The Flat Out floor nozzle is the perfect addition to any Dyson vacuum cleaner. I use this as a main jet nozzle now for my DC23 Animalpro, because it can be run simply much lighter than the nozzle with rotating brush. Contrary to many comments I've read here, the nozzle of the vacuum cleaner fits perfectly and locks exactly as any other. Now, even dirt under the refrigerator or washing machine does not stand a chance. No matter what floor, the nozzle makes a good figure.
