If you’re looking for the best top-load washer without an agitator, look for an impeller model: it uses a low-profile cone or disc instead of a fixed center post. Two current Whirlpool examples illustrate the choice: the WTW6150PB is listed as a 5.3-cu.-ft. impeller washer, while the WTW6157PW has a removable agitator and can be used with its impeller when the post is removed. Neither is established as a universal cleaning or reliability winner; the right fit depends on your space, laundry loads, preferred features and efficiency priorities.
What “without an agitator” means
In everyday shopping language, a top-load washer “without an agitator” usually means an impeller washer. Instead of a tall, fixed center post, an impeller machine has a low-profile cone or disc at the bottom of the tub. ENERGY STAR describes top-load impellers as a more energy- and water-efficient option than traditional top-load washers. ENERGY STAR’s clothes washer guidance
There are two configurations to distinguish: an impeller-only machine and a washer supplied with a removable agitator that can also be used with the impeller. If you want the open-tub design all the time, check that the specific model does not require a post to be installed.
Two Whirlpool options to compare
| Model | Configuration | Published capacity | What the distinction means |
|---|---|---|---|
| Whirlpool WTW6150PB | Impeller | 5.3 cu. ft., per Whirlpool’s comparison chart and 2025 lineup guide | A direct-fit choice for shoppers seeking an impeller washer without a removable-post configuration listed in the cited materials. Whirlpool comparison chart; Whirlpool 2025 lineup guide |
| Whirlpool WTW6157PW | Removable agitator; impeller option when the post is removed | 5.2–5.3 cu. ft., per Whirlpool’s product page | Offers a choice between using the removable post and having the impeller configuration. Whirlpool WTW6157PW product page |
These are examples documented by Whirlpool, not a head-to-head test ranking. The cited product information does not establish which cleans better, runs more quietly, lasts longer or offers the better value in your local market.

How impeller washing works—and what that does not prove
With an impeller’s low-profile wash plate rather than a central post, the machine moves the load through the wash action. LG describes its own top-load impeller mechanism this way: “Each LG Top Load Impeller washer uses a high efficiency impeller that rotates so clothes rub against each other to break down stains.” LG’s top-load washer information
That is a manufacturer description of how its washers work, not independent evidence that a particular impeller model cleans better, treats fabric more gently or outperforms a particular agitator washer. For those comparisons, look for testing of the exact models you are considering.

Compare efficiency with the exact model in mind
ENERGY STAR’s general guidance says full-sized ENERGY STAR certified washers use 14 gallons per load compared with 20 gallons for a standard machine. It also reports that certified front-load washers use about 50% less energy and water than top-load agitator washers, and front-load washers use about 25% less energy and water than top-load impeller washers. These are program-level comparisons, not measurements or guarantees for every model, household or wash cycle. ENERGY STAR clothes washer guidance
If reducing resource use is your main goal, compare front-loaders as well as top-load impellers. Before buying, check ENERGY STAR status for the exact model and consult its current EnergyGuide; a general category comparison cannot substitute for a model-specific estimate.

What to check before you buy
- Capacity and typical loads: Match the stated tub capacity to the amount and type of laundry your household usually washes. A larger capacity is useful only if it suits your actual loads.
- Space and access: Verify the washer’s full width, depth and height, plus lid clearance, doorway access and the route into the laundry area. A comparison chart’s width filter is not a substitute for the complete installation dimensions.
- Fixed versus removable post: Decide whether you want an impeller-only machine or the option to install a removable agitator. Confirm what comes with the exact model and how its configuration works.
- Controls and cycles: Compare control type and available cycles against the way you do laundry. Whirlpool’s comparison chart distinguishes models by capacity, width, smart features, control type and washer configuration.
- Water-level or deeper-fill options: If you prefer more water for certain loads, check whether the exact washer offers a suitable setting and understand its operating instructions.
- Care and installation: Read the model’s care instructions and confirm local delivery, installation and haul-away terms with the retailer. Availability and service terms vary by location.
