Air inlet blocked by water probably, tiny hole located at the rubber cap

Don't worry it's smart enuff not to fall off stairs

Don't need to poke it, just make sure no water inside the hole, use cloth or tissue. Don't care about water outlet hole, wet the mop cloth before install. If can't fix maybe have to ask your supplier for support.

Ahh? I thought need to poke it. LOL.. i try to dry the hole, and see again if it works..
It's been 1 week i never topup water into the tank

idk why people need lidar maybe for complex home

but for normal simple condo/apartment, my xiaomi works fine, many dust collected and hairs. run 3x per week. it practically outperforms me. only qualms are i have to mop the corners
