Bought replacement parts from another vendor, but the brushes are nylon and do not last. Filters did not fit 11S, so I had to throw them away. Parts from this current kit fit perfect, brushes are rubber and seem more sturdy. Have not had to change them yet, but there were 10 replacement brushes in the kit, as the other kit only provided 4. Changed the filter also, picks up a lot more dust and dirt.
