Yes, cleaning the filters is an essential part of routine maintenance for any Dyson owner. If you want your vacuum cleaner to continue working at top capacity and stay as good as new for many years to come, you need to wash the filters. Dyson generally recommends that users clean all of the filters in its vacuum cleaners at least once every three months. You may want to clean them more regularly if you tend to use your vacuum very often. To clean the filters, make sure the vacuum is turned off and unplugged. Remove the filters following the user instructions and then wash them in cold water only. Don't put them in a washing machine or use any kind of warm or soapy water. Let them dry out for at least 24 hours before replacing them.
