Hello Firn,
Thanks for writing a review and we apologize for the inconvenience. While we don't know the model of your vacuum, this Floor Brush Accessory is ideal for large surface areas and general hard floor cleanup such as basements and garages. Also note that it has a bristle insert that is removable and configurable for either a pushing or pulling motion.
If you need further assistance, please call our Customer Service at 1-800-474-3443 from Monday to Friday between 8:00 AM to 5:00 PM Central Time or send us an email at info@ridgidvacs.com;
Thanks
