Browse the full range of robot vacuums on eBay → Prices move fast. See the biggest price drops across every category this week →Check the battery and ask how old it is. Batteries are a wear item on robot vacuums and degrade over time. Ask the seller how long the previous owner used it and whether the battery still holds a full charge. Replacement batteries are cheap on most models, so factor in 40-80 dollars if you need one. Some sellers will mention the battery was recently replaced or the unit is less than a year old.
Confirm the dock and power-on, and check the brushes. Verify it comes with the charging dock and that both power on and dock correctly. Check that the main brush and filter are present and not caked with dust or hair (these are cheap to replace). Confirm the unit has been factory-reset and unpaired from the previous owner's app and account, otherwise you will not be able to set it up with your own.
Self-emptying models carry the base value. Models like the iRobot j7+ and Roborock S8 have a self-emptying base that stores weeks of dust and is worth significant money on its own. If the listing includes the base, the total value is much higher. Confirm the base powers on and empties correctly.
Verify the app still supports the model. Mapping and no-go zones require the mobile app, so confirm the model is still app-supported by the manufacturer. Older models may have been dropped, so check before buying if the app is important to you. Most current-generation models have at least 3-5 years of app support.

Yes. Favour high-feedback sellers, check that it powers on and docks, look for detailed photos of the actual unit, confirm all parts are present, and lean on eBay's Money Back Guarantee if anything arrives damaged.
Replacement battery (if the current one is aged), replacement brushes and filter (consumables that wear out), and possibly a new main or side brush. Budget 50-120 dollars extra if the vacuum is several years old.
The base connects to the vacuum and automatically empties the robot's dustbin into the base, which stores dust for weeks before you need to empty it. This is only available on premium models like the iRobot j7+ and Roborock S8.
Check the battery still holds a charge, confirm it comes with the charging dock and powers on and docks correctly, verify the brushes and filter are present and not caked, and make sure it has been factory-reset and unpaired from the previous owner's app. Verify the model is still app-supported for mapping and no-go zones. Check the seller's feedback score (higher is better).
