You may have selected a low suction power setting or the dust bucket may be full. Reduced suction power can also be caused by a dirty filter or an object stuck in the nozzle, tube, or hose.
Make sure the suction power knob has been set to maximum suction power. If this doesn’t help, follow the steps below to restore the suction power of the vacuum cleaner:
1. Empty the dust bucket and make sure the filter cylinder is clean. The filter cylinder is located inside the filter cylinder case which is placed in the dust bucket.
2. Make sure the exhaust filter is clean.
3. Make sure the motor protection filter is clean.
4. Make sure the hose, tube, and nozzle are not blocked by an object.
You can find more information in the user manual. If the above solution did not help to solve your problem, please contact Philips Consumer Care.
