6.0 hp 12 Gallon Shop-Vac 'exploding'

I purchased a 12 gallon Shop-Vac 6.0 hp to **** up water out of a trench and within 10 seconds of turning on the Shop-Vac it there was a loud pop and all suction ceased. I immediately turned off the motor and opened up the canister and found plastic and aluminum shrapnel everywhere. Nothing was actually sucked into the canister. I returned it thinking it might've been a rare thing but the exact same thing happened with my replacement. Both were brand new. Both the motors seemed to still work but the fan inside seemed to 'explode' right away leaving shrapnel everywhere and holes throughout the plastic.

Those type of vacuums are designed for light duty work around homes anyways. For commercial industrial work as you are doing you need a sump pump. We used to drop one in a 5 gallon (20 liter) pail, drill holes in the pail and suspend from a rope. (you can put screen around the pail covering the holes if needed too). Use a stiff hose to expell the water. You can change to a flat hose like a pool waste water hose or fire hose after the water is out of the trench.

Testimonial: "Thanks for the response! We actually cleared the trench using other methods so that isn't actually the issue now. I'm wondering what actually happened to the Shop-Vac because we do need one for sucking up occasional dust and similar things and I don't want to run into the same problem for the third time."

    It's possible that a piece of gravel got into the motor and shattered it... but it could also be just a bad design.

    Thats what i was thinking but both times we turned them on we didn\'t actually suck anything up into the Shop-vac. On both occasionals the nozzle was just sucking air and the fans exploded which leads me to think that its just poor design. I\'ve looked up to see if others have had this problem considering both shop-vacs we bought blew up but no one else had this issue.

SOURCE: Canister works, vacuum doesnt

There could be a break in the electric from the machine to the hose - or from the hose to the wand - or from the wand to the Power Nozzle - or it could be the motor is bad. 

Wiggle the cord at the Hose with it running- then go to the Wand - then to the Power Nozzle. You may find a break in the wires anywhere along the line.

unplug the Vacuum:

If you have a meter check to see if the reset is working - and last check to see if the motor will work removed from the Nozzle.

SOURCE: Craftman Canister Wet/Dry vac- Motor just stopped working

It is Repairable But, The parts will cost almost as much as a New Vac. I would just get a New Vac and save the Hastle and the Cash. The choice is all yours Though. Please Rate My Response! Thanks!

SOURCE: Capture bagless not sucking!

Both ends of the hose will unscrew, allowing you to push out hair and fiber clogs with a broomhandle. There is a coarse filter above the dustcup which will release with a 1/4 turn counterclockwise, allowing you to remove the hair and fiber bundles trapped in the inlet. The filter below the dustcup also tends to clog. Anything more and you have to start getting out the hand tools. bgovan445@live.com

Our BLB500, 12 gallon, 5.0 peak HP, Shop Vac won't come on.


From what I have heard, the switch on these units can sometimes be defective. Also, looking closely at the the AC cord may help determine if there is damage to it that should be repaired.

Shop-Vac 6.0 hp Peak 12 Gallon 'Exploding' after 10 seconds of use. Happened twice on two different brand new Shop-Vacs.


Since you said you were sucking water out of a "trench" I would bet there was some debris in the trench that impacted the impeller on the vacuum and caused the metal impeller to fragment, taking the plastic pieces with it. It is highly unusual for this to occur on vacuums if some type of debris, such as a small stone or piece of metal does not reach the high speed impeller/fan. I suggest using either a foam sleeve over the filter cage, or an old nylon stocking if you can get one, to screen out the debris that will cause this condition.

I have a 10 gallon Shop.Vac 3.0 but I don't have the instruction booklet. Do I take off the pleated "paper" filter to vacuum up water? Do I use the vac with no filter for liquid?


Yes you should remove the filter for liquids. If the filter is not removed the internal float stop will not operate correctly. This will lead to the liquid being drawn up into the impeller and around the motor.
However I still like to have something in place because in most instances the liquid you vacuum up will not be without some solids. So I like to use a foam insert. Places like Home Depot carries a universal insert that works great.
Hope that helps.

yes, the foam filter is what you should use, also make sure you remove any bag, or paper filter, the water would make it fall apart.

Can't install a bag for my Craftsman 16 gallon shop-vac


Well, good news, you don't need a bag! The trash just settles to the bottom of the bucket and you just dump it out.

I own one of these -- it has many little operational anoyances -- like wheels falling off, lid popping off, etc. If you run into these scenarios and want help on fixes, drop me a line.

Would you please rate my response. I think you'll see some icons at the bottom of the post to enter a rating.

thanks...

Shop Vac


You **** up water the same way as dirt. It's designed this way, hence the name wet/dry. Just be sure not to get the water in the very top of the unit where the motor sucks the air for cooling ventilation, if water gets in there it can burn up the motor. A little hard way, personal experience, speaking there.
