Citation regarding performance of Rental machines
The article says: "DIY and rental machines use some of the technology from the professional systems, but with less power and without the power to heat water (filling the unit with hot water is advised) the results are limited, these units are not typically called HWE systems.[1]"

The cited reference [1] links to the website of a professional carpet cleaning service which may not have a non-biased position regarding the performance of rental machines. Chaywesley (talk) 02:30, 8 November 2012 (UTC)
