Roomba Max 875 Combo vs Roborock Saros 20

The Roborock Saros 20 is the safer overall recommendation in this Roomba vs Roborock comparison today. It combines excellent independently tested hard-floor pickup, strong pet-hair performance, advanced threshold climbing, a highly automated dock, and a mature set of smart-home features. The Roomba Max 875 Combo is more interesting than previous Roomba flagships, however. At $1,199.99, it costs less at MSRP and introduces SealForce carpet technology, heated ThermaMist pretreatment, a self-cleaning roller mop, and iRobot’s most ambitious dock yet.

The problem is timing. The Max 875 was introduced only in September 2026, so many of iRobot’s biggest performance claims have not yet been validated by the kind of standardized independent testing already available for the Saros 20.

That means this comparison needs to separate specifications from proven performance. Roborock wins more categories today because we know how it actually performs. Roomba may eventually become the stronger choice for carpet-heavy homes or mopping, but those conclusions would be premature until the Max 875 receives comparable testing.

Roomba Max 875 vs Roborock Saros 20 at a Glance

Price and Value

Roomba has the clear MSRP advantage. iRobot currently lists the Max 875 Combo at $1,199.99, while the Saros 20 carries a $1,599.99 MSRP.

That $400 difference is significant, but robot-vacuum prices change frequently. Roborock has already offered the Saros 20 below MSRP through its U.S. store, so the real gap can be much smaller during promotions.

This is why live pricing matters more than comparing launch numbers alone. At $1,599.99 versus $1,199.99, Roomba has the stronger price argument. If Saros 20 falls close to the $1,300 range, its proven cleaning and automation make the value comparison much tighter.

Vacuuming and Suction: 35,000 Pa vs 36,000 Pa Does Not Decide This

Roborock advertises 36,000 Pa of suction, while iRobot advertises 35,000 Pa for the Max 875. That 1,000-Pa difference is not enough to declare a winner.

Suction pressure is only one part of robot-vacuum performance. Brush geometry, airflow, floor contact, navigation pattern, carpet sealing, debris size, and chassis behavior can all change how much material actually reaches the dustbin.

iRobot’s more interesting specification is its claimed 20 L/s airflow combined with SealForce. SealForce lowers a skirt around the chassis to create a tighter seal against carpet, concentrating the suction path rather than simply increasing the headline Pa number.

Roborock takes a different approach with its 36,000-Pa HyperForce system, DuoDivide brush, and adaptive chassis.

The major difference is evidence. Saros 20 has already completed independent cleaning tests. Vacuum Wars measured an 89% result in its embedded-sand carpet deep-clean test, while RTINGS found excellent hard-floor pickup and decent carpet performance.

Comparable Max 875 testing is not yet available.

Carpet Cleaning: Roomba Has the More Interesting New Idea

Carpet is the category where Max 875 could eventually change the Roomba vs Roborock balance.

SealForce is designed to lower a flexible skirt around the robot when it detects carpet, forming a tighter seal between the vacuum and carpet fibers. iRobot says this concentrates airflow and improves deep pickup rather than allowing suction to escape around the chassis.

The Max 875 also uses a hair-cutting main brush and anti-tangle side brush, which should help in homes where hair accumulates in carpet.

However, iRobot’s headline claim of substantially deeper carpet cleaning is based on its own comparison methodology. It is not a standardized head-to-head test against Saros 20.

Roborock, meanwhile, already has measurable results. Vacuum Wars recorded 89% embedded-sand removal from medium-pile carpet, above the category average in its testing. RTINGS describes Saros 20’s carpet performance as decent, noting that it handles larger debris better than fine particles embedded deeper in carpet.

Carpet verdict: Saros 20 is the proven choice today. Max 875 is the model to watch because SealForce could become a meaningful advantage if independent testing supports iRobot’s claims.

Hard-Floor Cleaning

Roborock has a clearer advantage on hard floors because independent testing is already available.

