The Electrolux UltraFlex ZUF4301OR is a bagless vacuum, but the available documentation is not enough to give it a reliable cleaning-performance verdict or rank it against newer models. What it does establish is useful for owners: filter references, model-specific parts listings and the need to match replacement parts to the appliance’s PNC. Check that number on the rating plate before buying a filter or accessory.
What this review can—and cannot—tell you
Electrolux’s parts catalogs and UltraFlex instruction-book material identify the ZUF4301OR and help with maintenance and part lookup. They do not provide a full model-specific specification sheet, independent cleaning tests, or a confirmed list of everything included in every version’s box. That means there is not enough evidence to judge its pickup on different floors, handling, noise, durability or value against other vacuums.
Appliances Online Australia describes the ZUF4301OR as a bagless UltraFlex vacuum and says its sealed filtration system and HEPA filter capture up to 99.99% of dust particles. That figure is a retailer claim; it is not an independently verified test result, and the listing does not state a year for the claim. Appliances Online Australia’s ZUF4301OR listing

Electrolux Australia’s fact sheet for the PC91-4IG names the ZUF4301OR as the model it replaces. This is a successor relationship stated for the Australian market, not proof that the models are identical or that their parts are interchangeable in every region.

Which filters are listed for the ZUF4301OR?
EF129 fine-dust filter
Electrolux’s German parts listing identifies an EF129 fine-dust filter for UltraFlex, and a ZUF4301OR-linked instruction-book listing names EF129 as the fine-dust-filter reference. It is the clearest documented filter reference for this model. Confirm your appliance’s PNC before ordering: the catalog shows multiple ZUF4301OR variants, so the model name alone may not be enough to match a part.

HEPA references EFH12W and EFH13W
The shared UltraFlex instruction book also names HEPA filter references EFH12W and EFH13W. Because that manual covers several UltraFlex variants, those references should not be treated as universally compatible with every ZUF4301OR. Check the PNC against Electrolux’s parts information before buying. The manual also cautions that “Accessories may vary from model to model.” UltraFlex instruction book and filter references

Find the exact model and PNC before ordering
Electrolux’s Italian catalog lists ZUF4301OR with PNCs 90027399401 and 90027396900. A separate catalog entry for “ZUF4301OR VACUUM” lists PNC 90027399400. These distinct entries are why it is safer to identify the rating-plate number than to rely on the model name alone when selecting a filter, nozzle or other replacement part.

A compatibility document hosted by OTTO includes ZUF4301OR among models associated with ZE357. Treat that as a starting point for checking, not definitive proof that the accessory fits your exact unit: confirm the part identity and PNC compatibility before purchase.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Should you buy a ZUF4301OR?
The documentation makes this model easier to identify and maintain than an appliance with no accessible parts or manual references. But it does not establish current price, condition, cleaning performance, included accessories or long-term reliability. If you are considering a used or remaining-stock unit, base the decision on the specific appliance’s condition and price, confirm that its PNC is legible, and check that the required filters and parts are available for that variant. Without model-specific comparative test evidence, a stronger recommendation would be guesswork.
