So far I’m really loving my new shark robot. I had another brand robot vacuum that this is replacing and it’s been 100% an upgrade. This model is so much quieter which is important as I usually run this while I am working from home. Additionally, the mapping feature is so helpful. I love that it can recognize furniture and other items that are in its way and avoids them vs. knocking them over like my old one did. It’s obviously too soon to tell if the non-removable filter is an issue, but I’m very happy with this upgrade so far!
