iRobot Roomba i4550 – Plus.Parts® Maintenance Set

The iRobot Roomba i4550 is a numeric variant of the Roomba i4+, pairing iAdapt 2.0 optical navigation with Clean Base Automatic Dirt Disposal dock compatibility. The dock auto-empties the robot’s bin into a sealed AllergenLock bag after each run, reducing manual intervention between sessions. iAdapt 2.0 tracks floor movement optically and builds a progressive map of the cleaning area across sessions. The cleaning system is the shared Roomba mid-range platform: dual rubber extractors, a high-efficiency filter, and an edge-sweeping side brush. The rubber extractors harden with use and lose the flexibility that channels debris across floors and carpet. The filter fills with fine particulate gradually, restricting airflow the motor and dock both depend on. The side brush narrows its reach as its bristles flatten with repeated wall contact. All three need regular replacement to keep the system performing as designed.

This refresh kit contains Plus.Parts® components matched to the iRobot Roomba i4550: 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.
