I can provide you with some of the best robot vacuums from 2020. However, please note that newer models might have been released since then, so it's a good idea to check for more recent reviews and rankings. Here are some of the top robot vacuums from 2020:
iRobot Roomba i7+: The i7+ impressed users with its powerful cleaning performance, self-emptying base, and smart mapping capabilities. It can navigate efficiently and automatically empty its dustbin into the base, which means less frequent emptying for you.
Roborock S6: This robot vacuum offered excellent cleaning performance, advanced mapping capabilities, and versatile functionality at a relatively more affordable price than some other high-end models.
Neato Botvac D7 Connected: Neato's D7 stood out with its laser-based navigation system, strong suction, and smart features like zone cleaning. It performed well on different floor types and allowed for customized cleaning areas.
Eufy RoboVac 11S: For a more budget-friendly option, the 11S was well-regarded for its slim design, quiet operation, and decent cleaning performance on hard floors.
Shark IQ Robot Self-Empty XL: Another self-emptying model, the Shark IQ Robot, garnered attention for its powerful suction and large dustbin capacity, making it suitable for homes with pets or high-traffic areas.
Samsung Powerbot R7070: Samsung's robot vacuum stood out for its strong cleaning performance, edge-cleaning capabilities, and compatibility with virtual assistants like Amazon Alexa and Google Assistant.
Keep in mind that technology evolves rapidly, and newer models may have been introduced with more advanced features since 2020. To get the most up-to-date information on the best robot vacuums, I recommend checking recent reviews and rankings from reputable sources before making a purchase.
