Not sure what kind of dust you expecting, I'm pretty the purpose of vacuum/robot is to suck dust.

What's the lowest price for 1C? So far, lowest I see is RM699.

From manual, it is not recommended to put detergent inside… coz if got any residue, it is difficult to clean it. The hole very small and you can’t really clean inside.

Been using the 1c for 1 month… really satisfy with it. Probably the smartest gadget I ever buy. it can map the house, zone cleaning, auto reclean any part that it missed, smart routing (can move diagonally using the shortest path back to base!)

for those using xiaomi 1c, normally how much water it uses per cleaning? Mine is like 1/3 per tank for 70m2. Seems very less water used.

you mean the cloth quality or the cleaniness? for the cleaniness, i dont think very clean la... can you imagine, it use 1 cup of water to mop the whole house. still need manual mopping.

for me, it pickup a lot of hair compared to sweeping manually. not sure if it pick up ALL the hair, but for me it is still good.
