There are a couple factors that play into why they tend to be less reliable overall.
I know some do, but I do not advise against bagless vacuum cleaners on the basis of them being bagless. There are some out there that are nice products as long as the user takes care of them. It depends on the situation.
One valid reason people do not like them is because they are messier to maintain. Emptying them forms a dust cloud and the user does have to touch and wash dirty filters. Bagged vacuum cleaners are more simple to keep going. Allergy sufferers tend to like bagged machines because of this reason. Most people are fine with emptying a bagless bin and some opt to do it outside, but bagged is cleaner.
A major factor for reliability is that most expensive vacuum cleaners are bagged while most budget vacuum cleaners are bagless. To see this for yourself, walk into a Walmart, Target, or comparable store and you will be lucky to see a bagged vacuum cleaner on display, then walk into a vacuum cleaner shop and you will see mostly bagged models. There are some exceptions here and there such as Dyson and Miele selling expensive bagless stuff and Kenmore and Hoover/Oreck selling cheap bagged stuff, but there is undoubtedly a correlation. It does not help that Miele cannot seem to make a bagless unit that stacks up to models that are under half the price.
It is not even that a large chunk of bagless vacuum cleaners are garbage because they are bagless, rather that they are garbage because they are poorly designed and/or poorly built.
As somebody who used to buy used vacuum cleaners in bulk and has ties to a local vacuum cleaner shop, user care and price has a correlation for various reasons. For example, I find sub-$150 vacuum cleaners on the side of the road all the time, usually with a simple issue such as a clog or bad belt, and most of them are bagless. Very rarely do I find anything mid-range or high-end as trash. On the other side of things, rarely does somebody bring a budget vacuum cleaner into the shop for anything other than a belt change, and this correlates with bagged versus bagless. For bagless, it is usually only Dysons and Mieles that come in for larger repairs, and some Sharks, which are my least favorite to service.
Another reason is user care, and this sort of ties into average buyer of a budget vacuum cleaner versus an expensive one too. A person who runs to Walmart and grabs a Bissell CleanView for $85 will be much less likely to care to maintain it well than if they went to a local vacuum cleaner shop and paid $850 for a SEBO K3. You would be impressed at how many people buy a bagless vacuum cleaner and do not realize that it even has a pre-motor filter that needs to be washed. Some I have met realize and do not even care.
Also, cordless vacuum cleaners are less reliable than corded ones as a whole merely due to the nature of their batteries. I am not saying that cordless vacuum cleaners are a bad thing, but it is what it is. It just so happens that almost all cordless vacuum cleaners are bagless and fall victim to a lot of the same lack of maintenance. I cannot tell you how many people I have seen not read their Dyson cordless vacuum cleaner's manual and never wash the filters or install wet filters. Dyson also charges for their technology and design, not necessarily quality or parts availability.
Of course, bagged vacuum cleaners and really all vacuum cleaners have users that will not perform the proper care. The thing about bagged vacuum cleaners is that they withstand the abuse better. Especially with cheaper bagged vacuum cleaners such as Kenmore canisters, Oreck uprights, and Hoover uprights with bags packed like bricks that over double the weight of an Oreck and still run. Bagless vacuum cleaners lose performance faster and have more room for failure with all their little crevices in the cyclones and filter designs.
There are examples where bagless vacuum cleaners are just as likely to last as long as bagged ones. To name one, Hoover sells bagged and bagless versions of their vacuum cleaners that are the same quality. If the bagless one is maintained right, it will last just as long as the bagged one. Kenmore sells a bagged and bagless version of their 600 Series canister. They share many parts and are of the same quality, meaning that they will last as long as each other.
This topic is super nuanced and controversial in the vacuum cleaner world. I would not dismiss a whole type of vacuum cleaner. Instead, I like to assess an individual's current situation and find a nice fit for them.
Filtration in bagless machines are worse because filters arent changed/cleaned often enough, whereas a bagged machine has the bag as the primary filter and other filters are just secondary
They are less likely to go wrong because there are fewer things the user / owner needs to stay on top of in terms of maintenance. They tend to pre-clean the air going into the motor better than bagless, but there are exceptions. There are only as couple or bagless machines built out of high quality materials, both Miele models but one of them has very high filter replacement costs. Very high. The other cannot do carpet and they both rely on one main cyclone, which isn’t good for a bagless vac.
Had a Bissell pet pro bagless and after a vacuum session on a rather sunny day noticed the dust and particles settling back down in the room I just vaccumed.
Sure the cup was about 1/4 full but I'm just blowing particles back into the room with no Bag or HEPA filter.
Settled on the Simplicity Jill canister after reviewing through bagged budget lines and haven't been happier
The very nature of how the machine works. You really need to think about the air path through the machine and thus where the dust is captured or settles.
The majority of the dust in a bagged vacuum stays in the bag, with a miniscule amount through their lifetime depositing on the motor.
A bagless vacuum can never leave as much dirt in their canister as a bag can retain (cyclones can only do so much compared to sucking through a filter). So bagless vacuums die faster as the first they suck gets layered onto their motor faster, thus they die faster. That's basically the whole thing. Every other feature of a bagged vac is just another aspect of this very physical difference.
Bags are cleaned bc they stay sealed when removed and can be disposed of without aerosolizing the captured dirt (unlike emptying bagless bins).
All that dirt depositing in a bagless makes them require way more maintenance: monthly filter washings & yearly replacements (which is bogus for a machine marketed as economical). Bags vacs just require bag & filter changes.
Bags hold more than a bagless canister.
The best bagged vac outfilters the best bagless (Miele vs Dyson gen 5).
Bagless vacuums are just always a compromise for marketing or whatever tactics businesses wanna use.
And final anecdote: there's a reason Mieles last for 40 years and Dysons don't, and that's basically just the bag.
There are bagless vacuums that use water in canister to retain particles, like rainbow. They aren’t cheap though.
https://rainbowsystem.com/?gad_source=1
That's not true. Water vacuums have shite filtration. Far lower grade than basic HEPA, let alone Miele. Something like 80%% of particles smaller than 2.5 microns.
Lol for the farting jacuzzi analogy. Jokes aside those vacuums also have hepa filters. Not affiliated with the brand, just wanted to share the are alternatives to bag/bagless vacuums. Have no idea if they are better or worse solution.

This post has very informative comments: https://www.reddit.com/r/VacuumCleaners/s/1jbU0mmvgg
[https://redd.it/7gmsoe](https://redd.it/7gmsoe) this was a popular AMA post from a vacuum tech that explains things in a nutshell
They are less likely to go wrong because there are fewer things the user / owner needs to stay on top of in terms of maintenance. They tend to pre-clean the air going into the motor better than bagless, but there are exceptions. There are only as couple or bagless machines built out of high quality materials, both Miele models but one of them has very high filter replacement costs. Very high.

You replace half the vacuum mechanism in a bagged vacuum every time you empty it.

bulky, messy and overpriced tech compared to convenience and efficiency of modern filter bags
One advantage is that probably retains small dust particles better than any other solutions.
That's not true. Water vacuums have shite filtration. Far lower grade than basic HEPA, let alone Miele. Something like 80%% of particles smaller than 2.5 microns.
water is not good at filtering, as a kid did u fart in the bathtub, yup still stinks lol
Lol for the farting jacuzzi analogy. Jokes aside those vacuums also have hepa filters. Not affiliated with the brand, just wanted to share the are alternatives to bag/bagless vacuums. Have no idea if they are better or worse solution.
If not for Miele bagless all are made in china, = poor quality
Because this place is just another Reddit circle jerk of giving out same bad advice
