The Rosewill leads this price band on paper because it combines a 550W motor with 17 KPa suction and the largest tanks in the group. A 49 oz clean tank and a separate 53.6 oz dirty tank mean you can do a sofa or a staircase before stopping to empty. The dirty tank being larger than the clean one is a sensible design, since extracted water always exceeds what you sprayed.
Two caveats go with that headline. The motor wattage and the suction figure are listing claims, not measured results, so judge it as a well specified budget machine rather than a miracle. As a portable, a full bedroom is slow work compared with an upright.
Because this is a newer brand, keep the packaging and check the warranty terms. Rinse both tanks after each job and leave them open to dry, and wipe the nozzle seal weekly if you use it often. For a first extractor under the cap it is the most capable of the four, with a long enough run time to finish a typical sofa in one sitting. Because the two tanks are separate, you can swap the dirty one without disturbing the clean side, which keeps a staircase job moving. Test the first pass on a hidden edge so you know how wet the fabric is after one stroke.
