I'm thinking of buying either the ProLux 10QT Backpack with bag, or the ProTeam SuperPac backpack vacuum. Do you have a preference. I saw a video review on the ProTeam one and it received a good review, but said the black hose was not as flexible as the ProLux, and the connector hose connector in the center was a turn to tighten connector and took more time to connect/reconnect. Btw...I liked your video very much, and the Sanitaire looks like a good choice too. My condo is 2,000 sqft with mostly shiny expensive porcelain floor and some carpet. Am I in danger of scratching the finish of the floors with either of the floor nozzles on ither of the backpacks I mention? Sorry with all the questions. Thank you
