We had Stanley Steemers clean our carpet a few days ago. The house has beige carpet throughout from the mid-70's! Sad but true.
I called them because over the years we had used their services in other homes we've lived in many times..
They arrived on time in the morning and were finished in an hour. We didn't move any furniture, just had them do as much as they could around the sofa and chairs, etc.
(They did move the dining room chairs and were able to do that room efficently.
I'm 100% satisfied. The carpet dried in practically less than two days. The event was 'non-intrusive' and not noisey.
ps, They do need a water hose source but they used the outside faucet.
