This might seem like a lot, but pre-motor filters are the first line of defence against debris clogging the motor.

and Dyson V15 have the same process for cleaning the filter.You should wash the filters once per month, unless the display shows a “Filter Needs Cleaning” warning..

As with the Dyson V10, you can remove the filter from the back of the device by twisting it in an anti-clockwise direction..Tap off loose dust into a bin.If you suffer from allergies, you should do this outside..

Angle the foam part of the filter downwards, then rinse the pleated paper section with cold water until the water isn’t murky..Next, hold the filter horizontally and rinse the foam part of the filter.

While rinsing, gently squeeze the foam from the inside to remove more dirt..

With the foam element facing upwards, fill with water and put your hand over the top.Dyson V11 – 60 minutes.

Dyson V15 – 60 minutes.As you can see, recent Dyson vacuums haven’t increased the maximum run-time beyond the 60-minute market.

This doesn’t mean the batteries haven’t improved though.The newest Dyson cordless vacuums are able to generate a stronger suction for this length of time.. Keep in mind that using the Turbo mode has a big impact on run-time.
