Bests & Worsts Reviews from Amazon

We purchased this 6 months ago and up until 2 weeks ago, I would’ve given it a 5 star review. We had plans of purchasing a more expensive model from a different brand and decided to purchase this to see if we’d actually use a robot vacuum. Turns out, we loved it and decided not to purchase the other brand because this worked perfectly and did exactly what we needed it to do!! Our floors are primarily hardwood and tile. We don’t keep shoes, toys, clothes, etc laying around. To be honest, I never thought I’d be dependent on a robot vacuum...until it doesn’t work properly! Two weeks ago, it started acting funny. I read the reviews to see if anyone else had this problem but didn’t have any luck. I contacted the manufacturer and still haven’t received a response. The battery is fine. It turns on and only cleans about a 2ft space. It goes 2ft, stops, turns, goes 2ft, stops, turns, and keeps doing this. It has a 1 yr warranty but the manufacturer won’t respond. I’ve cleaned the brushes like others have said to do. Any other ideas??
