As I have have said before and will say again, science and theory cannot defeat actual testing. Also, there is always a way to make one machine look better and one look worse. Therefore anyone that makes claims that are quite out there, well, I have a hard time believing them. Also, vacuumfacts. The reason why cyclones clog up is as follows, the discharge channels are very small and get clogged, then dirt starts to pile up in them and it eventually reaches the cyclones. The cyclones are then clogged. I know that overfilling the bin is technically "abuse". I know that the full line should be respected, however it can be very hard to look at the bin constantly when you are vacuum and paying attention to other things. If that is abuse then my Electrolux d338 was put through, well, whatever you can describe filling the bag to a brick and still using it, sucking up small amounts of water, getting literally thorwn and many,many other things. That Electrolux never gives up or throws a fit, it just works. I timed how long it takes to unplug and rewind the cable, shake out the bag and put it away. ! minute and 15 seconds. Pretty good for a corded vacuum. and as for these "dangerous, . I have noticed in your Kirby review that you demonstrate it without the tech drive on and go on complaining about it being "impossible to push".I would rather a simple two position switch for techdrive then battery's running out of charge and everything else. I agree with your points about the belts needing replacement and the fan potentially getting damaged, although I have never seen a broken fan on any of my 7 kirbys. You were lifting from the top of the handle instead of the carrying handle at 3:11. Is winding a cable really that hard. At 4:50 you complained about it being hard to use and push. Techdrive is very simple to use, flicking a pedal to turn techdrive off is really quite simple. Manually adjusting height is very simple, I never have a problem with it. I agree that the tools can be a bit fiddly, although I must say that you had the height adjustment on the lowest setting making it almost impossible to use. Kirby's use a low moisture foam based shampoo system. Dyson zorb and Kirby foam work almost exactly the same. One gets a pass and one is terrible though, I see. I agree that the handheld machine was not a good idea... However I just use the hose. I can convert a Kirby to tool mode in less than a minute, it just takes some practice. I am sure that any Dyson is a learning curve just the same. I like headlights as I can clean down a hallway without having to stop and turn the lights on. A V10 is quieter I know, although it has an ear pearcing whine. I showed my uncle the Kirby and he said that it was a wonderful vacuum and that it sound terrific. I also showed it to my school friend who said that he has to have one and that it is the best vacuum he has ever seen. If the Kirby is unable to be sold in the eu because of noise, what about the avalir 2 still being sold. They have fixed that problem already. Bags that stink. I have used many, many vacuums in many environments. I have never seen a smelly Kirby. Kirby's don't really need that much servicing. People just want to make a quick buck. I have never seen a Kirby that was not repairable. In New Zealand you rarely see glued down carpet unless it is in a commercial environment or garage carpeting. At 16:10 you use a Kirby in upright mode on hard floors. That is why they sell a hard floor pad. at 16:35 you simply need to put the height adjustment up a notch. You show Dyson videos showing a statement that dyson's are designed to last 10 years. Meanwhile you are using a 25+ year old Kirby and complaining about durability.I am in middle school and have never had a single problem understanding or managing a Kirby.
