Key Takeaways
- Deepest cut of the week: The iRobot Roomba 800/900 high-efficiency filter 3-pack at 75% off, sitting at bestseller rank #59 in its category.
- Underrated find: The iRobot Dual Mode Virtual Wall Barrier is rarely on sale this deep, sold by Amazon at 70% off.
- roborock parts cluster: Multiple Dyad Pro and Flexi accessories sit at a flat 70% off, useful if you bought a wet/dry stick last year.
- Bundle vs parts math: The Roomba 104 vacuum + edge-sweeping brush bundle only makes sense if you need the vacuum too. Don’t buy it for the brushes.
- Prices verified May 3, 2026.
This is the first warm weekend where I pulled my Roomba out from under the couch and realized the side brush had basically transformed into a felted hairball. The filter looked like it had survived a small fire. If you’re staring at a bin full of dust and a brush that looks more like a tumbleweed, you are not alone, and apparently neither are the algorithms, because replacement parts are everywhere this week.
This Berry Basket leans hard into Roomba replacement parts because that’s where the markdowns landed. iRobot dropped authentic 800/900 series filters and rubber brushes deep, and even the Dual Mode Virtual Wall Barrier is sitting at a price I haven’t seen since last year’s holiday window. roborock is running a parallel sale on Dyad Pro and Flexi accessories, which is unusual since those wet/dry sticks are still relatively new in the lineup. The pattern says spring cleaning to me, but it also tracks with Mother’s Day being a week and a half away. A pack of fresh filters is a strange gift, but a working robot vacuum is not.
Heavy on robot vacuum maintenance gear this week, with two kitchen replacements at the end for anyone whose Brita pitcher tastes like the inside of a fridge.
What are the best Roomba replacement parts deals?
The strongest Roomba parts deals this week are on iRobot’s authentic 800 and 900 series consumables, plus the Virtual Wall accessory. Discounts run from about 44% up to 75%, which is the deepest cut I’ve tracked on iRobot filters in 90 days.
iRobot Roomba 800/900 Filters
iRobot Roomba Authentic Replacement Parts – Roomba 800 and 900 Series High-Efficiency Filters (3-Pack)
This is the deal I’d grab without thinking if you own a Roomba 800 or 900 series. It’s a 3-pack of authentic high-efficiency filters, which means you’re set for roughly a year and a half if you swap every two months like iRobot recommends. Bestseller rank #59 in its category tells you these move constantly, so the 75% cut is genuine, not an inflated original price.
- 3-pack of authentic high-efficiency filters
- Fits Roomba 800 and 900 series
- Bestseller rank #59 in category
iRobot Virtual Wall Barrier
The Dual Mode Virtual Wall Barrier is one of those accessories you forget exists until your Roomba keeps wandering into the dog’s water bowl. It works with the 600, 700, 800, and 900 series, and you can set it as a halo around an object or as a straight-line barrier across a doorway. Sold by Amazon at this price, which I’d take over a third-party seller every time.
- Dual mode: halo and barrier
- Compatible with 600, 700, 800, 900 series
- Sold by Amazon
iRobot Roomba Rubber Brushes
iRobot Authentic Replacement Parts- Roomba 800 & 900 Series Multi-Surface Rubber Brushes (1 Set of Multi-Surface Rubber Brushes)
Pair these multi-surface rubber brushes with the filter pack above and you’ve basically reset your 800 or 900 series Roomba. Rubber brushes hold up better than the older bristle versions if you have pets, because hair doesn’t wrap around them the same way. One set, not a bulk pack, so check what came with your unit before you buy.
- Multi-surface rubber brush set
- Fits Roomba 800 and 900 series
- Better for pet hair than bristle versions
iRobot Roomba Plus Replenishment Kit
iRobot® Roomba® Authentic Replacement Parts – Replenishment Kit for Roomba® Plus 400 & 500 Combo Robot + AutoWash™ Dock
For owners of the newer Roomba Plus 400 and 500 Combo robots with the AutoWash dock, this replenishment kit covers the consumables in one box. It’s a useful sanity-saver if you’ve been ordering filters, brushes, and pads piecemeal. At 49% off it’s not the steepest discount on the page, but bundled kits rarely go deeper than this.
