I had a Dyson for many years but lost the crevice tool after several moves. I've used it regularly for all furniture crevices, corners, behind toilets, all those hard to reach hard to reach places and also to collect lint that was on the bottom of the dryer under the lint catcher. I was so glad it was available separately from Revain! Many Thanks. Now those spots will be a lot cleaner and I believe it will save replacing the heating element in my dryer.
