| Bagged |
| The bag itself serves as a filtration device and often counts as several of the 'stages' of the vacuum's total filtration level.
|
|
| As the bag fills, particles caught in the fibers of the paper obstruct air flow decreasing the suction power and stressing the motor. The effects can be minimized by replacing bags when they are half full.
|
|
|
| The bags require frequent replacement increasing operating expense and maintenance.
|
|
|
| Proponents of the bagged style often site convenience as a major benefit. Disposable paper bags are easy to change and offer minimum dust blow back when disposed of properly.
|
|
|
| Bagless |
|
| Proponents of the bagless design often report convenience as its number one benefit! Dirt cups offer a convenient and easy way to dump the dirt without the hassle of replacement bags.
|
|
|
| Despite the easy of use and convenient dirt cup designs, dumping the dirt into a receptacle may generate an undesirable cloud of dust blow back.
|
|
|
| Without the additional filtration of the bag, the exhaust filter(s) tend to clog more frequently. This increased replacement frequency tends to offset any cost savings from not having to buy replacement bags.
|
|
|
| Because even a partially full bag can obstruct air flow, decreasing the suction power and stressing the motor, the bagless design may help maintain maximum suction efficiency and prolong motor life.
