iRobot Corp. released two new robots into the world on Tuesday: a Looj 330 gutter-cleaning robot and a Roomba 600 series vacuum cleaning robot.

The new Looj is an improvement on previous models, the company said, because it has a faster, more powerful auger, a lower profile, and smarter operational features. The new entry-level Roomba 600 Series robots incorporate optimized airflow and an improved brush design for more thorough and effective cleaning. Roomba 600 Series will replace the Roomba 500 Series in iRobot’s dry floor care line-up in most regions worldwide.

The iRobot Looj 330 gutter cleaning robot is available in North America for $299. The Roomba 600 Series pricing starts at $329.99.

iRobot is based in Bedford.
