Quick Answer

If you want a vacuum-only robot from iRobot, the Roomba Max 715 Vac ($699.99 list) is the closest replacement for the discontinued Roomba j9+: a self-emptying dock and a much simpler ownership experience than a mop robot. For the strongest carpet cleaning on paper, the Roborock Saros 20 ($1,599.99 list) is rated for 36,000 Pa and reviewers rate its cleaning highly. The Shark Matrix Plus 2-in-1 remains our mid-range pick, and the Dreame X60 Max Ultra Complete is the premium alternative to the Roborock.

November 2026 update: the Roomba j9+, Roborock S8 MaxV Ultra and Dreame X40 Ultra from our previous version have all been replaced by newer models. The new picks below have not been tested by us; specs come from the manufacturers and the notes from named reviews.

What makes carpet cleaning hard for robot vacuums?

Carpet is the most demanding surface for any vacuum — robot or otherwise. Debris gets embedded deep in the pile, especially in medium and high-pile carpets. Pet hair weaves into fibers and resists suction. And traditional bristle brush rolls tangle with long carpet fibers and hair, eventually losing effectiveness or requiring frequent manual de-tangling.

Three things separate great carpet robot vacuums from mediocre ones:

Note on pile height: Most robot vacuums handle low-pile carpet (under 10mm) and medium-pile (10–20mm) well. High-pile/shag carpet (over 20mm) is challenging for any robot vacuum and may require manual vacuuming or a robot specifically rated for high-pile use.

Best Vacuum-Only for Carpet: iRobot Roomba Max 715 Vac ($699.99 list)

iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock

iRobot's 2026 vacuum-only flagship: a three-stage cleaning system, a self-emptying dock with bags iRobot rates for up to about three months, and no mop hardware to maintain. The closest current replacement for the Roomba j9+.

Check Price on Amazon

The Roomba j9+ is discontinued. iRobot replaced almost its whole range in 2025, went through Chapter 11 in December 2025, was bought by its former manufacturer Picea, and launched a new North American lineup in July 2026. The Max 715 Vac is the vacuum-only model at the top of that range, listed at $699.99 (PCWorld has seen it on sale at $499.99).

Key specs

If you liked the j9+ because it kept things simple — no water tanks, no mop pads — the Max 715 Vac is the model to look at. Be aware of what reviewers found, though: PCWorld reports that it navigated around furniture and larger obstacles without trouble but struggled with smaller objects, and that its dock is as loud as much larger self-emptying stations. That makes it less of a stand-out than the j9+ was in its day.

Best Premium (with Mopping): Roborock Saros 20 ($1,599.99 list)

Roborock Saros 20 Robot Vacuum and Mop

Roborock's 2026 flagship: rated for 36,000 Pa suction, an AdaptiLift chassis that lifts itself over thresholds, StarSight navigation, Matter support, and a dock that empties, washes and dries the mops.

Check Price on Amazon

The S8 MaxV Ultra was Roborock's flagship until the Saros line took over in 2025 (Roborock never made an S9). The Saros 20 reached the US in late March 2026 at $1,599.99 and is the model we would point carpet-heavy, mixed-floor homes to now.

Key specs

Reviews are strong on cleaning and lukewarm only on price: Android Authority calls it "a superb cleaning machine", Expert Reviews calls it expensive but excellent, and HGTV says it may be worth it if you want an all-in-one system that needs very little hands-on upkeep. A pet-owner review noted it occasionally left stray dog hair on top of the robot. Discounts have been common since launch, so check the current price.

Best Mid-Range for Carpet: Shark Matrix Plus 2-in-1 (~$400)

Shark Matrix Plus 2-in-1 Robot Vacuum & Mop

Matrix Clean navigation with 4x4 cleaning grid, sonic mopping, home mapping with no-mop zones, and a bagless self-empty base. The best carpet performance under $500.

Check Price on Amazon

The Shark Matrix Plus 2-in-1 offers legitimate carpet performance at a fraction of flagship prices. Its Matrix Clean navigation — a methodical grid pattern that covers the floor in overlapping passes — is particularly effective on carpet where multiple passes extract more embedded dirt than a single systematic sweep.

Key specs

The Matrix Clean's overlapping grid pattern is a genuine advantage on carpet. Instead of one systematic row pass, it makes cross-directional passes over the same area, which is physically more effective at lifting embedded debris from carpet pile — mimicking the technique a skilled human vacuumer would use. For homes with a mix of carpet and hard floors, the Shark Matrix Plus handles both surfaces well at a price that's hard to argue with.

