You can tell that there is something like glue on the ground by the way the residues of the yellow stuff stay in clear line and shape. Otherwise it would spread around by the brush. Make the test again and then, without any camera cut, let the Henry suck up any residues of the Dyson!
Before I brought my Dyson, I had a ”Hetty”, the reason I chose to switch over, was because we have three flights of stairs, and it was a pain to carry the vacuum up and down the stairs so we bought the Dyson. After three months of use, I can honestly say I will not be buying another one. The Dyson is awful on kitchen floors and on wooden floors. It gets stuck often and I have to keep manually unblocking it. I have actually gone back to using my “Hetty” I will be considering buying the Henry stick version. I’m sure people have great experiences with Dyson, but from what I’ve experienced it is not as good as advertised
Bags on a cordless dont make much sense. Once they start getting filled suction will be reduced as not enough surface area at top area to compensate like a larger bagged unit. Also large wheels on wood floors will scratch them
