Important indicators to pay attention to when purchasing a cordless vacuum cleaner

Suction power (Pa/AW/Air Watt)

This is the primary indicator for measuring a vacuum cleaner's cleaning power. The greater the suction power, the better it is at removing deep-seated dirt and stubborn debris. Common indicators include Pascals (Pa), Air Watts (Air Watt), and AW.

• For normal hard floors (wooden floors, tiles): 12,000–15,000 Pa or 80–100 AW is sufficient.
• For homes with carpet: ≥ 20,000 Pa or 120 AW is recommended.
• For homes with pets: Higher suction power (≥ 25,000 Pa) is required, along with an anti-tangle brush head.

It’s important to note that suction power depends not only on motor power but also on airway design and sealing. Many low-priced models claim high suction power, but the actual experience is poor. This is a case of false labeling.

Battery and Runtime

The battery life of a cordless vacuum cleaner determines how much of your house you can clean at once and how often you need to recharge it.

• Battery life: Typically 30–60 minutes, with 20–30 minute models available for smaller homes.
• Battery type: Primarily lithium-ion, with removable and replaceable batteries for added flexibility.
• Charging time: Fast charging takes 2–3 hours, while standard models may take 4–5 hours.

Removable Battery: If you have a large home or want uninterrupted cleaning, a model with a removable battery is more convenient. You can also purchase a spare battery to use alternately.

Charging Time: Charging time also affects the user experience. It typically takes about 3-5 hours.

HEPA Filtration System

The filtration system is a crucial factor to consider when purchasing a vacuum cleaner. It determines whether the vacuum cleaner effectively traps fine dust and allergens, preventing secondary contamination. This is particularly effective for people with allergies.

HEPA filtration: A good cordless vacuum cleaner typically features a multi-layer filtration system, with the HEPA (High Efficiency Particulate Air) filter being the most critical. It removes 99.97% of tiny airborne particles (as small as 0.3 microns), such as pollen, dust mites, and pet dander.

Washable filters vs. disposable filters: Cleaning filters is inexpensive but requires regular drying. Disposable filters are easy to maintain but require regular replacement. Airtightness of the entire unit: Prevents secondary dust emissions and improves air quality.

Brushes & Accessories

Different brush heads allow cordless vacuum cleaners to adapt to a variety of cleaning scenarios. Their diversity and practicality are important criteria for measuring the versatility of the product.

• Motorized Roller Brush: A good floor brush should be adaptable to different flooring materials (such as hard floors and carpets) and feature a hair-tangle-resistant design. Essential for deep carpet cleaning.
• Crevice Nozzle: For cleaning tight areas like corners and sofa crevices.
• Two-in-one Brush: Ideal for cleaning keyboards, curtains, and tabletops.
• Mite Removal Brush: If you have pets or are allergy-sensitive, a professional electric mite removal brush is essential.
• Hose and Extension Pole: Convenient for cleaning high areas or inside the car.
• Hard Floor Brush/Soft Bristle Brush: Protects wood floors and removes debris.
• Anti-Tangle Pet Hair Brush: Eliminates hair tangles.
• Crevice Nozzle & Extension Pole: Ideal for bed seams, sofas, and car interiors.

Recommendation: Choose a combination of accessories based on the actual cleaning scenario at home.

Dustbin Capacity

This directly impacts your cleaning frequency and convenience. It's usually measured in liters (L).
Small apartments/dorms: 0.5L is sufficient. If you live in a small home and are in the habit of cleaning regularly, a smaller dust cup will suffice.

Medium-to-large apartments: ≥ 0.8L, reducing cleaning frequency. Suitable for medium-sized apartments (two- and three-bedroom apartments). Generally, cleaning the entire house in one go is not a problem, eliminating the need for frequent trash removal.

Weight & Ergonomics

A vacuum cleaner's weight and design directly impact its ease and comfort.

• Lightweight: ≤ 3kg is optimal, ensuring easy handheld operation. The lighter the vacuum cleaner, the less effort it takes to use, especially when lifting it to clean curtains or ceilings or for extended periods.
• Center of Gravity Design: The handle and body are balanced, ensuring effortless cleaning even for extended periods.
• Dust Collection: One-touch or push-button vacuuming is recommended for quick and easy operation without getting your hands dirty.

