Aesthetic design & finish Eovax has definitely refined the aestheticThey've also added this nice brushed metal finish
Coverage efficiency (how completely a robot covers a floor) navigation is solid
Debris pickup performance handled everything I threw at it
Dried-on stain cleaning performance can actually scrub off those sticky spots that have been sitting there for days
Ease of use day-to-day, this thing just works reliably and cleans effectively
Fine-dust capture regular dust and dirt
Generic Performance most well-rounded robotic vacuum I've used yet
Large-debris pick-up Cheerios that my daughter threw on the ground
Matter smart-home protocol support Matter support here is genuinely useful
Mopping performance (robotic or wet-dry) The real star of the show is the Osmo Mop roller systemreally makes a difference
Motor efficiency / runtime-per-watt (cordless) new blast suction system is more efficient
Pet-hair pickup efficiency pet hair
Self-cleaning mop function roller that can wash itself as it goesapply pressure to your floors
Voice-assistant integration (Alexa/Google/Siri) basic controls work great through smart home ecosystems
Just Okay
Hair-wrap prevention / anti-tangle tech new comb feature built into the main brushworks pretty well, though it's not perfect
Mobile-app functionality & reliability used the app notifications anywayran into some frustrations during initial setup
Suction power (air watts) suction power dropped from 18,000 pascals to 16,600 pascals
Transparent water tank design They remove the transparent water tanksit doesn't really bother me
Needs Improvement
Assembly and Setup took me about 20 minutes to get everything sorted out
Edge-cleaning effectiveness vacuum occasionally stumbled picking up debris at the edges next to carpets or door thresholdssometimes it would leave a bit behind
Mapping/navigation accuracy (robotics) mapping feature made some pretty significant errors when it first scanned my home
Price Yes, it's expensive
Threshold crossing ability vacuum occasionally stumbled picking up debris at the edges next to carpets or door thresholds
Airflow (CFM) the X9 got 27 CFM, which is one of the highest airflow scores we've ever seen
Cleaning performance on carpet it got an 89%, which is tied for the highest score we've seen from a robot vacuum that has a lifting mop mounted under the robot.
Cleaning performance on hard floors sweeping up everything from fine to extra-large debris from both surface types very efficiently and without scattering
Edge-cleaning effectiveness extends its mop roller to the side when it's near edges for better edge coverage, which it did well with in our tests
Hair-wrap prevention / anti-tangle tech it got a perfect score with 0% of the hair tangled
Liquid/spill pickup (wet-dry models) they can actually pick up wet spills without spreading them around
Mapping/navigation accuracy (robotics) getting a higher-than-average navigation efficiency score.
Mobile-app functionality & reliability Ecovacs makes a top-tier app that is easy to use with lots of features and lots of control over the robot and bin behaviors
Mopping performance (robotic or wet-dry) it got 158 points out of a possible 184 points on that test, which is one of the highest scores on record
Obstacle & cliff avoidance (robots) it got 19 points out of a possible 24, which is higher than average.
Pet-hair pickup efficiency it picked up 93% of the hair, which is much higher than average.
Self-cleaning mop function will automatically wash the mop pads with hot water, dry the mop pads with hot air, refill the clean tank, and empty the dirty water tank.
Self-emptying base has a fairly large 3-liter disposable bag for dry debris, which Ecovacs says can contain 3 months of debris before needing to be replaced.
Suction power (air watts) its suction power was also way above the average amount too.
Voice-assistant integration (Alexa/Google/Siri) The app has the Yiko virtual voice assistant built in
Just Okay
Battery runtime / Charging time it actually had a lower-than-average battery score
Dust-bin capacity it also has a lower-than-average internal dustbin capacity at 220 milliliters.
Threshold crossing ability It's limited to thresholds about 20 mm high, which is the standard amount.
Under-furniture clearance its height is around 3.8 inches, which is a touch higher than average
