Bought July 20, issues statrted end of August, plastic window inside water tank came loose blocking machine to empty, Roborock sent another September 16, it broke in 2 days, water valve broke off causing machine to make mud, Roborock sent another next day it broke as well, between delivery time and communicating with Roborock took about 10 days each time, yesterday Oct. 26 water tank valve broke again. Roborock stated they would have to see if anymore were available. Tried to return to local Walmart Ponca City, they stated it's out of the 90 days, my calculation by 8 days. told me to conatct manufacturer.
I guess store pesonel cannot do anything as they get locked out because of time frame.
