Central Vacuum Power Units in Canada: Sizes, Brands & Prices
Central Vacuum Power Units | How to Choose the Right One for Your Home
A central vacuum power unit is the motor and dirt canister at the heart of your system, and it decides how well the whole system performs. A bigger unit isn't automatically better: you want the right capacity, motor type, and filtration for your home's size and flooring. This guide covers how to choose and what to compare across the brands we stock.
What Is a Central Vacuum Power Unit?
A central vacuum power unit is a motor-and-canister assembly installed in a garage, basement, or utility room. It connects to wall inlets through sealed tubing. You plug a lightweight hose into an inlet, and dirt travels through the pipes to the unit. Because the motor sits away from your living space, the cleaning area is much quieter than with a portable vacuum.
Our central vacuum power unit collection includes CanaVac, DrainVac, DuoVac, Nilfisk, and Cyclovac units.
Quick Answer: How Do I Choose a Power Unit?
- Match capacity to home size. Use the manufacturer's rated square footage, and size up for thick carpet, pets or long pipe runs.
- Check motor power. Look at air watts and water lift, not just amps.
- Pick your filtration style. Bagged units keep disposal cleaner, and filtered or cyclonic designs reduce bag changes.
- Plan the location. Choose a spot near a power outlet with room for service and, where required, exhaust venting.
Match the Unit to Your Home Size
| Power unit package | Rated coverage | Notable features | Price (CAD) |
|---|---|---|---|
| CanaVac ACAN590A Signature Series | Up to 5,000 sq ft | Low-voltage air package | From $929.95 |
| CanaVac ACAN70A | Up to 7,000 sq ft (8,000 with electric packages) | Flow-thru motor | From $719.95 |
| DrainVac S1008 | Compact installs | 800 air watts, canister shows when the bag is full | From $849 |
| DrainVac G2-008 | Up to 8,500 sq ft | 800 air watts, 9 gal (41 L) capacity | From $959 |
| Nilfisk Supreme 250 | About 2,690 sq ft | European-designed, quiet | From $889 |
Prices are for complete packages that include the power unit and cleaning kit, as listed on October 1, 2026.
For the Nilfisk, the manufacturer rates the Supreme 250 for houses up to 250 sqm or a pipeline of up to 50 metres, roughly 2,690 square feet. For larger homes, step up to a DrainVac or CanaVac model.
Motor Type: What Matters
Air Watts and Water Lift
Air watts measure usable cleaning power at the hose, combining airflow and suction. Water lift measures suction alone. Long pipe runs and dense carpet reward higher airflow, so don't buy on one number.
Flow-Thru vs. Bypass Motors
Flow-thru motors pass the dirty airstream through the motor, which keeps the design simple and powerful. Bypass motors keep that airstream separate, which some owners prefer for durability. Both work well in quality units, and the right choice depends on the model and your priorities.
Features Worth Paying For
- Filtration: Bagged units keep dust sealed in during disposal. See central vacuum bags and filters for replacements.
- Canister capacity: A large canister means fewer trips to empty it. The DrainVac G2-008 holds 9 gallons.
- Low-voltage controls: Wall inlets run a low-voltage signal to start the unit, so you don't need a switch on the unit itself.
- Noise control: Soundproofed casings and mounting location both reduce noise.
Installation Tips From Our Team
Mount the unit on a solid wall at a comfortable height, near an outlet and with space for bag changes. Keep piping runs short with gentle bends, since every elbow reduces airflow. Check your model's requirements for venting exhaust outdoors. Our installation supplies cover fittings, pipe, and inlets, and our team can help plan a retrofit.
Frequently Asked Questions
How long does a central vacuum power unit last?
Lifespan depends on the model, usage, and maintenance. Regular filter and bag changes help, and many units run for well over a decade. Check the warranty for the specific unit you choose.
What size power unit do I need?
Match the unit's rated coverage to your home's square footage, then go one step up if you have thick carpet, pets or a long pipe run.
Are central vacuum power units quiet?
Much quieter than portable vacuums, because the motor is remote. Units vary, and Nilfisk models are marketed for especially quiet operation.
Can I replace just the power unit in an existing system?
Usually yes, if the new unit's inlet size and electrical requirements match. Call us with your current model, and we'll confirm compatibility.
Do I need a professional to install one?
Many handy homeowners install their own, but wiring and venting should follow local codes. Ask us about installation supplies or call for guidance.
Does a central vacuum help with allergies?
Because dust is carried through sealed tubing to a remote canister, less of it is recirculated in living areas. Filtration quality and proper venting still matter.
Does The Vacuum Store ship power units across Canada?
Yes. Orders over $99 ship free, backed by a 110% money-back guarantee and a best price guarantee.
