I don't specifically know about the Cabrio, but my mom has a top loader without an agitator. It is a GREAT machine. She doesn't tell it how big the load is - it senses it. She uses the high efficiency detergent. It holds a ton of clothes, and gets them clean. It's very efficient with water. It's a lot of fun to just stand there and watch it work - ha ha!
I don't know how it does the job without an agitator (yes, the thing that moves around in the middle) but it does!
Sounds like the landlord is buying a quality appliance! Congrats!
