Remove the hose and check for a clog in the suction opening. If the hose is clogged, work the clog loose by massaging the clogged area and/or gently twisting the hose where it’s clogged until the clog works itself free. Make sure the door is latched shut. The door won’t latch without the bag being in place. Re-attach the hose (make sure it’s securely attached to the suction opening) and check for suction at the end of the hose with the attachments and foot off. Check the hose for cracks or holes. Check the variable suction control. If it’s set all the way to “min”, you may simply need to set it to a higher setting. Check the hose for clogs. If the hose is clogged, work the clog loose by massaging the clogged area. You can try gently twisting the hose where it’s clogged until the clog works itself free. If that doesn’t work, removing the hose from the unit and the extension wand will allow a broom stick to be pushed through to clear clogs from the hose. Now take the attachments and the extension wand off the hose and check for suction. If there’s suction at the end of the hose with the attachments off, but not with them on, the attachment may need to be cleared of clogs. The foot can be cleared by removing the access plate and brush. (See picture below.) Check the post-motor filter for clogs. The Post-motor Multi Level filter is not washable.
