The under-$500 category changes quickly and may be empty when established brands do not have a model or open-box unit below the line. That is useful information: a very low price often means floor-only coverage, a small filter, manual starts, a short warranty or a marketplace brand with limited parts support. This page uses live prices and shows only robots that actually qualify, followed by the closest proven alternatives when none do.

First confirm that the machine is a true robot with its own pump and filter, not a battery vacuum that must be pushed by hand. Then verify maximum pool length, replacement-filter availability and who performs warranty service. Those costs matter more than app icons on an unknown model.
If no established robot is available below $500, compare the next price band with open-box inventory. Spending a little more can add an authorized-dealer warranty, parts support and a filter large enough to finish a cycle.
Wall and waterline coverage are uncommon at this budget.
Filters, tracks, brushes and a power supply must still be available after the first season.
A long number is not useful without a reachable service network.
A known model with stated condition can be a safer value than an unsupported new brand.
Sometimes, especially through limited open-box inventory, but the established new models we carry may sit above this price. The live grid shows what genuinely qualifies today.
Usually wall and waterline cleaning, a weekly timer, fine filtration, a swivel cable and longer warranty coverage.
Only after confirming replacement filters, battery or power-supply availability and who handles warranty repairs. A low purchase price becomes expensive if a wear part cannot be replaced.
