The iRobot Roomba Max 705 Combo is iRobot’s Max 700-generation vacuum-and-mop robot, building on the j-series foundation with refined AI-powered navigation and a fully integrated mopping system that operates concurrently with vacuuming. The combination handles light surface moisture in the same cleaning session as debris collection, making the robot practical across homes with mixed flooring. The AeroForce cleaning head drives the vacuum-side performance: two counter-rotating rubber rollers flex against hard floors and carpet pile, drawing debris into the suction path through continuous direct contact. That flexible contact is enabled by the rollers’ rubber compound, which degrades gradually with repeated use, stiffening until the brushes produce audible scraping instead of quiet rolling, the point at which a replacement pair restores the original pick-up performance.
This replacement set is matched to the Max 705 Combo’s AeroForce extraction head. It includes two Plus.Parts® rubber brushes in the correct counter-rotating configuration, using rubber compound formulated to hold its pliability from installation through the full replacement cycle. Installation follows the standard AeroForce sequence: open the brush module, remove the worn pair, seat the new rollers, and close.
The support team is available for any compatibility or order question.
