iRobot Roomba Y311240 – Plus.Parts® Replacement Parts Set

The iRobot Roomba Y311240 is the Roomba 105 Combo + AutoEmpty Dock sold in Europe under an alternate retail code — same robot, same consumables, different product label. It delivers up to 7,000 Pa suction through a multi-surface rubber roller, pairs it with a flat microfibre mop on hard floor, navigates with a chassis-integrated ClearView LiDAR at 10.1 cm for access under low furniture, and empties its 0.4 L bin into an AutoEmpty dock bag iRobot rates at 75 days, with six to eight weeks being the realistic replacement window under everyday use. The Carpet Detect sensor signals a suction boost automatically when carpet is detected. The dock does not run an auto-wash cycle for the mop pads, so a brief hand-rinse after each mopping session is the sole care step required between replacements.

This set keeps the Y311240 stocked with Plus.Parts® consumables built as a direct-fit alternative to the original iRobot part: one multi-surface rubber roller, three side brushes, five high-efficiency HEPA filters and three flat mop pads — twelve parts in all. Clear wrapped hair from the rubber roller and clean both end-cap bearing holes weekly; the holes are a common place for fine grit to lodge and add drag, so use a fine-tip toothpick to keep them clear, and replace the roller every six to twelve months. The high-efficiency filter should never be rinsed with water, as the pleated medium permanently loses its structure when wet; tap it firmly on both sides every one to two weeks and replace it every four to six months, or as soon as the medium turns a consistent mid-grey, since at 7,000 Pa the pickup drop at that point is immediate and pronounced rather than a slow decline.

Inspect the side brush hub weekly and clear any thread accumulated at its base; replace the brush every three to six months when the tip ends curl and no longer direct debris toward the robot rather than flicking it along the wall. Supplied by Plus.Parts® as a direct-fit alternative to the original parts.
