HAPUP Cat Water Fountain, 1.8 L, with Dual Flow Modes and Four-Layer Filter

The HAPUP Cat Water Fountain is an automatic indoor drinking fountain designed to encourage cats to drink, with a 1.8 L (61 oz) reservoir and two adjustable water-flow modes.

• Arc-shaped faucet and sloped water flow — offer two ways for pets to drink.
• 120 mL (4 oz) reserve bowl — keeps a small amount of water available during a power outage.
• Four-layer filter and two replacement filters — help catch debris and improve water taste and odor.
• Three-position flow switch — lets you select the pump’s water stream.
• USB-connected DC 5V pump with three silicone suction cups — sits securely at the fountain’s base.
• 12-month maintenance service — includes a replacement pump if the pump stops working during the service period.

For indoor pets, a circulating fountain can make a water station more engaging than a still bowl. HAPUP combines a faucet-style stream with a sloped flow, so households can choose the water presentation that suits their pet. Its curved drinking design is intended to reduce pressure on a pet’s cervical spine, and the fountain is designed for cats and birds.

What water-flow options does the HAPUP Cat Water Fountain offer?

The HAPUP Cat Water Fountain has fountain and faucet modes, selected with a three-position switch on its adjustable pump. The fountain-style flow is designed to increase oxygen content in the water, while the faucet stream is intended to encourage pets to drink. The arc-shaped faucet and inclined slope provide the two different flow patterns.

• Choose between a fountain stream and faucet-style flow.
• The curved design is intended to reduce pressure on a pet’s neck while drinking.

How does the HAPUP Cat Water Fountain filter water?

The HAPUP Cat Water Fountain uses a five-cycle water system that directs larger particles from the upper bowl’s low-position drain toward a four-layer filter. The blue sponge pre-filter catches larger impurities, and white PP cotton captures hair and small debris. Ion-exchange resin softens tap water, while activated carbon helps remove unwanted taste and odor.

• Two blue replacement filters are included.
• The filter layers address particles, hair, water hardness, taste, and odor.

What happens if the HAPUP Cat Water Fountain loses power?

The HAPUP Cat Water Fountain has a separate 120 mL (4 oz) water-storage bowl that provides a reserve for a cat during a power outage. Its main reservoir holds 1.8 L (61 oz), an amount that can last for a week, reducing how often you need to refill it.

• The water tank has a smooth interior without extra bumps, making it easier to clean.
• The pump’s quick-release structure makes it easier to remove, install, and clean.

How does the HAPUP Cat Water Fountain pump connect?

The HAPUP Cat Water Fountain uses a low-noise, low-consumption DC 5V pump connected by USB. Three silicone suction cups help hold the pump at the bottom of the fountain, and its cable measures 78 in (1.98 m), excluding the pump head.

• The pump’s three-position switch adjusts the water stream.
• The manufacturer provides a 12-month maintenance service and a replacement pump if the pump stops working during that period.

The HAPUP Cat Water Fountain suits indoor cat owners looking for two flow styles, layered filtration, and a reserve bowl for power interruptions; its design also accommodates birds. It combines an adjustable USB pump, a four-layer filter, and a 1.8 L reservoir in one automatic drinking fountain.
