Buying a central vacuum is a considerable investment and there are many factors to consider when choosing one. This article will show you which features are most important in order to choose a good vacuum cleaner.

Determining The Power Of A Vacuum Cleaner

The power of a vacuum cleaner is calculated in air watts, this measure is the ratio between the airflow, the suction and the power consumption. Most vacuum cleaners have a power between 600 and 700 air watts. However, Drainvac offers models up to 800 air watts such as the S1008, the G2-008 or the DV1R800. The G2-2X5 even offers two 500 air watt motors!

You'll want to choose a machine with more power if you have a lot of carpet in your home, a long hose, or if your plumbing configuration is different.

Most guides make the mistake of only considering air watts, which should only help you narrow down your choices. To choose the right vacuum cleaner for your needs, also consider data such as the water column, tank capacity or air outlet location (indoor or outdoor).

Central Vacuum With Or Without Bag?

Unless you choose the Automatik that empties directly into the sewer, you will have to choose a vacuum with or without a bag. Don't worry, you'll be happy with either option!

A bagged vacuum like the S1000 and Generation 2 series is beneficial if you suffer from allergies since you will never be in contact with the dust. A bagless vacuum cleaner has the advantage of being more ecological and you will not need to buy bags and you will save on the long term.

Which Vacuum Cleaner Should I Choose If I Have Pets?

Not all central vacuums are effective at removing pet hair. If you have pets at home, it’s suggested that you choose a powerful model with a large capacity canister or a bag to facilitate emptying the unit.


Noise is an attribute not to be underestimated when choosing a vacuum cleaner, especially if you live in a small home or condo. Some small stores allow you to test the noise level of the appliances. You can also rely on the number of decibels, the appliances that emit the least noise are around 60 dB. Finally, it is possible to add a silencer to your central vacuum system.

Investing in the right central vacuum system is an important choice, so it is important to choose a device that will last a long time. Do not hesitate to contact us if you have any questions!
