The Gre Micro-Ventury Pool Cleaner is a hand-operated device designed to clean the bottom of your pool quickly and easily. It utilizes the Venturi effect, powered by a standard garden hose, to create suction that traps debris in its integrated filter bag.

- Do not use the cleaner if any parts are damaged. Contact customer support for replacement parts.
- Keep children and pets away from the pool area during cleaning operations.
- Ensure the garden hose connection is secure to prevent leaks and maintain optimal suction.
- This product is designed for pool cleaning only. Do not use it for other purposes.

Setup Instructions
- Attach the Handle: Securely attach a standard telescopic pool pole (not included) to the designated handle attachment point on the cleaner body. Ensure it clicks into place or is tightened firmly.
- Connect the Filter Bag: Place the filter bag over the outlet nozzle of the cleaner body and secure it tightly using the drawstring or elastic band provided. Ensure the bag is fully open to maximize debris collection.
- Connect the Garden Hose: Attach your garden hose to the hose connector on the cleaner. Hand-tighten the connection to prevent leaks.
- Prepare for Use: Before submerging, ensure the water supply to the garden hose is turned off.

Operating Instructions
- Submerge the Cleaner: Slowly lower the assembled cleaner into the pool, allowing it to fill with water and sink to the bottom.
- Turn on Water Supply: Once the cleaner is fully submerged, turn on the water supply to your garden hose. The water pressure will activate the Venturi effect, creating suction.
- Begin Cleaning: Gently guide the cleaner across the bottom of the pool using the telescopic pole. Move it slowly to allow the suction to pick up debris effectively. The brushes on the underside will help dislodge stubborn dirt.
- Monitor Filter Bag: Periodically lift the cleaner out of the water (with the water supply still on) to check the filter bag. If it appears full, turn off the water, remove the cleaner from the pool, and empty the bag.
- Finish Cleaning: Once the pool bottom is clean, turn off the water supply to the garden hose. Slowly lift the cleaner out of the pool.

Maintenance
- Empty and Clean Filter Bag: After each use, remove the filter bag, empty all collected debris, and rinse it thoroughly with clean water. Allow the bag to air dry completely before storing.
- Rinse Cleaner Body: Rinse the main cleaner body with fresh water to remove any chlorine or chemical residues.
- Inspect for Damage: Regularly inspect the cleaner body, brushes, wheels, and hose connector for any signs of wear or damage. Replace worn parts as necessary.
- Proper Storage: Store the cleaner in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
