I was a vorwerk agent for a while but dropped the brand due to many issues, The main one been that ther reliability was not what it used to be yet the prices stayed the same. I was not impressed with the latest models including te Vk140 as to me it seamed a step backwards, Noisier and with a smaller bag, I also dont like the fact that you still ave to disassemble the whole machine just to vacuum the couches or corners. Or have to change heads to vacuum a wooden floor. To me it just did not make sense to buy it as a customer when there were better made more user friendly machines for half its price.
They used to get cross with me because I told the customers to keep there old Vk 122's because they were better machines instead of trading up to the new ones.
