Are Central Vacuum Systems Worth It?

Yes. They are worth the investment due to their many benefits which we’ll take you through below.

Improved Air Quality

Central vacuum systems blow air and dust allergens into the outdoors through an exhaust outlet. This is unlike portable vacuum cleaners which recycle dust-laden air back into your household.

The Environmental Protection Agency states that regular cleaning can reduce dust mites, pollen, and other allergens. And whereas normal vacuuming can increase the airborne levels of these particles – “using central vacuum systems…may be of help” (1).

The Davis School of Medicine, University of California, did a study comparing the impact of a portable vs central vacuum on the quality of life in patients who suffered from allergens associated with house dust. The results showed that the symptoms of these individuals improved by up to 61% when they used a central vacuum system (2).

Powerful Suction & Durable

A central vacuum system gives you greater cleaning power because it has a large, powerful motor. The unit that contains the motor is installed in your home in a permanent spot (usually the basement). So it can take a bigger motor which gives a greater suction power.

Think about your traditional vacuum cleaners. These need to be carried around the house so can’t have as big a motor. Otherwise, they’d be too heavy. Central vacuums have a fixed unit and fixed tubing and so can have a better quality of motor, wiring, etc. They’re made to a higher standard with better materials.

A vacuum cleaner’s suction power is measured with air watts. These are calculated by looking at the CFM (cubic feet per minute that are covered) and water-lift at the end of the vacuum’s hose/tool/brush.

Compare this portable vacuum which is advertised as being really powerful – Dyson V15 – and has 230 air watts. But this OVO Central Vacuum System has 630 air watts, making it nearly 3 times more powerful.

A powerful suction means that you’ll pick up more dust, debris, and pet hair. This is especially true for households with lots of carpets. Tiny fibers and allergens can get ingrained in carpeted floors and most of the time a standard vacuum won’t suck these up.

Plus, a central vacuum system is durable as they’re built to last a long time. And because of this you usually get a longer warranty.

accordion_icon

Quiet

You won’t hear much noise from a central vacuum system because the noisiest part of it – the motor – is located outside the living space of your house.

A decibel output of 57 to 62 is considered low. And anything making this level of noise can be used at any time of day and shouldn’t disturb other people in your home or your neighbors.

On average, a normal conversation has a sound level of about 60 dB (3). And this OVO Central Vacuum System is very similar as the noise it produces is around 65 dB. But a typical portable vacuum cleaner produces a sound output of approximately 84 to 89 dB (4).

accordion_icon

Easy & Safe to Use

Using a central vacuum is quick and easy. As is storage – you only have the hose and any cleaning tools/brushes to find a space for (and not the bulkier body of the vacuum).

The main unit is housed in your basement or garage. So when vacuuming, you just need to put the hose into one of the wall inlets which are spaced throughout your house. And that’s all there is to it! Plus, cleaning your stairs is less challenging because you don’t have a big hot appliance to balance on the steps.

Central vacuums are safe because you won’t injure yourself carrying a heavy cleaner around your house. There are no electric cords for you to trip over or catch on your furniture. And there’s no bulky vacuum head that might bang into and damage table legs or couch feet.

accordion_icon

Large Dirt Collection

Central vacuum systems have large dirt canisters and/or large collection bags. They can take big quantities of dirt and debris before you need to empty them. So you won’t need to empty them as much as you would a standard vacuum. A few times a year is normally sufficient.

See, for example, this NuTone PurePower Central Vacuum System. The bags used in this model have a large capacity of 6 gallons. The manufacturer says that you only need to empty this on average every 6 months.

accordion_icon

Difficult Debris Collection

A central vacuum can collect and remove difficult debris more efficiently than a portable vacuum. This includes substances such as plaster dust, flour, laser printer toner, wire fragments from electrical work, and even tiny pieces of broken glass.

How well the central vacuum system collects this type of debris might depend on whether it’s bagged or not. Filter bags might get clogged or damaged collecting these substances. But bagless models can remove the biggest range of materials.

accordion_icon

More Value to Your Home

Many buyers will pay more for a house if it has a central vacuum system installed. This is according to Nick Gromicko, a Certified Master Inspector for homes (5).

The average cost of a system is around $1,200 to $3,000 for a house of no more than 3,000 square feet. This cost is not excessive and can be recovered easily when you go on to sell your house.

