Operating Instructions

Powering On and Off

The Dyson V12 Detect Slim features a push-button power control. Press the power button once to turn the vacuum on, and press it again to turn it off.

Selecting Power Modes

Your vacuum has three power modes to suit different cleaning tasks:

  • Eco Mode: Provides the longest run time (up to 60 minutes) for lighter cleaning tasks.
  • Auto Mode: Automatically adjusts suction power based on floor type and dust level when using the Motorbar™ cleaner head. The LCD screen displays particle count in this mode.
  • Boost Mode: Delivers maximum suction for intensive spot cleaning and heavily soiled areas. This mode reduces run time.

To switch between modes, press the mode selection button located on the main unit.

Using Cleaner Heads and Attachments

  • Motorbar™ Cleaner Head: Ideal for deep cleaning carpets and hard floors. Its de-tangling technology automatically clears hair from the brush bar.
  • Laser Slim Fluffy™ Cleaner Head: Designed specifically for hard floors, this head features a precisely angled laser that illuminates microscopic dust, making it visible for thorough cleaning.
  • Combination Tool: Use the wide nozzle for general debris and slide the brush up for dusting delicate surfaces.
  • Crevice Tool: Perfect for cleaning around edges, narrow gaps, and hard-to-reach areas.
  • Hair Screw Tool: Features a conical, anti-tangle brush bar that spirals hair directly into the bin, preventing tangles. Excellent for pet hair and small spaces like upholstery and car interiors.

LCD Screen Display

The integrated LCD screen provides real-time information:

  • Run Time Countdown: Shows the remaining battery life in minutes and seconds.
  • Power Mode: Indicates the currently selected power mode (Eco, Auto, or Boost).
  • Particle Count (Auto Mode): In Auto mode, the screen displays a graph of the size and number of dust particles picked up, providing scientific proof of a deep clean.
  • Maintenance Alerts: Notifies you when the filter needs cleaning or if there is a blockage.

Maintenance

Emptying the Bin

Empty the bin as soon as the dirt reaches the MAX level. The bin capacity is 0.1 gallons.

  1. Hold the vacuum over a waste bin.
  2. Push the red lever down firmly to release the bin flap and eject the dirt.
  3. Close the bin flap securely until it clicks.

Cleaning the Filter

The HEPA filter is washable and should be cleaned regularly to maintain optimal suction. The LCD screen will indicate when the filter needs attention.

  1. Twist the filter counter-clockwise from the top of the main unit and remove it.
  2. Wash the filter under cold running water until the water runs clear. Do not use detergent.
  3. Shake the filter to remove excess water.
  4. Leave the filter to dry completely for at least 24 hours in a warm, dry place with good airflow. Do not dry in a tumble dryer, microwave, or near a naked flame.
  5. Once completely dry, reinsert the filter and twist clockwise until it clicks into place.
