This looks so good on paper, and it's got spinning mop just like my roborock which I likes a lot. But what's the catch? Anyone has experience with this model or lefant?

No experience with this model, but have a lefant dumb robot vacuum. It's fine, we use it to vacuum our cabin when we aren't there to keep dust down. Gets caught on vents a lot and the app isn't great (at least for my model), but for baseline keeping things dust bunny free it's fine. I think I paid like $100 18 months ago for that one, I'd pay $150 for this.

edit to add, mine does not have 5g band, or self emptying, mapping, or mop.

I've been shopping for a robo vacuum replacement for a while. For a vacuum with all these features, at this price, it's just too good not to give it a try. It's has 4.2 stars, but by far the majority of the negative reviews are from the European market.
US reviews talk about great customer support. And the negative reviews are mostly small potatoes. Every vacuum I've had needs some help sometimes. So I'm in for one. Thanks!

FYI, few reviews on the Amazon are totally false. Someone says it doesn't wet the mop before starting the mopping job. I checked their manual and not only it wets the mop but app allows you to configure the time for the bot to return to base station for rinsing and resuming the mopping. This way your robot is not mopping with the same dirty mop. Mopping is the key feature I am getting this. 20K suction is not heard of. If I am getting even half of it, I will be satisfied. Yes, the entire package looks too good to be true in terms of the tech and features it provides at this price point. I took a chance and will give it a try. Worst case, it will go back to Amazon. Bought it with credit card that offers extra year of warranty for extra peace of mind.

C38KIWCX still seems to work. Sometimes it can take a couple of tries for Amazon to accept codes. And if you're using the Amazon app don't forget to tap the arrow to apply the code.

I grabbed one even though I have an Ecovacs T90 Pro at this price; why not? It can clean my enclosed porch.

I don't think those reviews are false. I think what they're trying to convey is that THEIR vacs didn't wet the mop. In other words, defective.

YouTube reviews are a bit sus. It's free returns though so probably safe to try out.
