    • Pull the handle while pressing the lift away button to remove the body of the vacuum.

    • Remove the nine 16 mm screws using the Phillips #2 Screwdriver. Press on the side tabs in the middle of the panel and pull up to reveal the screw under the hose connection.

    • Remove the two 13.5 mm screws using the Phillips #2 Screwdriver.

    For Step 3, the text refers to 9 16mm screws, but the photo shows only 8 of them. You will find the 9th screw underneath the housing for the hose, the red tube in the center. Lift up carefully.

    On my vacuum there are not 9 Phillips head screws. There are 2 Phillips head screws and 7 star head screws. If you have any sense at all when you put your vacuum back together you will throw away these star head screws and replace them with Phillips head screws of like thread and length.

    There is no need to remove the rear wheel axle screws to remove the top.

    OMG Thank you CeCe! I was scratching my head looking for that last screw

    I can’t find the right bit for these screws. What size/type are they??? Mine are not star bits…

    Cant find the right tool -

    On other vacuum models Shark uses Torx security screws. The Torx/Star screwdriver/bit needs to have a hole in the end to accommodate the pin inside the Tork screw head.

    • Pull out the roller brush.

    The photos were perfect. Followed the directions perfectly step by step and I was able to reassemble and I had no screws left over! Thanks (59yr old Nana)

Any idea where to get a replacement control board for a NV501 machine? Brush motor checks out, but no power going to brush motor (though vacuum suction is fine).

Did you ever find a board, Dave?

Wife took all apart; quite impressed - but what voltage does beater motor run at? Gotta get a multimeter which are cheap now; Ck red and white leads to cute little motor; and if no power is reaching motor i’ll have the same question as DAVE… and also need to find part (and price of part) if it’s fhe motor …

I’m in the same boat here, Pretty sure my brush motor is going out. It keeps stuttering. I’ve cleaned everything but the filters. If cleaned filters don’t fix the problem, which I don’t know why they would, I need to buy a new brush motor. I don’t want to trash a vacuum only because of a easy to replace motor piece. If anyone finds where to buy it let us know!

Hi. I took apart per 8 step instructions hoping to find something obvious to repair ie. a belt, something pinched or mangled. I have never done anything like this before… all thumbs. Is there a step 9 or way to check roller function or motor function? Do I have to put it back together w/o the covers? 60 yr old neo-trician.
