Well being a IQ Robot advocate I received the new 1000AE. 
What a disapointment. 
I sent the first one back because of the noise level. It sounded like two pieces of plastic are hitting each other. After another 3 days of waiting on the replacement. So afterall that poor company action,  It is also LOUD!  As well I tried the new unit, it does take a longtime to map your home out. After 5 times it does not have it. After reading many comments to delete current map and start over, so I will try that. I am considerating returning 1000AE SHARK IQ Robot and get my money back. I am going to give it One more try.
I have another IQ Shark Robot 850 series which was doing the job even with the sepentine action and hitting the walls and furniture hard.
