Hydro 4 – Powerful, Plug-and-Play Cleaning for Every Pool

The Water TechniX Hydro 4 is your powerful, plug-and-play robotic cleaner built to handle serious pool mess with zero fuss. With dual turbo pumps, intelligent navigation, and heavy-duty PVA brushes, it scrubs every inch—from floor to walls to waterline—capturing everything from fine dust to chunky leaves. With six smart cleaning modes, WiFi/Bluetooth control, and a 4.1L filter canister, it’s built for all pool types and backed by a 3-year warranty*. Just drop it in and let it do the dirty work.

What makes the Hydro 4 good at cleaning?
The Water TechniX Hydro 4 combines dual turbo pumps with intelligent navigation and rugged PVA brushes to deliver a deep, thorough clean. It scrubs the floor, climbs the walls, tackles the waterline, and picks up everything from fine dirt to chunky leaf matter—so you don’t have to.

Can it clean all pool surfaces?
Yep. Whether your pool is vinyl, fiberglass, concrete, or tiled—the Hydro 4 grips and cleans it all with ease, leaving no patch untouched 

• NOTE : Not suitable for pools with beach areas or depths less then 50cm

Does it save time and energy?
Big time. The Hydro 4 automates the entire cleaning process with multiple smart modes and auto-navigation. It’s energy-efficient too, reducing strain on your filter system while using only what it needs. Less effort, lower costs, cleaner pool.

What cleaning options does it have?
Plenty. Choose from:

• Regular Mode (2H) – Full clean: floor, walls, and waterline
• Fast Mode (1H) – Quick clean for light mess
• Ultra Mode (3H) – Heavy-duty deep clean
• Floor Mode (2H) – Focused bottom cleaning
• Waterline Mode (2H) – Targets walls and waterline
• Custom Mode (2H) – Configure to your liking via the app

How do I control it?
It’s got pre-set modes, but you can take over anytime using the Hydro-Cloud app via Bluetooth or WiFi. Adjust settings, start or stop cleans, or manually drive it from your phone.

Is the filter easy to empty?
Yes—its large 4.1L canister traps both fine and large debris. When it’s full, simply pop it open and rinse. No fiddling, no fuss.

Can it handle stairs and walls?
Sure can. The Hydro 4 has improved climbing tech, making it more agile on stairs and vertical surfaces for a more complete clean.

Is it built to last?
Absolutely. With ball bearing drive gears, waterproof motor seals, reinforced components, and a 3-year warranty*—it’s made for durability and peace of mind. 3 year warranty on main body, PCBA, power supply and adapter, floating cable, power cord and indicator light. 2 year warranty on drive motor and pump motor. 12 months on consumable parts – filter basket, track and roller brush.

What if I have a large pool?
No dramas. With a 15-metre cable and smart route planning, the Hydro 4 is built to cover up to 150㎡ efficiently—without missing a spot.

What if I have fine dust or big leaves?
The dual-stage filtration system captures both. Fine sand, dust, or chunky gum leaves—the Hydro 4 doesn’t discriminate.

Is it hard to set up?
Not at all. Plug it in, drop it in the pool, hit start. That’s it. No priming, no hoses, no apps required unless you want to go next-level.

Recommended maintenance : To keep your Hydro4 robotic pool cleaner running smoothly, we recommend regular maintenance of the spindle bearings and wheel bearings. These are located underneath the top cover at the end of each spindle and within each wheel. Simply remove the top cover and apply a light spray of a protective lubricant such as Inox, WD40 or CRC directly onto each bearing.  simple step helps prevent corrosion and ensures optimal performance. Following each cycle, empty debris from basket, hose basket and cleaner entirely then store until next use is required. 

Warranty : 3 year warranty on main body, PCBA, power supply and adapter, floating cable, power cord and indicator light. 2 year warranty on drive motor and pump motor. 12 months on consumable parts – filter basket, track and roller brush. Consumables such as tracks, wheel bearings and other wearing parts are to be purchased and replaced as required.
