This stellar robot vacuum and mop hybrid has a coupon for (wait for it) $180 off

Save $180: The Roborock S6 robot vacuum and mop has a $180 coupon on top of its $50 discount at Amazon as of March 25.

The Roborock family has welcomed a new member. The brand, known for its robotic vacuum-mop hybrids with suction that rivals that of Roombas, released the S7 earlier in March. Two words: Sonic. Mopping.

The S7 was set to go live on Amazon and Walmart on March 24. The listings technically exist at both places now, but are saddled with "out of stock" and "currently unavailable" warnings with no restock date (or ability to add to cart) in sight.

Thus, the S6, one of our absolute favorite robot vacuums at the moment, is already back in the spotlight — and rocking a $180 coupon at Amazon, bringing the beast down to $419.99. This is on top of a $50 discount that's already applied, though the S6 hasn't been listed higher than $599.99 since last summer.  Read more...
