Chasing Hydro 4 Corded Robotic Pool Cleaner

The Chasing Hydro 4 Corded is the AC-powered version of the Hydro 4, a robotic pool cleaner built for medium to large pools. It runs from a pool-deck power control box through a 49.2 foot (15 meter) anti-snag swivel cable, so it cleans continuously with no battery limit. This makes it a good fit for larger pools and heavy debris loads where you want long, uninterrupted cycles.

Two turbine centrifugal pumps pull water through twin inlets at up to 320 liters per minute (5,070 gallons per hour). A dual-zone filter basket traps leaves and larger debris in the front and fine sand and silt in the rear. The unit cleans the floor, climbs the walls, and works the waterline, and you can steer it by hand or set a schedule from the Chasing app.

It is built for owners of medium to large in-ground and above-ground pools, up to about 1,614 square feet, who want continuous cleaning power without recharging between cycles.

• Dual Cleaning System: Chasing's twin water inlets and dual-zone filter basket pull in more water and trap more debris in a single pass.
  • Front zone captures leaves and larger debris
  • Rear zone traps fine sand and silt
• 320 L/min Dual-Pump Suction: Two turbine centrifugal pumps deliver up to 320 liters per minute (5,070 gallons per hour) of suction.
  • Strong pickup on floors, walls, and the waterline
  • Salt- and chlorine-resistant motors built for long service life
• Dual Active PVC Roller Brushes: Front and rear roller brushes scrub debris loose from every angle as the unit moves.
• Patented Waterline Cleaning: Side jets tilt the body up to 2 inches to hold a steady line along the waterline, cleaning about 25 percent more edge area than top-jet designs.
• Three Cleaning Modes and Ultra Boost: Choose Auto, Floor, or Walls and Waterline, with 1, 2, and 3 hour cycle options.
  • Ultra mode raises cleaning power by about 30 percent for heavy debris
  • Covers slopes, steps, and platforms
• Real-Time Underwater Control: Steer the unit, switch modes, or call it back from the Chasing app, even in the middle of a cycle.
  • Set weekly schedules, runtimes, and delayed starts
  • Over-the-air updates add features over time
• 4.1 L Dual-Zone Filter Basket: A large snap-out basket with 180 micron mesh traps about 40 percent more debris than standard filters and rinses out quickly.
• Easy Retrieval: When the cycle ends, the unit parks at the pool edge and floats to the surface for a simple one-touch pickup.

The Hydro 4 Corded suits homeowners with medium to large pools, both in-ground and above-ground, who want continuous cleaning with no runtime limit. Because it runs on AC power, it can run long cycles back to back, which helps with larger pools and heavy seasonal debris such as fall leaves.

It works on concrete, vinyl, fiberglass, and tile, and the 49.2 foot cable reaches across most residential pools. The manual 360 degree steering is useful for spot-cleaning, while the weekly schedule keeps the pool clean without daily attention.

The pool-deck power control box should sit in a dry, sheltered spot. For pool service professionals, continuous power makes the Hydro 4 Corded a dependable choice for back-to-back cleaning during a route.

Hands-on setup time: about 15 minutes. No charging is needed; the unit runs on continuous AC power.

1. Place the power control box: Set the power control box on the pool deck in a dry, sheltered spot, away from direct splashing.
2. Connect the cable: Attach the 49.2 foot tethered cable to the robot and the control box, and check the O-ring seal is clean and seated.
3. Install the app and pair: Download the Chasing app, create or sign in to an account, and pair the unit for scheduling and remote control.
4. Check the filter basket: Make sure the 4.1 L dual-zone basket is seated correctly before each cycle.
5. Place the unit and start: Lower the robot into the water, choose a cleaning mode (Auto, Floor, or Walls and Waterline) and a cycle length, then start.
6. Set a schedule: In the app, set a weekly schedule so the unit runs on its own.
7. Collect and store: When the cycle ends, the unit parks at the pool edge. Lift it out, rinse the basket, and coil the cable for tidy storage.
