I actually LOVE this AI. I wish I didnt waste all the time hesitating to buy it. We dont have time to clean as often as we should and we have 4 pets so the need is definitely there. The Roomba is turned on (from wherever we are) once to twice a week and I get to come home to a clean house. Its wonderful. Because the house was quite dirty upon first use the rollers showed wear after only 24 hours but customer service was easy and pleasant to deal with and replaced it immediately with no issues whatsoever. No issues since. Customer service is also Australian... massive bonus. I wanted to give a star less because the vacuum bags are ridiculously expensive and not environmentally friendly AT ALL but I just couldn’t. Too happy with the product. Hopefully Roomba would one day realise that they’re a bit greedy with that aspect and make re-usable vacuum bags.
