What is pulsating mode on my Dyson vacuum?
Pulsating mode is a feature on some Dyson vacuum models that helps to detect and clear blockages in the vacuum’s airflow path. When the vacuum detects a blockage, it will automatically switch to pulsating mode, which involves rapid changes in suction power to help dislodge the blockage. This mode is usually accompanied by a distinctive pulsing or throbbing sound.
In pulsating mode, the vacuum’s motor alternates between high and low suction power to create a back-and-forth airflow that can help to loosen and remove blockages. This mode is designed to help clear Hair, string, or other debris that may be clogging the vacuum’s airflow path. If your Dyson vacuum is pulsating but not clogged, it may be a sign of another issue that needs to be addressed.
Why is my Dyson vacuum pulsating if it’s not clogged?
If your Dyson vacuum is pulsating but not clogged, there could be several reasons for this. One possible reason is that the vacuum’s airflow sensor is faulty or dirty, causing the vacuum to mistakenly detect a blockage. Another possibility is that the vacuum’s filter is dirty or clogged, reducing airflow and triggering the pulsating mode. It’s also possible that the vacuum’s suction power is set too high, causing the motor to overwork and trigger the pulsating mode.
In some cases, the pulsating mode may be triggered by a blockage that is not immediately apparent, such as a small hairpin or a piece of dust that is stuck in the vacuum’s airflow path. To troubleshoot the issue, try cleaning the vacuum’s filter and airflow sensor, and check the suction power setting. If the problem persists, you may need to consult the user manual or contact Dyson’s customer support for further assistance.
