                How often should I run a Deep clean cycle?
This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the MyDyson™ app. Running a Deep clean cycle helps to eliminate odours that occur through poor maintenance.
