Quick verdict: Xiaomi’s MAF02 is a compact 3.5 L smart air fryer with a useful 40–200°C range, 1,500 W heating, an OLED control knob and app-based recipes, scheduling and custom modes. It is a credible fit for one to three people who will use its low-temperature functions as well as ordinary air frying. The main trade-offs are the modest basket size, dependence on 2.4 GHz Wi-Fi for connected features and the need to confirm regional app compatibility when buying used.

Xiaomi MAF02 at a glance
| Item | Official detail | What it means |
|---|---|---|
| Model | MAF02 | Check this code on the rating label before buying parts or a used unit |
| Capacity | 3.5 L | Best suited to one to three people and smaller batches |
| Rated power | 1,500 W | Applies to most regions; Xiaomi lists 1,400 W for the Taiwan version |
| Temperature range | 40–200°C | Supports air frying plus low-temperature defrosting, fermenting and dehydrating |
| Controls | OLED display with turn-and-press knob | Core settings remain available on the appliance |
| Connectivity | 2.4 GHz Wi-Fi, Xiaomi Home/Mi Home app | Router, app region and firmware matter for smart features |
| Net weight | 3.9 kg | Relatively easy to move, but allow ventilation space while operating |
What the 3.5 L capacity is actually good for
Xiaomi describes the basket as suitable for one to three people. That is a more useful expectation than calling it a “family-size” fryer. A 3.5 L basket can handle snacks, vegetables, reheating, side dishes and modest portions of one food, but it is unlikely to cook a complete meal for several adults in one layer.
- Good fit: one-person meals, couples, small kitchens, chips or vegetables as a side and people who cook in several short batches.
- Possible with planning: meals for three when the protein and side are cooked separately or the included grill is used appropriately.
- Likely too small: large whole joints, broad baking dishes, meal preparation for a week or a full meal for a larger family.
Do not confuse litres with usable flat cooking area. Crowding food can slow browning and make turning more important. Our air-fryer size guide explains how basket shape and batch size affect real capacity.
Controls, app and Wi-Fi
The MAF02 is not app-only. Its OLED screen and rotary control let you set time and temperature on the fryer. The Xiaomi Home or Mi Home app adds smart recipes, custom cooking modes, scheduling and supported voice-control features.
The Wi-Fi radio uses the 2.4 GHz band. If setup fails, check that the phone and appliance are using a compatible 2.4 GHz network, Bluetooth and location permissions required by the app are available, the correct app region is selected and the fryer’s Wi-Fi has been reset through its settings. Availability of recipes, voice control and integrations can vary by region, language and firmware.
Used-buying warning: a seller showing that the fryer heats does not prove the smart functions will pair with your account or region. Ask for a reset demonstration and photograph of the MAF02 rating label.
What 40–200°C adds
Most basket air fryers focus on high-temperature cooking. Xiaomi pairs the MAF02’s 40–200°C range with two fan-speed bands. Xiaomi’s published examples include yoghurt at 40°C, defrosting at 45°C, dried fruit at 60°C and conventional air-frying or baking at higher temperatures.
| Use | Xiaomi example | Practical note |
|---|---|---|
| Fermenting | Yoghurt at 40°C | Low-temperature cycles can run for several hours |
| Defrosting | 45°C | Use only for food and timings appropriate to Xiaomi’s instructions |
| Dehydrating | Fruit at 60°C | Thin, evenly cut pieces improve consistency |
| Vegetables | 160°C | Turn or shake when the load is large |
| Chicken wings | 180°C | Cooking time depends on size, load and starting temperature |
| Potato wedges | 200°C | A small amount of oil can help fresh potatoes brown |
The advertised “up to 24 hours” applies to low-temperature operation. Higher temperatures have shorter permitted cooking times. Treat Xiaomi’s recipe temperatures as starting points, not guarantees: the company advises checking food and adjusting for its origin, size, shape and weight.
Preheating and checking food
Xiaomi says preheating is not strictly required, although it can improve baking results. Its support guidance suggests an empty 200°C preheat for about three to five minutes or using the app recipe’s preheat function. The basket switch pauses heating when the basket is removed; replacing it resumes the same program.
For larger or more numerous pieces, turn or shake the food during cooking. The fryer can issue a turn reminder when a program runs longer than eight minutes, except for dried-fruit operation. Always verify safe internal temperatures independently for meat and other high-risk foods.
Cleaning the MAF02 correctly
Disconnect the power and let the fryer cool before cleaning. Xiaomi says the basket, frying plate and grill are removable and may be cleaned in a dishwasher. The electrical body must never be immersed or placed in a dishwasher.
- Clean the coated basket after each use.
- Use a soft cloth or sponge with neutral detergent.
- Do not use steel wool, abrasive pads or metal tools that can damage the coating.
- Wipe the cavity rather than flooding it with water.
- Dry removable parts before reassembly and storage.
The four silicone feet on the frying plate keep it positioned and are intended to remain attached. For general technique, see our air-fryer cleaning guide; Xiaomi’s exact instructions take priority.
Buying a used Xiaomi MAF02
- Require a clear image of the rating label showing model MAF02, voltage and power.
- Check that the basket, frying plate and included grill are present and fit securely.
- Inspect the coating under bright light for deep scratches, peeling or exposed metal.
- Confirm the OLED display, knob, basket-pause switch and heating cycle operate normally.
- Have the seller remove the appliance from their Xiaomi account and reset Wi-Fi.
- Check that your country’s Xiaomi Home app region can discover the fryer before paying.
- Reject a unit with a damaged cable, loose handle, distorted basket or persistent electrical smell.
If the fryer behaves abnormally, Xiaomi advises stopping use immediately rather than disassembling or repairing it yourself. Our burning-smell guide explains general warning signs.
Pros and limitations
Reasons to consider it
- Useful 40–200°C range rather than high-temperature air frying alone.
- On-device controls plus optional app recipes and scheduling.
- Compact 3.5 L size with an included grill for flexible loading.
- Dishwasher-compatible removable basket, frying plate and grill according to Xiaomi’s support guidance.
Reasons to look elsewhere
- Too small for many family-size, single-batch meals.
- Smart features depend on 2.4 GHz Wi-Fi, the correct app region and supported services.
- Long low-temperature cycles are specialist functions, not extra basket capacity.
- No independent hands-on performance testing was conducted for this guide.
Verdict
The Xiaomi Mi Smart Air Fryer 3.5L MAF02 makes the most sense for a small household that values low-temperature cooking and connected recipes as much as ordinary air frying. Its physical controls mean the fryer remains useful without the app, while the 40–200°C range is genuinely broader than that of many basic compact models. Buyers who mainly want large, single-batch family meals should choose a larger basket instead.
