This great little carpet spotter by Sandia comes with it's own internal heater. Add to that a generous 15 foot solution/vacuum hose and a 4" stainless steel upholstery tool and you have a set up to do some powerful spot removal just about anywhere.
If you don't need a spotter with its own heater then you may want to consider the 3 Gallon Spotter with Tool by Sandia. However, it has an 8 foot hose and clear plastic tool. Make sure to look through all of our carpet spotters to find just the right one for you.
