I decided to make this thread to ask a pretty interesting hypothetical question that had been floating around in my head for a long time now:

What if on bagless vacuum cleaners, the clear dust bin was made using glass *instead of* plastic?

I was inspired to ask this after seeing how most front-load washing machines have a glass window on the door.

Right off the bat, I can see one big pro to this scenario: No more fogginess! After just a few uses, every plastic dust bin will get permanently fogged up due to the rapidly spinning dirt. A glass bin would no longer have that issue, and would remain clear as day for years to come.

However, I can already see some cons to this. First off, owing to the fragility of glass, the bin could potentially shatter if large, hard debris, such as rocks and coins, were picked up. Companies would be in the business of selling bins if this issue were at large.

Second, because glass is heavier, especially if tempered, the bin, as well as the vacuum, would naturally have additional weight. This would make the vacuum more difficult to manuever, not to mention the need to carry a heavy and fragile dust bin to the trash can in order to empty it. This brings me back to con #1, where if you were to accidentally drop and shatter the glass bin, the whole vacuum would become unusable until you purchase a new bin.

This alternative material would apply only to the clear bin. The rest of the vacuum, including the separation system (either filtered or cyclonic), would still be made out of plastic and probably, some metal (such as the wand). This might make the vacuum more expensive.

What are your thoughts, opinions and additional questions on this hypothetical scenario?

Perhaps an inner glass sheet to prevent scratching, then plastic on the outside.

Glass

If broken would cause injuries. They make glass stronger by adding to it. They added chicken wire at our school to glass. This genius kid kit it and ripped his hand all up.

Could you imaging how heave they would be? The dust cup would weight a ton and make the vacuum itself a lot heavier.

Glass can also get cloudy as well. But just like with plastic, they can be treated. However it just doesn't make any sense to go for glass over plastic. Vacuflo's clear plastic bins I think are the best because I've never seen one get cloudy over the years.

About the Glass breaking..

One coutner to that would be Tempering it or using Prince Rupert Methods on the Glass. But then, it would still be heavy and is a Tail were on the Bin, the Glass would explode into little shards! Yikes..

The dust cup can be polished with car wax, after washing it obviously, to remove scratches and protect the plastic. It will get dirty again of course. Stopping the scratching would be to make it out of textured, frosted plastic, but then you couldn't see in detail the bin's dirt level of course.

I think the secret though is to change the way the cyclone path operates, so it is not swirling the dust around over and over, but just depositing it straight down. Dyson's bins seem to never get scratched up so badly as something from a Eureka or Hoover.

I think the net result of glass dust cups would be a lot of vacuums in dumpsters with missing or broken dust cups. But then again, maybe over time, people would come back around to the wisdom of disposable filter bags, which I personally wouldn't have a vacuum without. Bagless vacuums are a scam.

Alright

Thanks for all the replies on this hypothetical scenario. I agree, glass would indeed make a vacuum much heavier and therefore harder to maneuver.

As for cloudiness and wear, I have a set of glass mixing bowls which have seen their fair share of use over the years (scratch marks from whisks being used on them). So I was wrong, the use of glass actually won't fix the fogginess issue.

Human, I can't imagine picking a vacuum out of the trash and seeing its dust cup missing or broken. That would further complicate repair matters by having to buy a whole new dust cup. And no, I will never change my views on bagless vacuums.

I won't ever change my view on bagless vacuums either. I hate them with a passion.

I am a bagged vacuum all the way. Cleaning those perminent filters for the so called
benifit of bagless is just not true.

1. They clog up fast espeicially here in the snow belt. all that salt and ice melt
clog up the filter fast.

2. They are a pain to knock the dust out of them (now you are covered in all that
dust) or wait for them to dry after washing them.

I have used several of them in the commercial office cleaning market. I won't consider them. I have better things to do that drive all over town cleaning filters for the vacuums whem my own people are to "alergic to dust" to clean them.

Weight, extra cost, fragile nature, and liability risk would make glass prohibitive for MFRs.
Like kirby519 said - just use a bagged machine, change the bag when needed and be done. Little mess, no fuss. One bag can go a long way (at least in a Kirby).

While I prefer bagged vacuums myself, I'd disagree that bagless vacuums belong in the dumpster at least not all of them since I do think some are trash. Besides the cons of bagless machines, there are also pros as well over bagged machines. Bagless bins can show you what you're picking up, bags aren't worth changing out at some places, and some machines can maintain the suction power that you pick up. For example, my sister has pets that shed ALOT. Unfortunately bags would just be too expensive for her to always have to change out more often than most people. Another example is if you're using a bagged vacuum and can't see what you're picking up inside, then you're likely still leaving dirt behind. And the last example is if you ever noticed that at wood shops their central dust collectors are cyclonic, they prevent from clogging up the system. That's where James Dyson got his idea from. Even my wood shop requires a bagless dust collector because I'm not always clogging up and changing my bags out often. But I also still do care about motor protection and filtration so the least I can do is to connect a bagged system to a seperator so it'd be a win/win for me.

Don’t dogpile on me for this either..

But I agree with some of the Points Panasonic Vac made despite me also being a Big Fan of Bagless (Good Airflow) Not all of them are bad and just some of them are. I just hope I’m not gonna cause a huge storm by agreeing with Panasonic Vac.

I do agree with the points you've made, since I'm also a huge fan of bagless vacuums. Seeing the dirt that I've picked up gives me a sense of satisfaction and confidence, knowing that my vacuum is doing its job. On the other hand, if I were using a bagged vacuum, I would not be as satisfied, since the dirt is completely hidden away from view.

Another point to make is how both types of vacuums deal with the dirt. Bags compact the debris that has been picked up. Bagless bins, on the other hand, fluff it all out, thanks to the rapidly spinning air. This action explains why the bin fills up quicker.

Bagged machines not picking up---The Kirby Avalir2 I now have the bag was half filled in its first trip on the carpet in the rental house I in now.Next I am going to try the carpet tool with my NSS M1 and see what it picks up!You get a workout with the NSS carpet tool since it doesn't have a beater bar.When I used the Av2 on the staris again picked up half filled bag of dirt.Have had to replace the bags in my 2 Av2's twice so far.

Honestly if that were my place, I would've went over with a ClearTrak afterwards to pick up what the Kirbys left behind. That first video about the ClearTrak was from a guy that does professional carpet cleaning, he says he's visited homes that've been vacuumed with a Kirby yet he'd always pick up dirt with the ClearTrak that Kirbys leave behind. And I testify that when my grandparents were around, they had a Dirt Devil bagless that'd pick up stuff both of their Kirbys left behind. Even with their Kenmore that's bagged but has a dirt sensor on, it'd also reads showing that it's picking up stuff left over from the Kirbys and the Kenmore is one of the least performing machines I've used. Now I'm not saying that bagless can outclean bagged vacuums, it's just that as what the carpet cleaner guy pointed out that you need to let vacuum do it's work by picking up stuff until not anymore dirt goes inside. Unfortunately no vacuum is going to get all the carpets cleaned completely not even the ClearTrak, but the fact of the matter is that bagless has the advantage of letting you see by what you're picking up inside the clear dirt bin. There's no way to tell with bagged machines and just feeling the bags afterwards isn't very convincing to me.

I don't trust using a NSS M1 PIG to clean my house either. Not to mention it's such a monstrosity machine to carry and pull around inside a house. I'd also go back over with a ClearTrak afterwards as well, guaranteed it'd get whatever the PIG leaves behind. But if I had to use a bagged machine and something that's large as the PIG, I'd rather use a Numatic NaceCare 380 as the PIG is just outdated for me.
