The RV360 has been out in the UK for about 2 years now. In the US about 4 maybe 5 years.
Early ones had a problem in the UK, the latest model is revamped and hopefully should be OK.
A few c/cleaners have them and love them, one or two sent theirs back, but these might have been the problomatic early ones.
If you just starting in c/cleaning then I would spend the money on other things - you can do a very good job with a wand, and £2000 to replace a wand is a lot of money when it could be invested elsewhere in the business ie marketing or a better machine.
Have you been on you tube and searched for Rotovac 360 - one or two good viedo clips.