RTINGS found Saros 20 exceptional at picking up debris from hard flooring, leaving very little behind in typical passes. Its extending side brush also helps reach along edges and corners.

Max 875 combines suction with PerfectEdge, which extends both its roller-mopping coverage and side-brush reach toward walls and corners. That design is promising, but the vacuuming side still lacks standardized third-party pickup measurements.

Winner: Roborock Saros 20.

Mopping: Roller Mop vs Dual Spinning Pads

The two robots use fundamentally different mopping systems.

Roomba Max 875 Combo

iRobot uses a continuously self-cleaning PowerSpin Max roller mop. Before scrubbing, ultrasonic ThermaMist applies heated mist at up to 140°F to soften dried-on messes. The roller then scrubs the floor while applying 18 N of downward pressure according to iRobot’s current launch specification.

The roller extends toward edges through PerfectEdge, while the dock later washes it using 176°F water and dries it using 131°F heated air.

Conceptually, this is a strong design because fresh sections of the roller can continue contacting the floor rather than dragging the same dirty pad through an entire room.

Roborock Saros 20

Saros 20 uses two rotating mop pads. Roborock says the system applies up to 13 N of pressure on tougher stains, while an extendable mop improves edge coverage.

The dock washes those pads using water up to 212°F, dries them at 131°F, automatically dispenses detergent, and can trigger additional washing and mopping when heavy dirt is detected.

Independent testing gives Roborock an advantage in confidence. Vacuum Wars rates Saros 20’s mopping above average, while RTINGS describes stain removal as adequate for normal messes but not exceptional against difficult stains.

Keeping Carpets Dry While Mopping

Both companies have gone beyond simply lifting a damp mop a few millimeters above carpet.

Max 875 uses iRobot’s DriLift system. When carpet is detected, the roller lifts and a physical protective shield lowers around it to help keep wet surfaces isolated from carpet.

Roborock can take a more absolute approach: Saros 20 can leave its spinning mop modules at the dock when the cleaning task does not require them. It also adjusts chassis and brush positions for different floor types.

This makes Roborock particularly attractive for homes with expensive carpets or thick rugs where the simplest way to prevent moisture transfer is to remove the mops entirely.

Winner: Roborock Saros 20 for complete mop separation; Roomba deserves credit for an innovative integrated shield.

Pet Hair and Long Hair

Pet owners should be cautious about judging either product solely from anti-tangle marketing.

Roborock already has strong independent evidence. Vacuum Wars measured 88% pickup in its flattened pet-hair test and recorded no tangling in its 7-inch hair-tangle test.

RTINGS also found Saros 20 capable of removing most pet hair from carpet in a single pass.

Max 875 uses a hair-cutting main brush and anti-tangle side brush, and iRobot specifically markets the machine for homes with pets and long hair. Those features are promising, but there is not yet equivalent standardized third-party hair testing.

Winner today: Roborock Saros 20.

Obstacle Avoidance: Specifications Do Not Tell the Whole Story

Both manufacturers claim recognition of more than 300 common object types. Roomba combines PrecisionVision AI with ClearView Pro dual-line LiDAR, while Roborock uses StarSight Autonomous System 2.0 with 3D sensing and an RGB camera.

If we compared only product pages, this category might look like a tie. Independent testing says otherwise.

RTINGS found Saros 20’s obstacle avoidance inconsistent, especially on carpet. It also found that the robot does not reliably avoid pet waste. That is a meaningful limitation for homes with accident-prone pets because a robot vacuum should not be trusted to run unattended around a possible pet mess.

Max 875 is too new to have an equally mature obstacle-avoidance record.

That means Roborock cannot receive an unconditional win here simply because it is better tested. We know both its strengths and its failure modes; Roomba’s failure modes are not well established yet.

Thresholds, Rugs and Low Furniture

This is one of Roborock’s clearest hardware wins.

