Commercial Cleaning Equipment: Floor Machines, Extractors, and PMs

What the work looks like

Commercial cleaning is done by janitors, custodians, and building service workers in offices, schools, hospitals, warehouses, and retail stores. The daily work is mopping, vacuuming, trash removal, and restroom cleaning. The periodic work (weekly, monthly, quarterly) is floor care: scrubbing, burnishing, stripping and waxing, and carpet extraction. Floor care is what separates a $15/hr entry-level porter from a $22/hr floor tech.

The main equipment:

• Auto-scrubber (walk-behind, like the Tennant T300 or Clarke Focus II): solution tank, brush or pad deck, squeegee and recovery tank. Fill with water and floor cleaner, scrub, pick up dirty water in one pass. Used on hard floors.
• Burnisher (high-speed buffer, 1500 to 2500 rpm): polishes floor finish to a high shine. Propane, battery, or cord.
• Low-speed floor machine (175 rpm): strip, scrub, or spray-buff. The workhorse for floor finish work.
• Wet/dry vacuum (Shop-Vac, Nilfisk, Numatic): water pickup, debris pickup, filter hand-tool use.
• Carpet extractor (hot water extractor, like Bissell BG10 or Nilfisk AX14): pre-spray, injection, vacuum recovery in one pass.

Job titles: Custodian, Janitor, Building Service Worker, Floor Care Technician, Lead Custodian, Supervisor. Pay $15 to $24 per hour. Floor tech is the specialist track.

Safety and tools

Chemicals:

• Never mix bleach and ammonia (chlorine gas).
• Never mix bleach and acid cleaners (chlorine gas).
• Read the SDS (safety data sheet) for every chemical you use. It is required by OSHA HazCom (29 CFR 1910.1200) and it is on file where you work.
• Label every secondary container (if you decant a concentrate into a spray bottle, label it).

Electrical:

• Auto-scrubbers, extractors, and vacuums with cords: keep the cord out of the solution tank's path. GFCI outlets required within 20 feet of water use.
• Propane burnishers: use only in well-ventilated spaces. Carbon monoxide from a propane burnisher indoors has killed workers.

Floor hazards:

• Wet floor signs in a visible arc around any wet area. OSHA 1910.22 requires walking surfaces be kept clean and orderly.
• Squeegee the floor as you go. A wet floor is a slip hazard and a lawsuit.

Tools and PMs: every floor machine has a daily, weekly, and monthly PM (preventive maintenance). Daily: rinse recovery tanks, rinse pads, wipe the machine. Weekly: check squeegee blades for tears, rotate them. Monthly: battery water levels (if lead-acid), brush or pad wear, belt tension. A machine that gets daily rinse lasts 5 to 10 years. A machine that does not lasts 1 to 2.

Your first exercise

If you have access to any commercial cleaning equipment, read the owner's manual. Identify the solution tank, recovery tank, squeegee, and brush or pad mount on an auto-scrubber. Fill, operate, and empty it properly once, with supervision. If no access, watch a manufacturer training video (Tennant, Clarke, Minuteman, Nilfisk all have free YouTube walkthroughs).
