My company recently started service at a concrete products mfg. facility. The flooring is hard (vct and tile) with a few carpeted offices. I have been told that the fire alarm has gone off due to dust raised when sweeping, etc. We have to clean these floors twice daily. Could you recommend a quality vac with a dump bag that we could use instead of a dust mop, and regular vacuum?


You have a couple of choices. Use a treated dust mop for “dustless sweeping”. The mop head will need frequent cleaning by vacuuming or shaking outside the facility, but, if treated and used correctly, will not raise dust and it is quiet and relatively fast. Have a few spare heads available to save time by changing them out. Don’t use them with a push broom motion or you will raise dust.
Use a back pack vacuum, with good filtration and, again, keep the filters and bags clean. The fine dust will load them up quickly so insist that the units are serviced before each use. There are a number of excellent choices on the market. See your Jan San supplier or go online.
