With a rotory on a lower RPM setting, then max, would do a good cleaning too.Yes, after running them for 2 years, here's what I have learned. If you take advantage of the high flow capability, you don't need high pressure or high heat and hot tap water is absolutely fine. Same BTU's delivered to the floor at 1.75 gpm @ 130° as 1 gpm @ 210°. Better cleaning, faster with less wanding.

You couldn't give me a brand spanking new 5 amp, 35 pound (plus hardware), 140° tolerant, fussy, high pressure pump for a true portable anymore.
High flow with using a wand and good vac pick up, using portable, it is what I found to be very good deep cleaning and fast.
