I have more proteam backpacks then I can count, they all have turbo brushes and hard floor vacuum heads, rarely use the easy
glide head
I don't own an upright anymore
sometimes it not always about what you remove but what you don't put back, if you have a good vacuuming schedule then backpack are not an issue, they do take a little getting use to
I have several commercial accounts that will tell you they have less issues since backpack vacuuming are being used in thier facilities, not sure how you can even do a through detailed job in an efficient manner with an upright in a commercial setting
have sold quite a few to customers, once they get use to th evacuum they don't go back to uprights
proteam now sells an electric head version but it is rather expensive
