Before we discuss the optimal vacuum cleaner, we need to define what that entails. We can’t talk about high-quality vacuum cleaners without discussing the different types and what distinguishes them:
- Vacuum cleaners with or without a bag
- Central vacuum systems
- Handheld, cordless, and robotic vacuum cleaners
The factors we will focus on are:
- Suction power and efficiency
- Filtration system
- Energy efficiency
Although it doesn’t affect cleaning quality, we’ll also review these important factors:
- Ergonomics
- Maintenance
Vacuum Cleaners with or without a Bag
Bagged vacuum cleaners have been around for over 100 years. These are often referred to as “classic” vacuums and are mainly used by homeowners. Professional cleaning companies, especially those servicing large spaces, use vacuums with higher suction power.
Classic vacuums typically use disposable bags that need to be changed regularly, which creates waste and can be less environmentally friendly, especially if the bags are plastic-based. On the plus side, bagged vacuums are more hygienic since dust and dirt are collected in a sealed bag that can be discarded without exposure to the contents.
Bagged vacuums effectively capture small particles thanks to the bag, which acts as an additional filter. Combined with HEPA filters, they provide excellent filtration, resulting in cleaner air and reduced allergens in the home.
Bagless vacuums use a dust container that you empty when full, eliminating the need for bags, which can be more cost-effective long-term. However, when emptying the container, dust can be released, which can be an issue for people with allergies or asthma.
Bagless vacuums often have multiple filters that need regular cleaning to maintain suction power and efficiency, which can be time-consuming. Additionally, as they lack sealed bags, odors can sometimes escape from the container, especially if it isn’t cleaned regularly.
Central Vacuum Systems
A central vacuum system is a permanently installed unit with the main unit located in a remote place, such as a garage or basement, connected to wall outlets throughout the home. Dust is collected in a large container in the main unit, which only needs to be emptied a few times a year.
Central vacuums offer several advantages: they’re quieter than regular vacuums because the motor is placed far from the rooms, and they have strong suction power that’s effective on both hard surfaces and carpets. They also improve indoor air quality as dust and allergens are transported out of the rooms, reducing recirculation risks.
One downside is the high installation cost, especially if retrofitted into an existing house. Additionally, the long hose can be cumbersome to maneuver.
Handheld, Cordless, and Robotic Vacuums
Handheld vacuums are convenient for smaller areas or quick clean-ups. However, their battery life and limited suction make them more suitable for cleaning furniture or car interiors than a full home cleaning.
Cordless vacuums are larger than handhelds but more lightweight and flexible than traditional vacuums. They’re battery-operated, giving you the freedom to move around the home without switching outlets or dealing with cords. They’re popular for quick, easy cleaning, and some models are powerful enough to replace a traditional vacuum. Many cordless vacuums have detachable handheld units and various attachments for floors, furniture, and other surfaces.
Robotic vacuums are automated, self-propelled devices that navigate through the home, cleaning floors independently. They’re especially popular for regular maintenance cleaning, as they can be scheduled to clean on a set schedule. Some models feature advanced navigation and sensors to avoid obstacles and can be controlled via an app or voice commands. They’re ideal for daily upkeep, though they don’t match the efficiency of traditional vacuums.
Power and Suction
Power is measured in watts (W) and indicates the energy consumption of the vacuum’s motor. High wattage often suggests a powerful motor, but it doesn’t necessarily mean better suction. Suction strength depends on factors such as design, filtration, and nozzle efficiency. Wattage only indicates energy usage, not the vacuum’s actual cleaning performance.
Suction power is crucial for effective dust and dirt removal. Look for vacuums where suction power is specified. The optimal suction range for a vacuum is generally between 100-300 AW, depending on usage and floor type:
- Light Cleaning (hard floors, laminate, parquet): 100–150 AW is usually sufficient to capture dust and small particles.
- General Household Needs (mixed surfaces, carpets, and hard floors): 150–250 AW is recommended for effectively capturing dust, dirt, and some pet hair. For example, Dyson’s V15 provides 240 AW of suction power.
- Heavy Cleaning (thick carpets, pet households): For homes with carpets, pet hair, or stubborn dirt, a suction power of at least 250 AW is recommended for deep cleaning.
Filtration System
Different filters commonly found in vacuum cleaners include:
- HEPA (High-Efficiency Particulate Air)
- ULPA (Ultra-Low Penetration Air) filters
- Carbon filters
- Microfilters
- Foam filters
If you or anyone in your household suffers from allergies, a HEPA filter is ideal. These filters capture most allergens and small particles, improving indoor air quality. HEPA filters can trap particles down to 0.3 microns with at least 99.97% efficiency, including pollen, mold spores, dust mites, and other allergens.
ULPA filters are even more efficient than HEPA filters, capturing particles as small as 0.12 microns with 99.999% efficiency. They are rarely used in household vacuums due to their high cost and over-capacity for most residential needs.
Carbon filters are mainly for odor removal, absorbing gases and odor particles, though they aren’t effective at capturing allergens or small particles.
Microfilters capture larger particles like dust and debris, typically placed before the motor to prevent damage. They aren’t designed to trap allergens.
Foam filters are made of porous foam that captures larger particles and protects the vacuum’s motor. They’re less effective at capturing fine particles and allergens and work best in conjunction with other filters like HEPA.
Energy Efficiency and Sustainability
Energy efficiency does not impact cleaning quality but is an important consideration. In Europe, vacuums have an energy rating from A+++ to D, with A+++ being the most energy-efficient.
Vacuum cleaners today are designed to have lower power consumption (up to 900 watts, per EU regulations from 2017), while still providing strong suction power thanks to improved motors and aerodynamic designs.
Ergonomics
Ergonomics may not affect cleaning quality but has a significant impact on user comfort. The vacuum’s weight matters, as heavier models place more strain on the body. Vacuums with longer cords require fewer outlet changes, and cordless vacuums eliminate this issue entirely. Many vacuums come with special nozzles that simplify cleaning for carpets, parquet, tight spaces, and pet hair.
Robotic vacuums are ideal ergonomically since they reduce the need for manual effort, though they are best for maintenance cleaning and not as effective for deep cleaning.
Maintenance
Proper vacuum maintenance is just as important as its suction capacity for hygiene. Vacuums with multiple moving parts and filters that require regular cleaning or replacement need more upkeep. Choose a model that’s easy to clean and with readily available replacement parts if something breaks.
Conclusion
Which type of vacuum cleaner is best for effective, hygienic home cleaning? An AirWatt (AW) rating of 150-250 is ideal; avoid models that don’t specify AW. For most users, a classic bagged vacuum with a HEPA filter is ideal for thorough, hygienic cleaning. If ergonomics is a priority, a cordless vacuum may be best for you.
