Breville Combi Wave BMO870 Review (2026)
Breville Combi Wave BMO870 review: microwave, convection, and air fry in one 1.2 cu ft unit with Fast Combi roasting, soft-close door, and sensor programs.


Breville Combi Wave 3 in 1 BMO870
Microwave, convection oven, and air fryer in one premium unit.
Our verdict
The Combi Wave is the premium small kitchen solution: a strong sensor microwave that also roasts and air fries credibly, wrapped in the quietest, softest closing package here. You pay for versatility you must actually use to justify it.
What we like
- Element IQ and Fast Combi mode blend microwave and convection for faster roasts
- Air fry mode crisps in the same cavity
- Soft close door and quieter operation than most rivals
- Smart cook, reheat, and defrost programs use sensor logic
What to watch out for
- Premium tier cost
- Air fry capacity is smaller than a dedicated fryer oven
- Learning the dial and menu system takes time
Who it is for
Best for apartment and small home cooks without room for separate microwave, toaster oven, and air fryer, who cook varied meals for one to three people. Pure reheat households should save money with the Panasonic SN686S.
Microwave, combi, and air fry modes
As a microwave, it offers smart cook, reheat, and defrost with sensor logic and gentle power for foods like butter and chocolate. Fast Combi blends microwave speed with convection browning, so a chicken roasts faster with better skin than either mode alone.
Air fry mode handles fries, wings, and vegetables in the included pan. Capacity is snack and side sized, not family batch sized.
Controls and living with it
The dial plus screen interface is powerful and, owners agree, takes a week to learn. The soft close door and muted tones are daily pleasures no spec sheet conveys.
At 20.4 x 18.5 inches and 32 lb, it claims real counter territory, and the trivet and pan need a storage plan.
How it stacks up
Against the Panasonic NN-SN686S, the Breville matches 1.2 cubic foot microwave duty with slightly lower microwave wattage on paper, then adds convection and air fry the Panasonic lacks entirely. Against the Panasonic HomeChef NN-CD87KS, the Breville offers a more refined interface and soft close door, while the HomeChef adds broiling and inverter microwaving in an even larger body.
Choose the Combi Wave for polish and combi roasting; choose HomeChef for broil and inverter range.
Storage, cleanup, and the learning curve
Ownership space planning matters more here than with a microwave-only model. The Combi Wave is large and deep on the counter at 20.4 x 18.5 inches and 32 lb, and owners flag that the trivet and air fry pan need a storage plan of their own rather than living loose in a drawer.
Cleanup also widens beyond a microwave wipe down. Roasting and air frying leave more surfaces to clean after cooking, as the comparison with the Panasonic notes, and fatty foods need attention inside the cavity. Set against that, owners praise how the soft close door and quieter operation feel in daily use, and most accept the menu learning curve after the first week.
When the extra modes earn their counter space
The Combi Wave only justifies its premium tier and deeper footprint when the convection and air fry modes replace real work elsewhere. Households that roast a chicken, crisp fries, and reheat leftovers in the same week use all three systems as intended.
If those extra modes would sit idle, the owners who praise the soft close door and reheat quality are still buying a microwave, just a larger and more complex one than the job requires.

FAQ
Questions, answered straight
Can the Combi Wave replace a toaster oven?
For roasting, baking small items, and air frying, largely yes. Toast purists will still prefer a dedicated toaster or toaster oven for bread.
What is Fast Combi mode?
It combines microwave energy with convection heat to cook faster while still browning, useful for roasts and casseroles.
Does it need special cookware?
Microwave safe dishes for microwave modes, and the included or metal pans only for convection and air fry modes, per the manual.
