iRobot Roomba Plus 504 Vac – Plus.Parts® Maintenance Set

The iRobot Roomba Plus 504 Vac sits one tier below the Max 705 at 150 times the Roomba 600 suction reference, but everything that wears is shared: the same Dual Rubber anti-tangle brush compound, the same Edge-Sweeping brush, the same HEPA-rated filter, the same 0.7-micron AutoEmpty dock and bag, and the same ClearView Pro LiDAR navigation. iRobot specifies one replenishment kit for both the Max 705 and the Plus 504 precisely because the parts are identical, which is why this set fits the 504 exactly as it fits the flagship.

The set supplies Plus.Parts® consumables built as a direct-fit alternative to the original iRobot part: two Dual Rubber main brushes, three Edge-Sweeping side brushes, three high-efficiency filters and three sealed AutoEmpty dock bags, eleven parts in total. The slightly lower 150x airflow is the one place the schedule shifts – it extends filter life toward the four-month mark rather than the three-month end of the window, so a 504 run weekly without pets can sit at the longer end, while daily or pet use pulls it back in line with the 705. Tap the filter firmly every one to two weeks, keep it dry, and let the white-to-mid-grey colour shift, not the calendar alone, make the call.

Clear both rubber-brush end caps and axle hubs with a toothpick every two weeks and replace the pair every six months; the lower suction tier does not change brush wear, because hair binds the hubs mechanically regardless of airflow. Inspect the three-pronged Edge-Sweeping brush weekly and replace it every two to three months, and replace the dock bag every four to eight weeks, wiping the auto-empty port seal each time so the dock keeps transferring debris cleanly. Give the ClearView Pro LiDAR window and PrecisionVision lens a weekly dry wipe to keep mapping stable, and clean the charging contacts monthly. Behind the set is a real team at VacuumReviews.eu, so if the 504 feels weaker on low-pile carpet than it should, reach out and we will help you check whether it is the filter, the brushes or the bin throat.
