<human>: Can you give me the gist of the text in a nutshell?

My boyfriend (21M) and I have been living in a new apartment complex for about 6 months. We also live in an area where there are also a lot of IT jobs who outsource workers from India. So most of the tenants in my complex are Indian. My boyfriend who had an Indian nanny his whole life had mentioned their schedules are usually opposite of ours in the US. Like they will stay up much later to get their house work done or spend time with their families. I didn't think it would be a problem, cause the race of my neighbors isn't something I think or care about. 

Now my neighbors don't speak any English and are EXTREMELY loud. They will vacuum multiple times in the middle of the night. As in turn there vacuum on for 10 minutes, then turn it off, then turn it back on again. This has happened every night since we have moved in. If they aren't vacuuming they are making these noises that I can't even describe. It sounds like they are picking up their furniture a few feet and then dropping it. Our whole apartment shakes. Its gotten to the point where I will be crying in bed at 1am because all I want to do is sleep but they won't shut up. 

My boyfriend has tried to talk to them several times but since they don't speak any English its hard to tell them they are being loud without sounding rude. Each time they just smile and wave at my boyfriend when he knocks on their door. I've considered calling the complex and complaining but the only problem is my boyfriend has his medical card (in our lease there is no smoking even with a medical card) and I'm worried that if we complain about them being loud, they will complain about us smoking. I'm not for certain if they know we smoke because we take every precaution to make our apartment NOT smell when we smoke. 

This is our first apartment together so we have never had to deal with issues like this before. Is there something that I can do without making my neighbors angry?
<bot>: My (21F) neighbors (30ishMF) don't know how to be quiet at 1am and its driving me crazy.
