- Attach Brush Head: Securely attach the desired brush head (standard or corner brush) to the suction nozzle of the vacuum.

Operating Instructions
The BWT BC50 is designed for easy and effective pool cleaning.
- Power On: Submerge the vacuum cleaner into the pool water. Once submerged, activate the vacuum by pressing the power button. The unit will begin to suction water and debris.
- Cleaning Technique: Guide the vacuum slowly and steadily across the pool floor, walls, and steps. The strong suction power and integrated bristles effectively dislodge and collect sand, gravel, leaves, and other dirt.
- Monitor Debris Chamber: The transparent cover of the debris collection chamber allows you to visually check the fill level. Empty the chamber when it appears full to maintain optimal suction performance.
- Corner Cleaning: For hard-to-reach areas, corners, and niches, utilize the specialized corner brush attachment.
- Power Off: When cleaning is complete or the battery is depleted, remove the vacuum from the water and press the power button to turn it off.

Maintenance and Storage
Regular maintenance ensures the longevity and optimal performance of your BWT BC50 pool vacuum.
- Empty Debris Chamber: After each use, empty the debris collection chamber. The Quick Water Release Valve makes this process simple and mess-free.
- Clean Filter Inserts: Remove the filter insert and rinse it thoroughly with clean water. Ensure all trapped debris is removed. Allow the filter to air dry completely before reinserting or storing.
- Clean Brush Heads: Inspect and clean the brush heads regularly to remove any tangled hair or debris that may reduce cleaning effectiveness.
- Battery Care: For optimal battery life, avoid completely draining the battery before recharging. Store the vacuum in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, charge the battery periodically (e.g., every 3-6 months) to maintain its health.
- General Cleaning: Wipe down the exterior of the vacuum with a damp cloth as needed. Do not use harsh chemicals or abrasive cleaners.
