Many vacuums also have a secondary filter here to remove more dirt that’s escaped.. As you might have guessed, this is a simplified version of what’s happening inside a Dyson or other cyclonic vacuum cleaner.

When comparing vacuum cleaners, it’s important to understand that decibels.are not a linear scale.

Doubling the decibel level doesn’t double the noise intensity.Instead, an increase of 10 decibels means that the noise is actually 10. times.In other words, a vacuum cleaner with a 60dB noise output is actually 10 times quieter than a vacuum with 70dB.

And a 60dB vacuum is.quieter than one with an 80dB output..

This can make comparing vacuum outputs more difficult.

What’s the actual difference between a vacuum with a 68dB noise intensity and a 72dB noise intensity?Step 1: Remove The Floorhead.

Before you start trying to clean the Vax Blade 4 brush bar, it’s best to remove the floorhead from the machine.You can do this by pressing the blue button at the bottom of the wand..

There are two reasons for this:.It’s much easier to work with the floorhead when it’s not attached to the main vacuum..
