Getting a new washer-dryer

We currently have the Bosch Axxis Condensation from probably 6-7 years ago. The washer cycle is over an hour and the dryer is over an hour and a half. We went to look at new washer-dyers (stackable) and found out that there are 2 kinds: one with two plugs and one with one plug. First we have to find out if we have the one plug kind (one plug into outlet in wall and washer plugs into dryer). Assuming we have the one plug (salesmen said most likely b/c we have the Bosch and they make most of the one plug models), can anyone speak to other options? We are looking for a faster wash and dry cycle. Anyone else recently purchase a washer-dyer for NYC apt??
