I just voted trolley because it was equal with the back pack and I don't think the backpack even warrants a mention in the poll.  Yes lots of people use them, but for me it is all about getting the work done in the shortest possible time, whether to make more money per hour, or to have more time off work.

Now before all the backpack users get on their high horse, I want to exclude the people who have a real system and use a backpack to clean not easily accessible areas, as they can be handy for that.  For people with a backpack as their only system, my advice would be get a real system, turn the water up, and work faster.  No you won't be using more water, you just won't be hanging around waiting on enough water to clean the glass.
