Xiaomi has brought a new oversized refrigerator to Europe, and it is exactly the kind of appliance that tries to be both practical and a little smug about it: the Mijia Side-by-Side 621L. It costs 850 euros, offers 621 liters of storage, skips manual defrosting, and plugs into Xiaomi’s home ecosystem so you can check the temperature from your phone instead of walking to the kitchen like it is the 1990s.
The Xiaomi Mijia Side-by-Side 621L is aimed at big households, with 385 liters in the fridge section and 236 liters in the freezer. Xiaomi says it has adjustable shelves, multiple storage zones, No Frost cooling, and an Ag+ module designed to reduce bacteria and odors. That puts it squarely in the growing smart-appliance segment, where convenience features matter almost as much as raw capacity.
621 liters and No Frost cooling
The headline number is the size. At 621 liters, the Mijia Side-by-Side 621L is aimed at families that actually need freezer space, not just a place to hide ice cream and leftovers. The No Frost system means there is no manual defrosting, which is less glamorous than app control but far more useful over the long run.
Xiaomi also says the unit uses an inverter compressor and runs at 35 dB, a quiet enough figure for open-plan homes where kitchen noise has become part of the furniture. Its dimensions are 910 × 715 × 1770 mm, so this is not a compact city fridge pretending to be one.
Xiaomi Home, Google Assistant and Alexa support
The smarter part of the story is the software layer. Through Xiaomi Home, users can check temperatures remotely, switch cooling modes, and get alerts if the door is left open. Voice control also works with Google Assistant and Amazon Alexa, which is the sort of cross-platform support that makes a connected appliance feel less like a locked-in experiment.
That puts Xiaomi in familiar territory: competing not just on price, but on feature density. European appliance brands have been adding similar connected functions for years, yet many still charge more for less capacity. At 850 euros, Xiaomi is clearly betting that buyers will forgive the lack of luxury branding if the spec sheet keeps overdelivering.
The anti-bacterial module is the extra flourish
The Ag+ module is the kind of feature that sounds minor until you have lived with a fridge that smells faintly of onions and regret. Xiaomi says it provides antibacterial and deodorizing effects, which adds another layer to a product that is already leaning hard on convenience and maintenance-free ownership.
- Price: 850 euros
- Total capacity: 621 liters
- Fridge compartment: 385 liters
- Freezer compartment: 236 liters
- Noise level: 35 dB
- Size: 910 × 715 × 1770 mm
The real question now is whether Xiaomi can turn a solid spec sheet into a serious European appliance business. Smart-home integration helps, but refrigerators are a brutally practical category: people buy them for years, not for novelty. If the company can keep undercutting established rivals while matching their reliability, this could be a much bigger story than one very large fridge.
