The BISSELL PowerForce Helix has mediocre build quality. It’s made of hard plastic, but it feels flimsy in a few places like its two wheels or brushroll plate. The dirt compartment also seems fragile and could break if dropped. You need to also attach the handle to the vacuum’s body with two screws before you can use it, which isn’t very convenient.
Unfortunately, the brushroll doesn’t stop spinning when the vacuum is on, so if you want to have it in the upright position and the head isn’t high enough, it may damage your floor. Luckily, there’s a head adjustment dial on the vacuum head.
