I have one cat with colitis and another one who sometimes eats too much too quickly so throws up. I have a full size carpet shampooer and a Pet Pro Spot Clean but for a small spot the Power Brush Portable is perfect. I use the other two when I need to clean multiple spots or a large area but for a small spot they're like using a fire hose to put out a match. The carpet/stain cleaner that comes with unit works extremely well and doesn't leave the sticky residue resolve does. It's relatively easy to take apart and clean. The You Tube video was very helpful.
