Verdict

The ECOVACS DEEBOT T9 AIVI is a high-end 2-in-1 robot vacuum and mop that delivers 3,000 Pa of suction power, powered by a 5,200 mAh battery offering up to 200 minutes of runtime. Its main characteristics include dual counter-rotating AeroForce rubber brushes, AIVI 2.0 visual detection technology capable of recognizing 15 types of objects, TrueMapping 2.0 LiDAR navigation, and an OZMO Pro 2.0 vibrating mop that scrubs up to 480 times per minute. The main pros are its exceptional pet hair pick-up, automated carpet detection with suction boost, advanced 3D house mapping, and quiet operation. However, cons include a relatively small 300 ml internal dust container and reduced obstacle avoidance reliability in dark or low-light conditions.

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

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

semi-circular

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

microfiber

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.

Ecovacs Deebot T9 AIVI Review 07/2026 | Video + Experience

The Testen mit Kopf review highlights the Ecovacs Deebot T9 AIVI as a premium, feature-packed hybrid robot, boasting excellent hard-floor cleaning, 3,000 Pa suction, and advanced AIVI 2.0 obstacle avoidance. While the robot excels at avoiding small objects and cleaning with its vibrating OZMO Pro 2.0 mop, limitations include a high price point, less-than-perfect performance on carpets, and inconsistent obstacle detection in low-light conditions.
