VEVOR Kitchen Utility Cart, 3 Tiers, Wire Rolling Cart with 450LBS Capacity, Steel Service Cart on Wheels, Metal Storage Trolley with 80mm Basket Curved Handle PP Liner 6 Hooks, for Indoor and Outdoor

This cart is awesome. Rolls like a dream

I wouldn’t try it myself.

It is sturdy enough to hold and move a countertop dishwasher. Check the size to make sure it fits. Very durable high-quality cart. Love mine!

Yes it is very sturdy and rolls smoothly and easily.

As long as it weighs less than 666 pounds. You good.

The cart is sturdy but I've never seen a countertop dishwasher so I can't really say. I have a microwave on top tier and an air fryer stored on bottom tier. My center tray holds oven mitts, paper plates.

Yes

I don't think it is big enough to fit a dishwasher on it. It is sturdy enough but check the actual inches of what you intend to put on it before ordering.
