Ive owned a Hair Styling business for 30 years, and have ALWAYS had a KIRBY Classic Omega in the shop.
The Omega has had HARD use,,,being used MANY times during the work day. My shop is in operation 5 days a week.
The Kirby has NEVER EVER failed, EVER, and is STILL going strong to this very day.
Of course im careful about changing the belt whenever it starts to weaken, and put a new brush roll on the Omega about every 5 yrs or so,,,whenever the brushes get worn down enough to where adjusting wont work anymore.
Several yrs ago I did put a Heritage 2 Mini Emptor on the Omega, with a G Series bag adapter to take the G series Hepa bags.
Vacuuming up ground in human hair out of carpet pile is not easy, so it does require a machine that gets down to business. The Kirby handles it easily, and has for 30 years now.
