Verdict

The iRobot Roomba S9+ is a premium D-shaped robot vacuum featuring a 3-stage cleaning system with 30% wider dual multi-surface rubber brushes, vSLAM-based Imprint Smart Mapping navigation, and an automatic self-emptying Clean Base with a 1.7-liter allergen-trapping bag. Its main advantages include a powerful 2,200 Pa suction motor that automatically boosts on carpets, PerfectEdge technology for superior corner cleaning, and a 3,300 mAh battery delivering up to 120 minutes of runtime with recharge-and-resume functionality. However, it is quite loud during operation—especially when emptying into the base station—carries a premium price tag, lacks built-in mopping capabilities, and relies on ambient light for accurate camera navigation.

Max suction power

What it is: Maximum suction power is the highest pressure the vacuum motor is rated to produce, measured in pascals.

When it matters: Higher figures can help lift embedded debris from carpet, but brush design and airflow also determine real cleaning performance.

Importance: HIGH

N. of suction power levels

What it is: The number of suction levels shows how many power settings can be selected.

When it matters: More levels give finer control over noise, battery use and cleaning strength on different floors.

Importance: MEDIUM

Motor type

What it is: Motor type identifies whether the suction motor uses a brushed or brushless design.

When it matters: Brushless motors generally offer better efficiency and durability, although complete airflow design still determines performance.

Importance: LOW

Power

What it is: Power is the electrical input rating of the robot or its charging system.

When it matters: It describes energy demand, but it should not be treated as a direct measure of suction or floor-cleaning ability.

Importance: LOW

?

Cleaning modes

What it is: Cleaning modes are the distinct automatic or targeted cleaning programs available on the robot.

When it matters: A wider choice makes it easier to match cleaning behavior to rooms, spills, edges or quiet periods.

Importance: MEDIUM

Hide

Mopping capability

What it is: Mopping capability means the robot can wipe hard floors with a damp pad or active mop system.

When it matters: It is useful for fine dust and light marks, but it does not automatically mean the robot can replace deep manual mopping.

Importance: MEDIUM

Mopping system type

What it is: The mopping system type describes how the robot applies motion and pressure to its mop, such as a static pad, vibrating pad, rotating pads or roller.

When it matters: Active systems generally scrub dried marks better, while pad lifting and dock washing determine how practical they are on mixed floors.

Importance: HIGH

Mop pad type

What it is: Mop pad type describes the pad shape and attachment used by the mopping system.

When it matters: It affects floor contact, edge reach, replacement availability and whether the pads can be washed easily.

Importance: LOW

none

Mop pad material

What it is: Mop pad material is the fabric or fibre used to wipe and absorb dirt from the floor.

When it matters: It influences absorption, scrubbing action, durability and how easily the pad releases dirt when washed.

Importance: LOW

none

Mop pressure

What it is: Mop pressure is the downward force the mopping system applies to the floor.

When it matters: More controlled pressure can improve removal of dried marks, although pad motion and moisture delivery also matter.

Importance: LOW

Navigation

7.8

Show more

Hide

Primary navigation technology

What it is: The primary navigation technology is the main sensor system the robot uses to understand its position and plan a route.

When it matters: It affects route efficiency, coverage and how reliably the robot returns to its dock, especially in larger or more complex homes.

Importance: HIGH

Mapping capability

What it is: Mapping capability lets the robot create a floor plan instead of cleaning only from moment-to-moment sensor reactions.

When it matters: A saved map is important for room selection, no-go zones and predictable coverage.

Importance: MEDIUM

Real-time mapping

What it is: Real-time mapping updates the floor plan and the robot's route while a cleaning run is in progress.

When it matters: It helps you follow progress, spot missed areas and see where the robot is if it becomes stuck.

Importance: LOW

Multiple map storage

What it is: Multiple map storage keeps separate floor plans for more than one level or cleaning area.

When it matters: It is useful in multi-storey homes because the robot does not need to rebuild the map each time it changes floors.

Importance: LOW

Map editing

What it is: Map editing lets you divide, merge, name and adjust rooms in the app.

When it matters: Accurate room boundaries make room-by-room schedules and targeted cleaning easier to use.

When it matters: Shape influences corner reach and manoeuvring, although brush placement and route planning are equally important.

Importance: LOW

D-shaped

Height

What it is: Height is the vertical clearance required by the robot.

When it matters: A lower body can clean under more sofas, beds and cabinets, but measure the furniture gap before relying on it.

Importance: LOW

Width

What it is: Width is the side-to-side size of the robot.

When it matters: It determines whether the robot can pass between chair legs, furniture and other narrow spaces.

Importance: LOW

Length

What it is: Length is the front-to-back size of the robot.

When it matters: Together with width and shape, it affects turning space and access around closely placed furniture.

Importance: LOW

Weight

What it is: Weight is the mass of the robot itself, excluding its dock.

When it matters: A lighter robot is easier to carry between floors, while weight has little direct connection to cleaning quality.

Summary of the review

iRobot Roomba S9+ – can a 1300-euro robot vacuum really pay off?

The iRobot Roomba S9+ justifies its steep €1,300 price tag through a ground-up redesign that integrates extensive engineering improvements over predecessor models. Key advantages include a horseshoe-shaped chassis that enhances corner and edge cleaning, superior suction power, a scratch-resistant exterior, and a centrally positioned, easily removable dirt bin. The primary disadvantage is its exceptionally high cost, though the review concludes that consumers already inclined to spend €1,000 on a vacuum should invest the additional amount for the S9+.

iRobot Roomba s9+ Review: Expensive, but Competent...

The review from Stadt-Bremerhaven evaluates the iRobot Roomba s9+ as a highly capable, premium vacuum that justifies its €1,499.99 price tag through excellent cleaning performance, precise mapping, and advanced iRobot Genius features. While offering top-tier suction, the device's main disadvantages include its exceptionally high cost and a loud operating volume that is best managed through scheduled cleaning.

The Frandroid review of the iRobot Roomba s9+ and Braava jet m6 bundle highlights an exceptionally premium, high-performing ecosystem that excels at automated floor care through Imprint Link Technology, which coordinates vacuuming and mopping.

Review: iRobot Roomba s9+ robot vacuum

According to Que Choisir's expert testing, the high-end iRobot Roomba s9+ boasts exceptional cleaning performance on hard floors and deep carpets, largely due to its D-shaped design that allows the extra-wide brushes to efficiently reach corners and wall edges. Key advantages include its self-emptying Clean Base and powerful suction, though the unit is hampered by a noisier motor on high settings, shorter battery life compared to competitors, and a vSLAM camera system that struggles in low-light.
