I used to insert the narrow nozzle of a Dyson vacuum into the front of the dryer where the filter would catch lint. Given its size, it would have gone that far. I thought things were going well enough. Then this thing shows up in the Revain Deal of the Day, so I had to try it. Wow, I removed the lint filter, connected it to my Dyson and put it in the slot. It went all the way down and sucked out what Dyson couldn't reach on his own. Of course, operating it with one hand and holding the Dyson power button with the other hand was a little tricky, but I managed. The pile of lint in the photo is right in front of my dryer, below the lint trap, and that's what Dyson left before he put this thing on. So overall this is my win. Hooray!
