Since the power of the vacuum cleaner does not reach the power of conventional vacuum cleaners, I bought a mini-turbo brush (narrow), also connected through an adapter. More suitable for furniture, as the spiral brush is too narrow for carpet. I was just afraid that the wide turbo brush would not pull - there would not be enough power to sufficiently spin the turbo brush. Personally, I lack a power regulator, or at least a switch on a long handle - the convenience would increase significantly. I know this, because there is a conventional vacuum cleaner with smooth power control on the handle. I understand that this would increase the price of the vacuum cleaner, but it would be possible to make at least a p-through switch on the wire and fix the wire on the handle with the switch near the thumb.
