ANY vacuum can clog when used for foodservice cleanup.Better to use a carpet sweeper or a broom.Some of the clean air machines brought into the vac shop were a MESS--took longer to clean out than the direct ones.And there was a Sanitaire that a place had -it ate a mouse.Half was in the bag other caught in the brushroll.A Carpet Pro even was used to pick up a WHOLE hamburger-bun and all.That vacuum had a paper sign on it saying it was not a "magic" vacuum cleaner.Sure wasn't.Thought you picked up whole burgers with your hand-NOT a vacuum cleaner of any sort.Was helping Bill the vacuum shop operator on these-was GROSS!!!He did sell a lot of Bissel puch trype sweepers to eating places.-Brooms,too.
