From pet hair to dust, keeping your home clean is easy with the best robot vacuum cleaner. However, robot vacuums can be pricey if you don't know where to buy one.

Fortunately, Amazon is making its robotic assistants more affordable than ever. For a limited time, the iRobot Roomba 675 is on sale for $199. That's $100 off and one of the cheapest Roombas we've ever seen.

Like most Roombas, the Roomba 675 uses a three-stage cleaning system to loosen, lift, and suck dirt from a variety of surfaces. It can be used on hardwood floors, carpets, tiles, and everything in between.

The vacuum cleaner also has a dirt detection sensor that alerts the robot to focus on high-traffic areas of the house. Meanwhile, a cliff detection sensor prevents it from tumbling down stairs or other drop-offs in the house.

Cleaning can be scheduled through the iRobot Home app, and the vacuum cleaner can be controlled using voice commands from Alexa or Google Assistant. As for battery life, the Roomba 675 will last up to 90 minutes before automatically docking.

iRobot currently sells the Roomba 675 for $229, while Amazon's price is an additional $30 below iRobot's selling price.
