Meaning what, exactly? You call a phone number, and a guy shows up at your door with a washer, installs the pipes and bits for you, and then comes back in 4 hours to pick it up. For 5,000 pesos (about $2.50)! How cool is that? We don't have to deal with machine maintenance, and there's no machine taking up precious space in our reasonably-sized but small apartment. I'd say something like "I can't believe they don't have this in other places", but honestly it's hard for me to imagine how it's worth it for the company. It must be, though, or they wouldn't do it...and I for one am not complaining.
