Doesn't clean dog hair over the carpets, specially on thin carpets. Rather it spreads dogs hair all over instead of sucking inside. One to clean the carpets again with a regular vacuum cleaner. Stops every now and then for no reason. Can't send it home or restart cleaning the same room from where it stopped once the default time limit to restart expires. Misses several spots Noisy once fan speed is increased. However, at lower speed it does not clean well. So, one has to increase the speed. Does not perform as advertised. Just too expensive for the quality it delivers.
