Eureka NEN110A vs 3670M: Which Routine Fits You?

Choose the NEN110A for a reusable cup and automatic cord rewind. Choose the 3670M for bag disposal if you accept manual cord storage. The bagged 3670M still requires motor-filter washing and drying, so bags do not make this a wash-free choice.

The buying question

Do you prefer bag disposal or a reusable cup, and how much does automatic cord rewind matter?

The WhirlWind combines cup emptying with automatic rewind. The Mighty Mite combines replacement bags with manual cord storage. Both retain washable-filter care.

Quick verdict

When to skip: You need a vacuum with no washable-filter routine.
When the recommendation changes
  • You need both bag disposal and automatic rewind; neither of these configurations combines them.
  • You cannot accommodate washing and fully drying filters; neither removes that obligation.

The differences that matter

Disposal And Required Filter Care

Eureka WhirlWind NEN110A (blue)

Empty the cup after each use or at the max line. Wash the sponge filter monthly or more with use; allow 24 hours or until fully dry before refitting. Do not operate without it.[1, 3]

Eureka Mighty Mite 3670M (yellow)

Replace Style MM bags, folding the closure flap before removal. Check the motor filter and rinse as needed; reinstall only when all parts are completely dry.[4]

What this changes: Choosing bags changes disposal, but does not eliminate filter washing and drying. Choose the WhirlWind to avoid replacement bags, or the Mighty Mite to discard a bag. Neither routine establishes lower total upkeep cost or labor.[3, 4]

The better fit depends on your priorities

Cord Pack Away

Eureka WhirlWind NEN110A (blue)

Automatic rewind: switch off, unplug, then use the rewind button.[1, 3]

Eureka Mighty Mite 3670M (yellow)

Manual cord-hook storage; rotate the swivel hook to release the cord.[2, 4]

What this changes: If wrapping the cord is your main objection, choose the WhirlWind. If bag disposal matters more, accept the Mighty Mite’s manual cord storage. These two preferences can point to different machines.[1, 3, 2, 4]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Pay more only for the disposal and pack-away routine you prefer. Avoiding bags does not establish zero maintenance cost or lifetime savings.

No reliable price-history baseline is available for a timing recommendation.

Limitations

  • No measured pickup, allergen-containment, noise, durability, emptying-frequency or total-cost advantage is established.
  • The selected yellow 3670M listing is labeled “with 5 bags”; that is the selected offer configuration, not a manufacturer-verified package count. Check the current seller’s contents.
  • The linked manuals cover families. Optional HEPA filters, telescopic wands and powered tools are not assumed included. Conflicting electrical, capacity and template specifications are excluded.

Questions shoppers ask

Should I rely on “no maintenance costs” or “no filters required”?

No. Those WhirlWind marketing phrases are not a filter-care exemption: its guide requires the sponge filter to be installed, washed and fully dried. Avoiding replacement dustbags is the supported benefit; zero ownership cost is not.

What if I want bags and automatic rewind?

Neither configuration offers that combination. Decide which preference you can compromise on, or compare a different bagged model that documents rewind.

Methodology and sources

Compared disposal, retained filter care and cord storage. Retained manual copies were reviewed where fresh manual retrieval failed.
