Duct Cleaning Summary

 *

 

 
1.

 

Before using the COBRA VI to clean the air system, the supply and return duct diffuser grills must be 
removed.  Also, pre-vacuum and plug these openings, and then attach the Turbojet or other negative 
air machine to the system. If the Return has a Filter, Remove the filter, place it in a Plastic bag and 
reinstall the filter into the return to block air flow through the air system during cleaning.  Do not 
forget to remove this bag when the job is complete. 

2.

 

CAUTION: 

DO NOT INSERT OR REMOVE THE BRUSH FROM THE DUCT WHILE THE 

BRUSH IS TURNING 

3.

 

Begin at the duct opening farthest from the furnace/air conditioner.  

4.

 

With the Brush STOPPED, insert the brush and cable assembly one or two feet into the duct to be 
cleaned.  THE MACHINE END OF THE CABLE MUST  BE STRAIGHT FOR AT LEAST 4 to 5 
FEET TO REDUCE THE FRICTION and HEATING OF THE CABLE HOUSING.  A tight bend in 
the cable will cause friction that will damage the cable housing and cable resulting in costly repairs or 
replacement of the cable. 

5.

 

Start the brush by turning on the main power, press the START switch on the Remote and it will start 
in the lowest speed. The brush will begin to rotate within a few seconds.  

 
NOTE:

 The brush will begin to turn slowly in the Lowest Speed setting.  Most duct cleaning will 

be done between 2 and 3 of the 4 speeds.  

 
6.

 

Push the Flex-E-Bristle Brush into the duct with a smooth gentle force.  The brush will expand and 
compress to clean any size duct from 4” to 18” high and any width.   

 
CAUTION: 

To clean duct board ducts, or older flex duct systems, the COBRA VI Brush system 

should be used at a lower  speeds (1 or 2)  with caution as its aggressive cleaning action may 
damage these delicate ducts.  Internally insulated ducts, brittle flex ducts and fraying duct board 
ducts should NOT be cleaned with a power brush.  
(See Forward and Reverse Air Whisk and Sidewinder, on

 ) 

 
7.

 

When the end of the duct is reached, the cable can be pulled slowly back toward the opening.  If the 
duct is rectangular in shape, Press the “Change Rotation” on the Remote. The rotation of the brush in 
this direction will allow it to “Walk” to the opposite side of the duct from what was cleaned going into 
the duct and assure that both sides of the rectangular duct are cleaned. 

8.

 

Stop the brush 1 or 2 feet from the duct entrance then remove the brush.  This duct opening can now 
be plugged with the foam plug, and the next duct opening cleaned in the same manner.  Repeat this on 
each duct opening until all have been cleaned. 

9.

 

The duct system is now ready to be decontaminated by fogging in a duct sealant like Soot Set and an 
EPA registered sanitizer such as Envirocon.
