How to set up your Dyson vacuum

Charging your battery

It's important to charge the battery before using your vacuum for the first time. This helps the battery monitoring system's algorithm more accurately calculate remaining run time.

*The model and colour of the machine may differ from the one you own, but the process remains the same.

Essential maintenance

Watch our video guides on how to keep your machine performing at its best.

  • A user clearing a blockage from a dismantled machine.

    Checking for blockages

    If your machine detects a blockage, the motor will make a pulsing sound to alert you – and you won't be able to continue until the blockage is cleared. Remove the wand, bin and cleaner head to find and clear the blockage.

  • A user cleans the vacuum cleaner's bin with a duster.

    Emptying and cleaning the bin

    You can help to maintain suction by emptying the bin before the debris reaches the MAX line. Remove the bin from the machine to clean thoroughly.


Changing the battery

If you have an additional battery, you can switch batteries to achieve longer cleans. Simply press the red battery release button, and slide the battery off your machine. Your extra battery clicks into place. Watch the video.

Your Dyson Digital Slim Submarine™ wet and dry vacuum cleaner has a washable filter. We recommend washing it once a month to maintain optimum suction power.

    Wash the filter with cold tap water, gently squeezing the water out with your hands. Avoid using detergent or washing in a dishwasher or washing machine.

  • 4. Gently shake

    Fill the inside with water, cover both sides with your hands, and shake lightly. Wash until the water is clear.

  • Filter being placed in a well-ventilated area.

    5. Dry for at least 24 hours

    Allow the filter to air dry in a well-ventilated area for at least 24 hours, with the wide mouth facing down.

  • Filter left to dry completely for 24 hours.

    6. Let it dry completely

    Your filter must be completely dry before you return it to your machine, or it could damage the motor. Do NOT dry in a tumble dryer, microwave or near a naked flame.

The wet roller can be washed with a common household anti-bacterial detergent, diluted according to the manufacturer's recommended ratio. We recommend doing this after each clean to maintain hygiene.

Only the Dyson Submarine™ wet roller head should be used to pick up wet debris and liquid spills. Engineered with intelligent power diversion and mode detection, all aspects of wet cleaning are contained within the wet roller head. Water and debris is extracted from the roller into the waste tray, which sits directly behind the wet roller using Dyson’s new wet technologies.

The Dyson Submarine™ wet roller head is not compatible with any of our other vacuums, including a pre-purchased Dyson Digital Slim™ vacuum. To intelligently switch between wet and dry cleaning, this version of the machine has been reprogrammed. Our previous software is not compatible with wet floor cleaning.

The Dyson Submarine™ wet roller head has been engineered for hard floors.

We recommend replacing the wet roller every six months, depending on how often you use your machine, to help maintain optimum performance.
