iRobot Roomba Combo – Plus.Parts® Maintenance Set

The iRobot Roomba Combo is an entry-level vacuum-and-mop hybrid whose defining feature is a mechanical fold-up cleaning pad that lifts out of the way when the sensors detect carpet, so rugs stay dry during a combined run. That design also sets its maintenance rhythm: the pad carries dry dust and wet soiling at the same time, so iRobot specifies replacing it every 50 washes – about seven weeks of daily mopping – because the fibre compresses and starts dragging old soil back across the floor long before it looks worn. The onboard water tank is user-filled, so emptying it and leaving the port open to air-dry after each session matters, because standing water grows a biofilm that transfers odour to the floor. Meanwhile the rubber main brush packs a dense ring of hair at its end-cap bearings and the two-stage filter loads steadily as the robot works.

This maintenance set keeps every one of those intervals stocked with Plus.Parts® components built as a direct-fit alternative to the original iRobot part: a rubber main brush, four edge-sweeping brushes, four high-performance filters and two cleaning pads, each sized to the Roomba Combo’s own mounts so fitting them is no different from swapping the originals. The filter earns its place first, because the Roomba Combo’s high-performance element must never be rinsed – water destroys the electrostatic charge it relies on, making it a replace-not-wash part; a fresh element keeps fine dust trapped and suction steady, while a clogged or wetted one quietly lets dust drift back into the room.

The cleaning pads hold their absorbent texture instead of stiffening and smearing early, and the rubber main brush uses a hard-wearing compound that stays supple across its six-to-twelve-month life.
