The best budget robot vacuums you can buy

We all could use a little help keeping our homes clean, and now we live in an age where robots are actually capable of lending a (mechanical) hand. Robot vacuums are some of the most recognizable smart home gadgets available today with their circular shapes and propensity for bumping into walls. While they provide an undeniable convenience, they can also have high price tags. It's not unheard of to drop close to $1,000 on a high-end robo-vac. But unlike just a few years ago, today there are plenty of budget robot vacuum options to choose from.
