First let me say that this is NOT A WET/DRY VAC. I want to emphasize that because that was a question I had since I first found out about this, but never saw anyone mention it. I contacted Milwaukee directly, and they responded to my e-mail very quickly .Great service.
Quick Review:
Great Vac This is a DRY VAC ONLY, Very quiet and powerful. Great runtime with the 9 and 12.0 ah batteries
I love the design(You try to battle my boys, that's not legal OWWWWW)
Cons: The placement of the power switch makes it a hassle to power on and off especially if you are hanging it from a ladder. When attached to other tools the vac pulls its (due to suction) while you are pushing the tool. You may have to buy the 9ft hose to fix that
More In Depth Review
This BackPackVac is surprisingly quiet. , all of the noise that you will hear is basically from the attachment nozzles. If you take them off(the crevice tool and wand) It is virtually quiet. I think the pivot point for the hose is a great idea, adds lots of mobility to the tool. I barely had to put this on high. Having it on Low I will able to pick up everything that I need to, dust bunnies, dirt, saw dust. I put it on high on carpeted areas to get the stuff that the carpet was attached to and it worked. On Low I measured about 67db and high was around 74db for me
This lost a star from me due to placement of the power switch. This is advertised as a 3 in 1, so you can wear it, carry it and hang it. To me it is a burden to operate it while it is hanging. I found that since the power switch is located on the bottom of the vac, trying to turn it on and off while hanging it from a ladder can be rather cumbersome. I had to keep going up and down the ladder to hit the switch.
One suggestion for an updated model would be to have to two places to turn the vac on from, one of which could on top of the Vac. Looking at the new heated gear from Milwaukee, they can take a page from their book and have the emblem on the strap turn it off and on by pressing it. Making it a lot easy to switch modes and not have to worry about your shoulder.
I used this with several tools and it did not perform that well. I attached it to my cordless router, myM18 circular saw and m18 Jigsaw and I still had lots of dust flying around. I think it was mainly due to the placement of the vacuum ports on these products, it is on the back of the tools. I feel they would have more effective on the front, at the point of the cut capturing the dust soon as it forms. The hose has a nice rubbery connector that fits snugly around the ports which is good.
While attached to these tools, the hose contracts when in use, at times making it hard to maneuver the tool, the vac is pulling it while you are pushing it. I see why they have an optional 9ft hose, I will try it with that and that should make it more manageable.
Some other suggestions I have are: Again taking after the M12 products , have an onboard fuel gauge making it easier to see how much juice you have left in your battery. There is a packout dolly, I think it would be good to have an attachment so you can hook this up to a dolly and roll the Vac around like a tradition shopvac so you do not have to carry it. Also add a light somewhere. It's 2018 it seems like everything has an LED light so when you get something without it , you really notice the missing feature. Having a led would be great, especially when I am on my sites for New Construction and cleaning up after all the sheathing is on and there is no natural light coming in . This way I can touch up without breaking out an additional light source.
Pros: Easy to Clean, Easy to Install, Easy to Use, High Quality, Looks Great, Nice Design, Sturdy
Cons: vac pulls the attached tools as you operate it, the placement of the power switch
