There is an ongoing debate among homeowners as to which carpet type to use: hand knotted or hand tufted. Basically they both look pretty much alike, however there are some basic differences between the two particularly when it comes to the way they are produced. The hand tufted carpets are also known as Full cut or latex carpets, and making them don't require any particular skill, unlike knotted carpets which take much longer to make and need some knowledge in getting the knots lying the right way.
When making a hand-tufted carpeting, you need to use good quality wool material. On the other hand the quality of the hand-knotted rug is mostly based on how many knots are available per square inch. Many people call the hand tufted types as disposable as they seem to be the lower cost ones that don't need much labor and expertise in doing them. This means that they are cheaper when bought so they are a better alternative when budget is your biggest motivator.
If the tufted rug is made of low quality wool, it won't make a good quality piece in the long run and it will start showing signs of wear really fast. Getting a good quality piece means that you will have to shop around and buy it from a company with a good reputation.
There is a third type of rug that can be also used for your carpeting, called flat woven rug. This is quite lightweight and very easy to look after and clean. You can see many of these items as show pieces that are hung mostly on the walls than laid on the floor. You won't find knots on this type and this makes it a much easier construction than the previous two types.
To properly care for your staircases the best option is to use wood stair treads, while for areas around your staircases where a full fledged carpet cannot fit you can easily go with some beautiful well placed braided stair treads.
