It's always interesting for me to look at commercial products and different manufacturers' attempts to make things "worker proof" and easily repaired. Simpler designs seem to be better all around.
As frustrating as it is to have to repair the same failure-prone components over and over, it's really cool to have the ability to redesign, simplify, overbuild, and make a product or component as neatly bulletproof as it can be. Something that just "works"!
What struck me about this video is how many similarities the Mosquito has to the older Pro-Team design of 20+ years ago (which may still be used on certain models)...roto-molded body, twist cap with no latches, straight in hose entry, all-aluminum wand with no plastic coupler, wide slot floor tool...makes me think that Mosquito realized many of Pro-Team's design revisions are not really improvements at all, and a market exists for the older, simple, tried-and-true design with a few thoughtful tweaks.
Pro-Team was always the first name in backpack vacuum cleaners, and really created the market for them. But it seems like at this point they might be overdesigned and trading on the name.
