The Shark AI Ultra 2 & 1 is absolutely the best self vacuum!! It was easy to set up and off it went! Love the app, I can set schedules when I want it to vacuum! The mop/sanitizer part of it, left my floors looking clean! I will say that the wet part takes a little bit to figure out putting together, but once you do it, it is easy. I love that I can come home to my floors all clean!! I like that it plays a little short song when it socks and disengages! I highly recommend and takes one less household chore off your list!!
