Rotary Brush Air Duct Cleaning Equipment - Comparison & Review
If you are looking to buy air duct cleaning equipment, the rotary brush air duct cleaning equipment method is one of the most popular methods of cleaning air ducts in the residential and light commercial marketplace. The “rotary brush” option is what duct cleaning professionals choose, because brushes provide a “uniform” method of scrubbing ductwork vs. air whips and other agitation forms. However, as you will see, not all rotary brush air duct cleaning equipment cleans the same.
Brush Connected to Vacuum Hose
Many “rotary brush” type air duct cleaning equipment systems out there are basically a vacuum with a brush connected to the end of the vacuum hose. A cable runs inside the vacuum hose to allow the brush to rotate and scrub the duct. A couple questions should come to mind when you see this type of rotary brush equipment:
1)How will a brush connected to the vacuum hose be able to maneuver through the twists and turns of ductwork? The salesperson will basically try to convince you of “magic” and state that the system can just make the turns. However, logic defies this… Ductwork in homes have multiple twists and turns. This type of rotary air duct cleaning equipment cannot make theses turns, and you end up only cleaning SOME of the ductwork, because you cannot reach the end of the ductwork.
2)If the cable is inside the vacuum hose, will the vacuum hose get clogged easily? Not only is there wind resistance when you have a cable in a vacuum hose, but yes, dirt & debris will constantly clog the vacuum hose and cause vacuum problems and even cable breakages. Constant repairs will mean downtime. Time is money!
Brush Separate from Vacuum Hose
As you can see, there are too many faults with brush-vacuum hose combination type of duct cleaning equipment. When choosing rotary brush air duct cleaning equipment, you will want to choose a system that separates the brush from the vacuum hose. A cable system with brush separate from the vacuum hose will allow maneuverability through the ductwork. A system like the SpinVax 1000XT separates the brush/cable from the vacuum hose to allow much better maneuverability and eliminates the problems you see with combo systems.
Brush Types
Another difference in rotary brush air duct cleaning equipment is the type of brush used. Whether the brush is connected to a vacuum hose or on a separate cable, you want to look how the brush operates. Basically, here are different types of brush heads:
1)Round Brush – Most systems out there have standard round “puffy” brushes. They may offer multiple sizes (ie. 8in, 12in, etc). However, ductwork changes shape & size throughout the home. You may start at an 8in opening, but the ductwork expands to 12in round or even a rectangular duct that might be 8in x 16in. How is an 8in round brush cleaning the expanded duct or the rectangular duct very well?
2)Brush “Twigs” – Some brushes out there might look like they try to “adapt” to the size of the duct because they have a stem with “twigs” of bristle coming out of the stem. However, the speed of spin is what opens the brush. If the brush is only spinning at a couple hundred RPM, the brush will not open properly. Also, there is no “angle” to the brush twigs, meaning that they are just throwing dirt in all directions.
3)SpinVax 1000XT Reverse Angled Brush Strips – The SpinVax 1000XT Air Duct & Dryer Vent Cleaning Equipment uses a proprietary brush system called “FlexTend” that has precision “angled” brush strips that spin at 1000 RPM to automatically open up and adjust to the duct size. Even more, the reverse pitched brush strips actually “reverse sweep” the dirt and debris back to the vacuum hose. Other rotary brush air duct cleaning equipment cannot do the “Automatic Duct Size Adjustments” and the “Reverse Sweeping Action.” This well engineered brush system can properly clean both metal and flexible duct without the operator worrying about duct size adjustments.

Cleaning Both Air Ducts and Dryer Vents
Another point to think about is related services. Many air duct cleaning customers will also want their dryer vent ducts cleaned as well. If you can’t maneuver your duct cleaning system through regular air ducts, how are you going to be able to maneuver through even smaller dryer vent ductwork? Why buy separate equipment? The SpinVax 1000XT system can clean both air ducts and dryer vent ductwork.
The Logic Choice
Whether you are a HVAC company, a cleaning company, or other business looking to add air duct cleaning, the rotary brush method is usually the best option. However, you want to think logically about choosing rotary brush air duct cleaning equipment. The SpinVax 1000XT provides better maneuverability through the ductwork, allows self-adjusting brush sizes to clean ductwork that changes shape & size, provides safe cleaning in both metal and flexible ductwork, and can reverse sweep the dirt and debris back to the vacuum hose for extraction. The SpinVax 1000XT is the logical choice for air duct cleaning equipment!
