The suction efficiency (excellent), the relatively high noise, and ease of maintenance are fairly comparable in the 2 or equivalent model. The difference will be in finishes that are slightly off the Dirt Devil, and on the quality of materials that are less robust. In use, the flexible relatively rigid tends to overturn the product on carpet or carpet, the advantage is that it will not bend. This drawback and for a really advantage is its relatively light weight (less than 5 kg).
In the end, efficient vacuum, relatively noisy but in the standard cyclone, correct finishes, materials but slightly recessed, and quite content rates make this a cleaner alternative to consider facing a Dyson certainly quite blameless, but 2 times more expensive too.
