You're standing in the appliance aisle, staring at two massive metal drums. One has a giant plastic post sticking up in the middle—that's the agitator. The other is just an empty, gaping hole. It looks like a giant bowl. That's a washer machine without agitator, also known as a high-efficiency (HE) top loader with an impeller.
It's a weirdly divisive topic in the world of home maintenance.
Some people swear by the old-school scrubbing power of the central post. Others think it’s a relic of the past that just ruins your favorite t-shirts. Honestly, making the switch isn't just about aesthetics or getting a bigger drum. It’s a completely different way of cleaning clothes. If you’ve spent your whole life using a machine that thrashes clothes around a central pole, switching to an impeller model can feel like a gamble. You might wonder: is this thing even washing anything?
The short answer is yes. But the long answer involves a bit of physics and a change in how you do laundry.
How a Washer Machine Without Agitator Actually Functions
Standard top loaders use that center post to twist and pull fabrics. It’s aggressive. It’s loud. It works by "mechanical action." In contrast, a washer machine without agitator uses a small, low-profile disc at the bottom called an impeller. Instead of grabbing the clothes, the impeller spins and creates a turbulent current in the water.
Think of it like a whirlpool.
The clothes rub against each other rather than rubbing against a plastic pole. This is what experts call "wash action." It’s a lot gentler. Because there is no giant pillar in the middle, you suddenly have a massive amount of room. You can fit a king-sized comforter in there without feeling like you're performing a wrestling move.
But there’s a catch.
Because the machine relies on the clothes interacting with one another, you can't just toss a huge pile of jeans on one side. Balance is everything. If the load is off-center, the machine will start "walking" across your laundry room floor during the spin cycle. It sounds like a helicopter is landing in your house.
The Energy Efficiency Paradox
Most people buy these machines because they want to save money on their utility bills. A washer machine without agitator is almost always HE-certified. It uses significantly less water. Instead of filling the entire drum to the top, it uses just enough to saturate the load.

According to the Department of Energy, HE top loaders can use about 15 to 20 gallons of water per load, whereas an old-school agitator model might gulp down 40 gallons. That’s a massive difference over the course of a year.
However, "less water" means you have to be careful about your detergent. If you use too much, or if you don't use the HE-specific stuff, you'll end up with a sudsy mess that never fully rinses out. Your clothes will feel crunchy. Or worse, the excess soap will build up in the outer drum and start to smell like a damp basement.
It’s also worth noting that because these machines use less water and a gentler motion, the cycle times are longer. You aren't getting a 30-minute wash anymore. You’re looking at 55 to 75 minutes for a standard load. That's the trade-off for the energy savings.
Why Some People Hate Them (And Why They're Wrong)
If you read reviews on sites like Lowe’s or Best Buy, you’ll see people complaining that their washer machine without agitator doesn't get their clothes clean. "The clothes on top didn't even get wet!" is a common one.
Usually, this is a user error.

These machines require a specific loading technique. You have to "donut" the clothes around the edges of the impeller, even though there's no pole there. If you just dump a mountain of laundry in the center, the machine can't move the fabric effectively. The stuff on top stays on top.
Another factor is the lack of "scrubbing." If you’re a mechanic or someone who works in deep mud, a washer machine without agitator might actually struggle. It doesn't have that "brute force" friction. For the average office worker or parent of toddlers, though, the impeller is more than enough. It actually extends the life of your clothes because it isn't stretching the fibers out every time you wash them.
Real-World Reliability Concerns
Reliability is the elephant in the room. Brands like Whirlpool, LG, and Samsung have dominated the impeller market. While the lack of an agitator means one less "big" plastic part to snap, these machines are packed with sensors.
They have to "sense" the load size to determine water levels. If those sensors go haywire, the machine is useless.
In my experience, and based on feedback from appliance repair technicians like those at Yale Appliance, impeller models tend to have more "unbalanced load" errors than traditional ones. If you aren't patient with how you load it, you'll be resetting that machine constantly.
Which One Should You Actually Buy?
It depends on your lifestyle.
- Buy a washer machine without agitator if: You wash a lot of bulky bedding, you care about water conservation, and you have expensive clothes you want to keep in good condition for years.
- Stick with an agitator if: You do extremely dirty manual labor, you want the fastest possible wash cycles, and you don't want to think about how you "arrange" your clothes in the drum.
Speed Queen is one of the few brands that still makes a high-quality agitator machine that people obsess over. But for most modern families, the extra capacity of an impeller model wins out. Being able to wash two weeks' worth of towels in one go is a game-changer for a busy household.
Maintenance is Non-Negotiable
You can't just ignore these machines. Because they use less water, they are prone to mold growth if you keep the lid closed between washes.
- Leave the lid open after every single cycle. Seriously.
- Run a "Clean Washer" cycle with a tablet like Affresh once a month.
- Don't overdo the fabric softener. Softener is basically liquid wax; it coats the sensors and creates a breeding ground for bacteria in low-water environments.
Final Steps for Your Next Purchase
Before you pull the trigger on a new washer, go to the store and reach into the bottom of the drum. If you’re short, you might actually have trouble reaching the bottom of a high-capacity impeller machine because the drums are so deep.
Measure your laundry room twice.
Check if your local utility company offers a rebate for switching to an HE washer machine without agitator. Many cities will literally give you $50 to $100 back for making the switch because it saves so much municipal water.
Once you get it home, read the manual. I know, nobody does that. But with an impeller, the way you load the machine is 90% of the battle. Treat it like a donut, keep the soap levels low, and you'll probably never go back to a central agitator again. You’ll save money, your clothes will look newer, and you’ll finally be able to wash that king-size duvet at home instead of trekking to the laundromat.
