Hello, I was wondering if this Sebo head would work on a central vac with 2 prongs. I used a Sebo Head @ the Vac shop but I'm not a 100% sure this would work. The only reason I question this is because I heard that in the UK it's different. Also, I was told that the hard bristles could tear berber carpet. Is this true because I have 90% berber. Thanks! Clayton
