I can not speak for the Dyson V6 but I purchased the Hoover 22v cordless. My grandmother always purchased Hoovers and told me as a young person that Hoover always made a good machine. She had one for 32 years and had me replace the belt once. I purchased the cordless hand held questioning if it was going to be as good as the Dyson. Let me tell you for $145.oo it is twice its worth in gold. If you use the extension for ceiling and window cleaning don't be disappointed if the charge only lasts 30-35 minutes maybe less if you have it on high. I use this on my hardwood floors/ the utility washroom and even clean the cars out with it. It just sucks the dirt right up. Used it yesterday on my brick fireplace where I had drywall replaced in my dinning room. Dust is Dust to it and it picks it right up. Bye Bye Dyson....many other items out there half the cost and does the job.
