Why does my Kärcher Vacuum Cleaner have poor suction or the full bag light is on?

Poor suction or the full bag light turning on in your Kärcher Vacuum Cleaner can be due to several reasons: * The dust bag may be full, in which case you should replace the bag. * The hose could be clogged; remove and clean the hose. * The neck might be clogged; disconnect the floor head from the vac tank and clean the neck. * The bag may not be properly installed; re-insert the bag correctly. * The exhaust or motor filter may be clogged; clean or replace the filter. * The back cover might be leaking air; re-install the dust bag, motor filter, and back cover to ensure a tight fit all around.
