Residential clothes washers compared on official ENERGY STAR certified ratings. Integrated Modified Energy Factor (IMEF) is the official energy-efficiency metric; a higher IMEF is better. Certified volume is the official tub size in cubic feet. Annual energy use is the certified kilowatt-hours per year. Integrated Water Factor (IWF) is the official water-efficiency metric; a lower IWF is better. Front-load and top-load models share these certified fields, so they appear in one table, and the official load configuration is printed on every card. A percent-better figure versus the federal IMEF standard is shown as a computed value labelled computed when both official figures exist.

Buying guide: how to choose the right clothes washer
IMEF and IWF are the official efficiency metrics
ENERGY STAR certifies clothes washers on Integrated Modified Energy Factor and Integrated Water Factor, plus annual energy use and annual water use. IMEF is higher-better. IWF is lower-better. We score the official IMEF, volume, annual energy use and IWF. When the official federal-standard IMEF is also published, we show how far the model's IMEF sits above that standard as a computed figure labelled computed. We do not use brochure energy-saver cycle claims in place of those official fields.
Front-load and top-load stay in one table, with the official configuration shown
Both load configurations share the same certified fields, so they can be compared on the same score. The official load configuration is printed on every card. A larger official volume is not automatically the right washer for a narrow closet. Match width and configuration to the space, then use the official IMEF, IWF and energy figures to compare models.
Identical official ratings are consolidated
Finish suffixes and sister-brand listings sometimes share the same official IMEF, volume, energy use, IWF and dimensions. We keep one product page for each identical rating set and list related official records in the details.
Safety and installation
Level the washer so it does not walk, and use the inlet hoses and electrical connection the maker specifies to reduce leak and shock risk. Do not wash items labeled as flammable or solvent-soaked. Keep children and pets away from an open door or lid, and use the child lock if the maker provides one. This is not a substitute for the product manual.
How this ranking is calculated
Score = weighted average of normalised specs, out of 10. Full method
Integrated Modified Energy Factor (IMEF)Official ENERGY STAR Integrated Modified Energy Factor. A higher IMEF means more washing work per unit of energy. Missing values take the category minimum. Scale: 2.06 → 3.1.
28%
Certified volumeOfficial ENERGY STAR certified tub volume in cubic feet. A larger tub is not automatically the right washer for a tight laundry closet. Missing values take the category minimum. Scale: 2.2 → 5.5 cu ft.
24%
Annual energy useOfficial ENERGY STAR annual energy use in kilowatt-hours per year. Lower is better. Missing values take the category minimum (the highest energy use in the set). Scale: 250 → 60 kWh/year.
24%
Integrated Water Factor (IWF)Official ENERGY STAR Integrated Water Factor. A lower IWF means less water per cubic foot of laundry. Missing values take the category minimum (the highest IWF in the set). Scale: 4.3 → 2.7.
Why are front-load and top-load washers in the same ranking?
They share the same official ENERGY STAR fields, and the official load configuration is printed on each card. Volume is a scored criterion, so a compact front-loader does not automatically outrank a large top-loader on size. If you only want one configuration, use the official load-configuration column rather than treating the overall score as a single shopping list.
Why is IMEF missing on some product pages?
A small number of official ENERGY STAR washer records in the dataset we used (retrieved November 13, 2026) leave Integrated Modified Energy Factor blank. We show Not listed and score that criterion at the category minimum, so a missing IMEF never outranks a published one.
Did you test these washers or list prices?
No. CyclePick ranks official ENERGY STAR certified ratings only. We do not test units, and we do not show prices or customer ratings.
Why do noise, warranty, spin speed and cycle time say Not listed?
Those figures are not in the ENERGY STAR certified-product fields we used, or they were blank on the record. We did not fetch a maker product page for these models in this pass, so we leave those extras as Not listed rather than copying them from a retailer listing. Additional washer features are shown when ENERGY STAR publishes them.
What does the computed IMEF percent-above-standard figure mean?
When ENERGY STAR publishes both the model's IMEF and the U.S. federal standard IMEF, we calculate (official IMEF minus official federal standard IMEF) divided by official federal standard IMEF and label that figure computed. It is not a separate certified field.
