New unit not picking up debris

Hello,
Brand new User here…
This is the 3rd time I’ve run my machine (it’s brand new) doesn’t seem to do a very good job on hard floors. Leaves a ton of debris and pet hair. I literally have to follow it around with a broom and dust pan as it seems to just track it around from room to room.
My floors are not super dirty before use. I sweep most spaces daily. Are there recommendations? It was an awful experience unit to not work well from the start.
