Personally i would recommend hiring a high powered carpet cleaner (or paying a professional carpet cleaner) ruther then buying a domestic one (VAX etc).

Most modern carpets are NOT designed to bee washed (only spot cleaned). Household carpet cleaners (even the quite expensive ones) dont dry the carpets as well as is nessary which leads to "delamination" (where the seconday backing (felt or faux hessian) seperates from the pile weeking the carpet from were and causes ireparable bubbling).

The problem is carpet cleaners are designed for "proper" carpets as in REAL hessian (almost none-existant nowa days)or rear weve carpets (axminster/wiltons etc) and not the modern cheap (and not so cheap) and chearfull carpets.

As a carpetfitter/flooring inspector i regullary see these issues in peoples carpets and see how upset they get when i tell them there is no fault with the carpet but the cause of the problem is them getting the carpet too wet.
