When a vacuum manufacturer claims that their bagless vacuum cleaner is the best vacuum cleaner because it features “no loss of suction,” it doesn’t really mean anything when comparing vacuums! That manufacture is probably talking about the “sealed suction” capability of their bagless vacuum cleaner. Sealed suction is measured with the air intake completely closed and no airflow.
With no airflow, none of the dirt will make it from the bagless vacuum cleaner head to the vacuum bag or container. It doesn’t matter if it’s an upright vacuum or canister vacuum. So, airflow is just as important if not more important than whether the vacuum claims to have great “no loss of suction” capability.

Bagless Vacuum Cleaner: “No Loss of Suction” is Meaningless?
All Vacuums Suck
Whether a bagless vacuum is going to pull the most dirt from your carpet or not is really a combination of sucking power plus airflow. Many vacuum manufacturers now make “no loss of suction” claims, but most of them also lose airflow!
Bowling Ball Magic
What about vacuums that can lift a bowling ball? Don’t they offer the most powerful suction? Won’t they do a better job of cleaning my carpet? Lifting a bowling ball with a vacuum is really a parlor trick.
The simple suction of a suction cup can lift weights greater than a bowling ball without any power at all. It is the suction connection and not the suction power that carries the weight. Vacuums that advertise that they can lift a bowling ball are just trying to dazzle you with hype.
Clogging Is Universal
If you cover a vacuum’s filter with dust, the vacuum will clog and stop the airflow. So, no matter what the claims are about a vacuum’s “no loss of suction” capability, in the end they all clog and stop vacuuming.
What you need is a combination of suction power and airflow to insure you get a vacuum that will meet your cleaning needs.
Airflow is an important specification to compare when choosing a bagless vacuum cleaner. Airflow is typically measured in cubic feet of air per minute (CFM) and measures how much air is flowing through your vacuum’s system.
All other specifications being equal, a vacuum with a higher CFM will usually do a better job of removing dirt from a carpet.
Forget “No Loss of Suction”
There are other important specifications that you can use to compare vacuums such as water-lift capability and amperage, but loss of suction power is not something you really need to compare.
The Right Comparison
Compare airflow in CFM and buy a canister vacuum with a specification of 100 CFM or more or an upright vacuum with 60 CFM or more.
A great airflow coupled with an average 10- to 12-amp vacuum will do the job just fine without any hype.
