iRobot Roomba i3558 – Plus.Parts® Service Kit

The iRobot Roomba i3558 is a numeric variant of the Roomba i3+, with Clean Base Automatic Dirt Disposal dock compatibility. The dock collects debris from the robot’s bin into a sealed AllergenLock bag automatically after each run, reducing the manual steps between cleaning sessions. Navigation runs on iAdapt 2.0, optical floor tracking builds a progressive map of the cleaning area across repeated runs. The cleaning system is the shared Roomba platform: dual rubber extractors, a high-efficiency filter, and an edge-sweeping side brush. The rubber extractors stiffen with use and begin slipping past debris. The filter fills with fine dust progressively, restricting airflow the motor and dock both depend on. The side brush flattens and narrows its sweep radius. Replacing all three on schedule keeps the complete system, robot and dock together, performing as designed.

This maintenance pack contains Plus.Parts® components matched to the iRobot Roomba i3558: a set of main rubber brushes, three side brushes, three filters, and a cleaning tool, nine parts covering every scheduled replacement interval in one order. Each component fits the robot’s extractor bay and filter housing at the standard mounting points, with no modification needed. The filter media maintains denser flow characteristics than generic aftermarket alternatives, holding the airflow the motor and the Clean Base dock depend on through the full replacement cycle. The rubber brush compound holds flexibility through the service period, keeping the extractors effective rather than hardening before the interval is up.
