I was hesitant to purchase an industrial and scientific robotic cleaner, but after trying a few products, I stumbled upon this gem. Through trial and error, I found that this machine works well on various floor types and easily navigates around obstacles. The high suction power saved me a lot of time and effort. The only downside is that it requires a bit of maintenance, but it's worth the investment. Overall, I'm impressed with the results and would recommend this to others in the market for a reliable cleaning machine.
