Query: ok

i bought this to replace an aging hoover steam cleaner and ultimately sent it back. it cleaned ok but it left a good 3/4 of the water it put down in the carpet. with my old hoover the carpets dried in 2 hours. with this one they were still wet 24 hours later. the water that came back up was dirty and the machine got some stains out, but overall left the carpet looking dingy. i was very disappointed.
