Of course Vax are made in China, as are iPhones, but plenty of people have moaned and complained about iPhones being made in China, especially the conditions the workers are put through. They have nets around the buildings to catch the workers if they try to comet suicide. I need say no more.
There is no denying it, China is not like Korea and Japan when it comes to quality and giving the customer what they want. As much as it is the fault of western companies investing in China, there is a lot of spying that goes on at Chinese facilities, especially at car plants.
The Koreans and especially the Japanese have a knack similar to the Germans when it comes to creating something to the best of their ability. Quality is at the forefront, just look at what this ethic has done to their car industries. China have been making products for nearly as long as the Japanese and Koreans, yet the quality is still lacking in many aspects, yet the cost of the products do not equate to what you get. Hoover still want to charge £300 for a Chinese made vacuum. You can get a decent Miele or top of the line Sebo for that cash.
And also, dirt in bags does rot. You are picking up skin cells, dust, moulds and allergies among food crumbs and in some cases animal hair, which does decompose, although having S class and HEPA filters does more or less eliminate it.
One thing I have pondered over is although my dysons performance is very good, what is the point of picking up all them allergies and fine particles if they are going to fly up in the air and cover yourself in them? Even taking the bin outsides, I still get clouds of dust. It obviously depends on each household. At least with a bag you just wait for it to become full, seal the bag in which ever way and dump it.
Long story short, I can see the arguments on both sides, but as of recent, I am preferring bags.
