Hi Floris,
We’re sorry that you’re encountering this issue. Our R&D team has informed us of two ways to troubleshoot this issue:
1. Try to loosen the back wheels of the Seagull Pro, as this has the opportunity to correct the pathing of the machine and resolve the issue.
2. Ensure that your collection tray isn’t complete when this issue occurs, as this can affect the Seagull Pro’s suction.
If you’re still having issues with your product after trying these resolutions please consider reaching out to our VIP customer service team at service@aipervip.com
