The Roborock S7 has a $40 extra savings coupon today. It’s not tagged with the standard Prime Day sale tags, but probably is related to that.
We’ve reviewed the Roborock S7 before, it’s marvelous. The only addendum to the reviews is you’re going to need to plan to replace that main brush sooner than anticipated, or I got a badly built one from the pre-shipping units as a review item. Still seeing what the company wants to do on that or says. 40 hours of cleaning and my brush is rekt. That’s about 4 months of cleaning. Great cleaning mind you, but dang.
I have no details on the non-Prime Day coupon / flash sale other than that it says “Coupon $40.00 extra savings coupon applied at checkout” on the S7 page.
