It works perfectly and suction is strong. Very easy to Setup, registration (use gmail). Wi-fi connection must be 2.4 ghz .The best thing I like is it can block off area you do not want the vacuum cleaner to enter the room or underneath computer table which have lots of cables can causes entangled to the vacuum rollers. It can save up to 10 maps, so you can select which map you want to clean. It also has both side brushes for better cleaning. Some other brand do not has this function. The manual and voices are in Chinese version but phone app is English language. Must upgrade firmware for better performance. Highly recommended.Jan 08, 2019
