my dyson dc07 sounds like a boeing 747,why?

the dyson DC07 is very old now, you may prefer a DC25, or a DC24 (THE SMALLER VERSION OF THE DC25) which is much quieter, also it would be better for you, as it is the ball version, so it is small, light and manouverable. also that won't smell, as it has the brand new Hepa-filteration system which is now washable and you won't need to buy new ones, it is also MUCH easier to empty and its expelled air is 150 times cleaner than the air you breathe.
The DC-07 is quite old now, so thats probably why, visit the dyson website and take a look at the DC24
it may seem a tad pricey, however it's very much worth it, i have one myself.
As for the name, well the DC stands for dual cyclone and the number represents the model
Hope that has helped!

yours faithfully