- Covers Roomba Plus 400 and 500 Combo
- Includes filters, brushes, pads
- Compatible with AutoWash dock
iRobot Roomba 105 Replenishment Kit
iRobot® Roomba® Authentic Replacement Parts – Replenishment Kit for Roomba® 105 Combo & Vac Robots
Same idea as the kit above but sized for the Roomba 105 Combo and Vac robots. If you bought a 105 in the last six months, this is the cheaper way to handle the first round of swap-outs. Just verify your model number before you check out, because the 104 and 105 kits aren’t cross-compatible.
- Sized for Roomba 105 Combo and Vac
- Authentic iRobot parts
- Sold by Amazon
Which Roomba bundles are worth it?
One Roomba 104 bundle made the cut this week because the math works out in your favor only if you actually need a new robot vacuum. As an excuse to buy parts, it falls apart.
iRobot Roomba 104 Vacuum Bundle
Bundle of iRobot Roomba 104 Robot Vacuum & Mop + iRobot® Authentic Replacement Parts Edge-Sweeping Brush 3-Pack
This is the Roomba 104 vacuum and mop with a 3-pack of authentic edge-sweeping brushes thrown in. The 53% discount is real, and the savings hit $250 because the bundle includes the robot itself. If you’ve been waiting on an entry-level Roomba upgrade with mopping built in, this is a clean way to do it. If you only want the brushes, walk away.
- Roomba 104 robot vacuum and mop
- Includes 3-pack edge-sweeping brushes
- Sold by Amazon
Which roborock replacements should you grab?
roborock has a flat 70% off across most of its Dyad Pro and Flexi accessory line right now, plus a 50% cut on the universal microfiber mop cloths that fit nearly every Q-series and S-series robot. If you own a roborock, this is the week to stock up.
roborock Flexi Lite Roller Brush
roborock Soft Roller Brush for Flexi Lite Cordless Wet Dry Vacuum Cleaner, Mop Vacuum Replacement Parts Accessory Kit
Roller brushes on cordless wet/dry vacuums get gross fast because they’re constantly damp. This soft roller fits the Flexi Lite, and the kit includes the parts you’d actually want to keep on hand. 70% off is the same price I saw during a flash sale last fall, so this is roborock’s true floor for this part.
- Soft roller for Flexi Lite cordless wet/dry
- Replacement accessory kit
- Trusted brand
roborock Dyad Pro Washable Filter
The washable filter for the Dyad Pro, Dyad Pro Combo, and Dyad Air. Washable doesn’t mean immortal, and roborock recommends swapping every few months even if you rinse regularly. At this price it’s worth keeping a backup in the cupboard so you don’t have to wait three days for shipping when the current one finally gives up.
- Fits Dyad Pro, Dyad Pro Combo, Dyad Air
- Washable and reusable
- Recommended swap every few months
roborock Microfiber Mop Cloths
This 2-pack of microfiber mop cloths fits a long list of roborock robots, including the Q5, Q7, Q8 Max, S5, S6, and S6 MaxV. Bestseller rank #58 in mop accessories, which is a good sign that they wash and reuse well. Half off, which is the most common discount roborock runs on these.
- 2-pack microfiber pads
- Fits Q5, Q7, Q8 Max, S5, S6 series
- Bestseller rank #58 in mop accessories
Are eufy robot vacuum parts worth the price?
eufy’s pure replacement parts are harder to find as standalone listings, so most of this week’s eufy deals are vacuum-plus-parts bundles. The C10 side brush 6-pack is the exception, and it’s the one I’d actually recommend.
eufy C10 Side Brushes
eufy C10 Ultra-Slim Robot Vacuum (2.85") Replacement Side Brushes (6 Pieces) Compatible Self-Empty C10
Side brushes are the part that wears out first on most robot vacuums because they take the brunt of edge cleaning. Six brushes for the ultra-slim C10 self-empty model is enough for a couple of years of normal use. Note that this listing is bundled with the C10 vacuum itself based on the price, so confirm exactly what’s in the box before you commit.
