"Trick or cheap robot vacuum cleaner"

I bought this robot vacuum in November’22 at Walmart.com in the US. Now it’s October ‘23 and the item is not working properly. The catch is that it is currently advertised at Walmart.com with “12 months warranty“, but it is BS, they provided a dummy email that doesn’t answer and also Walmart.com can’t do anything because due to the lapsed time it is on the manufacturer to fix it. So, avoid the cheap robot vacuum shenanigan.
