Xiaomi launched the Mijia Cordless Vacuum Cleaner 3C in China in August 2024, with sales reported to begin on September 5. The cordless stick vacuum lists a maximum suction rating of 120AW, a claimed runtime of up to 60 minutes, an anti-tangle motorized floor brush, green dust-detection lighting, and several handheld attachments. Its reported introductory price was 799 yuan, reduced from 899 yuan.

Those prices and sales details apply to the Chinese launch. An official US launch, US MSRP, and US warranty channel were not verified, so American buyers should treat the 3C as a China-market product that may require importing.

Price and availability

Xiaomi’s launch materials placed the Mijia Cordless Vacuum Cleaner 3C at 899 yuan, with an introductory price of 799 yuan. Pre-sale coverage appeared in August 2024, and sales were reported to start in China at 8 p.m. on September 5 through Xiaomi and associated retail channels.

The original yuan prices are historical Chinese launch prices, not a current US retail price. Importers must also account for international shipping, taxes, retailer margins, plug compatibility, returns, and warranty support. Xiaomi’s official product purchase page is a China-market page; it does not establish official US availability.

Key specifications

Specification Reported detail
Product type Cordless dry stick vacuum
Maximum suction 120AW, a peak product claim
Motor Brushless motor rated at up to 100,000 rpm
Battery 2,500mAh
Maximum claimed runtime Up to approximately 60 minutes
Dust bin 0.5 liter / 500 milliliters
Suction modes Three: long-lasting, standard, and strong/turbo
Filtration Nine-cone cyclone system
Floor head Motorized anti-tangle soft roller
Dust lighting 140-degree green illumination
Under-furniture access Reported 180-degree lay-flat movement

Launch reports from IT之家 and Gizmochina provide the main figures. Some reseller listings additionally describe a 250W motor, but motor wattage should not be confused with suction power.

What the 120AW rating means

The 3C’s headline specification is its maximum suction rating of 120 air watts. Air watts combine airflow and suction pressure into a measurement used by some vacuum manufacturers. They are not directly equivalent to kilopascals, motor wattage, or another brand’s proprietary suction score.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The 120AW figure should therefore be read as a maximum specification rather than a guarantee of cleaning performance. It does not show how effectively the vacuum picks up embedded debris from carpet, how well it maintains airflow as the filter loads, or how long it sustains peak output. The available launch evidence does not establish independent laboratory testing of the 3C’s pickup performance, noise, or sustained suction.

Likewise, a motor speed of up to 100,000 rpm is a supporting engineering claim, not a direct measurement of cleaning effectiveness.

Floor cleaning and visibility features

The main floor head uses a motorized soft roller designed to reduce hair tangling. That design may be useful in homes with long hair or pets, but “anti-tangle” does not mean maintenance-free. Hair, thread, and fur can still wrap around a roller, particularly after repeated use.

A 140-degree green light projects ahead of the floor head to make fine dust easier to see on hard floors and in dim areas. Xiaomi reportedly says the system can reveal up to 15 times more dust. That is a Xiaomi marketing claim, not an independently verified performance result. The light improves visibility and cleaning coverage; it does not increase suction.

Pick the symptom - the matching free tool is one click away.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The head is also reported to support approximately 180 degrees of movement, allowing the vacuum to lie flatter beneath beds, sofas, cabinets, and other low furniture. The detachable handheld configuration extends the cleaner to furniture, upholstery, curtains, car interiors, mattresses, and narrow gaps.

Attachments and dry-cleaning limits

Reported accessories include:

  • A motorized soft-roller floor brush.
  • An anti-tangle mite-removal brush for beds and upholstered furniture.
  • A crevice tool.
  • A dusting or combination tool.
  • Components for handheld cleaning.

The precise in-box bundle can vary by seller or regional package. Buyers should confirm the exact model number, attachments, and replacement-tool availability before ordering. The 3C is a dry vacuum; it should not be treated as a mop, wet vacuum, or liquid-cleanup machine.

Runtime: read “up to 60 minutes” carefully

Xiaomi advertises up to approximately 60 minutes of runtime under its stated conditions. That headline figure is most relevant to the lowest-power, long-lasting mode and should not be interpreted as 60 minutes of turbo cleaning with the motorized floor head.