And because central vacuums last a long time, you’ll save money by not having to replace a standard vacuum cleaner every few years. So overall, they are a good investment.

accordion_icon

Low Maintenance

Central vacuum systems don’t require costly or everyday maintenance. Typically, you’ll need to empty the dirt canister or collection bag around 2 to 4 times a year.

You may need to replace the filter or the brushes on the motor, or lubricate the motor. But again, this is not something that you’ll be doing regularly. A central vacuum cleaner may become clogged. But this is rare.

How Does A Central Vacuum System Work?

A central vacuum system is a semi-permanent type of vacuum cleaner. The main body, which includes the motor and collection canister, is installed in a basement, garage, or utility space.

It’s designed with 3 parts:

Tubing, normally PVC pipes, are installed inside the walls of your home. Inlets are positioned inside walls throughout the house. You then insert a power hose or other vacuum tool into one of these inlets.

As you vacuum with the vacuum hose, dust is removed from your floors and furniture. It is pulled by the motor and sent through the piping network to the collection canister. Most hoses have a power switch on the handle so you can easily turn the central vac on and off.

This video gives you a good idea of how the system is set up and operates. It uses an industrial building, but the idea is the same for a home. Just on a smaller scale.

How To Choose The Best Central Vacuum System

Let’s have a look at the key features you should bear in mind when choosing a central vacuum cleaner.

accordion_icon

Suction Power

First, check how powerful the central vac is. This can be measured in different ways. Unfortunately, there’s no set standard agreed on by the industry.

One way you can measure is by air watts (AW). A powerful central vacuum will have a high air watt rating. Two examples are this OVO which has 700 AW. And this Nutone model has 550 AW.

But the power can be impacted by how far away the inlet is from the motor unit. The further away it is, the less suction power the vacuum cleaner will have. So if you’ve got a large home and the unit is in the basement, you’ll get less power on the top floor than on the bottom floor.

accordion_icon

Capacity

Look at the capacity of the dust bag or canister. This is how much dirt and debris it will hold. And the bigger the capacity, the less you’ll have to empty it, saving you time on maintenance.

Most central vacuum cleaners have large collection capacities. So compared to a traditional vacuum, you won’t need to empty them as much. But the capacity can vary by brand.

See, for example, this Allegro model which can take 5 gallons. Compared to this OVO system, which has an impressive 9.25 gallons capacity.

accordion_icon

Filtration System

There are different filtration systems to consider when investing in a central vac.

Cyclonic (Bagless)

These systems have no bags or filters that need replacing. Air spins in the collection canister and causes cyclonic separation. This is where 98% of debris and larger dirt particles fall into the canister. And the smaller dust particles are vented directly outdoors.

You need to think carefully about location if opting for this type of system. Dust-laden air could make its way back indoors if the unit is too close to windows/doors. And the filters also need cleaning every once in a while.

Filtered

Inverted bag, foam, or cartridge filters are housed in the dirt canister. Some filtered systems also take collection bags. These help to eliminate any debris that is not deposited in the canister by the filters.

This may not be the right choice for you if you suffer from allergies. Emptying the canister can be unpleasant and aggravate symptoms as mold and other allergens will become airborne.

Bagged

Dirt that is removed from your house is deposited into collection bags inside the canister. With this type of system, you don’t need an outdoor vent. But you might still want one as this can help to reduce noise and odors.

Bagged systems are a better pick if you have allergies or breathing difficulties. The dust is stored securely in the disposable bag and doesn’t escape. So when emptying your canister, you’ll not be as exposed to allergens.

accordion_icon

Installation

Consider how you want your central vacuum system to be installed. And how it can be installed depending on your home size and layout. There are two main types of installation methods you can choose from:

  • Standard Inlet
  • Hide-A-Hose Inlet (6).

A professional installer is probably a good idea. Because the central vac piping needs to run inside the walls of your house. And although it looks similar, the tubing is not the same as drain pipes!

