With an adjustable length up to 36", the WonderWand will go under, behind and over those heavy, hard-to-move objects. Even narrow spaces can now be reached. All those nooks and crannies and hard to reach places will never be dusty again. Cleaning tip comes with attached magnets to allow pickup of metal objects. There needs to be 3/4 of an inch of space for the width of the wand. Use with any standard 1.25" diameter vacuum hose or wand.
