Question

Post construction cleaning of 100,000+ sf residence hall. All concrete floors. Required to sweep, mop, clean, and high speed buff floors. Any recommendations on equipment? We were going to utilize just brooms, vacuums, and 2 walk-behind floor buffers....some long hallway expanses, but many smaller bedrooms. Would use of larger auto sweeper and auto scrubber save time or be suitable for this service?


Answer

Generally, the larger the machine, the greater the coverage and the faster the work is done. Less time translates to reduced labor cost.
The only concern is the size of the spaces you must service. Too large a machine will be difficult to use in tight areas and prove to be no time saver at all. If you fit the machine to the space you will definitely save time.

If the floor is polished concrete, possibly a high speed buffing may be worthwhile, but usually that operation is reserved for a buffable finish, to restore its appearance. Try this in a small, clean section to see if it makes any improvement. I suspect the concrete is too hard to be affected.
