Agitator vs. impeller washers is a hot debate when it comes to choosing from one of the best top load washers or deciding to opt for one of the best front load washers instead. 

But before we get into it, it’s worth knowing exactly what we mean by agitator vs. impeller washers. An agitator is normally found in top load washing machines, however, some top loaders are made without agitators now too. 

Agitators are central columns that are positioned in the top load washer drum where you place your clothes. The agitator twists or moves in a rocking motion to rub against your dirty clothing, helping to lift off dirt and make your laundry clean again. 

An impeller, however, is normally disc-shaped and works by spinning the clothes and water around in a washing machine. Since there’s no agitator, clothes are cleaned in this way by rubbing against each other while they’re in the drum. 

Front load washers are fitted with an impeller rather than an agitator but which is better? And what are the pros and cons of impeller and agitator washers? Here, we’ll find out. You can also take a look at this year’s Black Friday washing machine deals for some great savings.  

Agitator vs. Impeller: Which washes better?  

Washing machines with an impeller tend to wash your clothes better than with an agitator. That means that, generally speaking, front load washers or top load washers without an agitator will do a better job at getting rid of tough stains and dirt off your clothes. 

Why? Well, when an impeller works it turns the clothes inside a washing machine in circles so that they are constantly spinning and using friction to rub the clothes against each other to get them clean. Agitator washers rely on just the agitator itself to do the cleaning and the clothes need to come into contact with the agitator to really be cleaned thoroughly. For stains and really dirty clothes, an impeller washer is the better option. 

Another thing to consider about washing machines with agitators is the potential damage to your clothes. Top load washers are known to cause damage over time to your clothes due to how rough the agitator is with fabrics.

Agitator vs. Impeller: Which is more energy efficient? 

When you use a washing machine with an agitator, such as a top loading washer, your clothes will be completely submerged in water while they are being cleaned. This makes agitator washers less efficient than washing machines with an impeller because they use more water. Washers with an impeller use less water because the clothes and water are spun around in circles, so the clothes are never fully submerged in a vat of water. Because there is less water used in impeller washers, you also won’t need as much detergent. 

There’s another reason why washing machines with an impeller are more energy-efficient than those with an agitator too. Impeller washers spin clothes at impressively high speeds which means that the clothes aren’t as wet when you take them out of the washer. What that means is that even if you’ve got one of the best dryers, your clothes won’t take as long to dry as they would when washed in an agitator washing machine. 

Top load washers are still very popular though and they are nearly always cheaper than a front load washer. Due to their popularity, top load washers have come a long way and you can now get high-efficiency top loaders which feature high spin speeds and an impeller inside the drum too. However, these types of washers still don’t get your clothes quite as clean as a front load washer due to the lack of gravity making the clothes tumble around more. 

With any type of washing machine, it’s often more eco-friendly to wash at lower temperatures, however, higher temperatures are needed to completely kill off bacteria and sanitize your washing machine, as well at tackling detergent build-up regularly.

Can you replace a washer agitator?  

In short, the answer is yes. If you’ve bought a washing machine, it’s pretty likely that you’ll want it to last as long as possible so maintaining all of the parts in your washing machine will help with that. 

First though, you might be wondering how to tell if your agitator is broken. Aside from obvious things like visibly noticing that the washing machine agitator has snapped or is broken, telltale signs that something is wrong include your washer becoming unusually loud when it’s on. 

If your agitator is broken, they can be replaced fairly easily, however, we’d always recommend getting a professional to run diagnostics on the washer first as the issue could be concerned with something separate such as the washer lid. 

Do top load washers have filters?

Some top load washers do have filters that will need regular cleaning to stop your washing machine from smelling. Front load washers will not need cleaning in the same way, but there are simple steps you’ll need to take to keep it in top condition including using a hot wash regularly and leaving the washer door open to prevent smells.
