Microwaves are no longer just about reheating leftovers—they’ve evolved into smart appliances capable of precise cooking, defrosting, and reheating. Breville offers two standout models: the Smooth Wave BMO850BSS and the Compact Wave BMO650SIL. Having tested both extensively, I can confidently share my experience on how they compare in design, usability, cooking performance, and overall convenience for a modern kitchen.
Key Difference Between Breville Smooth Wave vs Compact Wave Microwave Oven
While both Breville microwaves feature Sensor iQ technology and soft-close doors, the Smooth Wave delivers higher power (1250W) and a larger 1.2 cu.ft capacity, making it ideal for families or larger dishes. On the other hand, the Compact Wave is a 900W microwave with a 0.9 cu.ft capacity, perfect for smaller kitchens or single households. The Smooth Wave also offers 15 smart presets compared to the Compact Wave’s basic shortcut menu, giving it a slight edge in precision and versatility.

Detailed Comparative Review
Both microwaves feel thoughtfully designed, but their performance and features cater to slightly different users.
Design & Build Quality
The Smooth Wave stands out with its brushed stainless steel exterior, which gives it a professional and premium feel. It is slightly larger, making it ideal for families or those who cook larger meals. The Compact Wave, while smaller, has a sleek silver-painted exterior that works perfectly in limited spaces. Its lightweight design makes it easy to move if needed. Both models include soft-close doors that are noticeably quieter, a subtle but satisfying feature that improves the overall kitchen experience.
Ease of Use
Using both models is straightforward. The Smooth Wave comes with a touchscreen and easy shortcuts, including Smart Cook, Smart Reheat, and Smart Defrost, which automatically detect food steam and adjust cooking time. The Compact Wave also offers one-touch shortcuts for reheating and defrosting, but the fewer preset options make it slightly less versatile. I appreciated the “A Bit More” feature on the Smooth Wave, which allows me to extend cooking without restarting the cycle—very handy for reheating unevenly cooked leftovers.

Cooking Performance
The Smooth Wave excels at even cooking, thanks to Power Smoothing Inverter technology. Foods like pizza, lasagna, and frozen meals heat evenly without hot spots or overcooked edges. The Compact Wave also cooks well but is limited by its 900W output. Small meals, popcorn, and reheating work perfectly, but larger dishes require more attention. Both microwaves deliver Turbo Defrost that efficiently thaws meat and frozen meals without drying them out.
Functions & Features
- Smooth Wave: 15 smart presets, Smart Cook, Smart Defrost, Smart Reheat, A Bit More, Child Lock, +30 Sec Instant Start, Turntable Off, Shortcuts Panel
- Compact Wave: Shortcut buttons for Reheat, Defrost, Popcorn & Beverage, Food Menu presets (pizza, potatoes, vegetables), Child Lock, +30 Sec Instant Start, Soft Close Door
The Smooth Wave clearly offers more control and versatility for those who cook frequently or need precision, while the Compact Wave is designed for simplicity and convenience.
