Benefits of Choosing the Right Size Equipment

Having the right tool for the job can make all the difference.  If you have equipment too small for a large area, your operation is wasting labor hours that could be spent making facility improvements elsewhere.  A piece of equipment too large for a job can have adverse consequences as well like poor maneuverability or the need to clear out an entire room or workspace to use it.  There are a few things that need to be determined first in order to make the correct choice to suit your needs.

Size of the Area

One of the most important things to consider when purchasing equipment is that it matches the area you’re cleaning. We recommend first measuring the size of the area you’ll be cleaning and determining the total square footage. This can be done with a laser tape measure, measurements off of a blueprint, or (for hard surfaces) by counting and multiplying tiles on a VCT floor.

Density of the Space

You will also need to consider the density of the space.  Is it a wide open space like a ballroom or corridor or are you cleaning offices that have obstacles like desks, chairs and tables? Understanding how much space there is to maneuver equipment will help you select the right pieces.

Potential Equipment Production Rates

Once you determine the size and density of the areas you’ll be cleaning, the next thing to do is to figure out how long it will take to clean it with the equipment you’re considering. To do this you’ll need to know how many square feet per hour the equipment options clean. There are several ways to determine this:

  1. Use manufacturer’s practical (not theoretical) production rates
  2. Use the ISSA 612 cleaning times to provide a third party production rate
  3. Calculate the production rate of the cleaning process by timing it yourself

Time Savings Calculation

Divide the area you are cleaning by the production rate of the equipment to determine how many hours it will take to clean the area with the specific piece of equipment.  Multiply that number by the weekly frequency of cleaning and by the number of weeks you plan to clean the area per year.  This will give you an understanding of the hours you will need to invest per year to clean that area with the tool selected.


Small changes to your process can yield big labor savings over time.  Even saving 30 minutes a day, five days a week, 52 weeks a year adds up to 130 hours of labor saved.  Think about how much more your team could accomplish with that much reserve time for other tasks.
