Follow These Rules When Buying a Central Unit
There are dozens of companies that make central vacuum units. It would take way too long to research all of them, so use these four guidelines as a shortcut. If you just want the rules without all the details, here’s a quick list for you. The next section will give you more details.
1 Go With One of the Bigger Manufacturing Companies
2 Don’t Get Caught Up in the Numbers
3 Know What You’re Getting Into with Maintenance
4 Always Choose High Quality over Saving a Little Money
1. Go With One of the Bigger Manufacturing Companies
This is important, huge even. A central vacuum unit is an investment in your home, so make sure to buy from a bigger company. Some of the smaller companies aren’t much more than a couple of guys in their garage. You just don’t know what kind of service to expect with them.
With big companies like Beam, VacuMaid, and Vacuflo, you know what you’re getting. These manufacturers have good reputations and solid products. Their central vacuum units have good serviceability and support, so go with one of these.
2. Don’t Get Caught Up in The Numbers
Unless you’re an engineer or a glutton for punishment, don’t pay a whole lot of attention to all the numbers. These central units have a ton of specs they want to talk about, but they won’t mean much to the average buyer.
The only number you really have to check out is square footage. Central units have a maximum square footage they can cover, and you don’t want to buy one that’s too small. You’ll lose too much suction power if you do. We recommend that you cut manufacturer's "up to" recommendations in half. In other words, if a manufacturer says that a unit is good for "up to" 10,000 sq ft of living space, you should expect it to work very well in your 5,000 sq ft home. This is a general rule used by many central vacuum installers.
Like we said before, just double the square footage of your home and look for units that can cover it. You double it just to make sure you have enough suction for deep cleaning, even for the most remote parts of the house. Or in case you want to make additions to your home later on.
What about Air Flow and Water Lift?
You don’t need to worry about things like air flow (CFM) and water lift, not by themselves at least. These numbers only matter because they’re used to compute something called “air watts.”
Air watts measure how much power the central unit has. But for the average buyer, it’s just a good way to compare different brands. Like we said though, it’s not required.
3. Know What You’re Getting Into With Maintenance
Good maintenance is crucial to your central vacuum unit. Without it, you’ll encounter problems pretty quick. And with some companies, poor maintenance can void your warranty.
So know what you’re getting into up front. Ask yourself these questions about the units you’re interested in.
• How often do I need to empty the dirt receptacle?
• What’s involved in cleaning the filter? (hint: go with a self cleaning filter)
• How much dirty work’s involved in maintaining the unit?
• Do I need proprietary filters and bags?
Be honest with yourself. Don’t set yourself up for failure by committing to maintenance you won’t always be able to do. Spend a little bit more up front to get a low maintenance unit.
4. Always, Always, Always Go For High Quality over Saving a Little Money. Always.
We hope the message is clear. A vacuum system is an investment in your home. A good one can actually increase resale value a bit. So be willing to spend a couple hundred dollars more to get a high quality power unit.
Here are a few central vacuum units for comparison.
• The Beam Serenity 398A
• The Vacuflo FC1550
• The VacuMaid S2600
These are high quality models, in terms of performance and serviceability both. They’re absolutely worth the extra money you pay up front. The first service call will eat up whatever you save on a cheaper model anyway.
Lastly, you’re just going to get better longevity performance and service when you buy a higher quality vacuum unit. We can’t emphasize enough how important quality is.
Get the Right Filtration System
After the motor, the filtration system is the most important part of your central unit. Broadly speaking, there’s three different types: bag units, filtered, and cyclonic. Each type has its own set of pros and cons, which we’ll discuss below.
1. Bagged Units
Bagged units are about like they sound. They use a bag to gather debris, just like your old fashioned portable vacuum cleaner. It’s best to empty them when they’re less than ¾ full, otherwise you’ll lose suction power.
Although outside venting is alway an option, one advantage of bag units is that they don’t absolutely require it.
2. Filtered Units
Filtered units use a filter to protect the motor from getting clogged with dust and debris. They may or may not use a bag, depending on the manufacturer. And just like a bag unit, outside venting is not required. The downside is that the filter inevitably reduces air flow and suction power.
You have to clean the filter, to ensure efficiency and better protect the motor. This can sometimes be a dirty job. This is one of the reasons we like BEAM vacuum units, because they have a self cleaning filter.
In our opinion, filtered units are the way to go. The offer the best combination of efficiency and ease of use, especially the self cleaning variety.
3. Cyclonic Units
Cyclonic units work by spinning the dust and debris around at incredibly high speeds. The heavier dirt stays in the canister, while the rest is either exhausted outside the home or sticks to a screen which needs to be cleaned. This means that outside venting is always required. There’s no filter to clean in cyclonic systems, so you’re virtually guaranteed to get 100% cleaning power, at least initially.
It’s our experience that the lack of a filter is a real drawback, even if it does give you maximum power, initially. But without a proper filter, dust and debris inevitably get into the motor over time, greatly reducing suction power. This almost guarantees service calls down the road.
So there you have it – the ultimate buying guide to buying a central unit on the web. We’ve given you the most essential information, but you can always research individual brands if you want more. With this buying guide, you’ll know exactly what to compare and how to evaluate your options. Good luck!
