Gardiner Backpack v3 Review for Water Fed Pole Window Cleaning

In this review I give my own experience and opinion on the Gardiner v3 backpack after using it for 3 years to clean windows. We talk about the design of the unit, the battery life and I also talk about how it differs from some of the other backpacks I've had in the past, including a Shurflo backpack and a cheap trolley style one I bought off ebay.
