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 app control through Xiaomi Home, it stands out mainly for its low-temperature modes (105°F to 175°F, or 40°C to 80°C). Its downsides are clear: a 4.2-quart (4 L) basket, a 390°F (200°C) max and less even heat than more powerful models, so you have to shake the food.

This review draws on Xiaomi’s published specs, independent reviews from tech and appliance outlets, and verified owner feedback. We don’t present in-house measurements: our job is to cross-check these sources to help you decide. You’ll find every model we compare on our air fryers page.

Xiaomi Smart Air Fryer Pro 4L key specs

Launched in Europe in spring 2023, this model is still one of the most common small smart air fryers in 2026, notably on Amazon and through Xiaomi’s own stores.

Pros

A viewing window that earns its keep

The Xiaomi Smart Air Fryer Pro’s biggest selling point is its see-through window, lit from the inside. On a typical basket air fryer, you have to pull the basket out to check on your food, which drops the temperature. Here, a quick glance tells you whether the fries are golden or the vegetables are starting to char. Owners regularly cite this detail as the main reason they bought it, and reviewers praised it from launch.

Low-temperature modes that are rare in this class

The 105°F to 175°F (40°C to 80°C) 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’s not a dedicated dehydrator, and the small capacity limits batch size, but for apple chips or the occasional batch of yogurt, it’s a real bonus.

A full-featured 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 sized for the 4.2-quart basket. Voice control works through Google Assistant. On the unit itself, the dial and OLED screen keep things simple: turn, press, and a reminder tells you when to shake the basket. If you already own Xiaomi devices (a robot vacuum, an air purifier, smart bulbs), it slots right in.

Compact and clean-looking

At about 10 in (25 cm) wide and 8.6 lb (3.9 kg), it’s easy to store and takes up little room on a narrow countertop, in a studio apartment or in a rental kitchen. Its clean white design makes a nice change from bulkier black air fryers.

Cons

• Sized for small households: Xiaomi says it can serve up to 5 people, but owner feedback and independent reviews put the comfortable limit at 2 or 3. For crispy fries, don’t overload the basket.
• Less even heat: several reviews note that food in the center browns more slowly than food at the edges. You’ll need to shake or flip halfway through, as with most single-element air fryers this size.
• 390°F (200°C) max: enough for fries, chicken or vegetables, but not ideal for high-heat searing. Models such as the Cosori Lite go up to 445°F (230°C).
• Basket cleanup: according to published reviews, the basket is hand-wash only, and just the removable crisper plate goes in the dishwasher. Check the manual for your version.
• An app with room to improve: it works and has plenty of recipes, but reviewers find it less pleasant to use than Cosori’s or Philips’. Creating an account and pairing over Wi-Fi are the steps owners ask about most.

What owners and reviewers say

Verified owner reviews agree on three positives: the viewing window, the compact size and a good balance of features for its price tier. The complaints focus on basket size as a household grows, the need to shake food and an app that feels a bit bare-bones. 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 basket or already use the Xiaomi Home ecosystem.
• No if you regularly feed 4 or more people, want to cook two dishes at once or want the most even cooking possible without having to step in.

Alternatives worth considering

Cosori Lite 3.8L Air Fryer — the compact smart alternative

A very similar size (4 qt, or 3.8 L, and 1,500 W), but it climbs to 445°F (230°C), has a well-rated VeSync app and comes with nonstick accessories that Cosori lists as dishwasher-safe. It has no window and no low-temperature modes. Pick it if easy cleanup and a higher top temperature matter more to you.

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

With 6.6 quarts (6.2 L) and 2,000 W, this Philips is a better fit for households of 3 to 5. 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

5.3 quarts (5 L), 1,500 W and about ten auto presets: a simple, proven air fryer with no app. It’s a good fit if you don’t care about connectivity and want a little more room for a family of 3 or 4.

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

Its two heating elements, above and below the basket, cut down on flipping, and you control it through the VeSync app. Bigger and more premium, it fixes exactly what owners complain about most on the Xiaomi.

Setting it up

Setup is easy, but a few steps help you avoid surprises. Peel off all the protective film and stickers, wash the basket and crisper plate in soapy water, then run the empty unit for a few minutes, as most manufacturers recommend, to burn off the new-appliance smell. For the smart features, install the Xiaomi Home app, sign in or create a Xiaomi account, choose the server region that matches the version you bought (a European region for European units) and keep your phone close to the air fryer during Wi-Fi pairing. If pairing fails, make sure your phone is on the same home network, then 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 tips for use

• Overloading the basket: in a 4.2-quart basket, a thin layer gives far better results. Two batches beat one soggy one.
• Forgetting to shake: follow the unit’s reminder and shake or flip halfway through.
• Skipping the preheat: a few minutes of preheating makes fries and breaded foods noticeably crispier.
• Using metal utensils: they damage the nonstick coating. Stick with silicone or wood.
• Pushing it against the wall: leave clear space around the hot-air vent, set it on a stable, heat-resistant surface and don’t run it under low-hanging cabinets.
• Using delayed start with perishable food: remote scheduling is handy, but don’t leave raw meat or fish sitting at room temperature for hours.

The bottom line

In 2026, the Xiaomi Smart Air Fryer Pro 4L is still a sensible pick for a couple, a student or a small household that wants a compact, versatile smart air fryer. Its lit window and low-temperature modes set it apart from most rivals its size. In exchange, you have to live with 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.
