By vacuuming without a bag, you save costs on vacuum cleaner bags. All dirt ends up in the dust cup while you vacuum, which you can then easily empty above the trash can. Bagless vacuums come in all shapes and sizes. This is why it's important to find out which bagless vacuum best suits your needs. Have delicate floors in your home, for example? Choose a model with a parquet brush. If you have pets, go for a version with a turbo brush.
