Bag-full indicator

A bag full indicator next to the upper compartment changes color as the 4.5 liter bag fills, alerting you when it is nearing capacity so you can replace it before suction drops or dust backs up in the airflow path, and this review shows how easy it is for owners to see at a glance when the bag is due for a change.

A simple pressure based bag full indicator reliably alerts you when the bag is nearing capacity, and years of use show it continues to work without fuss so you can replace the bag before suction drops.

The dock can signal when the disposal bag needs attention via a front LED indicator in some descriptions, helping prevent overfilling.

Bag-full indication is supported via dock LEDs and/or on-screen/app alerts, helping users know when to swap the sealed dust bag before performance drops.

Bag-full indicator is a commonly cited convenience feature (light/scale) that helps users know when to replace the bag and maintain performance; one reviewer notes it can trigger during certain conditions but is still useful overall.

Some reviews mention getting notifications when the dirt bag is full or an indicator/alert prompting replacement, supporting hands-off ownership. Bag capacity is typically framed in multi-week to ~60-day terms depending on usage.

A bag full indicator on the canister alerts you when the bag is nearing capacity so you can replace it before suction drops or dust backs up in the airflow path, though it does not warn you if the vacuum is accidentally used without any bag installed.

Notification support is limited in some reports: reviewers mention a lack of clear alerts for a full onboard bin, and low-water alerts for mopping can also be missing. Visual inspection of the bagless canister is often used instead.
