I first used kiwi July 2012 when my roommate was moving out and our carpets needed to be cleaned before the my new tenant moved in. They started out filthy and looked brand new after kiwi. They have a 1 year warranty so over the year we had the carpets cleaned about 4 times at very minimal cost (I think it's around $28 to have them come out + $4/room or staircase). Now my lease is up at the end of this July and I had to get them cleaned a final time before moving out. I wanted them cleaned about a week past my 1 year warranty date and I spoke with a rep who said it would be no problem to extend it by a week. Great service, great price. Highly recommended!
