Making the best choice for a central vacuum

How to Choose a Central Vacuum?

Choosing a central vacuum is above all choosing a long-term investment for your home. Unlike a portable vacuum that you will replace every 3 to 7 years, a well-chosen central vacuum will serve you for 25 to 40 years. It is therefore essential to take the time to compare models according to your actual needs before making a decision.

At Vacuums Online, we have been central vacuum specialists in Quebec since 1985. Our team is here to help you find the centralized vacuum system that perfectly matches your type of home, your surfaces to clean, and your budget.

What Criteria Should You Compare When Choosing a Central Vacuum?

When comparing central vacuums, several technical and practical criteria come into play. Here are the main elements to evaluate to make the best choice.

Suction Power

Power is arguably the most important criterion. It is measured primarily in inches of water ("H2O), which represents the raw suction force. The higher the number, the more effective the central vacuum will be at lifting heavy debris such as crumbs, gravel, or cat litter.

Two other units complete the picture: airflow in CFM (cubic feet per minute), relevant for large homes with multiple inlet valves, and Airwatts, obtained by the formula CFM x "H2O / 8.5. For a typical family home, the inches of H2O remains the most reliable indicator.

Filtration Type

Filtration is what truly distinguishes a central vacuum from a portable vacuum. A central vacuum with HEPA certification filters up to 99.5% of dust particles. Combined with a fabric or paper recovery bag, it filters dirt twice rather than once — ideal for people with allergies or respiratory problems.

Some models can also be vented directly outside the home through a 100% sealed exhaust air outlet — the ultimate solution for optimal indoor air quality.

With or Without a Dust Bag?

This is one of the most frequent questions when choosing a central vacuum. Bagged models offer cleaner, less messy maintenance — simply remove the full bag without handling any dust. Bagless models are more economical in the long run since there are no bags to purchase. In both cases, the capacity of a central vacuum is 15 times greater than that of a portable vacuum, meaning far less frequent emptying.

The Size of Your Home

Each central vacuum is designed to cover a certain area. It is important to choose a model whose power and airflow match the size of your home and the number of inlet valves you wish to install. For a medium-sized home with 2 to 3 floors, an intermediate model will be more than sufficient. For a large residence or commercial project, a more powerful motor with a high CFM will be preferable.

Brand and Durability

We carry the best central vacuum brands available in Canada: Beam, CycloVac, Drainvac, DuoVac, Electrolux, MVac, Ovo, Vacuflo, AirStream and several others. Each brand has its own characteristics in terms of power, filtration, noise level, and warranty. Some motors, particularly permanent induction motors, can last up to 40 years with minimal maintenance.

Central Vacuum vs. Portable Vacuum: The Comparison That Makes You Think

Here is why, in light of an honest comparison, the central vacuum stands out as the smartest choice:

  • Power: A central vacuum is at least 10 times more powerful than your typical portable vacuum
  • Lifespan: Over 25 years for a central vacuum, versus 3 to 7 years for a portable vacuum
  • Capacity: A central vacuum's capacity is 15 times greater than that of a portable vacuum
  • Air quality: A central vacuum exhausts dust outside or filters it at 99.5% — a portable vacuum blows it back into the same room
  • Silence: Installed in the basement or garage, a central vacuum is virtually inaudible in your living spaces
  • Comfort: No more hauling a bulky canister up the stairs — only the lightweight hose accompanies you
  • Long-term cost: For less than $1,000, motor unit, accessories, and installation materials included, a central vacuum pays for itself with the very first replacement avoided
  • Ecology: A lifespan of 25 to 40 years, fewer disposable bags, no lithium batteries to recycle

Can a Central Vacuum be Installed in an Existing Home?

Do you think a central vacuum is only possible in new construction? This is a very common misconception. It is entirely possible to install a central vacuum in an existing home, and our technicians do it regularly throughout Quebec.

The key is to carefully plan the piping route. The compartment under a staircase, a closet, or a mechanical room often serves as an ideal starting point to distribute the pipes to each floor. A wardrobe or closet can also serve as a discreet vertical passage between levels. In some cases, a 60-foot flexible hose can cover the entire home from a single strategically placed inlet valve.

Our team can assist you in evaluating your home and recommend the optimal configuration based on your floor plan, budget, and cleaning habits.

Which Central Vacuum Should You Choose for Your Budget?

There are quality central vacuums for every budget. Here is a general overview of the available ranges:

  • Entry-level (under $500): Ideal for small homes or condos. Sufficient power for smooth surfaces and light carpets.
  • Mid-range ($500 to $900): The best value for money for a typical family home of 1,500 to 3,000 sq. ft. HEPA certification, durable motor, multiple accessory options.
  • High-end ($900 and up): Permanent induction motor, maximum power, advanced filtration, extended warranty. For large homes, allergy sufferers, or those who want the best without compromise.
