No suction through top of hose - HELP

disconnect the hose where it goes into the clear tube on top of the base.there will be a little flapper door there when yo take it off.open the door and take a coat hanger with the end bent over like a hook and pull the dirt clog out of there.but first take the dirt cup off and remove the filter,if its clogged with dirt you won't have any suction.try using the vacuum without the filter in the dirt cup.if you have suction then then thats your problem ,a cloggeds filter

it might just be clogged
