The KOBOT RV337 does a good job to “suck out” all if not 99% of the dust that is in my room. Seriously speaking, I wouldn’t know so much dust has accumulated in the dustbin if I didn’t bother to open it.
If you are lazy to sweep, mop or vacuum the floor, the RV337 is definitely a good helper which will just doing it’s job without intervention (it even auto charge when battery is almost flat). In fact you would let it do the job when you are out of your house.
