Mini Shop Vac

I find I use my mini shop vac quite a bit around metalworking. Not big chips obviously but just sucking up swarf off the machine or work & general house/shop duties. Suction wise its pretty good, but the canister & size doesn't really lend itself to metal like it did with woodworking & general clean up. I am cheap so I empty the bag several times & re-install.

I got looking at these kind of more upright cans & from what I can tell, no bag at all. Just the motor intake filter inside.

They always show them sucking up messy, fine particulate like fireplace ash or BBQ pits. Are these new technology or still like older gen shop vacs I've had where yes, 80% of fine stuff like drywall dust stays in the pail but 20% bypasses & gets pumped out the exhaust & re-distributed over everything you own? Being bag-less, the metal chips might not have this issue but would it impale the filter & then I'm buying new ones of those all the time? Any recs or comments welcome. I don't really want to build a cyclone although I see the logic in them.
 
I bought the biggest rigid shop vac home depot sold because they said it was the quietest model. I buy generic bags from amazon and they do ok. supplies from HD for it are stupid expensive. I can't empty the bag as it just busts. I usually pick up most swarf with a homemade magnet pickup sweeper.

While a lot of my equipment may suck, my vacuum is one piece of equipment that does and I'm glad!
I use a wet/dry Craftsman shop vac. It's big and cumbersome but has an air cleaner style filter and the canister is the bag....although I think you can get disposable bags for it. I use a fine filter bag (made for drywall dust) between the disposable air filter and the canister itself. I just about never replace the inner filter and only occasionally shake off/hose off the fine "filter" cloth bag, that catches it all. It has good suction and big hoses/inlets. I suck up all sorts of oily swarf with it all the time. Occasionally I will get a jam when sucking up big long swarf. It's also very loud.
 
Ended up getting this one

Suction & noise seem good. I find the big diameter hose a bit clunky. Of course they sell a smaller more flexible one as an add-on. I wonder how that paper filter will hold up to metal swarf. I know with wood dust & regular duty crap I would just brush along the creases & clean it off. But the swarf may impale the paper. Guess I'll find out.

That’s similar to the one I bought. I did get the car kit with the long hose. I use it frequently and appreciate it not as loud as some of the vacuums out there. My neighbor has a real screamer a few doors down. I can hear it inside my house when he’s running it in his garage.

Knockoff bags on amazon are ok. I clean the filter with compressed air. I haven’t had to replace it so far. I ran it without bags but it just blows so much more dirt out the back the bags help with that.

That essentially is similar to my craftsman. If a cloth bag is not available you may want to make your self one. On my vacuum when I use the extra cloth bag I attach the suction hose down on the drain outlet. The extra cloth bag does cut down on suction force but it really doesn't matter much as I still seem to be able to suck up shop rags, notes, 22 shells, loose new carbide inserts and the like.

the last bit here sounds horrible
 
The open canister sounds like the ticket. Lost an allen key to my ShopVac today LOL. When I opened the vac up to see If I could recover the key I discovered the bag was full to the nuts and weighed in at 6 lbs. Was way over due for a bag change but still sucking up all manner of stuff.

Some run time on my Home Depot Ridgid shop vac. I quite like it. Much quieter than my older generation. Wasn't too badly priced. Metal swarf just drops to the bottom where its supposed to. I think the deflector nozzle inside helps with that. No bag just using the canister and the basic filter that came with it. Not much swarf in the filter. That's one of the things I was concerned about - sharp heavy swarf piercing the paper fan element & bung it up quickly. I don't use a ton of cutting oil but for sure the chips are a bit oily. Again no issues with the filter. The hose is a bit big diameter but its light & not stiff. It will suck a shop rag off the table :/

I use my shop vac in a similar manner but I suck up all sorts of oily swarf and messes. I don't have any problems with the filter but the hose and canister does get a build up of oily dirt residue. I think a vacuum is the best way to pick up swarf as the brooms get the stuff all tangled up and makes a mess of the broom.IMG_20190429_0659072.jpgIMG_20190429_0658111.jpg

John I just saw you post now. I'd never heard of anyone using bags with shop vacs—I at least never did. This seems like a good idea though. I have the older 6.5HP Stainless Rigid Contractor Vac, which I don't think they sell anymore. Using the Husky 3 mil contractor bags seems like a great idea. Do you just cut a hole for the outflow?
 
Garbage bags do seem like a good idea but I use closed generic vacuum bags as they keep the filter
cleaner. Filters are really expensive.

Valid point.

Do you clean your filters John? I don't think I've bought more than one in 15 years. I blow them out with compressed air and they work like new. I know some people use a gentle hose as well.

Correction to earlier post...my big vac is a ShopVac, but my smaller one is a Rigid. I clean the filters in both though.
 
When I empty my canister I take off the filter & give it a light brushing in between the corrugations. Just have to watch out for impaled chips because the paper will tear rather easily. This particular shop vac model seems to stay a bit cleaner than my prior one, so either the swirl dynamics are better or I'm vacuuming more metal shavings & they are heavier & so dropping out faster. When I vacuuming fine wood dust it tended to coat the filter much more rapidly & you could hear the motor working. Then I used one of those permeable pre-filter bags like shown in post-12. That helped keep the filter cartridge from plugging off fast. I think if you are doing drywall dust or similar fine particles, that would be a must. And cleaning those is a PITA. I walked around the yard & gave it an occasional snap, then a big cloud of dust. Keep moving so you don't breath it in.

Probably alternating wood & slightly oily metal swarf is a perfect recipe for mung buildup. My nozzle & hose looked like the picture ^^, but seemed to be confined to the first foot or so. I don't know what to say there - clean it out every so often. Maybe just water & detergent & let it soak for a bit? Worst case scenario replacement hoses didn't look too expensive but they change vacuum models faster than you wear them out.
