Operating Instructions
1. Power On/Off and Mode Selection
Press the power button on the handle to turn the vacuum on. The LED display will show the current battery level and operating mode. Press the mode selection button to switch between standard and Turbo modes. Turbo mode provides maximum suction for tough dirt but reduces battery runtime.

2. Using the Motorized Floor Nozzle
The motorized floor nozzle is equipped with an Anti-Twist brush bar and LED lights. The LED lights illuminate the cleaning path, making dirt more visible. The Anti-Twist technology helps prevent hair and pet fur from tangling around the brush bar, ensuring consistent performance.

3. Using Accessories
Detach the extension tube or floor nozzle to use the vacuum in handheld mode with the specialized accessories:
- Crevice Tool: Ideal for cleaning tight spaces, corners, and edges.
- 2-in-1 Multi-Surface Tool: Use the dusting brush for delicate surfaces like shelves and keyboards, or slide it back to use the upholstery nozzle for furniture and fabrics.
4. Parking Position
The Hoover HF910H features a convenient parking position. When you need to pause cleaning, simply place the vacuum in its upright position, and it will stand independently. To release, press the quick-release pedal.

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your vacuum cleaner.
1. Emptying the Dustbin
- Ensure the vacuum is turned off.
- Press the dustbin release button and remove the dustbin from the main unit.
- Open the dustbin lid and empty the contents into a waste bin.
- Close the dustbin lid and reattach it to the main unit.
2. Cleaning the Filters
The Hoover HF910H uses a HEPA filter system. Clean the filters regularly to maintain suction power.
- Remove the dustbin.
- Locate and remove the pre-motor filter and the HEPA filter.
- Tap the filters gently to remove loose dust. For a deeper clean, rinse them under cold running water.
- Allow filters to air dry completely for at least 24 hours before reinserting. Do not use a dryer or heat to dry.
3. Cleaning the Brush Bar
Thanks to the Anti-Twist technology, hair tangles are minimized. However, occasional cleaning of the brush bar may still be necessary.
- Turn off the vacuum and detach the floor nozzle.
- Locate the brush bar release mechanism (usually a latch or screw on the side of the nozzle).
- Remove the brush bar.
- Use scissors to cut away any tangled hair or debris.
- Clean the brush bar housing.
- Reinsert the brush bar and secure it.
4. Battery Care
- Always use the original Hoover charger.
- Do not store the battery in extreme temperatures.
- If the vacuum will not be used for an extended period, charge the battery to approximately 50% before storage.
