Product review (5 stars): No need to pay a contractor - this tool makes cleaning a dryer vent pipe easy and satisfying!
This is a great dryer vent pipe cleaning system!

Our dryer is in the middle of the second floor of the house, so there's a 24-foot pipe from the wall behind the dryer up into the ceiling and across the attic beams to the outdoor vent.  Hasn't been cleaned since buying the house brand new in late 2005!  Not being a fan of paying strangers to come into my home, I bought the LintEater 10-piece kit and a 12-foot extension rod pack.  The "chore" of cleaning the dryer vent pipe turned out to be a real joy because of this inexpensive and very effective tool!

Assembly is simple - screw the brush into the end of one of the flexible rods.  A little set screw and allen wrench are provided to ensure the brush stays on.

Turn your dryer on to the AIR Dry setting to blow unheated air out the vent pipe.  Go outdoors with your cordless drill set to turn forward/clockwise, attach the rod/brush assembly to the drill and rotate the brush/rod while pulling it in and out of the dryer vent pipe.  When lint stops blowing out - (You won't believe the clumps and quantity of lint this thing dislodges!) - screw another length of rod onto the end of the first rod, insert its end into the drill, make sure the drill will turn clockwise, and spin the lengthened assembly in and out of the dryer vent.  Repeat until all rods have been attached and lint stops blowing from the dryer vent as you pull the spinning brush assembly fully back out of the vent.

The ONLY thing one must remember in this extremely easy task is to always run the drill in forward/clockwise rotation because the rods will want to unscrew from one another if the drill is accidentally run in reverse. The instructions do offer the idea of putting duct tape around the rod connections after screwing them together to prevent disconnection inside the dryer vent pipe if you forget to only turn the drill in the clockwise direction.

As a do-it-yourself kind of guy, I'm willing to buy a tool if it can give me the ability to do a job myself whenever it's convenient for me rather than having to schedule some stranger to do something for me.  Rarely, however, does one find such an inexpensive and thorough tool as this!  This $40 kit (including the extra pack of extension rods I needed) made the job of cleaning my dryer vent pipe very satisfying and even fun!  It stores easily behind the dryer until the next time I'll need it.  (The instructions recommend cleaning the vent pipe every few months.)  The whole job only took half an hour from start to finish - including getting the ladder out of the garage and set up.  There is simply no reason to pay a contractor to do this easy task nor to forego keeping one's dryer vent clear of accumulated lint and the associated fire hazard that it creates.

  When ordering, measure how far your dryer is from the outside wall of your house where the dryer air is vented and add the vertical distance from the air outlet on the back of the dryer to the ceiling so that you know how many flexible rods you'll need in order to clean the whole thing from the outside.  If disconnecting the dryer from the wall pipe is convenient, one could even clean the pipe from the inside outward or from both ends.

My experience with the LintEater is unquestionably rated 5 stars. I would heartily recommend it to a friend.  It's inexpensive, easy to assemble and use, fast, does a thorough job, is almost impossible to goof up and small to store for future uses.  I will not go 6 years without cleaning my dryer vent again now that I have this kit on hand and will happily take it to friend's houses to share the benefits of a clean dryer vent with them.
