I purchased this product at the beginning of the year and have had consistent issues with it from the get go. We had purchased a Rhoomba for my mother as she no longer is able to effectively clean. The Rhooma has been fantastic. I decided to go with the Samsung version as my whole home is Google/Samsung equipped. The 7040 has issues performing the most basic of tasks. It constantly gets jammed up going from hardwood to carpet. It gets "stuck" under items that it should have detected low clearance. It dies mid cleaning. It does not perform scheduled cleaning well over 50% of the time. It does not automatically charge the few times that it returns to port. This has been a complete waste of money. It does not even make an effective paper weight, because it has a mind of its own half the time.
