After waiting 7 months for backorder, I tested this vacuum for 3 weeks before returning it. With all that waiting, I guess my expectations were too great and it could not exceed it. I'm comparing my experiences with the Roomba S9+, Deebot T8+ AIVI, Deebot N8 Pro+, and Shark AI. They all had their plus/minuses. Overall, in terms of cost + usability + performance + reliability, I ended up with the N8 Pro. Wished the JetBot AI+ performed better, it really looks hecka cool.
