iRobot Verro 500 Product Manual - Page 11

 How Verro Works Verro has a powerful motor that pumps 80 gallons of water per minute through the robot, generating suction at two vacuum intakes under the robot. The water passes through a filter bag that traps dirt and debris down to two microns in size. (For comparison, the period at the end of this sentence is more than 500 microns in size.) The force of the water being pumped up through the bottom of the robot and out through the top helps Verro maintain traction on the pool bottom and walls. Brushes at the front and back of the robot loosen particles attached to the walls and bottom of your pool so that they can be vacuumed up, along with all of the other loose dirt and debris. Verro's coverage algorithm allows Verro to brush and clean your pool all the way from the bottom to the waterline in only 60 - 90 minutes. www.irobot.com 11
