Microwaves aren’t just about reheating leftovers anymore. Over the past few years, I’ve noticed how brands like Breville have really changed the way we think about countertop microwaves. Two models that often get compared are the Breville Smooth Wave and the Breville Compact Wave. I’ve spent time using both, and while they share some DNA, they serve slightly different needs.
In this article, I’ll break down the key differences, put together a comparison table, and share my own hands-on thoughts on design, usability, and features. By the end, you’ll know exactly which model is the right fit for your kitchen.
Key Difference Between Breville Smooth Wave vs Compact Wave
The Breville Smooth Wave is the more advanced, feature-rich option designed for people who want precise cooking with Sensor iQ technology and higher wattage (1250W). It’s built for families or anyone who regularly uses a microwave for more than just reheating.
On the other hand, the Breville Compact Wave is a smaller, simpler version with 900W of power. It’s perfect for smaller kitchens, apartments, dorms, or anyone who mainly needs reheating and basic cooking functions without the bulk or the price tag.

Detailed Comparative Review

Design & Build Quality
The first thing I noticed when unboxing both microwaves was the look and feel. The Smooth Wave has a premium brushed stainless steel finish. It feels solid, modern, and more like a professional kitchen appliance. I found it slightly larger, but that extra size translates into more cooking space.
The Compact Wave, on the other hand, has a lighter, silver-painted metal housing. It doesn’t feel as luxurious but is still well-built. The real advantage here is the smaller footprint. I could easily place it on a tight countertop in a smaller kitchen, whereas the Smooth Wave required a dedicated space.
Verdict: If aesthetics and durability matter most, the Smooth Wave wins. If space-saving is your priority, the Compact Wave is the smarter choice.

Ease of Use
I personally found the Smooth Wave more intuitive thanks to its shortcuts panel on the inside door. Everyday tasks like melting butter, softening chocolate, or reheating pizza were literally one-touch. The “A Bit More” button became one of my favorites, it’s such a clever little feature for adding 30 seconds without restarting.
The Compact Wave keeps things straightforward. It has dedicated buttons for popcorn, beverage, defrost, and reheat. While not as advanced, it’s perfect for quick tasks. My parents, for example, prefer the Compact Wave because it’s less intimidating; no scrolling through 15 presets.
Verdict: Smooth Wave is better for those who like customization and smart features. Compact Wave is better for users who prefer simplicity.

Cooking & Heating Performance
Here’s where the differences became clear in my kitchen.
With the Smooth Wave, the Sensor iQ technology really impressed me. It adjusts power automatically depending on the food. When I reheated lasagna, it came out hot in the middle but not dried out on the edges (something that happens often with cheaper microwaves). The Power Smoothing Inverter also delivered more even results compared to the stop-start bursts you get in standard microwaves.
The Compact Wave performed well for basic tasks like reheating soup, defrosting veggies, or popping popcorn. But when I tried reheating denser foods, I noticed some unevenness, hot on the outside but still lukewarm inside. For light use, though, it’s perfectly fine.
Verdict: Smooth Wave is noticeably better for precision cooking. Compact Wave is fine for basic reheating.

Noise & Door Mechanism
Both models come with Breville’s soft-close door and sound suite, and honestly, this is one of the most underrated features. Traditional microwaves slam loudly, but both of these are whisper-quiet. I could heat food late at night without waking anyone up.
That said, the Smooth Wave is slightly quieter during operation compared to the Compact Wave. It’s not a huge difference, but I did notice it when running them side by side.
Verdict: Both are excellent in this department, but Smooth Wave edges out with slightly better noise control.

Conclusion: Which One Should You Buy?
After using both models, I’d say the decision really comes down to your lifestyle and kitchen setup.
If you cook frequently, want precision reheating, and value premium design, the Breville Smooth Wave is absolutely worth the investment. It feels like a step above a standard microwave and has genuinely useful smart features that make daily cooking easier.
But if you’re in a smaller space, mostly reheat leftovers, or want a microwave that’s simple and affordable, the Breville Compact Wave is the perfect fit. It doesn’t try to do everything, but it does the basics very well.
My recommendation:
- Go for the Smooth Wave if you want performance and advanced features.
- Choose the Compact Wave if you want something budget-friendly and space-saving.
Either way, Breville’s build quality and design touches like the soft-close door make both of these a cut above the average microwave.
