Yes, I am very impressed with the agitation on this vacuum. The only other bagless vacuum I have used that has similar agitation is the Bissell powerglide lift-off, but that has very poor manoeuvrability, a terrible dust seal and feels cheaply made and the suction is not as strong as the DC41 MK2 even with a 1400 motor. Also, the Bissell I had obviously has no self-adjusting soleplate, it was not as consistent across floor types as the dyson. It also had a handle which was ridiculous and moved up and down about 5 inches, to suitable for someone who is 6'7. Furthermore, since using the DC41 MK2 and having it a few days, the ball has "broken in" and it easier to use now, and you really can tell a difference. It is much more manoeuvrable than any other vacuum with swivel steering. It is also the best upright I have used on hard flooring. It picks up every spec of dust and dirt in one swipe. It is also so easy to use the hose. Literally in 3 second you are using the dusting brush or tangle-free turbine.
I have used a DC04 and DC07. The DC07 was my aunties she got in around 2004 ish I cant remember, but I am sure there was something wrong with it, as when you turned it on a reclined it, it took about 3 or 4 minutes for it to start picking up dirt, even though the brushroll was spinning, I think it was something to do with the adjustable floorhead taking a while to adjust to the carpets. It always picked up tons of dirt and had incredible suction.
My mothers old DC04 she got in the late 90's I think, was a tank. Nothing ever broke in it during the 11 years she had it (she now has a Sebo X1 which she likes in terms of build quality and performance, but moans and complains about its bags)
Another thing that persuaded me to buy another vacuum, and a bagless one, is my dislike of my Sebo Felix using bags. I had a MR lift-away previously, and before that a series of other bagless vacuums form Bissell, vax and so on. After about 2 weeks of using the sebo with a new bag, it stinks, even when paying over £20 for a charcoal filter. It really does smell, and the only option is to change the bag when it is practically empty. That coupled with my mother pointing out that having a bag full of animal and human hair and general dust and dirt decaying in a bag for weeks at a time, made me want to go for bagless again. I know we have many many bagged fans on here, but I am starting to wonder how people can put up with them. Buying bag fresheners or putting carb soda in them is dodgy for the manufacturers as they only want you to use a certain type, or using their fresheners, costing even more money, and at best covers up the smell rather than getting rid of it, as since having the Sebo, I have broken out in rashes more often now. When it has an empty bag, the sebo is lovely and I still love it, it is a great vacuum, but having it a few months, the novelty is wearing off.
And like dyson does say, perfectly reasonably, they don't test these rating when the bag gets full or is full. I can vouch that the filter on my dyson it still completely dust free, there is no surface dust whatsoever, and I only washed it out once to see if there was any fine, white dust accumulating, which there wasn't.
There really is not much I dislike about this vacuum. I genuinely love it.
