Charging the Battery

A full charge takes approximately 4.5 hours.
4. Operating Instructions

To start the vacuum, press and hold the power button located on the top of the main body. Release the button to turn off the vacuum. The vacuum operates continuously as long as the button is held down.
Using Cleaner Heads
Select the appropriate cleaner head for your cleaning task:
- Digital Motorbar™ XL cleaner head: Ideal for deep cleaning carpets and hard floors, with de-tangling technology for hair.
- Fluffy Optic™ cleaner head: Designed specifically for hard floors, its soft nylon and anti-static carbon fiber filaments remove fine dust and large debris, while the integrated green light illuminates hidden dust.

Suction Modes
The Dyson Gen5outsize offers multiple suction modes to optimize cleaning for different tasks and battery life. Use the mode selection button on the display to cycle through available modes (e.g., Eco, Auto, Boost). Auto mode intelligently adapts suction power based on floor type and debris level.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your Dyson Gen5outsize vacuum.
Emptying the Dustbin
Empty the dustbin as soon as debris reaches the MAX fill line. To empty, hold the vacuum over a trash can, push the red lever down firmly to release the bin, and then push it further to eject the contents. Close the bin base until it clicks securely.

Cleaning the Filter
The HEPA filter is washable and should be cleaned at least once a month, or more frequently if the vacuum is used heavily. To clean, twist the filter counter-clockwise to remove it from the main body. Wash under cold tap water until the water runs clear. Squeeze and twist to remove excess water. Allow to air dry completely for at least 24 hours before reinserting. Do not use a tumble dryer, microwave, or open flame to dry.
Cleaning Cleaner Heads
Periodically inspect cleaner heads for blockages or tangled hair. The brush bars can be removed for cleaning. Refer to the specific cleaner head instructions for detailed removal and cleaning procedures.
