People tell me; “My bagless vacuum picks up so much dirt!”
The bagless vacuums are very deceiving as to how much they pick up.
The process fluffs the debris making you think you picked up a lot when, in actual fact, you picked up very little.
A 9’x12’ section of carpet can look clean and hold 84 pounds of dirt. What you left in the carpet is more substantial than what you picked up.
A bagged vacuum compresses the dirt and a bag holds substantially more than a bagless dirt chamber.
To clean your home, you need a vacuum with a good strong motor, an aggressive brush roll and a bag to trap the dirt.
(These days, a HEPA filtration bag is what makes sense.)
