## Long description

Electrolux ER81UW3SW is a bagless robot vacuum designed for autonomous floor cleaning in homes and apartments. Equipped with LiDAR navigation, it scans and maps rooms to plan efficient cleaning routes. The unit offers up to 208 minutes of runtime on a single charge and returns automatically to its base station for recharging; a full charge takes approximately 6 hours. With a cleaning diameter of 35.2 cm and a net weight of 12.8 kg (base station weight 4.14 kg noted separately), this model balances cleaning coverage with compact operation for everyday scheduled cleaning tasks.
Advantages
The bagless design eliminates the need for disposable dust bags and simplifies emptying and maintenance. LiDAR navigation provides accurate mapping and systematic cleaning patterns, reducing missed areas and repeated passes. Extended runtime up to 208 minutes supports longer cleaning cycles across multiple rooms, while automatic return to the base station ensures the robot docks for charging without user intervention. The 35.2 cm cleaning diameter covers a wide path per pass, improving efficiency on open floors.
Suitable for
Scheduled daily or weekly cleaning of apartments and houses
Cleaning medium to large rooms with mixed floor types
Homes where hands-off navigation and mapping are preferred
Households seeking a bagless solution to simplify maintenance

How to use
Place the base station on a level surface with clear space around it and allow the robot to complete its initial mapping run so the LiDAR system can scan the environment. Schedule cleaning cycles via the robot controls or the compatible app if available, and set no-go zones or room priorities during mapping if the feature is supported. After each cycle, empty the dust bin and check filters according to the maintenance intervals indicated in the user manual. If the robot docks to recharge, allow it to complete a full charge of about 6 hours for optimal battery performance.
Usage recommendations
For best results, remove loose cables and small objects from floors before cleaning, keep thresholds and floor transitions clear during initial mapping, and perform regular bin and filter maintenance. Use scheduled cleaning for consistent results across multiple rooms and allow the LiDAR mapping to update after significant furniture changes.
