The vacuum automatically disables the brush roll when upright/stowed and re-enables it when reclined to clean, improving convenience and reducing accidental agitation while parked.
Auto pause or standby when the unit is stood upright is appreciated for quick interruptions without dripping or running unnecessarily. This feature is treated as a practical convenience during room-to-room cleaning.
Safety and standby behaviors are mentioned in a few places, including brushroll disengaging when fully upright and a switch or quiet mode to disable auto-empty. These controls help avoid unwanted operation at inconvenient times.
Some C3-compatible electric powerheads (e.g., SEB 236) are described as having an automatic standby feature that stops the brush when you lift the handle, and certain models also mention park-system shutoff behavior. This feature is attachment/model dependent, not universal.
Standby/auto brush behavior is mentioned in at least one overview, describing the brush stopping when the handle is parked upright and resuming when lowered.
Multiple reviews mention it automatically lowers power when lifted, which can save battery and reduce unwanted suction events. In quick spot cleans, that automatic behavior can feel like an extra step or delay.
Some reports describe unexpected power-offs or standby behavior, which can severely impact usability if it occurs, though other reviewers did not experience it.
