Let me start by saying I love the i9 when it worked properly. Better than my samsung or irobot. The i9 started giving me problems and customer service sent a shipping label to return it and they would replace it with a new unit.
It was received by the warehouse received the unit over 10 days ago. I've gotten silence and finally thank for your patience.
I love the i9 but wont buy another one. Totally frustrating.
