I have a kirby vacuum cleaner with a shampoo attatchment. I love it because it dries quickly! I had a bissell steam cleaner that I LOVED until the motor went out in it...I plan on getting another one soon!!!
I usually make my own shampoo...much cheaper than what you buy!!!
1 cup laundry soap (liquid)
1 cup fabric softner (liquid)
1/2 cup household ammonia
added to ONE GALLON hot water
I only use the ammonia when I am dealing with HEAVY staining...otherwise I just use the laundry stuff! Smells wonderful, carpets are soft, and you can pick your own scent!!!! If you are worried about baby...I would try it with the baby safe laundry soap/softner!!! Couldn't hurt!!!
I hope this helps!!! BTW-I haven't found a machine yet (kirby, rented, bought steam cleaner) that this mix doesn't work in :)
hugs and brightest of blessings
