18 Pack Replacement Parts Accessories Compatible for iRobot
✅ PROS
- 18 pieces total — enough for a full year of maintenance on one Roomba
- Third-party price is roughly 60% less than OEM equivalents from iRobot
- Filters and brushes fit i3, i3+, i4, i7, i7+, i8, j7, j7+, and j8 models without modification
❌ CONS
- Roller brushes are hollow-core style — slightly less rigid than genuine iRobot rollers
- No replacement dustbin filter gasket included; the OEM rubber seal fits, but you'll need to transfer it
The Verdict
The $19.49 Question: Can Third-Party Roomba Parts Actually Keep Up?
If you own a Roomba i3 or i7 series, you already know the dirty secret: genuine iRobot filters and brushes cost a small fortune. A single OEM filter runs $15–$18. This kit gives you 18 pieces for $19.49. That math is the entire reason this product has 225 ratings and a 4.5-star average. But cheap only matters if it works.
Here’s the real story.
What’s Actually in the Box
You get six high-efficiency filters, six side brushes (three-prong style), two sets of rubber roller brushes (so four rollers total), and four extra side brush screws. As shown in the product image, the packaging is straightforward — no fancy retail box, just a sealed bag with everything inside. For a full year of weekly cleaning on one robot, this is genuinely enough consumables.
The filters are the pleated type with a foam border, matching the OEM dimensions exactly. The side brushes have the correct angled bristles and the same center-screw mounting pattern. The rollers are the two-piece rubber style — the black and red combo that iRobot uses on the i7 and newer models.
Real-World Performance: Where It Holds Up, Where It Doesn’t
I ran these through a month of daily use on an i7+ with pets. The filters capture fine dust well — no visible dust escaping the bin, and the filter frame seals properly against the dustbin housing. The side brushes snap in without wobble and survive normal wear against baseboards and furniture legs.
The rollers are where you’ll notice the difference. Genuine iRobot rollers have a solid, dense rubber core. These feel slightly hollow and more flexible. In practice, that means slightly less aggressive pickup on thick carpet — you might see a few more hair strands left behind on high-pile rugs. On hard floors and low-pile carpet, the difference is negligible.
One thing to flag: the kit doesn’t include the small rubber gasket that sits between the dustbin and filter. You’ll need to transfer the one from your old filter. It’s a 30-second job, but worth knowing before you throw everything away.
What Buyers Consistently Praise
The overwhelming theme in the reviews is cost savings without a major quality drop. One verified buyer put it plainly: “I was skeptical, but these work just as well as the iRobot brand ones I was paying triple for.” Another noted, “Fit my j7+ perfectly — no adapters, no trimming, just drop-in.” Multiple reviewers mention the side brushes lasting beyond the expected 3-month replacement cycle.
Where It Falls Short
- Roller rigidity: As noted, the hollow-core rollers are less aggressive on thick carpet. If you have wall-to-wall shag, stick with OEM.
- No gaskets included: That missing rubber seal is a minor annoyance, not a dealbreaker.
- No return of the 4 extra screws: You get exactly four spares, and two of mine were slightly burred on the threads. A file or a different screw from the original set fixed it, but it’s sloppy QC.
Who Should Buy This
Buy it if you have an i3, i7, or j7-series Roomba, you’re okay with 90% of OEM performance at 40% of the price, and you don’t have high-pile carpet throughout your home.
Skip it if you’re a carpet-obsessive with thick pile everywhere, you want the absolute longest lifespan per filter, or you’re uncomfortable transferring the gasket from old filters.
FAQ: Three Questions Shoppers Actually Ask
Q: Will these fit my Roomba i3+?
Yes. The kit is explicitly compatible with i3, i3+, i4, i7, i7+, i8, j7, j7+, and j8 models. The rollers and filters are the same size across those lines. No cutting or modification needed.
Q: How long does one filter last?
With weekly use and a pet in the house, expect 2–3 months per filter. That’s comparable to OEM — the foam border holds up, and the pleats don’t collapse early. You’ll use all six in roughly 12–18 months.
Q: Are these genuine iRobot parts?
No. They’re third-party compatible replacements. They fit and function like OEM parts, but they’re not made by iRobot. If warranty coverage is a concern, swapping in these parts won’t void your Roomba’s warranty — consumables aren’t covered anyway.
The Verdict: Buy It If You’re Tired of OEM Pricing
Rating: 4.6/5 — This kit isn’t perfect, but it delivers exactly what it promises: functional, compatible replacement parts at a fraction of the OEM cost. The roller softness is a real tradeoff, but for $19.49, you’re saving roughly $50–$60 compared to buying the same pieces from iRobot.
Buy it if you want year-round maintenance without the brand-name tax.
Skip it if you demand OEM-equivalent rigidity on thick carpet or you’d rather pay double for the peace of mind of genuine parts.
Either way, you now know exactly what you’re getting — no surprises when the box arrives.
