The iRobot RVA-Y1 is built on iRobot’s s9 platform, the D-shaped chassis with PerfectEdge Technology that positions the dual brush system directly at walls and baseboard edges. This is the configuration iRobot developed to address the cleaning gap round robots leave along straight surfaces: by placing the brush roll at the flat side of the D, the robot covers the strip that circular brushes skip. Behind the brushes, the s9 platform’s 40x Air Power suction handles embedded debris from carpet fibres and pet hair from surface irregularities that lighter suction leaves behind. The brushes are the mechanism the suction works through: when they wear, the intake loses the debris the suction should be pulling in, and effective cleaning drops below what the hardware is capable of.
This pair contains Plus.Parts® dual rubber brushes designed as a direct-fit alternative to the original iRobot brushes for the RVA-Y1. The brushes seat in the chassis slots the same way as the originals and use the same attachment points, so the swap requires no modification and no tools. The rubber stays flexible across the full replacement interval, a property that matters for a robot running daily, where brush hardening translates directly to reduced pickup.

In brief
- Direct-Fit Compatibility – Both brushes match the iRobot RVA-Y1’s s9 platform slots and attachment points for tool-free installation.
- Inspected Before Shipping – Every pair is checked before dispatch to confirm it meets the fit and finish standard the s9 brush system requires.
- Reliable Quality – Rubber compound selected for sustained flexibility through repeated daily use, not for cost at the expense of lifespan.
