how to check a vacuum cleaner's air path, bag and filters
switch off and isolate the vacuum cleaner before checking normal detachable hose, wand and head connections for reachable debris. empty the bin or fit the correct bag, then follow each filter's own cleaning or replacement instructions and refit securely.

- ~ 15 min
scope: normal hose, wand and head releases, and bag or filter compartments only.
when to get help
- do not dismantle the motor, battery or powered hose. a blockage inside a powered hose, damaged filter, continued overheating or poor suction after these checks needs service.
steps
- disconnect before checking
switch off and unplug, or remove a detachable battery if the manual instructs you to. release the hose, wand and head at their normal connections. remove reachable debris without forcing rods or tools through them.
- empty the bin or change the bag
empty a bagless bin as instructed. for a bagged vacuum, fit the correct new bag with its collar properly seated. do not empty and reuse a disposable bag or force the compartment lid closed.
- check each filter's care instructions
clean or replace the filters as specified. only wash filters marked as washable, and let them dry completely before refitting. some exhaust filters need replacement rather than washing.

- why does my vacuum bag warning appear before the bag looks full?fine dust can restrict bag material before the bag fills. a blocked head, wand or hose can produce a similar warning.
- why does my vacuum cleaner brush stop turning?check wrapped hair and carpet resistance. a suction-driven turbo brush also depends on clear airways; powered and turbo heads need different assessment.
- why is my vacuum cleaner not picking up properly?check the bag or bin, detachable airways and filter care before blaming the motor. brush trouble may need a separate head check.
