3.1 Powering On and Off
To turn on the vacuum, press the power button located on the main unit. Press it again to turn off the vacuum.
3.2 Selecting Power Modes
The Dyson V15 Detect Absolute offers multiple power modes to suit different cleaning needs:
- Eco Mode: Provides the longest run time for lighter cleaning tasks.
- Auto Mode: Intelligently adapts suction power based on floor type and debris level, balancing power and run time.
- Boost Mode: Delivers maximum suction for intensive spot cleaning or heavily soiled areas. Note that Boost mode will deplete the battery faster.
Cycle through the modes using the mode selection button on the display.
3.3 Using the Detect Feature
The Fluffy Optic™ cleaner head features a precisely angled laser that reveals microscopic dust on hard floors, making invisible dust visible. This allows for more thorough cleaning. The LCD screen on the main unit displays the size and quantity of dust particles collected, providing scientific proof of a deep clean.
3.4 Attaching and Detaching Tools
To attach a cleaning tool, align it with the end of the wand or the main unit and push until it clicks into place. To detach, press the red release button on the tool and pull it away.

4.1 Emptying the Dustbin
The Dyson V15 Detect Absolute features a bagless dustbin. To empty, hold the vacuum over a trash can, push the red lever forward to release the bin, and then push it down to open the base and empty the contents. Close the bin until it clicks securely.
4.2 Washing the Filter
For optimal performance, wash the filter at least once a month. Twist the filter counter-clockwise to remove it from the main unit. Wash the filter under cold running water until the water runs clear. Squeeze and twist to remove excess water. Allow the filter to air dry completely for at least 24 hours before reinserting it into the vacuum. Do not use a washing machine, tumble dryer, or microwave.
5. Troubleshooting
If your Dyson V15 Detect Absolute is not performing as expected, please check the following:
- No Power: Ensure the battery is fully charged. Check that the charger is properly connected to both the vacuum and the power outlet.
- Reduced Suction: Check the dustbin and empty it if full. Inspect the filter and wash it if dirty, ensuring it is completely dry before reassembly. Look for blockages in the cleaner head, wand, or main unit and clear any obstructions.
- Cleaner Head Not Spinning: Check for blockages in the cleaner head brush bar. Ensure the cleaner head is correctly attached.
- Error Messages: Refer to the LCD screen for specific error codes or messages and consult the Dyson support website for detailed solutions.