Optional Smart Features

LED/LCD Display: This is one of the most common smart features. The screen can display the battery level, current suction mode, filter status, and fault prompts in real time.

Automatic floor type recognition: When switching from hard floors to carpets, for example, the vacuum cleaner automatically increases suction power for better cleaning results. This eliminates the need to manually adjust the suction power setting.

Intelligent suction control: Some vacuum cleaners can also sense the amount of dust. When heavy dust is detected, the suction power is automatically increased, and otherwise reduced to conserve power. This maximizes battery life while maintaining effective cleaning results.

Choose the right model according to your living

For small apartments (under 60 square meters), dormitories, or one-bedroom apartments, portability and flexibility are key requirements. Choose a lightweight model weighing under 1.5 kg for easy one-handed operation and storage. A battery life of around 30 minutes is sufficient.

Suitable accessories: Soft brush and crevice nozzle for cleaning desks and bed crevices.

Medium-sized homes (60-120 square meters): This is the size of most homes, requiring a vacuum cleaner that balances battery life, suction power, and versatility. We recommend choosing a model with a 45-60 minute battery life to ensure a full house clean without recharging.

Suitable accessories: Electric roller brushes and anti-tangle brushes are suitable for occasional cleaning of pet hair or carpets.

For larger apartments (over 120 square meters): Be sure to choose a model with a battery life of at least 60 minutes, preferably one with replaceable or dual batteries to handle large cleaning areas.

Suitable accessories: A full set of brush heads (motorized roller brush, soft-bristle brush, crevice nozzle, pet brush) are available to suit various cleaning scenarios.

Special environment: pets or carpets

If you have pets or a lot of carpet in your home, you'll need a more specialized vacuum cleaner.

• Suction Power: Choose a model with strong suction to effectively remove pet hair and dander deep inside carpets.
• Brush Head: A brush with an electric anti-tangle brush and an anti-mite brush is essential. The former prevents hair from getting tangled, while the latter effectively removes allergens from beds and sofas.
• Filtration System: A HEPA filter is crucial, effectively trapping pet dander and fine dust, preventing secondary contamination and protecting your family's respiratory health.

Recommended cordless vacuum cleaners for different cleaning scenarios

Home Hard Floor Cleaning

For general household use, a suction power of at least 12 kPa or 120 AW is sufficient for daily cleaning. Paired with a soft-neck floor brush, it effectively absorbs dust and debris while protecting the floor.

Living Room and Bedroom Carpets & Rugs

We recommend selecting a suction power of 18 kPa or higher, or between 140 and 180 watts (AW), to tackle deep-seated dirt and hair. Use a high-torque carpet brush, whose powerful rotational force penetrates deep into carpet fibers, thoroughly removing trapped dust and hair.

Fabric cleaning such as mattresses, sofas and curtains

The suction force needs to balance static and dynamic pressure, and the strong gear is usually selected to fully utilize the flapping and adsorption functions. The high-speed rotating flapping function of the electric mite removal brush can shake off deep-seated mites and dust, and the strong suction force draws pollutants into the dust box, effectively reducing allergens.

For households with pets (cats and dogs with lots of hair)

Hair easily tangles around the brush head, and allergens are easily present in the air. This brush features a suction force of ≥22,000 Pa and a tangle-resistant brush. The tangle-resistant motorized brush head efficiently removes hair without clogging. The HEPA filter removes allergens and pet dander.

For those with allergies and families with children

Recommended: a fully sealed filter system with HEPA H13/H14 filters, filtering 99.95% of fine dust. The anti-recontamination design provides strong and stable suction. The quiet design (≤70dB) minimizes noise levels and prevents disturbing your baby's sleep.

Conclusion: Choosing the Right Vacuum Cleaner: From "Cleaning" to "Enjoying"

Purchasing a cordless vacuum cleaner isn't simply a matter of comparing specs; it's about choosing a more efficient and comfortable lifestyle for you and your family. From suction power and battery life to accessories and smart features, every aspect matters to your actual user experience.

There's no "best" vacuum cleaner, only the one that's "best" for you.
