Main trade-off
Eureka WhirlWind NEN110A
No motorized carpet or sofa brush
Head-to-head
Choose Eureka NEN110A if a larger dust cup and an integrated crevice-and-dusting tool make cleanup easier. Choose BISSELL Zing 2156A if its current offer is better and the 2-liter cup and 16-foot cord fit your home. Both are bagless suction-only machines, with no motorized carpet or sofa brush in these packages.
Before you choose
NEN110A's 2.5-liter cup has 25 percent more nominal volume than the 2-liter Zing. That can favor Eureka for bulky dry debris, yet fill lines and the way hair packs down prevent a reliable emptying-frequency prediction.
What this is based on
0.5 divided by 2 equals 25 percent more nominal volume. No usable-volume or compaction measurement.
Main trade-off
No motorized carpet or sofa brush
Main trade-off
No powered brush for embedded carpet hair


Compare Eureka WhirlWind NEN110A and BISSELL Zing 2156A for bagless hard-floor cleanup, bin size, tool access and pet-home limitations.
These are close alternatives for dry debris on hard floors. Compare cup volume, attachment handling and the offer rather than inventing a suction winner.
Winner by situation
Both provide bagless suction-only cleanup.
Eureka specifies 2.5 liters, versus 2 liters.
Eureka keeps the two-in-one small tool integrated.
Neither has a motorized mini tool.
The reviewed sources do not establish that requirement for either.
What matters in practice
NEN110A's 2.5-liter cup has 25 percent more nominal volume than the 2-liter Zing. That can favor Eureka for bulky dry debris, yet fill lines and the way hair packs down prevent a reliable emptying-frequency prediction.
0.5 divided by 2 equals 25 percent more nominal volume. No usable-volume or compaction measurement.
If each floor pass leads to baseboards and sofa gaps, Eureka's integrated crevice-and-dusting tool is a concrete convenience. The Zing includes tools for those jobs too. The distinction is retrieval and handling, not proof that one cleans the corner better.
Workflow deduction from the included accessory arrangements.
Either can fit a mostly hard-floor apartment with loose debris. If the same home has a rug or sofa holding embedded fur, both packages lack powered agitation for that difficult surface. The location of the pet hair should override the apartment label.
Surface-and-tool constraint shared by both packages. No apartment household-size assumption.

Eureka, NEN110A
A bagless suction-only canister with a two-in-one crevice and dusting tool kept at hand. It is a simple choice for dry debris in a home dominated by hard floors.

BISSELL, 2156A
A small bagless canister for dry messes on hard floors and simple rugs. A flip switch changes the floor nozzle, and its cord rewinds after short cleanup jobs.
Meaningful differences
| What changes | Eureka WhirlWind NEN110A | BISSELL Zing Bagless 2156A | Why it matters |
|---|---|---|---|
| Dust cup | 2.5 liters | 2 liters | Eureka provides 0.5 liter more nominal capacity. |
| Small tools | Integrated two-in-one crevice and dusting tool | Crevice and dusting tools | Eureka's integrated arrangement can reduce retrieving separate pieces. |
| Floor cleaning | Suction-only combination head | Suction-only combination head | Neither has a powered roller for embedded carpet hair. |
| Cord storage | Automatic rewind | Automatic rewind | Both remove the manual cord-wrapping step. |
| Filtration certainty | Sealed HEPA not established | Three-stage filtration, sealed HEPA not established | Neither should be selected on an unverified sealed-allergen-system assumption. |
What you give up
Recommendation switch
Choose Eureka WhirlWind NEN110A. The larger nominal Eureka cup is the relevant specification, without a guaranteed interval gain.
Choose BISSELL Zing Bagless 2156A. The verified common functions may meet your needs without paying for a larger cup.
What matters in practice
Eureka integrates its crevice and dusting tool, which is useful when a floor pass repeatedly leads to edges and gaps. BISSELL also includes small cleaning tools, so this is a handling difference rather than proof of better corner pickup. Think about the attachments you actually retrieve during a normal session instead of comparing motor numbers alone.
Eureka's stated cup is half a liter larger. If you collect bulky dry debris, that is a useful reason to consider it. It does not overcome a wrong floorhead or prove fewer stops by the same percentage. Both remain suction-only bagless models, with no documented sealed HEPA system or powered hand brush in these reviewed packages.
