In most cases loss of suction power is caused by the dustbag being full, but other causes can be an object being stuck in the nozzle, tube or hose or the EPA / HEPA exhaust filter or motor protection filter being dirty.
Make sure the suction power knob has been set to maximum suction power. If this doesn’t help, follow the steps mentioned below to restore the suction power of the vacuum cleaner:
1. Make sure the dustbag is not full.
2. Make sure the hose, tube and nozzle are not blocked by an object.
3. Make sure the exhaust filter is clean
4. If the above checks have not yielded the cause, replace the dustbag as in that case the pores of the dustbag are probably clogged with fine dust.
NOTE: When you use the vacuum cleaner to vacuum ash, fine sand, lime, cement dust and similar substances, the pores of the dustbag become clogged. As a result, the dustbag full indicator will indicate that the dustbag is full. Replace the disposable dustbag or empty the reusable dustbag, even if it is not full yet (see chapter 'Replacing/emptying the dustbag').
IMPORTANT: Only use Philips disposable dustbags or a Philips reusable dustbag with this appliance. Other dustbags might damage the motor of this appliance. Never reuse a disposable dustbag.
If the above solution(s) did not help to solve your problem, please contact Philips Consumer Care.
