Securing the correct ends of the detachable hose to your unitUpdated a month ago

There are two very different ends of your detachable hose for your Professional PLUS FM-02 model or ULTRA FM-04 model. Note the shape of the blue release button on each end. 

• The end of the hose with the CIRCLE shaped blue release button snaps securely into your unit.
• The end of the hose with the OVAL shaped blue release button is where you will snap your attachments on.
