Yesterday was my 1st day using my new trolley. Gotta be much easier than using ladders I'm thinking - wrong!! There isn't much hose between hose connection and the pole valve, feel like I'm tethered to the damn thing . Constantly kept tripping over my own hose, the last time falling against a wall, resulting in 3stitches above my eye. Returned to job 2hrs later to find trolley showing DE message. Couldn't find fault so ended up tradding the job. Found out when I got home it needed to be re-calibrated. GRRRRRR! Today, just got started and the water froze in the hose in between windows. Getting pe'ed off a bit now. Continued tradding anyway, when I looked down from ladder, custys dog was cocking it's leg up against my trolley. Tell me it gets easier-Aarrghhhh
