To ensure you get the best product for your family's needs, consider these 8 key factors when selecting a vacuum cleaner:
Clarify Needs and Usage Scenarios
1.Floor Type: Are you primarily cleaning carpets or hard floors (wooden floors, tile)? Carpets require a vacuum cleaner with a motorized roller brush, while hard floors have less demanding requirements for the brush material.
2.Family Circumstances: Do you have pets (prone to shedding), allergies (need to prioritize the filtration system), or stairs or high places (affecting weight and accessory selection)?
3.Usage Frequency and Area:For larger homes (>100㎡), prioritize large dustbins/bags, long battery life (cordless models), or robotic vacuums/vacuum cleaners with automatic recharging.
4.Suction Power and Cleaning Efficiency:
Suction Power Parameters: AW (watts) is more scientifically accurate than Pa (Pascals). AW combines vacuum level and airflow, reflecting actual cleaning ability. For general cordless vacuum cleaners: 100AW and above is sufficient for daily use, 150AW+ offers better performance, and 200AW+ is flagship level. Actual Testing: Refer to the suction ball/rice/vacuum tests in the review, as well as the cleaning effect of the roller brush on crevices (corners, baseboards) and long hair entanglement.
Filtration System
5.HEPA Filter: Must have multi-stage cyclone separation + HEPA filter (at least H12 or higher). This prevents dust from being ejected again, especially friendly to allergy sufferers.
Washability: Whether the filter is washable (note drying time) or needs replacement (cost).
Cyclone Separation Technology: Good cyclones (such as Dyson, Puppy, etc.) reduce filter clogging and maintain consistent suction power.
Dust Collection Method and Capacity
With Dust Bag vs. Without Dust Bag:
Without Dust Bag (commonly cordless handheld): Requires manual emptying; some have a "one-button emptying" function, but dust is easily stirred up. Dust box capacity is generally 0.3-0.8L; larger homes require frequent emptying.
Corded vs. Corded Vacuum Bags (mostly corded or canister-style): Large capacity (2-10L), bags need changing every 2-4 months, no dust generation, but consumables need to be purchased.
Latest Trend: Some brands (such as Samsung, Dreame, and Puppy) have "automatic dust collection stations"-when the cordless vacuum cleaner is placed back in the station, it automatically sucks the dustbin's contents into the dust bag, balancing convenience and hygiene.
Corded vs. Corded
Corded (Handheld/Stick): Convenient, ready to use anytime, but limited battery life (generally 5-15 minutes on the strongest setting, 30-60 minutes on the eco setting), and suction power is usually weaker than corded models in the same price range. Suitable for small to medium-sized apartments and quick daily cleaning.
Corded (Canister/Traditional Stick): Strong suction, unlimited battery life, low price, but inconvenient with the power cord. Suitable for large apartments, post-renovation cleaning, and deep cleaning.
Battery Life (for Corded Models)
Replaceable battery design is a plus (an extra battery for unlimited battery life).
Charging time (2-4 hours is common).
Low battery warning and automatic mode switching.
Accessories and Functionality
Essential Accessories: Crevice tool (windowsills, sofa seams), brush tool (keyboards, blinds), mite removal tool (mattresses).
Practical Designs: Soft roller brush (protects floors), anti-tangling roller brush (for pets), LED light/green dust indicator (visible for fine dust), charging stand (wall-mounted or floor-standing).
Extended Functions: Ability to remove mites, compatibility with a wet mopping module (note that the mopping function usually only wets the cloth, not deep-cleaning).
Weight and Handling
Overall weight (especially the center of gravity of the handheld part). Lightweight version <2kg, heavy-duty version >3kg.
Roller brush steering flexibility, low center of gravity design (for cleaning under beds).
Handle grip comfort, whether it requires effort during prolonged use.
