Wobbles,
my old man was in the army and everytime we moved home (14 times in 10 years) the carpets had to be done (you know to ispection standards, blah blah blah... Sir! yes sir!)
Anyway, my old dear swore by Vax and I never saw her use anyhting different. I even think she had the same model for around a decade... how reliable is that....
