Dreame L40 Ultra - ServiceDig

Cleaning performance on carpet
the average amount of hair they were able to pick up was 77% after two runs
Cleaning performance on hard floors
for hard floors they were all nearly perfect at pet hair pickup
Dust-bin emptying
the option to adjust the number of times in the app that the robot returns to its dock to empty its bin
Front-facing camera
like the ability to go check up on your pets or video calls
Obstacle & cliff avoidance (robots)
it wouldn't really be the best robot vacuum for pets unless I included their ability to avoid that problem
Overall opinion
number two the dreamy l40
Scheduling feature
use the scheduling feature that every robot vacuum has and run it as many times as you need to each week to keep the hair under control

Dreame L40 Ultra Review - Robot Vacuum Mop Combo Review

What We Loved

Airflow (CFM)
airflow again was very similar to the dreamy x40
Battery runtime / Charging time
extremely good battery life — 194 minutes on low power and the highest score I've seen yet
Cleaning performance on carpet
it was above average with deep cleaning carpets
Cleaning performance on hard floors
very easily sweeping up all the debris we tested it with on both hard floors
Coverage efficiency (how completely a robot covers a floor)
vacuumed and mopped in about 43 minutes versus the average 66 minutes
Edge-cleaning effectiveness
automatically extending side brush that makes it much better at sweeping debris from corners
Mapping/navigation accuracy (robotics)
navigation was good, slightly above average with efficiency and coverage
Mobile-app functionality & reliability
Dreamy app has all the features… great on iOS but pretty low score on Android
Mop lifting system
mop pads also lift up 10.5 mm automatically when it senses carpets which keeps your carpets dry
Mopping performance (robotic or wet-dry)
in our dried-on stained mopping test the L40 did much better than the X40, scoring 119 (higher than average)
Obstacle & cliff avoidance (robots)
significantly above average, tying for second place overall in obstacle avoidance
Price
significantly cheaper than the x40
Self-cleaning mop function
washes its mop pads with hot water and dries them with hot air automatically
Self-emptying base
automatically emptying its dust bin into the included bag
Suction power (air watts)
its suction power was above average in our tests
Under-furniture clearance
Robo Swing is used to get under some hard-to-reach places
Value-for-money
an amazing ranking for its price

Just Okay

Noise level
odd noise when it was washing its mop pads — a lot of squeaking

Needs Improvement

Hair-wrap prevention / anti-tangle tech
had more hair tangled on the 7-inch hair test than any other robot we've tested so far
Pet-hair pickup efficiency
wasn't all that good with picking up pet hair from carpets either
