I've had a Numatic Henry vacuum cleaner for years, so when my old carpet cleaner broke down beyond repair I was pleased to find that Numatic also make carpet cleaners. Delivery from ao was fast and efficient. I've only used the cleaner on the stairs so far, but it's solidly built and I love the simplicity of the design, making it easy to clean and maintain. Results are as good as my old cleaner, although it does leave the carpets slightly more damp.
