The Hydro 4 Pool Vacuum is designed for pool owners who want a fully cordless, app-connected cleaning system capable of handling the floor, walls, and waterline of inground pools. With long battery life, dual turbine pumps, and smart navigation, it delivers a modern approach to pool maintenance without the hassle of cords or manual scrubbing.
This review explores its connectivity, cleaning performance, navigation technology, and overall usability to help you decide if it’s a good match for your pool setup.
Wireless Buoy Design for Steady App Connectivity
One of the unique features of the Hydro 4 is its wireless buoy design, which helps maintain a stable signal between the cleaner and the app—even when the unit is submerged.
Because the buoy floats above the water, it avoids the signal interruptions that commonly affect fully underwater devices. It also eliminates the need for connection cables, giving the cleaner more movement freedom throughout the pool.
Long-Lasting, Cordless Operation
The Hydro 4 operates completely cord-free, powered by a high-capacity 14,400mAh battery. This supports up to 3.5 hours of cleaning time, allowing it to handle both residential and commercial pools in a single session.
With no cord to manage, there’s less risk of tangling or snagging on pool features, and the cleaner can travel freely to cover all areas.
Dual-Power Mode
This feature helps adapt cleaning intensity to your needs, allowing the robot to adjust output depending on the type of debris or cleaning conditions.
Smart App & Cloud Control
Using the Poolmate Bot App, you can control the Hydro 4 through Wi-Fi or Bluetooth. App features include:
- Remote manual control- Cleaning schedules
- Mode adjustments
- Progress monitoring
Cloud integration adds the option to manage the cleaner remotely, even when you’re away from home.
For users who appreciate automation and flexibility, these controls provide a convenient way to manage pool care.
Comprehensive Cleaning Coverage
The Hydro 4 is designed to clean the entire pool, including:
- Floor- Walls
- Waterline
Its smart navigation system enables efficient paths to reduce missed spots and help manage pools of various shapes and materials—including vinyl, concrete, tile, and fiberglass.
This adaptability helps support thorough coverage across different pool styles.
High Suction Power with Dual Turbine Pumps
To manage debris both large and small, the Hydro 4 uses dual turbine pumps along with dual inlets, providing suction power rated up to 5070 GPH.
This design helps the cleaner pick up:
- Leaves- Hair
- Dirt
- Small debris
The dual-inlet configuration also supports stable wall climbing, which is essential for consistent waterline cleaning.
Large, Top-Loading Filter Basket
A key convenience feature is the 4.1L top-loading filter basket, which allows quick access for emptying and cleaning. It includes:
- A 180µm standard fine filter- An optional 50µm hyper-fine filter for smaller particles like dust, algae, and fibers
The large capacity minimizes interruptions during cleaning sessions, especially in pools with heavy debris.
Warranty & Support
The Hydro 4 comes with a 3-year warranty, offering added reassurance for long-term use. For troubleshooting, the manufacturer provides a Q&A resource and customer support.
