Machine and its parts were super easy to assemble. I have carpet and hard wood flooring-switching the brush height was no problem and worked accordingly. The suction is strong and it moves around easily. I have super sensitive hearing-most vacuums have a high pitched twine that requires me to use ear plugs, but not this one, which is nice on my sensory system. Overall happy with purchase. Will write another review in the future to provide feedback on durability and function.
