Shark Ninja RV2502AE Robotic Vacuum for 449.80
This seems to be newer model than RV1010AE and has more capacity.
I called shark ninja and the representative was able to give me another 10 percent off. Total: $401 without taxes with the coupon.
This includes 3 years VIP warranty.
The same model is $50 more in Amazon.
