Assembled, fully extended and including the mop, the handle measures approx. 138 cm. mE the length is sufficient (I am 168cm tall). I have been using the product regularly for over 2 years and am very satisfied with it. The handle has a spring built in so that the mop can be winched out by pushing it in the trolley. This also allows the length to be adjusted.
When replacing the mop, be sure to detach the mop from the plate. I didn't have a spare mop to hand and therefore accidentally disposed of the whole head. Replacement plates were hard to find online.
