Robot vacuums are an excellent way to keep your home floors neat and tidy, but some of the best models on the market can cost upwards of $500. Fortunately, though, you don’t need to spend nearly that much dough to score an awesome robot vac. In fact, some of our favorite self-efficient bot sweepers can be had for $250 or less. For our intents and purposes, we’ll call these models “cheap robot vacuums,” with cheap referring exclusively to price and not overall performance.
