What is Better a Bag or Bagless Vacuum?
It’s hard to tell which is better since there are pros and cons to both types. While bagless vacuum cleaners have a distinct convenience, there are some benefits to those with bags.
Bagless, as the name tells, doesn’t have bags but dust cups. This means you don’t have to keep buying and replacing bags to operate the vac. All the dust goes into the dust cup, and you just empty it into your trash can once it’s full.
However, the process of emptying the dust cup can be a bit messy depending on the bagless vacuum cleaner you choose. Some open harder than the others and might get that dust back in the air.
So, there are some benefits and setbacks with both of the types. One isn’t better than the other, so it’s up to you to choose which would work better for your cleaning needs. We encourage that you check out our guide on bagged vacuum cleaners as well.
How to Choose the Best Bagless Vacuum Cleaner
Because bagless vacs are growing more popular, almost all major brands have already come out with at least one model. The ones we mentioned above such as Shark, and vacuums by Bissell, are the most popular and best-selling brands on the market.
When buying this type of vacuum cleaner, it’s important to consider the brand you’re buying from. It has to be a reliable name in the industry, so you’re certain that they’ll stand behind their product, honoring the warranty deal they offered.
By choosing a reliable brand, you’re also opting for better customer service and an altogether better experience.
Suction power is the most critical when looking for the best bagless vacuum cleaner.
Your bagless vacuum cleaner has to be strong and able to pick up all the dirt and dust.
Still, vacuums differ from one another when it comes to power, so there’s some difference between upright and handheld vacuums.
Some pick up even the finest dust but can’t suck in larger particles like dog kibble. Others have such powerful suction that they cannot be used on carpets because they keep getting stuck.
Consider the type of floors you have and how powerful you’d like the cleaner to be. Some vacuum cleaners even have several strength modes allowing you to use them on all flooring.
Much like all house appliances, bagless vacs range in price depending on the brand, attachments, power, and several other factors.
You should decide on your budget before you get into choosing a bagless vacuum cleaner. By thinking about how much you’re willing to spend, you narrow down your choices. This makes it easier to pick out a single model.
The good thing is that there are so many different vacuum cleaners on the market. There’s a vac out there for everyone’s pocket since you can find high-end and expensive units, as well as some more affordable ones.
Weight is a significant factor since it’s directly connected to maneuverability.
Cleaners range in weight, so some have less than 8 pounds while others weigh as much as 18 pounds. It depends on the motor, materials used for the chassis, dust cup capacity, and other attachments.
While this is again up to you to choose, make sure to think about it in detail. Do you have stairs? Are you looking to clean above the floor? Where will you store the vac? These are all the things that weight has a significant impact on.
Attachments are equally as crucial since they can make the cleaner more convenient and versatile. Most bagless vacuum cleaners come with a brush roll, but several also have additional accessories to help you clean different areas.
Typical attachments you might come across are a crevice tool, dusting brush, upholstery tool, an attachment for stairs, car interior, pet hair, etc.
While you can probably do a fair job without these attachments, they certainly make vacuuming easier and more efficient. Even if you don’t care about them as much, make sure to opt for at least one tool made for hard-to-reach areas.
The Type of Floor You Have at Home
Some cleaners perform equally as well on all types of floors. However, some might do better on bare flooring as opposed to carpeting and vice versa.
Think about the type of floor you have at home, so you know right ahead what to look for. For example, if you have only hard floors and no rugs, you don’t need as much suction power, but you need gentler brush tools.
If you have different floor types, look for a versatile bagless vacuum cleaner. Height adjustment is also a good idea if you have both bare flooring and carpets.
There are several things you should think about if you have stairs at home. First is probably the weight of the bagless vacuum cleaner since you don’t want anything too heavy to drag up and down.
Another critical thing is the type of floors are on the stairs. Is it carpet or hard floors? Think about if the cleaner of your choice can tackle the surface.
Also, make sure to get some appropriate attachments such as a stair tool or at least a crevice tool. Overall, we think a handheld vacuum is great for stairs, especially if there’s a crevice tool included.
Frequently Asked Questions
Are bagless vacuum cleaners good for pet hair?
A: You should pay attention to the filtration system the vac comes with. Bagless models are as good as any other for pet hair, as long as you keep the brushes, filters and canister clean and empty.
There are even some bagless models made specifically for pet owners. Those have full-size dust bins, better filtration, and specialized tools.
Are bag or bagged vacuum cleaners better for allergies?
A: Bagless vacuum cleaners can pick up fine dust just as well as those with a bag. However, when there’s a bag, you simply pull it out and throw it in the garbage.
When there’s no bag, you have to empty the canister into your trash can which can sometimes be a bit messy. Some of that dust and dirt might return into the air and fall back on your floor during this process.
As you can see, bagless vacs have many benefits, and they’re among the most convenient options on the market. They eliminate the need for bags and with that the cost of having to purchase them all the time.
While they have some setbacks and might not be the best for allergy-prone people, they’re undeniably convenient.
One thing to keep in mind is that a bagless model isn’t necessarily better or worse because it doesn’t have a bag. Its suction power doesn’t depend on that.
Think about your needs and preferences, and we’re sure that you’ll find at least one bagless vacuum for you on our list. Regardless of the type of floors you have, you’ll quickly get used to the convenience of these cleaners.
