Hi, I have this one red carpet and I've just purchased the s7 maxv ultra, it's cleaning and mopping everywhere else pretty much as what defines as fine but when it comes to this carpet, it just won't clean it very well. My other robot from Dyson can clean it in one go but roborock s7 maxv ultra can't do it in 5 runs, how is this possible? Could there be something wrong? It's just a standard red carpet, nothing special. Maybe the sidebrush is not strong enough? I just replaced it. Or is it the suction? Please, if anyone knows what I can possible do or check to fix this, then help me, I would rather use this robot since it's much more advanced and its also expensive, I think it should be able to do this.
