We use the Lint Eater that can be purchased at most any Lowe's http://www.lowes.com...ge=1&facetInfo=
Also, we used Chimney cleaning rods (harder stiffer and bigger) attached between the drill and Lint Eater, with custom made connector, for the straight portion of the dryer run. The down fall, you can't go around any bends with them. Also, you risk breaking off the Lint Eater portion by pushing against a 90 degree turn...
Most cleaning events are done within 15-30 mins. We don't do just dryer vents. Must have us out working on the dryer first. That way we get to pick and choose which vents get attention, from us.
