I compiled this information while confused about what the different models of vacuums mean.

Side note that it seems like most sources of review and discussion on robot vacuums are AI slop or paid promotion, including pretty much all of youtube and reddit. Many reviews lack direct comparison of the different models, the model numbers are intentionally obscured by the brand, and the pricing changes regularly with no clear reason.

Useful sources regarding the mentioned models:

• MatterDevices has a database of vacuum robots with their model names
• User Manuals and FAQs - Dreame Official Site (archive) lists some non-US models and their model numbers.
• Vacuum Wars Dreame Robot Vacuum Buyer’s Guide 2026 (archive) has a convoluted description of the differences between the models.
