Most of us probably buy online from IRobot or other dealers like Amazon
There are some stores in the US that are not nationwide. What one person has in their area may not be in others.
Be careful of Linens and Things as they are now bankrupt but still in business.
Others would be:
Bed Bath and Beyond
Big Lots (& other closeout stores for the 4xxx models)
Hammacher Schlemer (hard to find these retail - mostly online)
Costco but you have to pay 5% above cost or have a membership if you want to return after short period. Their extended warranty is just for members.
Not in Seattle but elsewhere:
Filene?s Famous Barr - NY, RI, VT, CT and ME
Robinson May CA, NV, AZ
Foley?s -TX, NM, OK, LA, and OK
Hechts PA, NJ, MD, VA, NC, and TN
Hammacher Schlemmer NY and IL
According to IRobot, this is the complete list so if you register your item with them you will be on shaky ground if you did not purchase it from one of the places on the list. I have seen others mentioned that have now started carrying them and they are warranteed.
Be sure to familiarize yourself with the cleaning and maintenance procedures on these if you will not have a deal locally in Norway to assist.
