Andrew,
Your thoughtful discussion and sharing of personal experience is greatly appreciated!
In lieu of Richard’s comment, I would be concerned that unfamiliarity or incompatible ergonomics would discourage use of the backpack vacuum cleaner and the biggest problem the DMS has is getting people to spend 5-10 minutes cleaning up individual messes, not cleaning the entire space for hours at a time. Also, as far as commercial/industrial use, we already have inexpensive shop vacs for that kind of thing. Extension cords can easily make up for a 25’ foot cord limitation and are endlessly useful for other applications.
Mind, I’m not poopooing any particular brand,
Well, it is not just a matter of brand, but individual models from the same manufacturer can vary greatly in performance and satisfaction as you alluded to. I value actual personal experience and data over hype and perception and in some cases I have found inexpensive equipment to perform surprisingly well or even better than more expensive and allegedly better manufactured units.
When I worked commission radio repair for several years, a lot of the techs used Makitas. But I found them heavy, unwieldy and annoying to use (hated the awkward reverse switch) and happily made over $55 K a year just using my cheap Black & Decker drills that only cost a fraction as much.
Perhaps another consideration is the warranty period; I could definitely see a value in getting something that is warranted for 3 years such as the ProTeam you recommend versus something else that might be only 90 days.
Thank you for the site link with the breakdowns - it is very interesting.
