Two terms account for most of the confusion around Riccar upright vacuum cleaners: Clean Air and Tandem Air. They might sound like marketing language, but they name two different machine architectures, and the difference reaches further than performance.

The two platforms take different bags and different filters. An R27 owner and a Radiance owner are shopping for entirely different part numbers, so identifying which platform you have is the first step toward ordering the right Riccar replacement parts, whether that’s R27 vacuum bags and filters or something from the Tandem Air side.

Three Technologies, Not Two

Clean Air and Tandem Air make more sense with a third term in the mix, because Tandem Air is built out of the other two. Riccar’s own framing is that most vacuums use either a clean air motor or a direct air motor, and each one does something the other can’t.

The easiest way to tell them apart is to follow the dirt.

Clean Air

Dirt comes off the carpet, travels up the airway, and lands in the bag. The air keeps going, through the bag media, through the filters, and only then through the motor on its way out of the machine. The motor never sees anything but clean air. That’s where the name comes from.

That arrangement does two things well. Filtration is excellent, because every particle the machine picks up has to pass through the media before it can go anywhere else. And hose suction is strong, because the entire airflow path is built around pulling through an opening, which is exactly what an attachment is. Riccar steers allergy households and homes with mixed flooring toward these machines for both reasons.

Direct Air

Now move the motor down near the floor and put the fan directly in the dirt’s path.

In a direct air machine, debris passes through the fan on its way to the bag. That buys you the shortest possible route from carpet to bag, with the fan itself helping to lift whatever the brush roll has loosened. There’s no long airway working against you, so the machine pulls hard right where the carpet is.

The cost shows up above the floor. The airflow is engineered around the nozzle rather than a hose, so tool suction is limited. These also tend to be lighter machines, with the suction dedicated to the floor.

Tandem Air

Tandem Air puts both motors in the same vacuum and lets each one do what it’s good at.

A direct air motor sits down at the floor and handles carpet. A separate clean air motor handles suction, the hose, and filtration. A control shifts the machine between the two jobs, so the carpet gets the fan and the attachments get the pull, and both paths end at the same bag. Riccar calls the arrangement exclusive to its own machines, and Tandem Air uprights carry the Carpet and Rug Institute’s Gold Seal of Approval (the carpet industry’s scientific program to test effectiveness of carpet cleaning products/equipment).

Why Tandem Air Filter Sets Contain a Third Filter

The second motor isn’t visible from outside the machine, but it leaves a clear signature in the parts list.

A Clean Air filter set contains two filters: a granulated charcoal secondary filter and a pleated HEPA media post-filter. That is the full complement for a single-motor machine.

A Tandem Air filter set contains three. Riccar’s own description of the Radiance R40 filter set lists a pleated HEPA media filter, a granulated charcoal filter, and a direct air motor filter. That third component exists because there is a second motor in the machine that needs its own protection.

Which Riccar Uprights Use Which

The two platforms sit at different points in the range, and the model numbering follows a pattern once you know it.

Clean Air covers the R25 and R27 upright families along with the Simplicity S27 equivalents. Tandem Air covers the Brilliance R30 and Radiance R40 uprights, and Riccar also builds it into select models of the Prima canister line.

Riccar builds other lines that sit outside this comparison, including their lightweight upright vacuums (SupraLite) and the R65 cordless stick vacuum, and those carry their own bag and filter parts.

Bags and Filters Do Not Cross Between Platforms

The two platforms use different bag housings and different filter configurations, so parts don’t interchange between them.

Within the Clean Air family the parts consolidate nicely, which is why one bag and one filter set covers six machines across two generations. The Tandem Air side is more segmented, with the R30 and R40 series each taking their own parts.

Bag and filter part numbers are printed in the owner’s manual for each machine, and the model number is on the plate. If the manual is long gone, the model number alone is enough for a dealer to identify the correct parts.

A Note on Older Radiance Models

The Radiance name has been used across more than one generation, and the parts changed along the way. The older RAD and RADP models take a different filter set than the R40 and R40P, so “Radiance” on the housing does not settle the question on its own.

Working from the model number rather than the series name clears it up every time.

Which Platform Suits Which Home

Riccar publishes guidance on this, and it follows directly from how each platform is built.

Clean Air is pointed at households with allergies or pets, at homes with mixed flooring, and at anyone who uses the hose and attachments regularly, since tool suction is a strength of the design. Direct air machines are described as suiting homes with wall-to-wall carpet and little need for attachments, with the benefit of lighter weight.

Tandem Air is aimed at the household that wants both: significant carpet alongside bare floors, plus attachment performance and filtration. It’s the most capable of the three, and the largest, with an extra filter to keep up with.

For a household already running a Clean Air upright, the question usually comes down to carpet. If deep pile is where the machine feels like it’s working hardest, that’s the gap the direct air motor is built to close.

Making Sense of the Model Names

Riccar has used two naming conventions in parallel, which accounts for most of the mix-ups buyers run into.

The series names, Radiance and Brilliance, appear in parts catalogs and on older listings. The current product naming describes the technology and the tier instead, so the same machines appear as the Tandem Air Deluxe and the Tandem Air Premium Pet. A shopper comparing a Brilliance R30D against a Tandem Air Deluxe may be comparing one machine to itself.

The Clean Air side has its own version of this. There is no Riccar-badged standard model in the current R27 generation, so the entry point into that platform carries Simplicity branding as the S27S. Simplicity and Riccar are sister brands on shared engineering, which is why the parts overlap.

Frequently Asked Questions (FAQ)

Q: What is the difference between Riccar Clean Air and Tandem Air?

A: Clean Air machines use a single motor, with air drawn through the bag and filters before reaching it. That produces strong filtration and strong tool suction. Tandem Air machines use two motors, pairing a direct air motor that drives carpet cleaning at the floor with a clean air motor that handles suction and the tool path. Tandem Air is the more capable platform on carpet; Clean Air is lighter, simpler, and takes fewer parts.

Q: Can I use R27 bags in a Radiance or Brilliance?

A: No. The Clean Air and Tandem Air platforms use different bag housings and different part numbers. R27HC-6 bags fit the Clean Air R25, R27, and S27 uprights. The Brilliance R30 takes RNH-6 or RNHC-6, and the Radiance R40 takes RPH-6 or RPHC-6. Filter sets differ as well.

Q: How do I tell which platform my vacuum is?

A: The model number on the plate is the reliable answer. R25, R27, and S27 machines are Clean Air. R30 and R40 machines are Tandem Air.

The filter count is a useful secondary check. Two filters indicates Clean Air, while three, including a small motor filter, indicates Tandem Air.

Q: Should I choose Tandem Air over Clean Air?

A: It depends on the flooring. A home with significant carpet, particularly thicker pile, is where the direct air motor earns its place, and Riccar positions Tandem Air for households that want carpet performance without giving up attachment suction and filtration.

A home that is mostly hard flooring with area rugs is less likely to notice the difference, and the Clean Air platform is lighter and simpler to maintain.

Q: Do both platforms use HEPA filtration?

A: Yes. Both use self-sealing HEPA media bags meeting the 99.97% at 0.3 microns standard, along with charcoal filtration for odors. The difference is the number of stages and the presence of the direct air motor filter on Tandem Air machines.

Q: How often should the bag be changed?

A: Riccar’s guidance in the owner’s manual is to change the bag monthly, or once it reaches two-thirds full, whichever comes first. Households with pets and heavy carpet will reach that point sooner. Riccar also recommends having the machine checked annually by an authorized retailer.
