This is the Shark IQ 2-in-1 model and my 1st robovac. I've always liked Shark products but was skeptical about whether this type of vacuum would work. The set up was really easy and once I set it up it did it's 1st sweep of the apartment. I was surprised that it zipped along without issue and didn't get stuck. We had vacuumed the day before so I assumed there would be little to empty out of the dust container. Wrong....I was amazed how much crud it still picked up. The mop function cleaned our tiny kitchen floor with ease. The app control works well and is easy to use. Another great Shark product!
