I would give it a zero if they had one. After one month we dropped the wand on the ceramic tile and the plastic on it broke in 2 exposing the wires. I called customer service and they said of course plastic will break if you drop it on a hard surface. I guess they should mark their vacuums FRAGILE and certainly not durable. Maneuverability I guess you can move it if you don't accidentally drop it. Ease of Maintenance Get the duct tape and super glue because the parts are back ordered. Suction Performance Who knows it only worked 3 times before breaking. Versatility It is versatile. It starts as a vacuum and ends up trash. Design Try using a softer plastic next time like Hoover. Something less brittle. Durability Yeah right. See above. They did not stand behind a 30 day old vacuum after it broke.
