I very carefully put the mop together, being sure to read the instructions. I heard all the clicks, everything seemed intact, but unfortunately the solution leaked out after I completed my mopping. A couple hours later I noticed a large puddle on the floor. I inspected the mop again, and everything seemed to be in place, but the solution continued to leak. Which sucks bc I wasted all that cleaner. Besides that I like the concept, I like the mop itself. Easy to handle, the pad is nice and thick. There's some weight to the mop, which makes me feel like it's really rubbing the surfaces and removing dirt well.
