iRobot Roomba i5158 – Plus.Parts® Spare Parts Set

The iRobot Roomba i5158 is a numeric variant of the Roomba i5, iRobot’s smart-mapping mid-range model. The i5 added home mapping to the i series: the robot builds a layout of the space over its first few runs and stores it, making room-specific and zone-specific cleaning possible through the iRobot Home app. Optical floor tracking guides navigation across rooms, and twin rubber extractors handle both carpet and hard floors in a single pass. The extractors are the primary consumable: they contact the floor on every run, accumulate debris, and gradually harden as the rubber compound ages. The high-efficiency filter traps fine particulate across multiple sessions before it needs replacing, and the side brush sweeps edges and corners until its bristles flatten. Addressing all three categories together at replacement time resets the robot to its out-of-box performance in a single service step.

This spare parts set contains Plus.Parts® components designed as a direct-fit alternative to the original iRobot consumables: dual rubber brushes, 3 side brushes, 3 filters and a cleaning tool. Nine parts matched to the i5158 mounting geometry and service intervals. The rubber brush compound stays flexible through the full replacement cycle, and the filter media uses a dense weave that maintains capture efficiency as loading increases across the interval.

The set is built around the maintenance schedule the i5158 operates on. Whether the question is about fitment for a specific regional variant or anything else, our team answers personally and works to sort it out quickly.
