Narwal offers some of our favorite robot vacuum and mop combos. They are powerful, great-looking, and offer some fantastic features, competing only against the best in the industry. They are not cheap, though. This is why we get excited when we see good deals like this one. The Narwal Freo is currently at a massive 50% discount, which equates to $700 off the original price. This brings the price down to $700.
