You can save big today on a new Roomba. The flagship Roomba Max 705 + AutoEmpty dock, which launched in April, is available for $320 off. The robovac, which typically costs $899, is on sale for $579. Enter our exclusive code ENG320 at checkout to snag the deal. iRobot says the Roomba Max 705 offers 180 times the suction power of its budget Roomba 600. The high-end model has dual multi-surface rubber brushes with an anti-tangle design. That could be especially handy for pet owners. The robovac includes an edge-sweeping brush to handle corners and edges. There's also a feature called Carpet Boost that automatically increases suction when it reaches carpet. And it uses LiDAR for precision navigation and obstacle avoidance.

This model doesn't mop, which may be harder for some to justify at its typical $899. But for $579, a high-powered vacuum with an auto-emptying dock starts to look more sensible. Just remember that code: ENG320. Roomba Plus 405 Combo (iRobot) If you're looking for something more affordable (but with a different feature set), there's the Roomba Plus 405 Combo. Although its suction isn't as powerful as the aforementioned 705 model, this one does mop. Its AutoWash dock supports up to 45 days of auto-emptying and four weeks of mopping and pad washing before requiring your attention. The iRobot Roomba Plus 405 Combo robot + AutoWash dock typically retails for $799. With our code ENG320, you can have it for $479.
