Portable air duct cleaning system and method of use

Abstract

A portable air duct cleaning system comprises a cleaning assembly, including a hose, motor and brush; portable power and control box; and remote control. The cleaning assembly may include a vacuum system connected to the hose, having an opening, with a motor driven brush unit positioned near the opening for vacuuming particulate matter dislodged by the brush unit while the brush unit traverses the air duct. The vacuum system may be part of a carpet cleaning system.

1 . An air duct cleaning system comprising:
 a rotatable brush unit connected to a brush motor configured to drive said brush unit;   a power box comprising:
 a control board; 
 a power source; 
 a vacuum power plug receptacle; and 
 brush power plug receptacle; 
   a hose having a first and second end, said rotatable brush unit positioned adjacent to said first end of said hose and powered by a power cord extending from said power box to said brush motor through said hose, said second end of said hose attachable to a vacuum source configured to draw particulate matter dislodged by said brush unit from an air duct into said hose and to a particulate container remote from a said air duct.   
     
     
         2 . The system of  claim 1  further comprising a remote control unit configured to control the brush motor via a receiver integrated in said power box. 
     
     
         3 . The system of  claim 2  further comprising means for attaching said remote control to said power box. 
     
     
         4 . The system of  claim 1  wherein said vacuum source is truck-mounted. 
     
     
         5 . The system of  claim 1  further comprising a flexible member which connects said brush motor and brush unit to said hose. 
     
     
         6 . The system of  claim 5  further comprising a cuff mounted to said first end of said hose, said flexible member connected to said cuff. 
     
     
         7 . The system of  claim 1  further comprising a waterproof box configured to contain said power source. 
     
     
         8 . A system for cleaning an air duct comprising:
 a brush unit, having multiple self-adjusting brushes, and brush motor formed of a single unit, said brush motor configured to drive said brush unit;   a power source contained within a housing, said power source adapted to power said brush unit and a vacuum source;   a power control board contained within said housing and including a vacuum power plug receptacle and brush power plug receptacle;   a hose to which said brush unit and brush motor is connected, said brush unit and brush motor connected to a hose cuff at a first hose end using a flexible connector; and   a power cord extending from said power box to said brush motor through said hose, said second end of said hose attachable to a vacuum source configured to draw particulate matter dislodged by said brush unit from an air duct into said hose and to a particulate container remote from a said air duct.   
     
     
         9 . The system of  claim 8  further comprising a remote control unit configured to control the brush motor via a receiver integrated within said power source housing. 
     
     
         10 . The system of  claim 9  further comprising means for attaching said remote control to said power control board. 
     
     
         11 . The system of  claim 8  wherein said vacuum source is truck-mounted. 
     
     
         12 . The system of  claim 8  wherein said flexible connector is flexible steel.
