We tested the bagless variant of the BISSELL Zing canister, which uses the model code 2156A. You can see its label here. Another variant of the BISSELL Zing Canister is currently available with a drastically different bagged design, referred to as the 2154A variant. The 2154A bagged variant has a functionally larger dirt compartment, a lighter design, and a simpler two-stage filtration system. Due to these differences, we can’t say if they perform similarly.
If anyone comes across a model that’s differently equipped from the variants listed above, let us know in the discussions so we can update our review.
