Bagged or bagless canister, which is better?

Specialist community consensus (r/VacuumCleaners) leans toward bagged canisters like the Miele Classic C1 for filtration and lower long-term mess, with several reviewers calling bagless cleanup and filter maintenance a chronic annoyance. Bagless models like the Eureka canister are cheaper upfront but, per high-trust testers, vary widely in cleaning performance.
