I bought a Groupon for here a year or so ago on two separate occasions for the same apartment.
The first time I took off work early to meet them and after waiting an hour after my appointment window I called and was told I wasn't on the schedule but they would get out the next day and they did.
A guy came out the next day said they would do their standard cleaning for the Groupon price but had a couple suggestions for upsells, one being a deep cleaning for an additional charge. I agreed to the deep cleaning for a certain area and also asked about cleaning my ultrasuede three seater couch. He quoted me around $200 and stated I would have to pay cash since the ticket was already filled out, which seemed fishy to me. I declined that service. I was relatively happy with this visit, though surprised how quick they finished (less than 30 min) and had spent an extra $40 over the Groupon, which was fine by me.
The second time, everything with the scheduling was fine, no issues there. The tech though used a different machine than the previous. He used a machine that appeared to be what you would use to clean/buff tile. There didn't seem to be any vacuuming or suction of any kind. He did spray the carpeting down first, but it was left more damp than the previous visit, and while it looked clean, any dark spots came back within a couple days. I had also asked about deep cleaning and was told a much different price over the phone than I was in person.
They just seemed shady all around and I would not use this company again.
