Pros - Very efficient, convenient to use. Mops/cleans very well, no more pressing the mop for cleanser job. Cons - very short battery power, charged fully and mopped my second floor, and the kitchen then the battery power ran out. My house is not huge total 1,800 sq .ft. It's not fun to wait one-two hour and resume the job as most prefers to get over with when the cleaning starts. But overall, very happy that I bought this.
