I'm not sure that Sebo or Miele offers any sort of carpet cleaner. Sebo isn't easy to repair, but the benefit is that
Sebo NEVER breaks down. With a Sebo, you simply change bags and filters. If you want a cheaper, good quality vacuum i would recommend looking at
Sanitaire Vacuums. Sanitaire vacuums are very easy to maintain and repair when needed. Their commercial vacuums but can be used in the home. I dont think you can go wrong either way, just depends on what you want to spend.
