First we test the cleaning ability
We use the cafe powder, broken toothpicks, paper bits, shredded paper and melon seeds
We remote control it to clean those and for one time the broken toothpicks and paper bits are perfectly being cleared
While for the cafe powder there are some left bc they are too tiny
also the paper bits and shredded paper
There are only small bit of cafe power left after the second time cleaning
We can see some shredded paper was being tangled on the brush, no surprise
All others were being absorbed to the trash can, the adsorption capacity is good
And for this one it can detect the carpet and increasing the adsorption capacity automatically
so that the dust inside the carpet can be cleaned out [You can hear the sound is much stronger]
Next we test the obstacle crossing ability
As for the 1.5cm height of books it can cross easily, while the official data said the limit is 2cm
That should be no problem for a small doorsill
We even put into a bunch of tangled wires and most of the times it can get rid of it
We tested for several times and the only one time it stuck we didn't record
That time because of the wire stick into the wheel directly and the vacuum stops immediately and reports function error
Though most of the times it gets rid of the obstacles but I suggest you trying to give a less complicate situation for it
Now we test the mopping function to see whether it will mess up instead or not
I put lots cafe powder here just to demo for you guys
The first time it shows the cleaning trail and feels sticky when touch the floor
It needs two or three more times
So I would suggest you don't be lazy, use the vacuum clean first and then use the mopping module when there is less dust
From my personal view, I'm pretty satisfied with the performance on these small experienments!
Though it still has those common issues a robot vacuum usually has, it tops most of them which I have reviewed in the past
Next let's see how it performs in reality
The room we are testing has a round wall and full of chairs but overall it is spacious
I placed some obstacles as well and also spreaded some cafe powder
After powering on, the machine immediately mapped out the room and circle cleaned first
And then it divides the room to several areas based on the position of furniture to clean
This algorithm is the best I've seen among all other vacuums so far
About half an hour later, it cleared the whole room for once including the cafe powder under the chairs
and without not so many repeated cleaning areas
After cleaning, it went back to the charging socket , everything is so smooth
Later I took the machine to my much complicated house to test
But it did a good job except those super narrow spaces it can't even get in, all other areas are being cleaned
Especially in this situation, it will circle around to clean the floor instead of turn around like other vacuums
In that way it can clear those "dead corners"
What's more, it has an amazing self-learning algorithm, like after the first clean, it will record those places that trap it and avoid them next time
And it gets faster in cleaning and charging
However in some situations like when it bumps into the light things it will push around
So for those who with pets.... the poop...
and chairs like this will always get it stuck
also for heavy curtain once the vacuum gets in, most of the times the curtain will block the laser sensor and stops it
Another one, since it can detect the carpet, why not put that sensor to the mopping module and avoid getting on the carpet once in mopping mode?
So my conclusion is with all those clean ability in complicate situation, the intelligent algorithm and the price, it is almos the best I've tested, even better than those much much expensive vacuums [The subtitles on the screen means: Buy ]
