I was disppointed in the first function as a sweeper. I did not come away impressed that pushing the dust mop across the entire floor would actually pickup the dirt. IT was too time consuming to do what a wide dust mop would do in 10% of the time. The mopping has been a pleasent surprise. I like the 3 mop heads that allow me to slip off the dirty, top off the mop solution of small amount of vinegar with warm water and turn it loose again. I was impressed with the unit's abilty to keep track of where it had been and the battery life of 3 mopping sessions before battery recharge. This allow our family to mop more with cleaner floors, hassle free.
