I've had the Sebo X4 vacuum for about 15 years! I haven't used it for years because it stinks and I haven't taken the time to clean it, change filters etc. I've been using Shark Navigator for a few years but have decided to go back to my Sebo. and run it again. This vacuum has actually gone up in price since I bought it 15 years ago! I replaced those parts, took out the brush and cleaned it, put the dryer in a new bag and voila! He's like new!
