Having just gone back to a bagged vacuum, I genuinely wonder why people ever accepted bag-less vacuums in the first place.

Aside from the “empty the canister out and watch all fine dust float back into my house” issue, vacuum bags function as one massive filter. It’s not physically possible to build a filter into a bag less vacuum that approaches the size or capability of the vacuum bag itself.

Bags are a razors + blades model. The vacuum is $100 but the bags are $30 for 3 if you buy the branded bags. Plus the suction on a bagged vacuum measurably decreases before the bag is full.

These days I have a roomba and a Dyson cordless stick vacuum for occasional use.

Bagless vacuums will typically have a pleated filter for the fine particles. Pleating expands the surface area.

Bagged vacuums also typically have pleated filters at the air outlet, after the bag.

Water works really well as a filter.
