NEFF N90 Built-In Compact Oven with Microwave Function and EcoClean
This N90 compact combi pairs 21 heating methods and a 900 W inverter microwave with an EcoClean self-cleaning back panel, all behind a 4.1-inch touch display.
The C24MS31G0B is a Graphite-Grey N90 compact oven with a built-in 900 W microwave, offering the same 21 heating methods as its pyrolytic siblings, CircoTherm and Air Fry included. It suits cooks who want top-range cooking ability in a 45 cm niche with sensible, low-effort cleaning.
Combination cooking is where it shines day to day. Microwave power runs alongside CircoTherm, the grills or hot air grilling, so a shepherd's pie heats through at microwave pace while the top browns under real oven heat. Inverter Technology keeps that microwave power smooth, even and kind to delicate food.
Ideal For
From CircoTherm baking to pizza settings to 900 W reheating, one compact appliance covers the whole weekly repertoire without a separate microwave on the counter.
The EcoClean Direct back panel continuously deals with grease at the rear of the cavity, while EasyClean softens the rest for a quick wipe.
Home Connect brings app control, the Oven Assistant and voice commands, so the oven fits into a connected kitchen from day one.
Key Features
CircoTherm, Air Fry, bread baking, pizza setting, low temperature cooking and the grills sit alongside microwave and combination modes.
A specially coated back panel breaks down grease during normal cooking, reducing how often the cavity needs proper attention.
Five power settings delivered gradually for even results, regulated to 600 W in longer sessions to protect delicate dishes.
A clear, high-resolution touchscreen with intuitive menus puts 21 methods and precise temperatures within easy reach.
App control, remote monitoring, the Oven Assistant and voice compatibility come as standard once connected to your home network.
Shorter preheating gets the cavity to temperature quickly, useful on evenings when dinner cannot wait for the oven.
N90 cooking without the N90 price tag
This model shares its cooking DNA with NEFF's most expensive compacts: the same 45-litre cavity, the same 21 heating methods, the same 30 to 275 degree range and the same 900 W inverter microwave. What you trade away is pyrolytic cleaning and the larger display, not cooking ability. CircoTherm still bakes evenly across shelves, Air Fry still crisps with the included tray, and combination modes still halve the wait for a weeknight dinner.
Cleaning that happens while you cook
EcoClean Direct takes a different approach from pyrolytic systems. The back panel of the cavity carries a ceramic coating that absorbs and breaks down grease during ordinary cooking, so the dirtiest surface in the oven maintains itself. For everything else there is EasyClean, which softens residue with heat and water so a cloth can finish the job in minutes. No dedicated cleaning cycle to schedule, no waiting for a locked door to cool.
One appliance for the whole evening
Consider a normal Tuesday. Rapid heat brings the oven to temperature while you assemble dinner, CircoTherm cooks it evenly, and the microwave combination shortens the wait. A pizza setting rescues the night when plans collapse, and dough proving quietly gets the weekend's bread started. Home Connect lets you check progress from the sofa, the SoftClose door forgives a hip-check when your hands are full, and the control panel lock keeps small children out of mischief. It is a compact oven built around how kitchens actually run.
How It Compares
| Kitchen Need | NEFF Technology | Practical Benefit |
|---|---|---|
| Weeknight dinners | Microwave combination modes | Microwave pace plus CircoTherm or grill browning delivers cooked-through, properly coloured food in less time. |
| Ongoing cleaning | EcoClean Direct back panel | The coated rear panel deals with grease during normal cooking, cutting routine cleaning effort noticeably. |
| Impatient evenings | Rapid heat function | Faster preheating means the oven is ready when you are, not ten minutes later. |
| Weekend baking | CircoTherm and bread settings | Even hot-air circulation and dedicated bread baking programmes give consistent results shelf after shelf. |
| Crisp textures | Air Fry with included tray | Chips, wings and vegetables crisp in the oven cavity without a countertop air fryer. |
| Connected kitchens | Home Connect Wi-Fi | App control, remote monitoring and voice commands integrate the oven into a smart home. |

The Verdict
Strengths
- 21 heating methods including CircoTherm and Air Fry
- EcoClean Direct self-cleaning back panel
- 900 W microwave with Inverter Technology
- 4.1-inch Full Touch TFT display
- Home Connect app and voice control
- Rapid heat for shorter preheating
- SoftClose drop-down door with CoolTouch glazing
Considerations
- EcoClean covers the back panel only; the rest of the cavity relies on the EasyClean programme and manual wiping, not pyrolytic cleaning.
- A hardwired 3.6 kW, 16 A connection is required, so budget for installation by a qualified electrician.
- As a 45-litre compact it handles everyday cooking comfortably, but the largest roasting trays belong in a full-size oven.
