FAQs

To maintain your Dyson machine we recommend that you wash your filter(s) at least once every 3-6 months. Please see the video library below for a tutorial.

Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat. This usually happens because the filters need washing or your machine is blocked. If your machine cuts out, unplug it and leave it for at least an hour to cool down. Remember to turn the power off and unplug the machine before you check the filters and look for blockages prior to re-starting the machine.
