Daily driver is a Factory Rebuilt Kirby Classic Omega, with a 4 row brush roll, and Heritage 2 bag system, with a G series bag adapter, using the G5/6 Hepa Bags. Then for all above floor cleaning, an Electrolux Silverado with a 1692 Headlight PN,,love the Sidekick too. Ocasionally use a Filter Queen Tripple Crown,,and have Central Vac in the house, but dont like to wrestle with that long hose. Mostly use the Central Vac for cleaning out the car, and garage.
I clean a large fitness center once a week for a friend that owns a cleaning service, and usually take the TriStar to do that.
She has a Panisonic/Hoover DAM style commercial upright that i dont like, as there is only suction on the one side of the brush roll,(and the suction is poor anyway),and the hose going up the back end to the bag is prone to clogging.
She also has a back pack vac that i can use, but not crazy about it either because after about an hour with that thing strapped to my back, im ready to take it off. Takes about 2 hours of vacuuming to get the job done there, so ive found the TriStar does the best job, going around the fitness equipment, ect, and is the easiest to use in that situation.
May have to take the Classic Omega over to the fitness center sometime and see how it does.
