Are you asking about what is currently for sale today?
For department stores brands, I'd have to say either Dyson and some Hoovers. Most of their models can last a decade or so and both clean well. I practically abuse my Dyson DC14 and I have no doubt it will last me 10 years.
Department store vacuums are quite cheap anyway, so I'd rather have a brand I get in a vac store. Riccar, Sanitaire and Royal come to mind. They are use metal parts and are biased off time-tested designs. Santiare probably gives you the most for your money, but Riccars and Royals are excellent carpet cleaners.
Now if you are referring to contemporary machines in general (Post-1980) I would have to say Hoover. Even the cheap Hoover Elites last 20 years. I have yet to find a Hoover that doesn't clean well.
Consumer Reports constantly polls members and readers on their experiences with the products they have bought. Here are the latest results from their questionnaire regarding brand reliability for vacuum cleaners:
Kirby was among the least repair-prone brands of upright vacuums while Simplicity and Riccar were among the more repair-prone. Among canister brands, Dyson and Kenmore were among the least repair-prone and Electrolux was most repair-prone. That's what we found when we asked almost 96,000 readers who bought a vacuum between 2007 and 2011 about their experiences. The graph shows the percentage of models for each brand that were repaired or had a serious problem. Differences of less than 4 points aren't meaningful, and we've adjusted the data to eliminate differences linked solely to age and usage. Models within a brand may vary, and design or manufacture changes might affect future reliability. Still, choosing a brand with a good repair history can improve your odds of getting a reliable model.
In Which's recent tests, SEBO was number 1 for uprights, Miele was number 1 for canisters, Bosch was number 1 for their larger appliances. The Germans are just taking over!
And another for reliability-NSS M1-The NSS folks have an M1 machine in their factory lobby that is over 50 yrs old and still works-they will even take it out of its display case and demo it.The NSS machines are the easist to service-brushes in minutes,fan replaced in minutes,even the bearings-with an arbor press-30 min job.
Being that thee are 300 HOOVERS in the house... And, we ALL know, any N CAnton HOOVER, (Convertible, Constellation), etc are still runing very well. Some of the newer ones are ok too. I've HAD to run "other" vacuums (for various reasons). Wasn't thrilled.
Having a lot of one thing doesn't make it reliable...
Sanitaires & Eurekas, Kirbys, Compacts & Tristars, long lived and reliable, proof that very few design changes over the years is better than radical alterations and modification (well, maybe not so for Kirby, but they still use the same basic design)...
Everybody says Kirby is reliable, I'm not doubting it. But do think that most cleaners would be of they were sold with annual tune-ups.
Sebo have been one of the most reliable uprights cleaners I have seen. I used to use them cleaning NHS hospitals/clinics and they suffered some major abuse, but keep going..
I heard about Sebo, however, most places do not sell them. Seems just online. Which one's are well known, that people are aware of? How are the Aerus or Pro Teams? I see them in my gym
In my own opinion I believe that just about any make or model will last the test of time. As long as its taken care of, maintainanced it will last.
But I have seen some run into the ground, never taken care of that will last also. They just won't die and thats Kirby, Miele, Electrolux (original), Hoover (original).
GM1982 - the older SEBO uprights are basically the same and go under the Windsor vacuum branding (commercial cleaning company.) Also there's www.sebo.us
Anything is reliable if taken care of; I say are the MOST reliable:
Kirby
Filter Queen
Sanitaire/Eureka
Hoover (some models)
Electrolux/Aerus
Royal (some models)
Compact/TriStar
Kenmore/Sears (some models)
Craftsman/Sears
& the LEAST reliable:
XXX
Durabrand
Shop Vac
Euro Pro
Shark
Kenmore in the consumers reports I have always found to get a good rating. While they are not the se quality like those of the 70's 80's and 90's (my favorite time periods) they still come with some great features. While I can't speak for everyone I thin a lot will agree that speciality brands like Rainbow, Aerus/Electrolux, Kirby that type of thing will always be a good bet. If you are going for store bought stick with the names that are household names like Hoover and Eureka.
if you are talking about cleaners sold at stores, then i would probably have to say dyson as long as you take care of it. they are good machines, not very heavy[especially the smaller models]. and do a great job at cleaning you're carpets.
I presently have a Miele Capricorn that serves quite well. However, I have never had a machine I bought new -- cheap or pricey -- die on me in inordinate time. I think a vacuum's track record depends a lot on reasonable care AND use by it's owner and also being in tune with the machine. That said, I have noticed a drop in regard to quality -- and standards -- by a lot of vac makers that we once depended upon for affordable cleaning equipment.
It should always also be considered that as many manufacturers outsource re components comparisons can be dubious. Does my Bosch really "out clean" your AEG when they both use the same Wessel Werks tools and Amtek motors?
As well, I've seen the most touted brands end up on the trash heap because users assumed the bigger the name, the higher the price, the less they had to concern themselves with. So very wrong.
It's my strong belief that if bags aren't used until jam-packed and filters are regularly cleaned or replaced before they just downright clog up you get longer life and reliability out of your machine. This also applies to bagless machine for which I'd add you should always keep an eye open as to debris mucking up the cyclonics process. If the air in that area isn't flowing properly you definitely will find dust gathering more quickly than usual on filters.
My avatar is the Lux "Intelligence". It's manufacturer is Lux International, part of a European conglomerate I believe. I have been trying to get hold of one employing 120-volt A/C current level since I first saw it's predecessor, the Lux Chrome.
I actually tracked down a salesman -- in the Bahamas no less -- but it was a no go as he would have had to order several from the company to sell me the one machine I wanted. Also, they are not under the radar as far as Aerus goes. There's some sort of territorial agreement between them I'm told. It's web page is below and I've attached an additional YouTube URL.
alot of the older machines are pretty reliable with care, but, just because they are still running as good as new, doesn't mean they were good carpet cleaners when they were new. For a good carpet cleaning upright, eureka/sanitaire, kirby, and royal are "tops" in my book.
It is a nice looking machine. I like the fact that it has a regular handle instead of the pistol grip type and I also like the look of the woven hose. From the video link attached, it appears to have been built with good filtration too.
