Coin Vacuum Motors

Motors are the heart of your coin vac, providing the significant suction power that customers expect for effective cleaning. If you’re experiencing suction loss or your vacuum isn’t turning on at all, the motors are one of the first spots you should look when troubleshooting. By replacing motors, you’ll save a significant amount of money versus buying new vacuum units. You’ll probably be surprised at the relatively low cost and installation time needed to get your coin vacuums back to full performance.

When shopping replacement motors, a good starting point is to first determine how many motors are used in your unit, as well as the diameter of each one so your new ones will fit properly. Then, figure out the wattage, voltage, and horsepower of them. Other relevant specifications include water lift (sealed suction), airflow rating (cfm), and revolutions per minute (RPM). If your current motors are the original ones, you can defer to the specs listed on the sticker/plate when finding replacements. If you have your vac manual or data sheet, always consult those documents to be completely sure you’re getting the correct new motors.

Not only will weak suction result in customers ending their cleaning session quicker and reducing their spend, there’s a good chance you’ll see poor reviews and customer complaints about poor performance.

4 Categories In List


Important Vac Motor Specifications

  • Motor Power: Expressed in Watts, kW, or HP, and it depends on the type and number of motors in the vacuum.
  • Voltage: This is a measure of electrical energy, denoted in Volts. Most car wash vacuum motors operate at 120 volts and 240 volts. There are some motors with uncommon voltage specifications that are vacuum-specific.
  • Motor Amps: The motor amps specification represents the total electrical current drawn by the vacuum, including the motor and other electrical components.
  • Water Lift (Sealed Suction): This metric measures the vacuum motor's strength and is derived from determining how many inches a vacuum motor will vertically lift a 1'' column of water. This test simulates the process of lifting dirt and debris from carpets.
  • Airflow Rating (CFM): Airflow rating, expressed in cubic feet per minute (CFM), is the rate at which air flows through the vacuum. The faster the airflow, the more effective the vacuum is at picking up dirt and debris.
  • RPM (Revolutions Per Minute): This specification tells you the maximum number of times the rotor can spin per minute. Speed plays a significant role in a vacuum cleaner's cleaning efficiency, particularly on carpets and other surfaces that require agitation. The speed of the motor varies drastically depending on the vacuum.
  • Diameter/Footprint: This is a measurement of a motor’s footprint using its diameter. Choose a motor with the same diameter as the original to prevent air from leaking. When air leaks vacuum suction will decrease impacting the customer experience.
