  4. Check Filters: Ensure the HEPA filter and pre-motor filter are correctly seated in their compartments.

WARNING! Do not plug in the vacuum until assembly is complete. Keep fingers and loose clothing away from the brush roll during assembly and use.

First-Time Use

Before first use, ensure the vacuum is fully assembled and all packaging materials are removed.

  1. Power On: Plug the power cord into a standard 120V outlet. Press the power foot pedal to turn on the vacuum.
  2. Select Surface Mode: Use the switch on the handle to select "Hard Floor" or "Carpet" based on your cleaning surface.
  3. Adjust Height (if applicable): Some models have an automatic height adjustment. Ensure the vacuum head glides smoothly.
  4. Test UV Mode: On a non-porous, hard floor, press the UV button. A blue light indicates the UV-C lamp is active. The light will only activate when the cleaning head is flat on the surface.
  5. Detach for Above-Floor Cleaning: Press the release button to detach the pod. Connect the hose and your chosen attachment.

CAUTION! The UV-C light is harmful to eyes and skin. Never look directly at the light. Do not use the UV mode on rugs, carpets, or uneven surfaces where the head does not lie flat.

UV-C Sanitizing Mode

The UV-C light is designed to reduce microorganisms on non-porous hard floors.

  2. Usage: Press the UV button. The blue light indicates it's on. Move the vacuum slowly back and forth over the area you wish to sanitize.
  3. Exposure Time: For best results, move at a pace of approximately 1 foot per second to ensure the surface receives adequate UV exposure.
  4. Deactivation: The light turns off automatically when you lift the vacuum head, turn off the power, or press the UV button again.

WARNING! UV-C LIGHT HAZARD. Never use the UV mode on carpets, rugs, or uneven surfaces. Never look directly at the UV light or use it to sanitize skin. Keep children and pets away from the light during operation.
