Commercial use-Most vacuums I see used are ----Sanitaires!One vacuum I spotted at food Lion being used on their floor mats was a chromed hood Green body dirt cup machine.It ran very quiet-looked new.A car dealer here tried a Riccar Radiance sold to them by a former dealer here----DID NOT HOLD UP-replaced with a Sanitaire.Seems like Sanitaires or their derivatives are still the most common commercial vacuums.Cheap,easy to service.Clean airs fair out LESS well under that use.And remember NO--REPEAT ---NO vacuum is going to hold up under food service use.The food grease and grunk will clog,corrode,and kill them!That is why those little Bissel sweepers are still popular in food service--brooms,too.And for hard floors-mops.
