I have had this since May 2015, and it is still working great. I use it a couple times a week to mop almost my whole house. It starts out by going in an outward spiral and then back into the centre again in order to get the water flowing correctly. It then goes around the edges of the room. After that, it's pretty random. But it still gets every single spot. It goes over everything a couple times and really gets it nice and clean. Then finally it goes over everything once again and squeegees it, getting it pretty dry. It shakes itself off to get rid of any drops of water and then cleans up after itself before notifying you it's finished.
Generally I fill it with hot water and a little bit of Pinesol. It took roughly 45 minutes to clean my kitchen in this video. It's a pretty fantastic little machine and I'd highly recommend it. The water I emptied out this time wasn't even half as dirty as it usually is... I had just used it a day or two ago before making this video. With my kids the floors can get pretty nasty, but this thing cleans it with ease and saves me from mopping 1000sqft of linoleum! It is a little loud, but it gets the job done and that's all I care about. It's a must have in any busy mothers life.
