Anker's Eufy robot vacuums are up to 41 percent off at Amazon

Anker's Eufy brand offers some very affordable robot vacuums that just got even cheaper thanks to a sale on at Amazon. The most interesting model is the Eufy BoostIQ RoboVac 11S Max that's available for just $160, for a savings of $90 (36 percent) off the regular price. That's very inexpensive for a model that earned a spot in our budget robot vacuum guide thanks to its attractive looks and super solid design. The RoboVac 11S Max is missing certain features like WiFi connectivity, which isn't surprising given the price. However, it's still easy to control using the physical remote that allows you to set things like cleaning schedules or change the suction power using BoostIQ or Max modes. It cleans both hard and carpeted floors with up to 2,000 Pa of suction power, and is pretty decent at avoiding collisions considering the price.
