Xiaomi Smart Air Fryer Pro 4L Review: 2026 Verdict

The Xiaomi Smart Air Fryer Pro 4L is a solid entry-level smart air fryer for 1 to 3 people: compact, with a viewing window and controllable from the Xiaomi Home app, it mainly stands out for its low-temperature functions (40 to 80°C, or 105 to 175°F). Its limitations are clear: a 4 L (4.2 qt) basket, a 200°C (400°F) ceiling and less even heat than more powerful models, so you need to shake the food.

This review is based on Xiaomi’s published specifications, independent reviews from the specialist press and verified buyer feedback. We don’t present in-house measurements: our job is to cross-check these sources to help you decide. You can see every model we compare on our air fryers page.

Xiaomi Smart Air Fryer Pro 4L specifications

Launched in Europe in spring 2023, it’s still one of the most widespread small smart air fryers there in 2026, notably on Amazon and in Xiaomi’s own stores. Models and versions sold in Canada can differ from the European ones: check that the listing is for a 120 V North American model.

Strengths

A genuinely useful window

The Xiaomi Smart Air Fryer Pro’s first asset is its transparent, internally lit window. On a standard drawer air fryer, you have to pull the basket out to check progress, which drops the temperature. Here, a quick glance tells you whether the fries are golden or the vegetables are starting to char. Buyers regularly cite this detail as the main reason for their choice, and the specialist press praised it from launch.

Low-temperature functions that are rare at this level

The 40 to 80°C (105 to 175°F) range opens up uses you rarely see on a compact air fryer: gentle defrosting, proofing dough, homemade yogurt, drying fruit and keeping food warm without drying it out. It isn’t a dedicated dehydrator, and the small capacity limits quantities, but for apple chips or the occasional batch of yogurt, it’s a real bonus.

A complete app and simple controls

The Xiaomi Home app lets you start and monitor cooking remotely, adjust time or temperature, schedule a delayed start and browse more than 100 recipes suited to the 4 L format. Voice control works through Google Assistant. On the unit itself, the dial and OLED screen stay simple: turn, press, and a reminder tells you when to shake the basket. If you already own Xiaomi devices (robot vacuum, air purifier, bulbs), integration is seamless.

Compact size and a clean design

At about 25 cm (10 in.) wide and 3.9 kg, it’s easy to store and takes up little room on a narrow counter, in a studio apartment or in a rental kitchen. Its clean white design is a change from bulkier black air fryers.

Limitations

• Capacity built for small households: Xiaomi mentions use for up to 5 people, but owner reviews and independent reviews put comfortable use at 2 or 3 people. For crisp fries, don’t overload the basket.
• Less even heat: several reviews note that food in the centre browns more slowly than at the edges. Shaking or turning halfway through is necessary, as on most single-element air fryers of this size.
• 200°C (400°F) maximum: enough for fries, chicken or vegetables, but less suited to very fierce searing. Models such as the Cosori Lite go up to 230°C (450°F).
• Basket cleaning: according to published reviews, the basket is hand-wash only, and only the removable grill plate goes in the dishwasher. Check the manual for your version.
• An app with room to improve: functional and full of recipes, but considered less pleasant than Cosori’s or Philips’. Creating an account and pairing over Wi-Fi are the steps that raise the most questions among buyers.

What buyers and the press say

Verified buyer reviews agree on three positives: the viewing window, the compact size and a good balance between features and price positioning. Criticism focuses on basket size as the household grows, the need to shake food and the somewhat bare-bones app. The European tech press generally gave this model a warm reception, recommending it to couples and small households who want a smart air fryer without the bulk.

Who is it for?

• Yes if you cook for 1 to 3 people, are short on space, like to watch your food without opening the drawer or already use the Xiaomi Home ecosystem.
• No if you regularly feed 4 or more people, want to cook two dishes at once or are looking for the most even cooking with no intervention.

Alternatives worth considering

Cosori Lite 3.8L Air Fryer — the compact smart alternative

A very similar format (3.8 L or 4 qt, 1,500 W), but with a temperature that climbs to 230°C (450°F), a well-rated VeSync app and non-stick accessories that Cosori lists as dishwasher-safe. It has no window and no low-temperature functions. Choose it if you prioritize easy cleaning and a higher top temperature.

Philips Airfryer 3000 Series XL 6.2L — to move up a size

With 6.2 L (6.6 qt) and 2,000 W, this Philips is a better fit for households of 3 to 5 people. It offers plenty of programs and recipes through the Philips app, but it can’t be controlled remotely over Wi-Fi. It’s the logical choice if the Xiaomi feels too small.

Moulinex Easy Fry Max 5L — the no-frills classic

5 L (5.3 qt), 1,500 W and about 10 automatic programs: a simple, proven air fryer with no app. It suits you if connectivity doesn’t matter and you want a bit more room for a family of 3 or 4.

Cosori Dual Blaze 6.4L Smart Air Fryer — for more even cooking

Its dual heating element, above and below the basket, reduces the need to turn food, and it’s controlled through the VeSync app. Larger and more premium, it answers precisely the main criticism levelled at the Xiaomi.

Getting started

Setup is straightforward, but a few steps help you avoid unpleasant surprises. Remove all films and labels, wash the basket and grill plate in soapy water, then run the empty unit for a few minutes, as most manufacturers recommend, to get rid of the new-appliance smell. For the smart features, install the Xiaomi Home app, create or sign in to your Xiaomi account, select the server region that matches your unit’s market (Europe for the European version) and keep your phone close to the unit during Wi-Fi pairing. If pairing fails, check that your phone is on the same home network and reset the unit’s Wi-Fi as described in the manual. Once it’s paired, you can add it to Google Home for voice control.

Mistakes to avoid and usage tips

• Overloading the basket: in 4 L, a thin layer gives far better results. Two batches beat one soggy one.
• Forgetting to shake: follow the unit’s reminder and shake or turn the food halfway through.
• Skipping preheating: a few minutes of preheating clearly improves the crispness of fries and breaded food.
• Using metal utensils: they damage the non-stick coating. Use silicone or wood.
• Pushing it against the wall: leave clear space around the hot-air outlet, place it on a stable, heat-resistant surface and don’t run it under a low cabinet.
• Scheduling a delayed start with perishable food: remote scheduling is handy, but avoid leaving raw meat or fish at room temperature for hours.

Our verdict

In 2026, the Xiaomi Smart Air Fryer Pro 4L is still a sensible choice for a couple, a student or a small household that wants a smart, compact and versatile air fryer. Its lit window and low-temperature functions set it apart from most rivals of the same size. You do, however, have to accept limited capacity, less even heat and a hand-wash basket. If you cook for more than three people, look at the Philips 3000 Series XL or the Cosori Dual Blaze instead; if you want a small smart model that’s easier to clean, consider the Cosori Lite 3.8L.
