The SC380 is a powerful and sturdy machine that is a great fit for most homes and businesses. This Electrolux central vacuum unit may seem bland compared to the PU3900 or Electrolux PU3650 Central Vacuum, but that doesn't mean that it's a pushover. With 650 air watts, this is a very powerful and efficient central vacuum that can cover 5,000 square footage. It's perfect for a wide variety of settings. Additionally, it's also a sturdy, durable unit that will stand the test of time. This is also a very user-friendly unit, with its easy-to-empty dust receptacle and astonishing 10 year warranty. The SC380B also has a very low operating volume because of innovative motor chamber insulation and muffler exhaust.
