Just within the last few months I've been cleaning a fairly large dealership. They are currently remodeling the place to add a larger waiting room and sales area. I'm having trouble coming up with decent options for this type of layout. I have used mostly an Oreck Commercial U2000R-1 which the guy before me badly neglected. The problem I have with the Oreck is I don't believe it does well on any floor surface in the place. on the tile floor, to the hardwood floors, the area rugs. The brush roller and performance is subpar. I did however try and use a Miele quickstep with the SEB 236 and that does well but not practical. I also have started using a Riccar R10S which the brush roller on that is nice and does well on the area rugs and decent on the floors. I was thinking about a backpack vacuum? What I'm struggling with is the lack of a decent powerhead or easy of use in switching from powerhead to tools. My thought was strap a Miele C3 to my back but I'm just now sure how that would hold up, and the smallish bags? So I opening this question to the community. Are there any options I haven't considered and I want to hear a lot of input. Any thought would be appreciated.
