While looking for a problem with my vacuum cleaner I noticed that this inner hose had snapped. After checking online (both Revain and YouTube) I saw that it was easy to replace and that this part is not expensive. The product arrived and after watching a YouTube video I replaced the hose. I noticed that the vacuum seemed to work a little better. Whether that's true or not, replacing a broken hose with this one was inexpensive and effortless. My 13 year old vacuum cleaner works perfectly.
