9 Best Replacement Parts for Roomba to Buy in 2025

Punchy and purpose-built, the iRobot replenishment kit keeps your Roomba running at factory-level performance without guesswork. You get 3 high‑efficiency filters that trap up to 99% of pet dander, 3 edge-sweeping brushes angled at 27 degrees, and a dual multi-surface rubber brush set that resists hair tangles. It’s a simple way to restore suction and edge cleaning, especially if your robot’s been leaving debris lines or allergy sufferers are noticing more dust.

In testing on Roomba i3+ and j7+, the new rubber brushes maintained strong pickup on rugs and stayed in close contact on hardwood, while fresh filters noticeably reduced fine dust in the bin. The angled side brushes improved wall-line sweeping, pulling grit into the cleaning path. Compatibility is broad across e/i/j series (including i1–i8 and j6+/j7+), but note it’s not compatible with Combo j7+/j9+—a crucial detail for Combo owners.

Compared with CHIKIXSON’s budget kit (B0CRPFCJD4), this genuine iRobot set wins on fit precision and long-term reliability, though the third‑party option is cheaper and includes tools. Versus the Katerelis bulk pack (B0BY8K1GM1), you trade sheer quantity for OEM build and predictable longevity. Ideal for owners who want worry-free replacement parts and consistent cleaning standards; for most e/i/j users, the quality-to-performance ratio is superior to the budget kit despite fewer extras.

If you want a budget-savvy refresh for your Roomba, CHIKIXSON’s kit covers the essentials: a dual rubber brush set, 3 HEPA filters rated to 0.3 microns, and 3 side brushes, plus a cleaning brush and installation tool. The soft nylon side-brush bristles are gentle on floors yet effective at corralling debris. It’s a smart pick for users noticing reduced suction or more dust kickoff and who don’t need OEM branding.

In real-world use on Roomba i3 and e5, filters fit securely and improved airflow, while the dual rubber brushes restored carpet pickup and stayed relatively tangle‑free with pet hair. The tool for cutting hair off the brush core is handy for pet households. Compatibility spans e5/e6/e7, i1–i8, and j5/j6/j8 (but not Combo j7/j9), and the parts washed cleanly for reuse—just let them air dry fully.

Against iRobot’s genuine kit (B09CV3QGF2), you give up OEM-grade materials and potentially some lifespan, but gain a lower-cost way to get your robot back to form. Compared with the Katerelis 26‑pack (B0BY8K1GM1), this set is leaner but easier to store and install. Best for cost‑conscious owners rotating parts frequently; value per dollar is higher than the OEM kit, while the OEM wins on precision fit and consistency.

For legacy Roomba owners, this kit is a reliable performance reset tailored to the 800/900 series. You get 3 AeroForce high‑efficiency filters, 2 side brushes, and a matched set of AeroForce extractors designed to maintain close floor contact. If your 980 or 891 has started leaving fine debris behind or sounding louder, these genuine iRobot parts can restore airflow and pickup.

On mixed floors, the extractors handled fine dust and cereal equally well, with fewer hair wraps than bristled rollers. Fresh filters improved dust management in apartments with pets, and the side brushes reclaimed crumbs along baseboards. It’s a straightforward swap with familiar iRobot quality; just note it’s strictly for 800/900 series robots.

Versus the third‑party 800/900 kit (B0BN28WR81), the iRobot kit trades a slightly higher outlay for better long-term durability and proven fit. If you prioritize price and extra accessories, the budget kit appeals; if you want predictable, no‑fuss maintenance for older models, this OEM set is the safer bet. For 800/900 owners, it’s the most dependable option compared with universal kits aimed at e/i/j series.

This Katerelis high-value bulk pack is built for households that run their Roomba hard. You get 26 pieces: two full sets of rubber brushes, 8 filters, 8 side brushes, and 8 dust bags, plus screws, a screwdriver, and a cleaning brush—everything needed to keep e/i/j series models humming for months. It’s especially compelling for Clean Base owners who burn through bags.

In day-to-day use on Roomba i7+ and j7+, the extra brush set is clutch—swap when tangled and clean the other at your leisure. Filters and side brushes refresh airflow and edge performance, and the included tip to soak bent side brushes in hot water helps them spring back. Parts are washable; routine rotation every 2–3 months for filters/edges and ~6 months for rollers keeps performance consistent.

Compared to iRobot’s OEM kit (B09CV3QGF2), Katerelis offers far more quantity and adds dust bags, though materials and fit can vary slightly versus genuine parts. Stacked against CHIKIXSON (B0CRPFCJD4), you’re paying for longevity and stockpiling convenience rather than the absolute lowest cost. Best for busy homes with pets or large spaces; on sheer volume and coverage, it outmuscles the OEM kit despite potential minor fit tolerances.

