Found this to be the cheapest price. Xiaomi robot vacuum 1st gen at $340 and 2nd gen at $509 at https://www.kogan.com/au/buy/xiaomi-roborock-s50-robot-vacuu…
I know it has been cheaper before but with dollar rate, cant find any cheaper prices than this.
if you request a deal from gearbite, you'll get this for cheaper + you get proper warranty
