Can anybody out there tell me how the X-Terra 50 compares to the Quattro MP as to recovery time on trash items next to good items. I had a Quattro MP and it was just to slow of a machine for me. Great machine. I am just used to a faster paced machine. I am looking to trade for an X-Terra 50. And, want to know how it compares in this aspect. I am used to a faster sweep speed as with the White's and Fisher machines. Would I be getting a faster machine with the X-Terra 50? Thanks for our help!!
