All Carpets are cleaned using a Hot Water Wet Wash, using Pump Pressure of up to 200psi for top performance. The Ashby's Ninja provides a powerful vacuum strength of 230 inch water lift and 17 inch mercury lift. This is essential as the more powerful the vacuum the more effective the clean and combined, this assists in lifting the Carpet pile which may have been previously lost. Stains are pre-treated and most stains can be lifted within reason. We cannot do anything about general wear and tear on carpets or if the carpet is well worn - however we can still professionally clean these carpets for marked improvement.
