I have experience with long hair. However, there is probably not as much long hair as with cats. There is a special attachment for the hair. Some of the hair is already "clumped" in this attachment. However, there are always some hairs that are pulled upwards lengthwise. These are then also wrapped around lengthways as they are pulled in. This is then a fiddly job to remove. But it's not too bad. Usually all the hair comes out at the same time. If there is a lot of hair, the container may be a little small with this model.