Runtime changes with suction mode, powered attachments, floor type, battery condition, and the age of the battery. A reseller listing gives shorter estimates of roughly 20 minutes in standard mode and 12 minutes in turbo mode, but those figures are not official Xiaomi specifications and may apply to a particular package or test method.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

For a realistic ownership decision, ask the seller for mode-specific runtime and charging information. A single maximum-runtime number is not enough to predict how long the vacuum will last during stronger cleaning.

Filtration and maintenance

The 3C is reported to use a nine-cone cyclone filtration system. Cyclonic separation can remove some debris from the airflow before it reaches the filter, potentially slowing filter loading. It does not prove a particular fine-particle capture rate or guarantee that suction will remain at its peak.

The cordless sweeper stands on its own, allowing you to pause at any time during the cleaning process, no longer need to find a place to prop up the vacuum or worry about it tipping over.

Do not assume that the 3C has a particular HEPA grade or filtration percentage without model-specific documentation. Filters still require inspection and maintenance. A clogged filter can reduce airflow, while reinstalling a washable filter before it is fully dry can cause problems. Follow the manual or the seller’s instructions for washing, drying, replacement, and safe disposal of collected debris.

Who should consider the Mijia 3C?

The 3C is most interesting for buyers who want a feature-rich cordless vacuum for routine household cleaning and are comfortable with China-market products. It may fit particularly well in:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Homes with mostly hard floors.
  • Apartments and smaller homes needing quick daily cleaning.
  • Households that want a handheld mode for furniture, vehicles, or stairs.
  • Pet-owning homes that value a brush designed to reduce hair wrapping.
  • Buyers willing to verify import costs, support, and spare-part availability.

The 0.5-liter dust bin is adequate for regular cleaning, though homes with several pets or heavy debris may need to empty it frequently.

Who should skip it?

The 3C is a weaker choice for buyers who need an officially supported US product, guaranteed local repairs, readily available replacement batteries, or a clearly documented regional warranty. It is also difficult to recommend for thick-carpet cleaning when independent deep-cleaning results are a priority.

  • PERFECT FOR PET HAIR: Powerful suction helps pick up pet hair and everyday debris from carpets and hard floors, while the included Pet Multi-Tool tackles embedded pet hair on upholstery and furniture

Buyers seeking wet cleaning or automated floor cleaning should look elsewhere: this is neither a wet-dry cleaner nor a robot vacuum. The name “3C” can also cause confusion with unrelated Xiaomi robot-vacuum products, so verify that the listing specifically identifies the Mijia Cordless Vacuum Cleaner 3C.

Import checklist

Before purchasing an imported unit, confirm all of the following with the seller:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Whether the seller ships to your country.
  2. The final landed cost, including shipping, taxes, and fees.
  3. The charger’s input rating and the supplied plug type.
  4. Return procedures and warranty coverage in your country.
  5. Availability and price of filters, rollers, batteries, and other consumables.
  6. The exact accessory bundle and product model number.
  7. Whether any advertised app features are supported in your region. Available evidence does not establish that the 3C requires Mi Home or Xiaomi Home connectivity.

One reseller listing mentions 100–240V input and a European plug, but that information may apply only to that particular package. Verify it rather than assuming every imported 3C includes the same charger.

Mijia 3C versus Mijia 4C

The Mijia Cordless Vacuum Cleaner 3C should not be confused with the newer Mijia Vacuum Cleaner 4C listed on Xiaomi’s global website. The 4C advertises up to 170AW of suction, up to 75 minutes of Eco-mode runtime, and five-stage filtration. Those figures belong to the 4C, not the 3C.

The global 4C page may be a more relevant starting point for readers seeking a newer Mijia model with a global-facing product page, but it still does not by itself prove US pricing, stock, or local support.

Verdict

On paper, the Xiaomi Mijia Cordless Vacuum Cleaner 3C combines a strong claimed suction figure with useful everyday features: a motorized soft roller, dust-visibility lighting, handheld conversion, lay-flat access, and a dedicated upholstery brush. Its reported Chinese launch pricing also positioned it as a budget-oriented alternative.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Its value outside China is less straightforward. The 60-minute runtime is a low-power maximum, the 120AW rating is not an independent cleaning test, the 15-times dust-visibility statement is promotional, and local parts and warranty support may be difficult to verify. For import-ready buyers with mostly hard floors, it could be appealing. For shoppers who prioritize dependable regional service or tested carpet performance, a locally supported cordless vacuum is the safer choice.
