I unscrewed every screw on my Hoover SH40060 Multi Cyclonic vacuum, but something is still holding it together on the bottom. Any idea how can I take it apart? Thanks
Hi Nora, Did you managed to solve the problem? Please et me know. Thanks
Too late now! But there are 2 additional screws under the power button and cable rewind. Place a flat blade screwdriver edgewise under the back of the button and carefully pop it off. The springs will jump out. These belong on the middle cylinder. There is also a special security screw inside the hepa filter housing. Cut a slot in the middle of the blade of a cheap, 3/16" flat blade screwdriver to get this one out.
