From the Dyson manual:

“This machine has two filters, located as shown. It is important to check your filters regularly and wash at least every month according to instructions, to maintain performance.

Please note:The filters may require more frequent washing if vacuuming fine dust.”

It’s not really lying if you talk about what doesn’t matter.

Dyson vacuums claim they don’t lose suction.

While suction may be great for drinking through a straw, it has little to with cleaning. Neither does “cyclonic action”.

Vacuum cleaners mostly use air flow or rapid moving air and a filter which catches the particles and removes them. So does the Dyson just like any other vacuum.

Don’t think Dyson doesn’t know. They even have a label on the side of the vacuums that tell you to clean the filters for optimal cleaning. So don’t worry about those clogging filters that cause any Dyson model to lose air flow. Dyson vacuums still have plenty of suction if you want to use them as a beverage container. Does any body have a straw?

The Rotho Twin TT vacuum cleaner not only has the convenience of a hepa filtration bagged system that doesn’t blow dust, germs, bacteria, and highly allergenic fecal matter from dust mites, but an aquafilter system that allows you to deep clean with water while dry vacuuming. This system doesn’t lose airflow so you get the cleaning job you thought you were getting with dyson dc24
