VisaPure briefly pauses after 20 seconds to let you know that you have to move to another zone. You can treat three zones for 20 seconds each before the appliance automatically switches off. This is to avoid overtreatment.
Note that this information is applicable for most cleansing brushes. The other heads—the Precision brush (SC6017) and Intelligent Sensitive brush (SC6011)—do have different treatment times and pauses.
