Does Oreck still sell any of their uprights with the Xl21 3.5 amp motor? I noticed they refreshed a lot of their line up, but their site doesn't mention motor specs. I know for years the Platinum line used the same motor, but now all their models have the same base so it's harder the tell the difference. I watched some youtube videos with the newer models and some are soft-start now, but I still can't make out if they're the usual loud 4amps.