You can also choose to have sweep inlets or basic inlets. And if you do decide to do the work yourself, note that most central vacuum cleaners need at least one inlet per floor of your home. Plus most floor plans require one inlet per 750 square feet.

accordion_icon

Attachments

Think about what accessories you want for your vacuum cleaner. Some come with a range; others don’t, but you can often buy extras. Here are the main attachments:

  • Crevice nozzles: long and thin, help you to suck up dirt from tight, awkward corners.
  • Elbow wands: connect directly to the inlet, help shorter people to reach spiderwebs on the ceiling and the top of tall curtains.
  • Wet nozzles: squeegee edge pulls liquid in and the nozzle sucks it into the system.
  • Brush attachments: upholstery tools such as upholstery nozzle for cleaning curtains and furniture, also good for the car.
  • Powered vacuum heads: connects to an upright tube that is attached to the vacuum hose, lets you vacuum as if you were using a standard vacuum.
  • Hose extensions: flexible or rigid, give you more length to reach all parts of your house, and can be retractable.
accordion_icon

Noise

First consider your house or condo, and how worried you are about the noise level of your central vacuum. As we said above, vacuum cleaners on average have a sound level of 84 to 89 dB.

Look for central vacuum systems that have a sound output of about 55 dB or below to avoid a lot of noise being created. Or find one that has the option for a quiet operation when you need it.

accordion_icon

Warranty

Check out what warranty comes with your central vacuum system. A good place to start is the manufacturer’s website. It’ll come in handy if you have any problems and want a replacement or refund.

Because of their durability, most of these systems come with generous warranties — between 5 to 10 years. But do examine exactly what they cover. Lots of brands protect against material or construction defects. But most will not cover you if you use your system incorrectly. Or general wear and tear.

How To Maintain Your Central Vacuum

Read on to discover how to maintain the different parts of your central vacuum system. Remember to turn the power unit off before you do any kind of maintenance.

accordion_icon

Canister

Check your canister at regular intervals to see whether it needs emptying or not.

If you have a bagged central vacuum system, the manufacturer might suggest how long it usually takes to fill up. And Prolux’s bagless model above has a window so you can see how full the canister is at any time.

NuTone’s recommendation for their 6-gallon dust pail is that the bag be changed or the canister be emptied around twice a year. This is under normal conditions and you’ll probably have noticed a reduction in suction power.

accordion_icon

Filters

Inspect these regularly, at least once a week. Or perhaps a little less depending on how much you use your vacuum system.

Filters should be replaced 2 to 4 times a year. But many models come with filters that are washable so these might last longer. Always replace a filter if you see signs of damage.

Filtered bags need to be changed when half to three-quarters full. If they get too full, the system can get clogged or you risk damaging the motor.

accordion_icon

Cyclonic Systems

These have a collection container that should be checked periodically.

But they don’t need emptying as often as bagged systems. You can normally wait until it’s full or you’ve seen the suction reduce.

accordion_icon

Motor

Check the motor and lubricate the bearings regularly to ensure it continues to function correctly.

Some models don’t need any oil – Imperium’s central vacuum has a motor with bearings that are greased and sealed for life.

accordion_icon

Brushes on Motor

These should last a long time so don’t need regular maintenance. The brushes will wear over time, but will only normally need to be replaced after 700 to 1,500 hours of use. That’s around 10 to 20 years!

But due to the damage that can be caused if they’re left to fully wear out, Imperium recommends that you have them inspected every 4 to 6 years.

accordion_icon

Tubing

You shouldn’t encounter many problems with the tubing. But another cause of loss in suction could be due to something sticky, such as glue, getting stuck here. This can normally be sorted with a plumber’s snake or piece of wire.

How Long Does A Central Vacuum System Last?

Many manufacturers of central vacuum systems say that they can last for around 30 to 40 years.

The design of the motors means that they can handle being used a lot longer than your traditional vacuum cleaners. Typically they’ll last for 800 to 1,100 hours of usage.

A 10-year cycle is equivalent to approximately 500 hours of vacuuming. So, the motor on central vacuums can last around 20 years.

But this is based on the motor. And these can be replaced and at a low cost. So the system as a whole – with a new motor at some point – can last longer.

By comparison, a Consumer Reports survey found that standard portable vacuum cleaners last for a median of 8 years (7).

Opt For A Spotless Home

It takes a lot of time and effort to clean your entire house with a standard portable vacuum. Especially if you’ve got a large area to cover. But with central vacuums, it doesn’t need to be such a chore.

A central vacuum system gives you powerful and easy cleaning. And it’s quiet and can even add value to your home. But you don’t need to worry about having to empty the bag or canister that often. Plus a central vac is quiet and good for allergy sufferers.

Check what suction power, noise output, and capacity the unit has before buying. And think about what type of filtration system and attachments you want. Our guide on the best central vacuum systems will help you compare these features on different models.