- 6-piece side brush replacement
- Compatible with C10 ultra-slim self-empty
- Bundled with C10 vacuum
What kitchen replacements deserve attention?
Two kitchen replacements rounded out the week, both from brands worth trusting on consumables. Brita’s pitcher filters and a De’Longhi steam nozzle for espresso machines.
Brita Pitcher Filter 6-Pack
Six Brita pitcher filters at 52% off works out to roughly a year of replacements if you swap every two months. Bestseller rank #183 across all home and kitchen, which is wild for a consumable that’s been on the market this long. If your tap water has been tasting flat lately, the filter is almost always the reason.
- Six standard pitcher filters
- Roughly 40 gallons per filter
- Bestseller rank #183 home and kitchen
DeLonghi Steam Nozzle
The De’Longhi steam nozzle (part 5313231221) fits a long list of their espresso machines, and if yours is sputtering or leaking around the wand, this is usually the fix. It’s a small part at a small price, but having one in the drawer is the difference between a five-minute repair and a week of pour-over coffee. Worth grabbing if you own any De’Longhi espresso machine.
- Replacement part 5313231221
- Fits multiple De'Longhi espresso machines
- Common fix for sputtering steam wands
Frequently asked questions
Do iRobot replacement parts work on all Roomba models?
No. iRobot’s authentic parts are model-specific, so a filter made for the 800/900 series won’t fit a 600 series or a newer Roomba 105 or j-series. Always check your robot’s model number on the underside of the unit before ordering, and look for “compatible with” language on the listing.
How often should I replace Roomba filters and brushes?
iRobot recommends swapping filters every two months, side brushes every three to six months, and the main brush roll every six to twelve months depending on use. If you have pets or run the vacuum daily, lean toward the shorter end of that range. Worn parts make the motor work harder and shorten the life of the robot.
Are aftermarket Roomba parts worth buying instead of authentic ones?
Sometimes, but not when authentic iRobot parts are this discounted. Aftermarket filters often have looser tolerances and can leak dust back into the air, which defeats the purpose. At 75% off, the genuine 800/900 filter pack costs less per filter than most third-party options, so there’s no reason to compromise.
How long do Brita pitcher filters last?
Brita’s standard pitcher filters are rated for about 40 gallons or roughly two months of typical household use. The included sticker indicator on most pitchers helps you track it. Hard water and heavy daily use can shorten that, so a 6-pack usually covers a year for a single household.
Will the roborock Dyad Pro filter fit other roborock vacuums?
This particular washable filter is designed for the Dyad Pro, Dyad Pro Combo, and Dyad Air cordless wet/dry vacuums only. It will not fit the Q-series or S-series robot vacuums. roborock’s robot vacuums use a different filter shape, so check the model name on your unit before ordering.
The discount range across this week’s home and kitchen replacement parts ran from 36% on the lighter kitchen items up to 75% on the iRobot 800/900 filter 3-pack. Most of the iRobot consumables sat in the 44% to 70% band, and the roborock accessories were almost uniformly at 70% off, which suggests a category-wide promotion rather than scattered markdowns. Bundle pricing on the Roomba 104 vacuum hit 53% off with a real $250 dollar savings, which is one of the larger absolute discounts I’ve seen on an entry-level robot this spring.
The standout for me is the iRobot 800/900 high-efficiency filter 3-pack. Bestseller rank #59, sold at the lowest price I’ve tracked on this exact part, and it’s a consumable you will absolutely use. The Dual Mode Virtual Wall Barrier is the second pick because it’s sold by Amazon at 70% off and that almost never happens. What I’d skip is the larger eufy bundles. They’re priced as full vacuum purchases with parts attached, and if you don’t need a new robot, the per-part value evaporates. Browse all deals if you want to see what else is moving this week beyond the parts category.
Looking ahead, I expect more replacement parts to follow as we get closer to Memorial Day and the early-summer cleaning push. iRobot tends to run a second wave of consumables sales right before Father’s Day, so if you missed the 75% filter deal, another window is likely in mid-June. roborock’s flat 70% across the Dyad line feels like inventory clearing, which usually means a new model is around the corner. If you’ve been on the fence about a Dyad Pro itself, that may be worth waiting another month on.
