Vacuum Cleaner Buying Guide: 11 Features You Need to Know

Did you know the Australian market is expected to sell 5.2 million vacuum cleaners by 2035? In fact, it’s long been a staple appliance in our households. But with so many options out there, choosing the right vacuum cleaner can quickly feel overwhelming. From suction power, filtration systems, docking station size, noise levels, to price points and smart features, there’s a lot to compare, and it’s wise to get a basic idea of the most essential features before you shop.

Are Traditional Vacuums Still Worth It?

Yes, traditional vacuums are still worth it today. Compared to newer types like high-end stick vacuums or robotic vacuum cleaners, classic models offer a solid balance of cost, performance and functionality.

Within an affordable price range, it’s easy to find vacuums with strong suction power for lifting debris trapped between carpet fibres, and larger dustbins for holding collected dust, making them popular for layered rugs or carpeted stairs. Plus, they offer a wider price range to cater to different budgets.

If you're looking for a dependable cleaner that gets the job done, a traditional vacuum remains a great choice.

Key Features to Look For When Choosing a Vacuum Cleaner

When picking a vacuum for yourself, it comes down to understanding key features. Remember that effective cleaning isn’t just about raw power, but also airflow, roller brushes, air ducts and filtration systems that work for your floors, your family, and even your noise tolerance.

1. Suction Power

Typically measured in air watts (AW) or pascals (Pa), a vacuum’s suction power is the “muscle” that determines its cleaning performance. Generally speaking, aim for at least 200 AW to lift stubborn dirt or pet hair on carpets. On the other hand, lower power around 100–150 AW is sufficient for hard floors. A good suction power range is 180 to 200 AW for traditional vacuums and 2,500 to 6,000 Pa for robot vacuums; but don’t obsess over numbers alone; a well-designed vacuum pairs suction with smooth airflow to clean efficiently.

2. Filtration System

Once the vacuum picks up debris, a highly efficient filtration system traps fine dust, allergens, and pet dander to prevent them from being released back into the air.

For allergy sufferers or pet owners, a good filter is particularly important, like HEPA filters capture up to 99.97% of particles. A multi-layer filtration system can also do a great job for home use. To keep your vacuum performing at its best, clean and replace the filters regularly.

3. Noise Level

A quieter vacuum cleaner makes cleaning much less disruptive for kids, pets and those working from home. For instance, robot vacuums with smart navigation run well at night when set to quiet mode.

As a reference, vacuum cleaner noise levels between 60 and 85 decibels (dBA) are generally considered acceptable.

4. Vacuum Performance & Debris Pickup

Other than suction, cleaning efficiency involves features such as good airflow and smart design to make fewer passes over the same spot. Things like adjustable suction let you switch to hard floors without scattering debris.

Got a shedding dog or long-haired housemate? Look for anti-tangle brushes to save you the hassle of removing hair from the vacuum rollers.

5. Dustbin or Bag Capacity

Bigger bins or bags mean less emptying, which is a lifesaver for pet owners or big families. Today, vacuums come in both bagged and bagless designs:

- bagged vacuums are more hygienic and convenient for allergy sufferers;

- bagless models are simpler to empty and more eco-friendly.

Pick what suits your routine.

6. Price and Warranty

Based on features and technology, vacuum cleaner prices vary widely from under AUD100 to well over AUD1,000. While budget-friendly models can work fine, many people choose to invest in a premier vacuum with stronger suction, better filters, and a solid build.

Regular maintenance, like emptying the bin or cleaning the brushes, helps the machine run smoothly over time; also, check the warranty and available service options in case repairs are needed.

7. Versatility Across Surfaces

A good vacuum should transition easily between tile, carpet and hardwood floors. Opt for adjustable suction levels and brush height, so they can lift embedded dirt from carpets while vacuuming laminate floors without causing damage.

Some smart models even detect the surface and adjust settings automatically, which is a nice touch if you’ve got a mix of floors; while manual switches offer better control.

8. Smart Features

Commonly seen in robot vacuums and high-end models, vacuum cleaners now offer high-tech features like real-time mapping, self-emptying, remote app control and mopping functions. Just make sure the smart features are user-friendly and compatible with your smart home systems like Alexa or Google Assistant.

9. Size, Weight and Storage

The size and weight of a vacuum matter, particularly for small apartments or seniors who need something lightweight.

Slim vacuum cleaners are easier to manoeuvre in tight spaces and reach corners, while foldable handles or compact charging stations are great for limited storage areas.

If you're looking for vacuums that are easier to store, robot vacuums are a good option since they are slim and can slip under most furniture like couches and cabinets.

10. Attachments and Accessories

Attachments expand the cleaning scope of your vacuum and work on more than just floors. For example, pet owners should search for turbo brushes or tangle-free tools designed specifically for fur.

Other common accessories include crevice tools, dusting brushes, upholstery tools and edge cleaners.

11. Maintenance

Similar to other home appliances, vacuums need regular upkeep to stay in top shape. This includes emptying the dustbin, cleaning filters, decluttering the brushes, and wiping down the exterior.

Clogged systems, reduced suction and even motor damage can potentially cause the vacuum to spit out dust or stop unexpectedly. Some smart models send alerts when it’s time for maintenance, which takes the guesswork out.

Select a Vacuum Cleaner That Matches Your Needs

Understanding your needs is the first step in selecting the right vacuum cleaner. You can prioritise certain features to match your needs.

● Allergy sufferers: strong filtration system and scheduling.

● Pet owners: strong suction and tangle-free brushes.

● Small apartments: compact vacuum design and quiet mode.

● Large houses: larger dustbin capacity and extended battery life.

● Carpeted homes: motorised brush rolls and ability to climb high thresholds.

● Multi-floor homes: mapping technology and lightweight design.

Take pet fur, for instance. Models like DEEBOT robot vacuum and mops feature powerful suction, remote scheduling, anti-tangle brushes and sealed dustbins, hence you can let them run all day to keep fur under control and minimise the risk of allergies.

Ultimately, choose a vacuum cleaner that answers your needs, from home size, cleaning frequency, to how much storage you have. A bit of research goes a long way in finding the perfect match.
