There’s a certain kind of peace that comes from using an appliance that simply behaves—no loud slams, no wild temperature swings, no uneven reheating that ruins leftovers. That’s exactly the feeling I went chasing when I tested the Breville Smooth Wave and the Breville Compact Wave side by side.
Both look polished and premium, both promise smooth performance, and both come with Breville’s signature subtlety—quiet operation, soft-close doors, and thoughtful shortcut menus. But once I started using them daily, their personalities became very different.
Let me walk you through the differences so you can choose the one that actually fits your lifestyle instead of just looking good on your countertop.
Main Difference Between Breville Smooth Wave vs Compact Wave
The Breville Smooth Wave is a more powerful, larger, more advanced microwave with Sensor iQ, Power Smoothing Inverter, and 15 smart presets, ideal for serious cooking and precise reheating.
The Compact Wave is a smaller, simpler, lower-wattage microwave designed for quick reheating, basic cooking, and small kitchens where space is limited.

Detailed Comparative Review (My Experience)
-
Design & Build Quality
Both microwaves carry the classic Breville aesthetic—clean stainless steel faces, rounded edges, soft tones, and that satisfying soft-close door. But the moment I placed them side by side, the Smooth Wave immediately appeared more premium.
Breville Smooth Wave
The Smooth Wave feels larger, sturdier, and honestly more “serious.”
The stainless steel body has a heavier presence, and the control panel layout shows that it’s built for someone who cooks more than just popcorn.
Breville Compact Wave
The Compact Wave is noticeably lighter and smaller.
If your counter space is tight or you live in a studio apartment, this is definitely the easier fit. The design still feels polished, but not as weighty or premium as the Smooth Wave.
My takeaway:
If design presence matters, the Smooth Wave has that luxury edge. The Compact Wave prioritizes convenience and small footprint.

Ease of Use
Both are extremely beginner-friendly, but the Smooth Wave adds a layer of intelligence that I found immediately useful.
Smooth Wave – A Very Smart Microwave
Sensor iQ is something I didn’t know I needed until I used it.
Reheating pizza? It detects steam, adjusts power, and stops exactly at the right moment.
Defrosting chicken? It doesn’t cook the edges into rubber.
The “A Bit More” button is a heaven-sent feature. I used it nonstop.
Compact Wave – Simple & Quick
The Compact Wave keeps everything straightforward.
One-touch buttons for:
- Popcorn
- Beverage
- Pizza reheat
- Defrost
- Cook potatoes
It doesn’t sense or adjust automatically — you simply choose the common presets and go.
My takeaway:
If you want intelligent, hands-free cooking, the Smooth Wave is unbeatable.
If you want simple reheating and everyday use, the Compact Wave is easier.

Cooking Performance
This is where the gap between these two models becomes the most obvious.
Smooth Wave – Precise & Even Cooking
1250 watts + inverter technology makes a massive difference.
I tested:
- Lasagna
- Chicken thighs
- Leftover rice
- Frozen meals
- Oatmeal
- Chocolate melting
Every single thing came out evenly heated without the “hot edges, cold center” issue I always expect from microwaves.
The inverter tech doesn’t pulse power — it delivers smooth, steady heating, and the results show.
Compact Wave – Reliable but Not as Powerful
With 900 watts, it’s slower.
It reheats well but sometimes needs an extra 20–30 seconds.
Frozen meals come out fine, but not as evenly heated as the Smooth Wave.
My takeaway:
If fast, even heating matters, the Smooth Wave wins by a long shot.

Cleaning
Both have smooth interiors and easy wipe-down surfaces.
Smooth Wave’s larger interior made it easier to clean when reheating splatter-heavy foods like curries.
Compact Wave’s smaller size means cleaning is quicker because there’s simply less space.
