Review on 🧹 Enhance your Cleaning with Koblenz Genuine Polishing Brushes Pack of Two by Pamela Hefton

Not suitable for Koblenz P4000. Each brush at the base of the Koblenz has eight "teeth", and the brushes supplied with the Koblenz have eight corresponding "notches". However, these polishing brushes only have four notches (see photo) so they don't fully land on the base and fall off.
