I need to buy my out of town grandparents a robot vacuum cleaner. They have no Internet at their place and, apart from setting up the machine, I won’t be able to help them use it. Can you guys recommend me something that my technologically challenged grandparents can use without an Internet connection? Also due to recent massive inflation and devalueation, my finances are quite limited. Xiaomi mi robot vacuum mop 2 pro is right around my budget but it needs an active Internet connection.
