The R7040 has a good build quality. It’s made out of hard plastic, with a glossy finish on top and matte finish underneath, and the entire vacuum feels sturdy. Its design doesn’t look as premium as some other robot vacuums, like the Roborock S4.
The display controls are well-positioned on top, and the dust bin is made out of see-through plastic, so you can see how full it is. Unfortunately, the emergency switch is at the bottom, which could be hard to get to. However, no assembly is required on the vacuum itself as only the dock station needs to be set up.
