I live in a 1,700 square foot townhome - first floor is hard flooring and the second floor is all carpet. The carpet in my house is a typical contractor grade carpet that you find in the US with a low to medium pile and low density. I also have a Siberian Husky, so I have to deal with a lot of dog hair pretty much year round. I have both a Miele C1 Classic Turbo and a Dyson Ball Animal Origin. The Miele really excels at cleaning the hard floors, furniture, stairs, and tight to reach areas. Where as the Dyson really excels at cleaning the carpet, especially in the bedrooms where space is a bit tighter than the open floor plan on my fist floor. The Miele C1 Classic Turbo comes with the TurboTeQ head which can be used on carpet. And I find that it actually works really well - maybe even better than the Dyson in some ways. That being said I find that they Dyson is just easier to use on the carpet and in the bedrooms. Given your budget of $850 I would suggest that you purchase a Miele Classic C1 Pure Suction (hard floors only) for $319 on Amazon and a Dyson Ball Animal Origin (carpet only) for $329. Neither of these vacuums are perfect IMO, but together they make the perfect combination as you can use each for the task that they excel at. If you wanted to you could go with the Miele C1 Classic Turbo and the Dyson Ball Animal Origin which is the combination that I have. The C1 Classic Turbo comes with TurboTeQ head so you could use it on carpet if you wanted to. Price for that would be $399.
I was lead to believe the same thing you were. I purchased the Miele C1 Classic Turbo with the understanding that it would more or less be useless on the carpet. But I decided to try it anyway and really do not see what the issue is... If you had really dense or high pile carpet I could foresee it being an issue. But that is really not common in the US. I think that the folks that are pushing that powered head are vacuum sales people that are dealing with a different client base. And I could foresee that client base having very dense or high pile carpet.
Over the past 25 years I've owned three Dyson's (two uprights and one little hand-held. I purchased all three at Bed Bath & Beyond. When my last upright died I wanted to take it for repair (which I've done before) but it seems that there are no more repair places in my city. So when I saw a recommendation on CNN or the New York Times for a Dyson Original Animal upright for about the same price as having my existing vacuum repaired, I jumped on it. Cutting to the chase, it does not vacuum on carpet; I cannot drag it across carpet. It weighs a ton. Video conference with customer service, etc. Assembled correctly, moving parts functioning correctly. The upshot - they told me that it wasn't designed for my carpet (a mid-grade 1/2 inch twist which should NOT pose any difficulties for ANY vacuum). Customer Service guy told me to pack it up and return it. Ye gads! That is not a simple proposition. Anyway, I will never buy a Dyson product again. I know that I shouldn't personalize or emotionalize this but I feel seriously betrayed. EDIT: Three years ago after back surgery, I bought a no frills $400 Roomba which handles my carpet without any difficulty. I also use my mother's old 1960s-era GE canister vacuum in an emergency; the carpet attachment has been successful with several different grades and types of carpet that I've had. Mr. Dyson - you are a loser. I believed in you and I believed in your story once upon a time.
I have 2 broken shark lift away navigators one so far is just the head replacement and the other is the hose to the vacuum elbow connector but I can't tell if it includes the hose. Then I have an orange ball dyson I can figure out how to engage the beater bar. I bought the navigators refurbished. One lasted years the other more recent 1 lasted maybe a year. They keep making them so much less quality it seems. What can I do with these vacuums? I literally got a vacuum graveyard growing in my living room.
I just got a Dyson ball upright for $160 refurbished. That’s like half the cost of a new one and it’s through them so it’s legit. I know people gonna come at me for this cuz they’re not the best vacuum. But I just needed something decent. Not the best vacuum on the market. It works great though!
I have a corded Dyson ball vacuum for 5 years. Still going strong. Dont see the problem
Buy a 2013-2019 era Dyson Ball from marketplace. They are Bagless, very clean emptying process, they have an aggressive brushroll (which is my favourite feature on them), excellent suction. The brush roll has an on/off switch. They often sell at or below $250 on marketplace.
