The iRobot Roomba i8578 is a European channel variant of the Roomba i8+, pairing the top-tier i-series platform with a Clean Base automatic dirt disposal dock. The auto-empty system extends the go-between-empties window significantly: after each cleaning run, the robot docks and the Clean Base vacuums the collected debris from the dustbin into a sealed bag, enabling weeks of operation before manual intervention is needed. The floor cleaning works through the AeroForce dual rubber brush system: counter-rotating rollers flex against both smooth floors and carpet pile, drawing debris into the suction path from either direction. Imprint Smart Map enables room-level scheduling from the iRobot app, so the i8578 can run targeted passes or whole-floor schedules as the household routine requires. A robot configured for daily operation on this schedule puts consistent hours on the rubber compound, and the replacement cue is the gradual decline in pick-up performance that comes as the compound stiffens.
This replacement pair answers that maintenance need. It contains Plus.Parts® dual rubber brushes configured for the Roomba i8578’s AeroForce cleaning head, two direct-fit rollers in the counter-rotating format, sized to the original dimensions. The rubber compound holds its flexibility through the replacement interval, avoiding the gradual stiffening that leads to noise and reduced debris contact. Swap them in through the standard AeroForce process: release the brush module, remove the old pair, seat the new brushes, close.
