I asked my colleagues and share some ideas with you. This RoboVac can be used on low-pile carpet, tile, laminate, and hardwood floors, but is not suitable for high-pile carpet like shag carpet.
The RoboVac works with most carpets that are thinner than 12mm with fiber length shorter than 10mm. Please feel free to contact us via email@example.com to clearly describe your problems, we are glad to help you soon. Thanks!
