Parts Meaning
BoostIQ Feature
When the BoostIQ feature is enabled, RoboVac will automatically increase the suction power if it detects stronger power is needed to ensure the best clean. BoostIQ is ideal for cleaning thicker carpets and hard-to-sweep messes, which will reduce the total cleaning time, but increase the noise level. If the vacuuming noise caused by BoostIQ disturbs you, you can disable this feature. This feature only works in Auto and Single Room cleaning modes. In Auto or Single Room cleaning mode, press on the remote control repeatedly to adjust the suction power level.
• The corresponding icon is displayed on the remote control.
