The Numatic George is one of the most versatile machines you could ever own for your home.
First of all there is the standard vacuum function, this is pretty much the same as a Henry but with a larger capacity, the suction is very good and combined with a turbo head will give exceptional results on carpets with pets in the household. The use of Hepa flo bags will bring it up to full Hepa spec like those gimmicky bagless types, but cleaner for those with allergies.
The carpet shampoo function of this unit is excellent, I actually own the professional CT470 version of this which is the shampoo only professional machine, and use it frequently for my clients carpets in my cleaning business. When used with a good quality chemical (prochem extraction pro) great results can be achieved, better so than the orange vax units (which my folks own) which are lesser powered. The shampoo accessories are very nice and spray control is given by a handy trigger valve, unlike the orange vax (sorry but i bet you're looking at that unit too) the system seems to be purposely built and doesn't have slack solution hose when using the upholstery attachment.
Overall this is a great quality unit for the home from a respected and well recognised brand and is British built warrantied for 2 years. Honestly im not a salesman for Numatic but this unit really is best in class and is pretty much a great professional product which will fill your every day cleaning needs.
