This GWANZI 1/2HP automatic submersible pump quickly and reliably removes water from pool covers, hot tubs, ponds, basements and rooftops with a 3500 GPH capacity and hands-free float switch.

Heavy rain and melting snow can leave dangerous standing water on pool covers and outdoor surfaces. The GWANZI 3500GPH cover pump is built to run automatically, resist clogs, and deliver high-flow drainage when you need it most. Ready to use out of the box, it includes a preinstalled check valve, filter net, multiple adapters and a long power cord so you can begin protecting your property immediately.

How quickly will this pump clear water from a pool cover?

The GWANZI pump is driven by a 1/2 HP motor and rated for up to 3500 gallons per hour, moving large volumes of water fast. With a maximum vertical lift of about 35 feet it handles most residential drainage needs and shortens cleanup time after storms.

• 3500 GPH maximum flow for fast clearing
• 35 ft lift capability for flexible discharge locations
• 1/2 HP motor balances power and efficiency

Will it run automatically and stop when the job is done?

Yes — the integrated float switch activates the pump at approximately 2.5 inches of water and shuts off at about 0.75 inches, so it runs only when needed. That automatic on/off feature protects the pump from dry running and reduces the need for constant monitoring.

• Automatic start at ~2.5" water depth
• Automatic shutoff at ~0.75" to prevent dry run
• Set-and-forget operation for unattended protection

How does GWANZI prevent clogs and make setup easier?

The pump includes a removable debris filter net that keeps leaves, needles and other solids away from the impeller, minimizing clog-related downtime. A preinstalled check valve inside the adapter simplifies assembly and prevents backflow without extra parts.

• Debris filter net reduces clogs and maintenance
• Preinstalled check valve inside adapter for easier setup
• Three adapters included for common hose sizes and fittings

Can this pump be used for tasks beyond pool covers?

Absolutely — the GWANZI pump is a versatile utility tool. Its tool-free detachable base allows it to operate as a dedicated pool cover pump or a general submersible pump for basements, hot tubs, ponds and roof drains.

• Detachable base for multi-role use
• 25 ft power cord for extended reach to outlets
• Suitable for residential and light commercial applications
