Although they are a lot heavier than most wands, the roller makes them very
easy to move. If you have a particularly bad patch of carpet you can spray on
the forward and back stroke. On large areas you can easily wand one handed.
And unlike glides on a conventional wand which actually reduce suction by
allowing more air into the end of the wand by lifting it slightly, The Wonderwand
maintains a very good seal on the carpet being cleaned.
With this wand you can clean at 500Psi without any fear of over wetting, obviously
it's rare to need it, but very handy to have.
