iRobot Roomba Combo j7+ – Plus.Parts® Maintenance Set

The iRobot Roomba Combo j7+ uses the same robot chassis as the Combo j7 but docks to a Clean Base that auto-empties the onboard bin into a sealed disposable dustbag after each run. The robot-side maintenance schedule is unchanged from the j7 – the Clean Base adds the dustbag as a periodic service point and eliminates the manual bin-emptying task. All consumables are identical across every c-series and Combo j-series model, so all 18 parts in this set fit without modification.

This set covers the full service scope with Plus.Parts® direct-fit alternatives to the original iRobot parts 4812261 / 4812262: two sets of dual rubber brushes, four high-efficiency filters, four side brushes, four mop pads and two dustbags – 18 parts in all. The Clean Base transfer chute is the service point owners discover only when the auto-empty cycle stops completing. The extraction sequence pulls debris from the onboard bin through a narrow chute into the sealed dustbag using a burst of high-velocity airflow. Over dozens of cycles, fine compacted debris accumulates at the chute entrance where the robot seats against the dock, forming a partial blockage that reduces extraction efficiency before it becomes a full obstruction. The first symptom is a bin that stays partially full after a completed dock return – the auto-empty ran but did not fully evacuate the bin. The second is a chute-blocked error that interrupts the next cleaning run. Check the chute entrance monthly by lifting the robot off the dock and inspecting the contact point for any debris ring or compacted dust. A dry cloth wipe across the chute and robot exhaust port keeps the transfer path clear. An overfull dustbag creates back-pressure that compounds the restriction, so replace the bag proactively at forty-five days rather than waiting for the sixty-day prompt in heavy-use homes.

Tap the high-efficiency filter weekly and replace every two to three months. Clear both rubber brush end caps every two weeks. Replace brushes every eight to twelve months and side brushes every four to six months. Rinse the mop pad after every run, machine-wash weekly without fabric softener.
