2. Safety Information
Please read and understand all safety instructions before using the appliance. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- This cleaner is suitable only for flat bottom pool floors. It is not designed for cleaning side walls, stairs, or for removing ultra-fine dust (nanoscale: 1 to 100 µm) or algae firmly attached to the pool floor.
- Always place the robotic pool cleaner into the water before powering it on. This protects the wheels and motors and extends their lifespan.
- Do not turn on the pool cleaner while it is charging. Ensure the cleaner is turned off and its charging ports are clean and dry before connecting to the charger.
- When placing or lifting the cleaner from the pool, orient its bottom towards the pool wall to prevent any possible scratches to the pool surface.
- After each use, thoroughly dry the area around the charging plug. Keep the plug dry even during storage to prevent corrosion and short circuits.
- Regularly check the filter for clogging, especially if suction power decreases or the cleaner's movement is impaired.

4. Setup
4.1 Initial Charging
Before first use, fully charge the robotic pool cleaner. Charging typically takes approximately 4-6 hours. Connect the charging adapter to a standard 110V outlet and then to the cleaner's charging port. Ensure the charging port is dry before connecting.
4.2 Nozzle Adjustment
The cleaner features two nozzles that thrust water to propel it forward. You can adjust the nozzle angles to control the cleaning path, optimizing it for your specific pool shape and any obstacles.
- For most pools with a flat bottom, adjust the nozzles to 0°-20° for a linear cleaning pattern.
- For pools with obstacles or irregular shapes, adjust the nozzles to 0°-40° to allow for more varied movement and coverage.

Adjustable nozzles allow for customized cleaning paths based on pool layout.
5. Operating Instructions
5.1 Placing the Cleaner in the Pool
Gently lower the cleaner into the pool with its bottom facing the pool wall. Ensure it is fully submerged before activating. The cleaner will remain on the surface for 15-25 seconds, allowing water to flow out from the nozzles, before sinking to the bottom.

The robotic cleaner ready for operation in the pool.
5.2 Cleaning Cycle
The PAXCESS Cordless Robotic Pool Cleaner operates for approximately 60-90 minutes on a full charge, covering pools up to 861 sq ft (or up to 1076 sq ft as indicated in some specifications). It moves at a speed of approximately 16 meters per minute (52.5 ft/min). Its powerful suction, combined with two large suction doors and a bottom brush, effectively traps and locks in leaves, dirt, and sand.

The cleaner's powerful suction effectively removes debris from the pool floor.

The cleaner provides up to 90 minutes of run time for efficient cleaning.
5.3 Auto-Docking and Retrieval
The cleaner is equipped with advanced battery detection technology. When the battery is low or the cleaning cycle is complete, the cleaner will automatically stop alongside the swimming pool shore. To retrieve it, simply pull up the floating handle. The cleaner is lightweight (approximately 12.1 lbs), making it convenient to remove from the pool.

The cleaner automatically docks at the pool edge when the battery is low.

Easy retrieval from the pool due to its lightweight design and quick water release.
6. Maintenance
6.1 Cleaning the Filter
After each use, it is crucial to clean the filter to maintain optimal suction performance. The cleaner's filter is designed for easy access and rinsing.

Rinse the filter thoroughly after each cleaning cycle.
6.2 Charging Port Care
To prevent corrosion and ensure proper charging, always dry the water around the charging plug after each use. Keep the charging port dry even during storage.

Ensure the charging port is dry and protected.
6.3 Storage
When not in use, store the cleaner in a dry place, away from direct sunlight and extreme temperatures. Ensure the battery is charged as needed for long-term storage.
7. Troubleshooting
This section addresses common issues you might encounter with your PAXCESS Robotic Pool Cleaner.
7.1 Common Questions & Answers
- Q: Why won't my cleaner sink to the bottom quickly?
A: It is normal for the cleaner to stay on the surface for 15-25 seconds. This allows water to flow out from the nozzles, enabling it to sink properly. - Q: Should I turn on the cleaner before putting it in the pool?
A: No. Always place the cleaner into the water before powering it on. This protects internal components and extends the product's life. - Q: Can I turn on the cleaner while it's charging?
A: No. The cleaner should be turned off and disconnected from the charger before operation. - Q: How should I put the cleaner into or take it out of the pool?
A: Always orient the cleaner's bottom towards the pool wall when placing it in or lifting it out. This prevents potential scratches to the pool surface. - Q: Water got into the charging plug cover, or the charging plug is corroded.
A: Ensure the charging plug area is completely dry after each use and during storage to prevent corrosion and short circuits. If issues persist, contact customer support.