Premium Alternative: Dreame X60 Max Ultra Complete ($1,699.99 MSRP)

Dreame X60 Max Ultra Complete Robot Vacuum and Mop

Dreame's 2026 flagship: rated for 35,000 Pa suction, a 3.13-inch-thin body, ProLeap step climbing, and a fully self-cleaning dock.

Check Price on Amazon

The X40 Ultra has been replaced twice: first by the X50 Ultra (February 2025), then by the X60 Max Ultra Complete, which went on sale in the US on February 10, 2026 at $1,699.99 — the same launch price as the X50 Ultra Complete. Dreame's own store has since discounted it.

Key specs

Reviewers like how it cleans but are split on value. Android Authority found it great at cleaning floors, but noted that it runs through water quickly and that the mop pads tend to pop off. Gizmodo called it too pricey, while saying it vacuums and mops well once the settings are right. For carpet-first homes, the Roborock Saros 20 is the safer premium pick; the X60 is worth a look if you have thick rugs, steps between rooms, or low furniture.

How to choose a robot vacuum for carpet

Use this decision framework to match your needs to the right model:

Our Verdict

Best Premium for Carpet: Roborock Saros 20 ($1,599.99 list) — the highest rated suction here, anti-tangle brushes, a self-lifting chassis and a full-service dock, with strong reviews from Android Authority and Expert Reviews. The pick for large homes with carpet and hard floors if the budget allows.

Best Vacuum-Only: Roomba Max 715 Vac ($699.99 list) — the closest replacement for the j9+ for people who don't want mopping. Reviews are more mixed than the j9+'s were, so look for it on sale.

Best Mid-Range: Shark Matrix Plus (~$400) — The overlapping Matrix Clean pattern is a genuine differentiator on carpet, delivering more thorough debris extraction than single-pass systematic cleaners at a fraction of flagship prices.

Premium Alternative: Dreame X60 Max Ultra Complete ($1,699.99 MSRP) — a slimmer body and step-climbing hardware; choose it for thick rugs, steps between rooms or low furniture.

Frequently Asked Questions

How much suction (Pa) do I need for carpet cleaning?

For low-pile carpet, a few thousand Pa is sufficient. Medium- and high-pile carpet benefits from more, which is why 2026 flagships like the Roborock Saros 20 (rated 36,000 Pa) and Dreame X60 Max Ultra Complete (35,000 Pa) quote such high figures. Brands measure Pa differently, so brush design and carpet boost matter as much as the headline number.

Are rubber brush rolls better than bristle rolls for carpet?

Rubber and anti-tangle brush rolls are dramatically better for pet hair on carpet — they don't tangle as easily, they maintain consistent performance over time, and they require far less maintenance. For homes without pets, high-quality bristle rolls (like the Shark Matrix Plus) are also effective. With pets, go anti-tangle.

Can robot vacuums handle thick shag carpet?

Most robot vacuums struggle with shag or high-pile carpet over 20mm deep. Robots that can lift their chassis, like the Roborock Saros 20 (AdaptiLift) and Dreame X60 Max Ultra Complete (ProLeap), have better odds of getting onto thick rugs, but even these are not ideal for very deep shag. Check the manufacturer's maximum pile height spec before purchasing for shag carpet homes.

Will a robot vacuum with mopping wet my carpet?

All three mop-capable models in this roundup (Roborock Saros 20, Shark Matrix Plus, Dreame X60 Max Ultra Complete) automatically lift or retract the mop pad when they detect carpet. This prevents wetting carpet during a cleaning cycle. However, always verify this feature is active and working on your specific setup before running unsupervised.

How often should I run a robot vacuum on carpet?

For homes with pets or heavy foot traffic on carpet, daily runs are recommended. Without pets, 3–4 times per week keeps carpet looking clean. The higher frequency also prevents debris from working deeper into carpet pile over time, making each cleaning session more effective.

What replaced the iRobot Roomba j9+?

iRobot did not name a one-to-one successor. Its closest current vacuum-only model is the Roomba Max 715 Vac (July 2026, $699.99 list), and the Max 775 Combo ($999.99) adds a roller mop and a mop-washing dock. If you find a j9+ on clearance or refurbished, it is still a capable carpet robot, but check that replacement bags and brushes are available.

What is carpet boost and why does it matter?

Carpet boost is a feature where the robot automatically increases suction power when it detects carpet, then reduces it on hard floors. This maximizes cleaning performance where it's needed (carpet) while preserving battery life on hard floors — extending total cleaning coverage per charge compared to running at maximum suction throughout.
