The iRobot Roomba E5 has a great build quality. It’s made out of hard plastic, which is glossy on top and a bit on the bumper, and the rest has a matte finish. The vacuum feels sturdy, and while the dirt compartment feels like it could crack if dropped, it’s more solid than the dirt compartment on other vacuums because it’s partially made out of hard matte plastic. There are three buttons on the top to start a cleaning session, do a spot clean, or return to the dock. There are also light indicators for the battery, Wi-Fi connection, and the status of the vacuum all above the controls. The brushrolls are also rubber, which isn’t something we see on vacuums very often, and they help reduce the amount of hair that gets tangled. Like most robot vacuums, you don’t need to assemble this before using it.
