So I'm looking to purchase a vacuum for my company. Budget is around $500 max. The building is mostly carpet with some tile. The carpet is either this indoor/outdoor crap in the hallways, otherwise a more residential Berber-like material. The tile is typically not vacuumed but is on occasion. I believe it's porcelain. There is also an entryway... in not quite sure what the flooring is, it might be lanoleum, but like the tile it's typically mopped. I don't really know anything about vacuums, including if I should get a commercial or residential vacuum (or what the difference is). It doesn't need to be fancy, but a wand would be helpful. Something built to last is favorable. I suppose buying two cheaper vacuums is also an option. I asked our cleaning crew their thoughts. They didn't really seem to have much of an opinion. Maybe someone here can make some suggestions.
