Edge/corner sweepers and filters work great but after a few uses the large roller brush didn't fit causing my vacuum to make a lot of clicking noises. I cleaned the vacuum completely thinking something was stuck somewhere but every time I restarted it the clicks got louder. I finally ordered a genuine part from a vacuum cleaner manufacturer and now I have no more problems. As I bought this large scooter as a fallback and didn't use it right away, I didn't think it was right to ask for a refund so late after I placed my order. I also use filters and mini brushes from this company and may reorder them.
