why is my bagged vacuum losing suction as the bag fills?
a full dust bag can restrict airflow, but a blocked hose or dirty filter can also weaken suction. check the bag as the exact vacuum's instructions explain before replacing parts.
switch off and unplug before opening the normal dust compartment. do not reach into the motor area or force the lid. a new bag must sit fully in its holder.
the linked guide concerns GN blue-collar bags: the pack includes 16 disposable bags, four motor filters and four hepa filters. red and green collar systems are different. do not empty, wash or reuse disposable bags. match each filter to the prescribed holder; a flat insert is not a substitute for a moulded cartridge unless that arrangement is specified. continued weak pickup needs the permitted hose, head and filter checks rather than more bags.
first checks
- check the exact bag family
use the full model, old collar and holder with the manual, not the series name alone.
