iRobot Roomba n185240 maintenance set

The iRobot Roomba n185240 is the Roomba Plus 505 Combo sold in Europe in white – the colour differs from the black n185040, but the robot, the heated dock and every consumable are identical. It runs around 7,500 Pa with DualClean spinning pads and PerfectEdge extending reach, SmartScrub, ClearView Pro LiDAR with a PrecisionVision AI camera, and an AutoWash dock that heat-dries the pads after each wash.

This set covers the full service scope with Plus.Parts® direct-fit alternatives to the original iRobot parts 4837322 / 4849900 / 4849901 / 4849902 / 4849962: two Multi-Surface Rubber main brushes, four Edge-Sweeping side brushes, six high-efficiency filters, six AutoWash dock dustbags and six DualClean mop pads – 24 parts in all. On the 505 the dock and its drying chamber are where small neglect compounds. The heated dry keeps pads firm and low-odour, but the heater-dryer vent at the back collects lint that throttles airflow; a pad that returns damp on a heat-drying model is an airflow problem solved by wiping the vent monthly, not a worn pad. Empty the dirty-water tank after every mopping run and rinse the wash tray weekly, since old water in the tray spreads odour and grit back onto the pads, and only ever use iRobot-approved solution in the clean-water tank – other fluids foam in the micro-pump and damage its diaphragm.

Tap the high-efficiency filter every one to two weeks, keep it dry, and replace at four months at this suction tier. Clear the Multi-Surface Rubber main brush and both end caps weekly and replace it every six to twelve months; replace the Edge-Sweeping side brush every three to six months. Swap the PerfectEdge pads left-to-right at each wash to equalise wear and inspect at the eight-week mark. Wipe the PrecisionVision camera lens weekly, wipe the bin port and dock collar monthly for the 75-day bag seal, and clean the charging contacts monthly. Behind the set is a real team at VacuumReviews.eu, so if pads return damp or the dock develops an odour, reach out and we will help you work through the vent, tray and tanks.
