In my assortment I don't have the brush for carpets because I don't have any carpets.
For carpets I would need: Digital Motorbar™ brush.

I hope I've been able to reply "late" sorry

The main attachment supplied is universal and works equally well on carpet, parquet, hard floors, etc.
If you want to deep clean carpets, it is best to hire an appliance designed for this purpose. This cannot be solved with a special attachment.
