Wi-Fi doesn't work: I was finally able to figure out how to operate it via the remote control, so that's a plus, but I have most of the functions in four or bought useless, I should have opted for a cheaper model! Or more expensive, not sure at the moment if I bought it based on the reviews. I am very disappointed in this. Now, after 3 months of use, it doesn't hold a charge. I wish I had spent a little more considering it didn't even last 4 months. I was very disappointed because I did a lot of research but obviously you get what you pay for! Pay $100 more for a quality robot vacuum cleaner
