CRAFTSMAN WET/DRY PUMP VAC 16 gal/ 6.5 HP use
4 layers of filters for dry vacuuming
QUESTION: My apologies if this is not the appropriate group for this topic, but I
have no idea what group is? Any suggestions for the right group to ask
this, gratefully accepted.
Unfortunately there is no "rec.wetdryvacs.tech"
I have a serious problem w/ my CRAFTSMAN WET/DRY vacuum.
It constantly emits dust when in operation. The dust smells like the
burnt dust that goes through any vacuum when it is leaking dust & going
through the motor.
I have numerous allergies & bought this model because it advertised
that a HEPA filter was available for it.
It is a:
CRAFTSMAN WET/DRY PUMP VAC 16 gal/ 6.5 HP
Model #86773-29 (LOOKS LIKE A RED & BLACK 'R2D2')
For dry vacuuming I have always used 4 layers of filters, per the
owners manual.
The CRAFTSMAN Disposable Filter Bag 917893
The CRAFTSMAN professional HEPA filter 917886
The CRAFTSMAN Cartridge Filter (Black Stripe) 17884
The CRAFTSMAN Foam Sleeve
17888
I've used it twice for wet vacuuming. Both times I've carefully
followed the Owners Manual & also meticulously cleaned it out.
I'm hoping to find suggestions for a solution for its dust problem. Or
at least an explanation or some such.
All suggestions gratefully accepted,
ANSWER: Perhaps you reassembled it incorrectly? There are gasket surfaces at the
ends of the filter that need to seal reasonably well, to the vacuum and to
the blank-off plate that gets screwed on with the wingnut at the bottom
The poor old vacuum cleaner is hard pushed to even suck through all the
filters you are using, and small leaks at the sealing surfaces are under
extra strain. The filters may even be collapsing under load.
As you have allergies, and the dust is causing you problems, I would suggest
you invest in a vacuum system that sends the waste air and crap outside your
house (or flat). This could be a purpose built system, or simply a couple of extra hoses so
you can keep the vacuum cleaner outside. I use my homebuilt system like this
in my workshop cleanups, and the fresh air is wonderful.
