One problem with the SS is when full. If you lift the SS to move/dump, the debris that's picked up falls out all over.
This was illustrated beautifully by one of the panelists on the View: Joy, a sweetheart with a lovely sense of humor. She picked up cheerios with the SS and then lifted the SS off the floor. Cheerios fell out all over her clean floor.
I have one, but never used it much. I uses 4 AA rechargeable batteries, it is no powerhouse. It has no wheels so it’s omni directional. It comes with a sewing seam (thread) ripper, you will need this to remove much dog hair that gets wrapped into the brushes.I should mention, I have not used other sweepers.DIB
