Agree with Joe.
I've got the CFR spotter with hand tool, you can get a floor wand for it but wouldn't use it to do a large area.
I offer stain removal at a much cheaper rate that my minimum call out charge using the spotter and had good response from it. Ideal situation was just yesterday, stain in a flat 3rd floor, all I had to take was the spotter, brush & a couple of sprays, 15 minutes later walked out with a happy customer and £30 in my back pocket.
Also use it to demonstrate cleaning techniques to secure jobs.
Handy tool to have if your getting getting it cheap.
