Hi, I'm currently using the trolley system for cleaning windows but I'm not a massive fan and I'm thinking of changing to a tank system. I only have a small van so was gonna go for the Facelift Compact, and definitely the one with the power up he reel. Would it be worth spending over £1000 to upgrade? Guessing il be saving quite a bit of time each day, especially with the power up reel. thanks Adam
