I have been researching bots for a while.. I even got in on the S9+ and m6 deal a week or two ago on amazon but it was disappointing to say the least.. Supposedly this is the new latest and greatest thought the software supposedly isn't as good as roborock. Anyways the bot itself was going from amazon for 100$ off 650$ but it was from a seller with only 5 sell history so I didn't trust that. I saw this deal today with an auto emptying base. The base is usually 250$ on ecovac's website and the bot is 650$. Even if they don't charge you tax this best buy deal still comes out better with tax by over 100$(for me at least). It is usually $900 on their website and even with the $100 off coupon that that seller had on amazon this is still a better deal. The T8 is supposed to be better than the AIVI for it's better avoidance skills than even the camera that the AIVI has.
Anyways please go easy on me if I made any mistakes.. This is my first post..
