Looking for a third party head replacement for my Gen5 Detect.

Hey all, I'm looking for a replacement for my Dyson Gen5 detect outsize's head as the axle continues to break.

I'm on my second head under warranty and I had to fight tooth and nail to get it replaced the first time, I'm trying to get another replacement under warranty but of course support is the literal worst I have ever dealt with and they continue to literally lie and blow me off when I try to contact them about getting it replaced. They do not (and have not in more than a year) have any replacement heads or most other parts.

SO I am trying to get something out of my nearly $1000 purchase and I need to get a third party replacement head for this thing to work as it should.

My question is, which heads are compatible with the gen5 detect outsize model? I can't seem to find a definitive answer or compatibility chart for some reason. It's crazy that a huge company like Dyson has so many models and no compatibility chart because some heads are backwards compatible but some aren't? I'd just like to see which are compatible with my model, if any.

Needless to say, when this thing finally bites the dust I'm never buying another Dyson, but until then I'm going to get my money's worth.
