We have grandkids and kids that love to wipe their hands on furniture. The arms get the grungiest!! I knew this would be the first test zone. I love the fact I can spray the cleaner and easily remove the brush and gently scrub with the handy brush and wow the yuck it pulled up. With one treatment the arms look so much better. I think two treatments and they would look brand new!! WOW I was so surprise at how well this little machine charged up thanks to the lithium battery and I am on to the upstairs where There is a pet stain I have my eye on! Then I will go to the car and clean the upholstery where the grandkids ride in their car seats and drop food. Can't wait to see how this little mighty max cleans. I do not think it will let me down. So easy to put together and operate and clean. Thank you Bissell!
