My 880 was having difficulty finding home and thoroughly cleaning a specific room so I took the opportunity to perform a factory reset, setup everything again, and placed it in a better location. It's the room I want vaccumed the most.
It doesn't clean the whole house.
It is stuck in a loop. Like pinball.
It can't work its way out when it is stuck.
Can't always find homebase and eventually dies.
I just bought it last December. The company doesn't care. I might sell it and get a nice cheap robot vaccum cleaner from Walmart. The one I had before wasting money on this piece of sh** Roomba was reliable.
