I saw this and like the channel. My plan is to use a shop vac with cyclone for awhile, figured it would help someone here. I have noticed some of the new shop vac branded stuff is junk lately as well. https://youtu.be/hSN7PXwn1yU Bauer comes out pretty good

The producer certainly put a lot of work into it, and does a good job of comparing the units he tested in some real-world conditions for shop vacs (not dust collectors).

But comparisons are not tests. Test are documented (methods and results) to be repeatable by others, and their results can be compared against additional models tested later.

He does not compare by means easily and accurately repeatable for other models by other testers. Tests measure standardized specifications, such as: CFM of airflow, inches of H2O pressure/vacuum, etc.

He does not evaluate filtration. Are any of the units HEPA rated, or have HEPA filters available? Nor did he do anything to test even relatively how quickly different units’ filters would clog to a given measurable level (some % loss of max CFM).

Beyond this specific comparison, shop vacs really aren’t very good dust collectors, unless applied to the smallest dust producing machines. They simply do not suck enough volume to capture dust well from larger machines such as table saws, many planers, shapers/router tables, or large sanders. Their filters are relatively small and require cleaning or replacement too often, unless you use an effective separator with them (dust deputy, etc.). With effective tool attachments, they can work reasonably well with some portable power tools. They are generally designed to clean up the dust after it has already settled on surfaces, but not to pull it out of the air before you breath it, or it spreads and settles elsewhere.

+1 to AndyJ1s. This is a added rant. Many use the shop vac/cyclone combo with satisfied results. As mentioned above, there’s a difference between shop vacs and dust collectors. They both serve a good purpose. I have two shop vacs (6 and 20 gallon). I use them for the portable sanders, miter saw and vacuuming the floor. They do their job but noisy. My dust collector I use on all my tabletop machines, table saw, band saw, planer, edge sander and vacuuming is a HF 1 hp 13 gallon bag dust collector. I’m satisfied with it and it’s much quieter (sometimes I have to look to see if it’s on because how quiet it is). Been thinking about upgrading to a 2 hp 70 gallon collector with a higher cfm rating.

Most starting out in woodworking give a bad rap to small dust collectors over the shop vacs. They feel the suction at the end of the hose with the shop vac, then feel the suction at the end of the hose with a 660 cfm dust collector (if that’s what it will do) and think the shop vac is better for dust collection. But they’re not comparing the volume of air passing through. In addition you should still use a Air Filtration Unit at the same time in either case.

shop vac’s are fine for hooking up to miter saw but try using it on a table saw or planer,forget it.you need volume not suction for those machines.people always try and make a 80 dollar shop vac do what an 800 dollar dust collector does.good luck.
