How much water does my Rainbow water bowl need?

Too much water, it'll make a mess. Not enough water, it won't do its job correctly. In this video we will show the water fill indicators and how much water your Rainbow water bowls needs.



Important Safety Tips

  • Always make sure your machine is unplugged and the power button is turned off, before servicing your vacuum.
  • Always make sure your hands are dry and free from moisture before servicing your machine.
  • Be sure to wear gloves when servicing your machine to prevent any cuts or scrapes.
  • If you are uncomfortable working on your vacuum, please don’t hesitate to contact us at and we can help you through the process or you can send it into us to fix it for you. 




On the right we show an E series 2 quart water bowl and on the left is an SE 2 quart water bowl.

The water fill indicator for the E series is the bump in the middle.

The SE series indicator is the tall peg in the middle.

You will want to pour water in just until the top of the indicator is barely covered. Now it's ready to be reinstalled on your Rainbow vacuum!
