Not a good product
The Samsung Pay app currently has several in-app exclusive deals. The R9000 POWERbot is on sale for 399, and there is also a promo code for an additional $150 off. I'm not sure if the promo code is unique or not, but mine ends in -RJOZ for reference. This is the best price I've seen for this model. I have the entry-level Samsung POWERbot, and I personally find it far superior to Roomba.
