Charging

Before first use, fully charge the vacuum's lithium-ion battery. Plug the charger into a standard wall outlet and connect the charging cable to the port located on the top of the vacuum's handle.

Operating Instructions

Power Settings

The vacuum features an intuitive IQ display that provides real-time readouts on battery life and performance. There are two primary power settings: one optimized for bare floors and another for carpets. Use the control buttons on the handle to switch between modes and adjust suction intensity as needed.

Maneuverability and Reach

The lightweight design and swivel action of the vacuum head allow for easy navigation around furniture and into tight spaces. For hard-to-reach areas, the vacuum can be converted into a removable hand vac, or additional attachments can be connected to the wand for extended reach.
