why is my dyson vacuum pulsating


Dyson vacuum cleaners are popular due to their suction power and unique design. However, these vacuums can have an issue where the suction pulsates instead of remaining consistent. This problem affects the vacuum’s performance and makes cleaning difficult. It is important to know the reasons behind this problem and how to fix it.

Understanding Pulsating in Dyson Vacuum

Pulsating in a Dyson vacuum occurs when the machine’s suction intermittently turns on and off. The following are common reasons behind this problem:

Blockage in the filter or bin

A blocked filter or bin restricts airflow and reduces suction power. When the vacuum recognizes this, it turns the suction on and off, resulting in pulsating.

Clogged hose or wand

A clogged hose or wand also restricts airflow and disrupts the vacuum’s performance. This can be caused by the accumulation of debris or hair.

Faulty motor or wiring

If the motor or wiring of the vacuum is damaged or faulty, it can cause pulsating. This can be due to overheating or other issues in the machine’s electrical system.

These reasons affect the vacuum’s performance by reducing its suction power and making it difficult to clean floors and carpets effectively.

Troubleshooting and Fixing the Pulsating Issue

To troubleshoot and fix the pulsating issue in the Dyson vacuum, follow these steps:

Step-by-Step Guide on How to Troubleshoot Pulsating Issue

Check filter and bin

Remove the filter and bin from the vacuum and check them for any blockages or debris. Clean them thoroughly, and reassemble the vacuum.

Check hose and wand

Check the wand and hose for any blockages, debris, or damage. Remove any obstructions and clean the wand and hose thoroughly. You can do this by using a straightened coat hanger to dislodge any debris that may be stuck inside.

Check motor and wiring

If the problem persists, then you need to check the vacuum’s motor and wiring. Check for any damage or overheating. If you notice any signs of damage or faulty wiring, take your vacuum to a professional technician to have it fixed.

Tips on How to Avoid Pulsating Issue in the Future

Regular maintenance and cleaning

Regular maintenance and cleaning of your vacuum can help prevent pulsating issues. Remove any blockages or debris from your vacuum’s filter and bin and clean the wand and hose thoroughly after every use.

Using proper techniques while cleaning

Make sure you are using the appropriate technique while cleaning. If you are cleaning a hard floor, use the appropriate attachment for that type of floor. Vacuuming in proper direction can also help prevent blockage and reduce the chance of over heating.

Using appropriate attachments for different types of floors

Different types of floors require different attachments to clean effectively. Use the appropriate attachment for your vacuum when cleaning carpets, tiles or hard floors.

Adopting good vacuuming practices and performing regular maintenance and cleaning can help you avoid this issue in the future.

Why is my Dyson vacuum pulsating?

Here are some frequently asked questions:

What do you mean by “pulsating”?

A pulsating vacuum is when the suction seems to come and go, as if the vacuum is repeatedly turning on and off rapidly.

Is this normal?

No, this is not normal. Dyson vacuums are designed to provide steady suction without pulsating.

What could be causing it?

There are several possible causes, including: a clogged filter, a blocked hose, a full dustbin, a damaged motor, or seal problems.

How do I fix it?

First, check your vacuum’s filter, dustbin, and hose for blockages or clogs. Empty out the dustbin if it’s full. If this doesn’t help, try resetting the vacuum by turning it off and unplugging it for at least 30 minutes, then plugging it back in and turning it on.
