What’s the Difference and Which One is Right for You?
When shopping for a new top-load washing machine in Arizona, you’ll quickly face a choice between two main types of cleaning mechanisms: impeller washers and agitator (also known as propeller) washers. While both clean clothes effectively, they work in fundamentally different ways, each with its own advantages and disadvantages.
In this in-depth guide, we’ll break down how each system works, compare their performance, and help you decide which is the best fit for your laundry needs.

🌀 What is an Impeller Washer?
An impeller washer uses a low-profile cone or disc at the bottom of the drum to gently move clothes through water. It relies on water currents and friction between fabrics rather than a central agitator post.
✅ Pros of Impeller Washers:
- Gentler on clothes – No tall agitator means less wear and tear on fabrics.
- Higher efficiency – Uses less water and energy; many are HE (High Efficiency) certified.
- More capacity – The absence of an agitator leaves more space for bulky loads like comforters.
- Sleeker, modern design – Often paired with glass lids and electronic controls.
❌ Cons of Impeller Washers:
- Longer wash cycles – Cleaning can take more time compared to agitator models.
- May struggle with heavily soiled items – Doesn’t offer the same aggressive scrubbing action.
- Can cause tangling – Clothes sometimes wrap around the impeller.
⚙️ What is an Agitator (Propeller) Washer?
An agitator washer has a tall spindle in the center of the drum that twists back and forth to rub clothes together and dislodge dirt.
✅ Pros of Agitator Washers:
- Excellent for tough stains and dirt – Great for workwear, sports gear, and kid clothes.
- Faster wash times – Traditional models are quick and effective.
- Simple, proven design – Trusted by generations for its dependable performance.
❌ Cons of Agitator Washers:
- Harsher on clothes – The twisting action can wear out delicate fabrics faster.
- Smaller capacity – The agitator takes up space, making it harder to wash large loads.
- More water usage – Not as efficient as impeller models; some use up to 40% more water.
🔍 Side-by-Side Comparison:
| Feature | Impeller Washer | Agitator Washer |
|---|---|---|
| Cleaning Method | Water currents + fabric friction | Central post scrubbing motion |
| Fabric Care | Gentle on clothes | Harsher on delicate items |
| Capacity | Larger drum space | Less space due to agitator |
| Wash Speed | Slower wash cycles | Faster cycles |
| Soil Removal | Good for light/medium soil | Great for heavy soil/stains |
| Water & Energy Use | More efficient (HE) | Less efficient |
| Noise Level | Generally quieter | Often louder due to mechanical motion |
🏁 Final Thoughts: Which Washer is Right for You?
Choose an impeller washer if:
- You want to preserve fabric life
- You have larger loads or bedding
- You care about energy efficiency
Choose an agitator washer if:
- You often wash heavily soiled clothes
- You want shorter wash cycles
- You prefer a more traditional washer
Ultimately, both systems can clean effectively—it just depends on your household’s laundry needs. And when in doubt, reach out to a local pro.
