Setup and Assembly
1. Assembly
Follow these steps to assemble your pool vacuum:
- Connect the filter tube to the vacuum body by twisting until secure.
- Attach the handle to the vacuum body.
- Connect the desired number of connection tubes to achieve the required length. The pole can extend up to 160 cm (approximately 5.25 feet). For longer reach in in-ground pools, the vacuum can connect to a standard telescopic pole (not included).
- Attach either the brush head (for general cleaning of steps and floors) or the vacuum head (for corners and tight spaces) to the end of the connection tube.

- Ensure the port is completely dry before plugging in the charger.

Operating Instructions
1. Powering On/Off
The vacuum features a water-activated sensor. Simply submerge the vacuum in water to activate it. It will automatically turn off after 60 seconds when removed from water to protect the device and conserve battery life.
2. Cleaning Your Pool or Spa
The Oxseryn OXCAHV05 is suitable for above-ground pools, in-ground pools, hot tubs, and spas.
- General Cleaning: Use the brush head for cleaning larger flat surfaces like pool floors and steps. Move the vacuum slowly across the surface to allow the 32 L/min turbo suction to effectively pick up sand, silt, and leaves.
- Targeted Cleaning: Switch to the vacuum head for precise cleaning of corners, crevices, and hard-to-reach areas where debris tends to accumulate.
