#1 How strong is the suction?
As mentioned above, this vacuum has two different cleaning modes, low gear and high gear. When we tested this vacuum, it performed pretty well, but overall suction did feel a little lacking, even on high gear.
Most vacuums have a “pull” on the carpet as it agitates fibers and pulls debris up. We didn’t really feel that same power with the Onson.
That being said, it did have a pretty good performance during our tests, but we can’t necessarily say that the performance would continue when faced with ground-in dirt or debris.
