My shop vac won't turn back on after emptying

The answer is simple...vacuums with filters allow air and anything finer than the size of the filter holes to pass through...if you hold a light over your bag and turn the vac on, you will see an explosion of fine dust coming from the bag...Vacs work on airflow, so the less air flowing through the bag, the less dirt you pick up...clogged bag = no airflow=no cleaning. Bagless vacs should have the filters cleaned after every use, and the canister emptied and washed. Buy a Rainbow to eliminate these problems.

problem with over heating motor ( possible short in windings )
have it checked out in a vacuum repair shop

The first place the "dirty" air enters is the top chamber of the canister where it traps the bigger stuff.

The canister has two clean-out doors so make sure you open them both (top and bottom) or you could have problems.

Nice thing about the Shark as it has a number of clean-out points starting at the base of the hose where it enters the bottom of the vac. to the beater brush (on the bottom of just behind the brush assembly). Good luck!

It's full, needs emptied. You have to keep the sponge like filter in to collect the water mist.

you have to clean the filter too. Use an air hose to clean it or brush it off with a stiff brush or you can wash it if it isn't paper. As a last resort you can get a new one.

Reasons for that to happen:
a) You have tilted the vac while vacuuming
b) Used the Rainbow without separator (basket like thing on the bottom of the motor)
c) Overfilled the rainbow tank with water (may have happened when shampooing with AquaMate)

Clean and install back the separator, remove HEPA, Set the Rainbow on empty water pan (with HEPA removed) turn it on for a while so everything will dry. Install new HEPA.

You will have to get a new HEPA filter (you can find them HERE)

Good Luck,

First of all Clean out the vacum cleaner . Empty canister and take filter outside and hit on something to get all dust out . Now wash canister and filter with vinegar water and let dry before using vacum again. You might try using carpet fresh for pet odors on carpet and empty and clean canister and filter regularly. I own a cleaning business and this is a hard problem to solve with all vac. cleaners. Good Luck!!

IT SOUND LIKE THE MOTOR WENT BAD OR IN SIDE THE PANLE A WIRE CAME LOSE

Stand in front of the vaccuum with the lable facing you, the 2 release levers are on the left and right sides, attached to the motor housing, which sits atop the tank/canister. Pull out and up on the levers, twist counter-clockwise, lift straight up and the motor housing will follow, leaving the tank/canister on the floor.
