We recommend that you have a yearly clean of all carpets. Why? I hear you ask!! Here are some of the reasons: 1. 70% of all household dirt and dust consist of dry flakes of dead skin and this handsome just loves to feed on this. (click here) 2. Your home becomes more hygienic and comfortable to live in. 3. Smells fresher for longer and reduces household smells. 4. Increase the life expectancy of your carpets and upholstery including their appearance. 5. If you suffer from allergies then symptoms will be reduced. We believe our system takes away the worry of you having to remember to keep your carpets hygienically clean and looking like they did when you first had them laid. Because vacuuming daily or weekly just is not enough to keep them really clean; thats like having a hard floor and just sweeping it for a year without ever washing it. Just think how it would look at the end of 365 days of dirty shoes and dogs; paws walking all over it and we have'nt even thought of all the spilled drinks and dropped food.
