Using an online inflation calculator, the £90 price of this cleaner today would have been £55 in 1997. So, that's well over 100% cheaper in price, when your original cleaner retailed for £130 in 1997. Despite the massive price change, the new Pure Power has nowhere near 100% less quality (it wouldn't exist if it contained 100% less parts). So to me it's a real bargain in those terms.
As the original cleaner retailed for £130 in 1997, that makes it a whopping £213 today.
So, question is, you paid half the price, do you feel you got more than half the cleaner you had already?