Saros 20 is only 3.14 inches tall and Roborock says it can navigate into spaces as low as roughly 3.13 inches under suitable conditions. Max 875 is 3.93 inches high, almost eight-tenths of an inch taller.

That difference can determine whether the robot reaches under a sofa, cabinet, or low bed at all.

Roborock’s AdaptiLift Chassis 3.0 also gives it unusually strong threshold capability. The manufacturer rates it for single thresholds up to 1.77 inches and a specialized two-stage threshold arrangement totaling up to 3.46 inches when the geometry meets Roborock’s specified conditions.

iRobot rates Max 875 for thresholds up to 3.5 cm, or about 1.38 inches.

Winner: Roborock Saros 20.

Dock Automation

Both docks handle far more than emptying a dustbin, but Saros 20 offers the broader automated maintenance system.

iRobot advertises up to 90 days of hands-free maintenance with Max 875, but that should not be interpreted as three months without touching the system. Water tanks still need attention, detergent gets consumed, filters and brushes wear, and the dock itself still needs periodic inspection and cleaning.

Winner: Roborock Saros 20.

Apps and Smart-Home Features

Roomba Home provides room mapping, schedules, targeted cleaning, zone control, and pet-area prioritization. Max 875 also supports voice-control integrations with major assistants. Launch coverage indicates Matter certification is still in progress rather than already complete.

Roborock’s app goes further in several areas. SmartPlan 3.0 can adjust cleaning strategy according to rooms and conditions, while the Saros 20 includes the built-in Hello Rocky voice assistant. The RGB camera also supports remote video interaction, and Roborock currently lists Matter compatibility along with Alexa, Google Home, and Siri-related integrations.

Winner: Roborock Saros 20 for current smart-home depth and established Matter support.

Maintenance and Recurring Costs

Neither robot is maintenance-free, regardless of how automated the dock appears.

Owners should expect recurring replacement or cleaning of:

• dust bags;
• filters;
• main and side brushes;
• mopping components;
• detergent;
• clean- and dirty-water tanks;
• sensors and wheels;
• wear components around the dock.

iRobot and Roborock both sell proprietary consumables and replacement parts, so recurring ownership cost should be considered alongside the purchase price.

Which Robot Is Better for Your Home?

Should You Wait for More Roomba Max 875 Tests?

If your main reason for buying Max 875 is its carpet performance, the answer is yes, waiting is reasonable.

A $1,200 robot vacuum is expensive enough that buyers should not have to rely only on manufacturer demonstrations. The most useful upcoming evidence will be standardized tests covering:

• embedded carpet debris;
• fine-particle pickup;
• pet hair;
• hair tangling;
• dried stain removal;
• pet-waste avoidance;
• navigation consistency;
• battery runtime;
• dock reliability over repeated cycles.

If those tests confirm the advantages iRobot is claiming for SealForce and its roller-mopping system, Max 875 could become one of the strongest premium robot-vacuum values. Until then, Saros 20 remains the easier product to recommend with confidence.

Roborock Saros 20 Pros and Cons

Frequently Asked Questions

Final Verdict: Roomba or Roborock?

Roborock Saros 20 wins this Roomba vs Roborock comparison today. It is not perfect—its pet-waste avoidance is a real weakness—but its hard-floor cleaning, pet-hair pickup, threshold handling, slim chassis, dock automation, and smart-home features are already supported by substantial independent evidence.

Roomba Max 875 Combo is the most interesting Roomba flagship in years. SealForce targets one of the hardest problems for robot vacuums, while heated ThermaMist and a continuously cleaned roller mop bring iRobot much closer to the most advanced competitors. Its $1,199.99 price also undercuts Saros 20’s MSRP by $400.

The issue is proof. A new technology should not win a comparison solely because the manufacturer says it improves cleaning by a certain multiple. If upcoming independent tests confirm iRobot’s carpet and mopping claims, the Max 875 could become the better purchase for carpet-heavy homes and one of the strongest values in the premium category.
