I've been using Sweep Home Chicago for several months and have always had a positive experience. The cleaning staff is always punctual, professional, and courteous, and they do a great job. A few times I've made a specific request and they always remember (i.e. I didn't want any dusting cleaning product used in my baby's room, just a damp cloth). The customer service is excellent. If you have any questions or concerns, they attend to it right away.
