What you give up at the lowest prices
The cheapest robot vacuums usually clean in a random bump-and-turn pattern instead of mapping your rooms. They still pick up daily dust and crumbs on hard floors, but take longer and can miss corners.
Expect smaller dust bins, shorter run times and weaker suction on carpet. Self-emptying bases are rare at the bottom of the price range.
Where a little more money goes furthest
Stepping up to gyroscope or lidar navigation is the biggest upgrade: the robot cleans in rows, knows where it has been and lets you block off rooms in an app.
If you have pets, a rubber roller brush tangles less than bristles and saves a lot of cleaning.
Buying cheap on eBay safely
Check that the listing says New, read the seller's feedback score and return policy, and confirm the model number so you can find replacement filters and brushes later. eBay Money Back Guarantee covers items that don't arrive or don't match the listing.

Questions
What is the cheapest robot vacuum worth buying?
Prices change daily, which is why this page links to live listings sorted by price. At the very bottom of the range, expect a basic random-pattern robot for small, mostly hard-floor spaces. For multi-room homes, budget a bit more for gyroscope or lidar navigation.
Do cheap robot vacuums work on carpet?
Most handle low-pile carpet and rugs. Thick carpet is harder for low-cost models; look for a carpet boost feature.
Are refurbished robot vacuums a good deal?
They can be, if the seller offers a warranty and returns. Check that the battery and brushes are included and that replacement parts are available for the model.
