The Shark IQ Robot could not map our home after running it daily for 20 days. It repeatedly cleaned the same room even when it was in the recharge and resume mode. It did not make it into one room at all. Also several times, it could not find the base to recharge so it would run out of charge and stop. The Robot did vacuum the rooms it did enter very well. If the mapping worked better, I would have kept it instead of returning it.
