I love bag vacuum Vs. bagless. The room gets cleaner and leaves my garage trash area dust free.
These are Q/C bags, not Q bags. They will fit but are larger than C bags. Because of this, you must fold the bag to fit and reduce the space available in your bag compartment, requiring more frequent bag changes.
If your machine requires C bags, better to purchase 3rd party bags since you are paying a high price for only using 1/2 of the bag.
