Instructions were very clear on how to easily assemble the mop and how to use it. Must admit I had to get used to how the system works. Basically need to unlock the mop in order to spin it via the bucket.  I used the mop in an unconventional way and used it to clean my walls because some areas are hard to reach. To my surprise the mop cleans really well. Like that the clear and dirty water is kept seperate. Also, I like that the brush mechanism cleans the sponge during the spin cycle. A bit concerned about the wear and tear of the components and wondered about the life of the product and the cost of replacement parts, if available.  Time will tell. Good choice!
