You are ignoring the advice given on here again.

David, you are correct - you dont need 600psi to clean a carpet, mostly I keep at 400 but could easily do the job at 300. Use the Rotovac 360i and you can go really low - 200psi or maybe even less.
The wand "sticking" to the carpet though is not caused by the solution pressure, as you probably know.
