacement reminders based on actual water processing rather than arbitrary timeframes. The fountain offers three distinct operating modes to accommodate different situations:

• Smart Mode automatically adjusts water flow based on usage patterns and time of day
• Normal Mode provides consistent water circulation
• Night Mode reduces operational noise and dims lights for undisturbed sleep

Usage statistics tracked through the app help owners monitor their pet's drinking habits, potentially identifying changes that might indicate health concerns. The system also monitors power consumption, implementing energy-saving features to minimize electrical usage while maintaining just 2W of power draw.

The 4-stage PETKIT Filter 3.0 forms the core of the fountain's purification capabilities. This comprehensive system begins with a primary filter that captures hair, debris, and larger particles before they can circulate through the system. The second layer contains activated carbon that effectively eliminates odors and improves taste by absorbing chemical impurities. Following this, an ion exchange resin reduces heavy metals and excess minerals that could potentially harm pets over time. The final filtration stage employs a dense cotton layer designed to trap microscopic impurities, ensuring water reaches optimal purity before your pet drinks it. The app includes a filter replacement indicator that tracks usage and alerts owners when replacement is necessary. Depending on water quality and the number of pets using the fountain, filters typically require replacement every 2-4 weeks. This regular maintenance ensures consistent water quality and protects the pump mechanism from debris.

The EverSweet 3 Pro prioritizes user convenience with tool-free disassembly that facilitates weekly cleaning routines. Most components are dishwasher-safe (excluding the pump), allowing for thorough sanitization with minimal effort. During operation, the fountain maintains its ultra-quiet performance below 25dB, making it suitable for continuous use without creating disturbances. Clear LED indicators display power status and water levels at a glance. The USB power connection provides flexibility in placement, while the efficient 2W power consumption keeps operating costs negligible. Safety features include automatic pump shutoff when water levels drop too low, preventing motor damage. For optimal performance and hygiene, weekly cleaning removes accumulated pet hair and biofilm. This regular maintenance extends the lifespan of both filters and the fountain itself.

Flowing water naturally attracts pets and encourages increased water consumption, potentially preventing urinary tract issues and kidney problems that commonly result from dehydration. The integrated UVC sterilization technology continuously eliminates harmful bacteria without introducing chemicals that could harm sensitive animals. The comprehensive filtration system removes impurities that may contribute to urinary problems, while the stainless steel drinking surface prevents chin acne that some pets develop from plastic bowls. Constant water circulation prevents stagnation and inhibits bacterial proliferation that occurs in standing water. The fountain's whisper-quiet operation ensures that noise-sensitive pets aren't deterred from drinking, while the elevated design reduces strain on your pet's neck compared to floor-level bowls. These thoughtful features address common obstacles to proper hydration in domestic animals.

Currently available at Chewy with a 30% discount, the EverSweet 3 Pro retails for $55.99 (reduced from the standard $79.99). This initial investment is supplemented by ongoing maintenance costs, primarily replacement filters priced between $7-$9 each. Annual maintenance typically amounts to $70-90, including regular filter replacements. However, the energy-efficient design consumes minimal electricity, adding only pennies to monthly utility bills. The durable construction using premium materials ensures longevity, spreading the initial cost over the years of service. When compared to basic fountains, the EverSweet 3 Pro commands a higher price point justified by its advanced features, smart connectivity, and superior materials. Beyond convenience, the health benefits may potentially reduce veterinary costs associated with dehydration-related conditions, offering long-term economic advantages.

After weeks of testing the PETKIT EverSweet 3 Pro with my two finicky cats, I'm genuinely impressed by its thoughtful design and innovative features. The combination of silent operation, effective filtration, and UVC sterilization addresses virtually every complaint I've had with previous fountains. While the price point is higher than basic models, the current 30% discount makes it a compelling value proposition. For pet owners who prioritize their companions' health and hydration, this fountain represents a worthwhile investment that both you and your pets will appreciate for years to come.
