Your eufy RoboVac should be able to pick up most of the debris it runs over, as long as the debris is not too large or heavy. Here are some tips to help fix the issue if your RoboVac isn’t picking up debris properly:

• Make sure that the filters, dust collector, rolling brush, and side brush(es) are inserted or attached to the vacuum properly. Refer to the video: How to Clean Dust Collector, Filter, Rolling Brush and Side Brush of your RoboVac?
• Ensure the vacuum is set to the proper suction settings; 

when on tile, linoleum or hardwood floors, generally, a lower suction setting is needed. 

On carpeting, a higher suction setting will be necessary. 

If the area being cleaned is a mix of both, the BoostIQ option may work best. 

• Don’t leave objects the vacuum cannot pick up on the ground in the area it’s supposed to clean, such as bottle caps, coins, wires, pet droppings, wet objects, sharp objects, or burning objects. Generally, if the debris is too large to get past the rolling brush, it will not be able to be picked up by the vacuum cleaner. 
• Perform routine maintenance, and if necessary, replace any wear and tear parts. Follow this link for more information on how to perform proper maintenance on your RoboVac accessories.
• If the RoboVac is not picking up anything, check the rolling brush to ensure it is spinning. If not, check the circular end of the rolling brush to see if it spins at all. If it does not, you may need to replace the brush. If replacing the brush does not fix the issue, contact customer support.
• If the RoboVac is not picking up anything, the suction motor may not be sucking up debris. Remove the dust collector and check the suction inlet behind the dust collector to see if there is any trapped debris causing the issue. Make sure that the suction outlet on the vacuum (usually covered by a small plastic grate) is also cleared of debris. If the suction motor is not working after trying this, contact customer support. 
• On iPath Laser Navigation series RoboVacs, please be aware that the vacuum will not clean in No-Go Zones when they are set on the map.
