It will pick up crumbs, but pet hair gets spit back out in a different place from where you picked it up. Called Shark - twice - and got nowhere ("empty the dust cup" - it wasn't anywhere near full). Also, it only runs for 12 minutes on a charge and you can't leave it plugged in, but have to charge it 7 hours once it dies. None of this was clear in the description. Wayfair will take it back 
for 25% of the selling price. I won't be ordering from them again.