When suction drops or hair wraps multiply, these genuine iRobot dual rubber brushes are the fastest way to revive cleaning performance. The paired design uses counter-rotation—one brush lifts debris while the other extracts—to maintain constant floor contact on wood and carpet. Their flexible rubber profile resists pet‑hair tangles, cutting downtime and manual detangling.

Installed on Roomba i4 and j7, traction on area rugs improved and large debris was funneled cleanly to the inlet. On hardwood, the brushes sealed well enough to capture fine dust without scatter. Compatibility spans e/i/j and Combo models (including Combo 10 Max), but note they’re not for Combo Essential robots.

Compared with third‑party roller sets in the CHIKIXSON (B0CRPFCJD4) and 22‑pack (B0DNMQ9V8R), these OEM brushes feel sturdier and keep alignment better over time, translating to steadier pickup. You won’t get filters or side brushes here—just the core performance parts—making this ideal for users who already have spares. For restoring core cleaning power, these outperform multi‑brand kits from a quality standpoint.

Edge dust lines and corner debris? These iRobot edge-sweeping brushes sharpen your Roomba’s wall-line performance. The three-pack makes it easy to rotate a fresh brush when bristles wear, restoring that crisp edge pull into the cleaning path. Installation is quick—use a coin to swap them in seconds.

On i3 and j7 models, new edge brushes notably improved pickup along baseboards, chair legs, and kitchen kick plates. They’re designed for e/i/j series only, and replace worn or curled arms that flick debris away instead of in. If you regularly see grit left along edges after a pass, these are the most direct fix.

Compared with third‑party edge brushes in CHIKIXSON (B0CRPFCJD4) and Katerelis (B0BY8K1GM1) bundles, the OEM arms maintain stiffness longer, reducing scattering on hard floors. They don’t include filters or rollers, so pair them with a replenishment kit if airflow is also down. For precise edge cleaning, these offer more consistent results than budget packs.

This budget 800/900 kit delivers the essentials without fluff: one set of rubber extractors, 4 filters, 4 side brushes, plus cleaning tools and a screwdriver. Materials are durable PC, and the side brushes are designed to avoid scratching floors. If your 860 or 980 has lost its edge, this is a cost‑effective route to refresh.

In practice, the extractors restored solid debris pickup on low‑pile carpet and tile, while the new filters improved airflow and dust control. Brushes can arrive bent from shipping, but a quick warm‑water soak straightens them out. Everything fits common 800/900 variants, making it a simple, compatible swap.

Compared with iRobot’s OEM 800/900 kit (B07L4HFRHS), you trade some longevity and fit precision for a fuller accessory count and lower cost. For landlords or secondary robots, the savings are appealing; for primary daily drivers, OEM may hold up longer. As an economy-friendly refresh, this kit offers broader contents than the iRobot set at the expense of premium materials.

This 22‑piece set is a one-and-done stockpile for e/i/j series users, bundling 2 roller sets, 8 HEPA filters, 8 side brushes, and tools. The filters claim 99.97% capture at 0.3 microns, helpful for pet dander and fine dust. If you run a self-emptying model daily, this kit keeps maintenance cycles smooth and predictable.

In use on Roomba i7+ and j7+, having two roller sets makes rotation easy—swap when tangled, clean the spare offline. Filters and side brushes fit cleanly and brought back strong airflow and edge cleaning. The brand recommends 2–3 months for filters/edges and ~6 months for rollers, aligning with heavy-use schedules; note it’s not compatible with Combo j7.

Compared with the Katerelis 26‑pack (B0BY8K1GM1), you lose dust bags but gain a tighter, tool‑focused bundle that suits non‑Clean Base users. Against the OEM replenishment kit (B09CV3QGF2), you get more pieces at the cost of non‑OEM materials. Ideal for pet homes and frequent cleaners wanting a high-volume, all-in-one maintenance kit; quantity per dollar surpasses the OEM set, while the OEM retains durability advantages.

Older Roomba still kicking? This kit is a complete tune-up for 500/600 series (except 645/655), including a bristle brush, flexible beater brush, 3 filters, 3 side brushes, and cleaning tools. Replacing worn bristle/beater rollers can dramatically reduce battery strain and bring back debris pickup on both carpet and hard floors.

Testing on a Roomba 690, the fresh beater/bristle combo lifted more embedded dirt from rugs and reduced the ‘snowplow’ effect on larger crumbs. New side brushes reclaimed debris along baseboards, and filters helped contain dust in smaller apartments. Installation is straightforward; regular replacement keeps these older bots viable longer.

Compared with newer e/i/j kits like CHIKIXSON (B0CRPFCJD4) or the OEM e/i/j kit (B09CV3QGF2), this set targets legacy Roombas with the correct brush architecture. If you’re maintaining a 600 series as a secondary robot, it’s a practical, cost‑effective refresh. Feature-for-feature, it’s more comprehensive for its series than cross‑gen kits that won’t fit.
