Max suction

All of a sudden my L40 ultra doesn’t sound like it is on max suction even though it is programmed to be. Is there something that could be stopping it from being on max suction?
I also had it programmed to mop and vac but it only seemed to be mopping. Any ideas what could be causing this?

Dear [RU275730],
