FAQs - Frequently Asked Questions on Unlimited 9.

1) What can I do when my nozzle is blocked?
Cleaning the brush roller of the Unlimited 10.

First, remove the nozzle and hold it in your hand to check that nothing has got caught in it. Then remove the bristle roller, check it and remove any hairs.

2) What should I do when the MicroClean Sensor doesn’t work?
Cleaning the sensor of the Unlimited 10.

First, check if the MicroClean Sensor is dirty and clean it very easily with a dry cloth. You can also follow the tutorial on your display "How to clean the MicroClean Sensor.

If the case occurs on a carpet, check question 3.

3) Why doesn't the MicroClean Ring turn blue when I vacuum my carpet?
The Unlimited 9 vacuuming a carpet. A zoom shows microscopic particles being sucked in and detected by the MicroClean sensor.

The Unlimited 9 MicroClean Technology even detects when fine carpet fibres are being sucked up (besides dust and dirt). Therefore, if you vacuum your carpet and the MicroClean Ring does not turn blue even after multiple seconds, this indicates that the vacuum cleaner is still vacuuming fine carpet fibres. In this case, we recommend that you stop vacuuming to give your delicate carpet the best care.

4) What can I do if the performance of my device decreases?
Cleaning the filter of the Unlimited 10.

If you feel that the performance of your appliance is decreasing, check whether the filter needs to be cleaned. Not just the dust box, but the filter itself.

Watch the video to find out how to clean the filter:

5) What should I do when the dust box is stuck?

Press the button and try to open the cover manually with the other hand. Then check the hinge, the spring and the position of the seal and clean them. After some time of use it also becomes smoother.

6) What can I do if some dust & dirt is stuck above the compression seal in the dust box?

Switch on the appliance in Turbo Mode and move the compression slider forth and back while it is vacuuming. By this, the dust will be sucked into the front part of the dust box. After that, you can empty the dust box as usual.

7) Why does my display not show the maximum of 60min runtime?

The maximum runtime is stated for the handheld only in eco mode, which in line with similar appliances from competitors. This duration is calculated without attachments such as the tube, nozzle, or accessories.

When the device is switched on with a specific attachment, the displayed runtime is adjusted accordingly to accommodate the configuration.

8) The charging progress of my Unlimited 9 is not shown on the display.
User interface of the Bosch Unlimited 9 is shown with its Display and buttons.

During charging, the display is in standby mode to save energy. You can check the charging progress by pressing one of the “< >” buttons. The display will then illuminate again and show you the charging progress in percentage.

9) What if nothing happens on the display after the ”< >” arrow buttons have been pressed during charging?

Once the Unlimited 9 is fully charged, the device shuts off – to save energy and to protect the battery lifetime.

So if pressing the “< >” arrow buttons doesn't wake the Unlimited 9 to show the charge percentage, you can be sure it's 100% charged. If the display shows any percentage below 100 (e.g. 95%), the Unlimited 9 will continue to charge until it is fully charged and then automatically switch off as described above.

If you need the device urgently, you can also disconnect it from the power supply before it is fully charged and then simply use it with the indicated runtime.
