Based on our own experience, the VIMANSA 3 pack brushes are perfect for our iRobot vacuum. The brushes are easy to install and fit seamlessly .They effectively pick up all debris and hair FROM our floors and carpets, leaving everything looking spotless. The price of the brushes is very reasonable, making this a great value purchase. Our only con is that they may wear out quicker than some other brands we have tried. Overall, we highly recommend these brushes for anyone looking for a reliable replacement option for their iRobot in their Home and Kitchen..
