Cleaner

This is arguably easier than vacuum’s S21. Everything before the bracket drill is straight forward, making your only focus the end. The bracket drill in Cleaner is way easier to hit because the drill sets you up in a more comfortable position. If you’re struggling on vacuum then try this.

A case where the difficulty was raised by a single, soul-infused drill after easier bracket drills appeared than in Vacuum S21. Still, perhaps because it was a 22 in its prime, it has more technical difficulty than most 21s. Especially the same-note hit that comes after the stairs in the middle is surprisingly tricky, so if you get tripped up there, it becomes a major obstacle to breaking on. Perceived difficulty is around mid-high.

It's just raw stamina with no particularly difficult patterns.

There's nothing particularly difficult. Just be careful at the end.
