A washing machine with an impeller uses less motion and water than a washer with an agitator. Designed so laundry has more room to move, it drives clothes from the outer rim of the wash basket to the center, using a small amount of water to optimize the friction. This is what helps deliver a gentle, yet thorough clean.
The bad news is the gentle washing motion of an impeller isn't always as effective at cleaning tough stains as well as an agitator. At the same time, more robust materials are harder to clean. And while you conserve water inside an impeller washer, non-agitator washers typically take longer for a cycle to complete.
Because a hard piece of plastic isn't potentially roughing up clothes, the washing action in an impeller is far gentler, which means your clothes will likely last longer. Without the agitator in the middle, you also get more room in the drum, which means you can fit bulkier items like duvets without a problem.
The cons of a washer with an agitator include:
Items could get stuck on the agitator and tear. More room in the basket for bulky loading/unloading. Because there is an agitator column, these washers may offer less room than impeller washers. This makes washing bulky items like blankets and pillows more difficult.
Although, the agitator helps in general with getting better wash action. Your clothes will be more clean from this versus a washer without an agitator. Delicate items are better washed in a non agitator machine since this will give you less wear and tear on clothes.
And, as it turns out, using an impeller washer can increase the odds of this happening. Because impeller washers use less water and high speeds, creating currents to rub the clothes against each other, it's not surprising that clothing can become knotted in the process.
An Agitator is a machine used in a tank for mixing various process media together. Media include all liquid types, gases & solids (such as salts, powders, granules etc). In summary, it works by rotating an impeller to impart energy to the media which interact and mix.
The impeller can be easily damaged - Since the impeller is made of rubber that bends inside the casing, the chances of wear and tear are higher. Moreover, constant wear will cause the impeller to shed rubber, leading to the presence of rubber in the fluid.
At a minimum, you should replace your impeller according to your manual – for example, every 200 hours. Over time, the vanes become rigid and work less effectively, and you may see your engine overheating.
Top-loaders tend to last longer than front-loaders. This type of washer uses less water and has faster spinning speeds, making it a more efficient model. That's why you can expect top-load washers to last up to 14 years, while front-load washers may only last 10 years.
Impellers are low-profile cones or discs that spin and rotate to rub clothes against each other to get them clean. They also use less motion and water than a washer with an agitator.
Comforters: Instead of lugging your king-size comforter to a laundromat, you can wash it in any washer with a claimed capacity of at least 4.5 cubic feet, according to our tests. It's best washed by itself, for better agitation and rinsing.
A closed impeller is the most efficient form and is ideal for handling clean liquids with low viscosity. Consisting of two plates (known as shrouds) either side of the impeller vanes and a boss, extending from the front shroud into the pump suction to guide the liquid into the impeller eye.

Adding Pods to Washing Machines
Laundry detergent pods work best in standard top load washers and high-efficiency top-loading and front-loading washers. Washers with automatic detergent or fabric softener dispensers don't mix well with pods. Therefore, never place pods in dispenser drawers, only in the drum.
Generally if your machine is half full, you have a medium load. A large load fills it up until three-quarters full, and anything above that is considered extra large.
To properly wash a queen-size comforter, you'll need a high-efficiency washing machine (no agitator) with 3.5 cubic feet or more, depending on its fluffy factor (it should fit snugly but without cramming). Jumping up to 5.2 cubic feet will let you wash a king-size comforter and the sheet set all in one load.
King-size comforters typically measure 86 to 88 inches in length and 102 inches in width, making them too bulky to fit in many standard washers. Though, your washing machine should be large enough to properly clean a king-size comforter if its inner tub has a volume of at least 4.5 cubic feet.
At home, pods may have a small advantage in some households where overdosing on liquid or powder detergent is a common problem. It may be cheaper in the long run to use pods that are already measured out to avoid overdosing on other types of detergent. Lightweight to carry or ship and require very small storage space.
