This Dyson vacuum is in excellent mechanical condition and runs as good as the day it was manufactured. Even though this vacuum ran perfect and did not need it, before we sell any Dyson Vacuum, we have our service department completely go through it and give it a 30-point inspection and service, replace any worn parts, and professionally clean it and wash the bag. Dyson Vacuums are great because they are bagless, dont loose power and powerful cleaners.
