Frequently Asked Questions

Why does my Dyson vacuum lose suction?

Loss of suction is often caused by blockages, dirty filters, or a full dustbin. Regular maintenance like cleaning filters and clearing obstructions can restore performance.

How often should I replace the filters?

Filters should be cleaned every 1-3 months and replaced every 6-12 months depending on usage. Using compatible filters like the 3Pack Pre Filters or V10 Filters helps maintain suction.

Can I wash the filters?

Yes, most Dyson filters are washable. Rinse them with water, let them dry completely for at least 24 hours, and then reinstall. Do not use detergents or hot water.

What should I do if cleaning doesn’t fix the suction problem?

If cleaning and replacing filters don’t help, check for blockages in the wand, cleaner head, and cyclone. If problems persist, contact Dyson support or a professional repair service.
