This is the most asked question and many people always confuse this question so let me tell you the answer. There are so many robot vacuums in the market and all are good in their place but more choice means more confusions that's why I have only listed 4 best robot vacuums for high pile carpet and I know these all are medium-high pile carpet but there is no robot vacuum for high pile carpet in the market that's why I have shared these medium pile carpet robot vacuum cleaners. All are best in brand and reviews that's why it is very easy to choose any of them.
