Vacuum cleaner whistles

My vacuum cleaner whistles. What should I do?

If your vacuum cleaner whistles, this is usually a sign that your device can’t suck in sufficient air. Often, it’s the dust container or bag that’s full. Check these first and exchange them if necessary. If that’s not the case, it could be that the device is blocked. Check that the exhaust filter, the nozzle, the tube, the suction pipe, the telescopic pipe or the floor attachment aren’t blocked. Follow the principle of exclusion and attach each piece one by one. Has the sound changed or is the vacuum cleaner still whistling? If the vacuum cleaner still whistles and you can’t solve the problem yourself, contact Bosch Customer Service on the service phone number 603 7950 9338. You can reach us around the clock, 7 days a week. We’ll be happy to help if your vacuum cleaner is whistling.
