What reviewers say about the Dreame L20 Ultra
Three whitelisted hands-on reviewers (TechRadar, TechHive, Pro Tool Reviews) all praise the L20 Ultra's strong suction, thorough edge-reaching mopping and near hands-free automated base station, while flagging its ~$1,500 price plus ongoing consumable costs. None published lab measurements, so all verdicts are qualitative. They split on obstacle handling: TechHive and Pro Tool Reviews found object recognition/avoidance excellent, while TechRadar called small-object and cord detection 'hit or miss'.

Where reviewers disagree Obstacle avoidance and object recognition split sharply: TechHive found the system 'almost clinically accurate' with nothing getting sucked in and Pro Tool Reviews said it 'navigated this maze of chairs like a boss', while TechRadar called small-object detection 'hit or miss', with the robot repeatedly snagging on string, wires and shoelaces.

there was not a single time that the Dreame failed to pick up something it should have done, and it even collected some items I expected it to miss.
the robot didn't always accurately identify smaller objects like pieces of string, wires, and shoelaces, and would end up getting itself caught when it sucked these things up.
As mentioned the L20 Ultra's minimum sound is louder than conversation, and you could use this thing as an alarm clock if you wanted.
It left our floors virtually spotless after its vacuuming and mopping runs.
it did an outstanding job of picking up all the dirt in its path, while an almost clinically accurate object identification system made sure not a single cord, sock, or any other small object got sucked in.
Its base station takes up a lot of space
The L20 Ultra has some of the strongest suction power we've yet seen.
The Dreame L20 Ultra navigated this maze of chairs like a boss.
Certainly the high price of the Dreame L20 Ultra keeps it out of the hands of many.
