Roborock S8 MaxV Ultra vs Roborock Qrevo Edge 2
Quick take: The Roborock S8 MaxV Ultra costs $300 less; the Roborock Qrevo Edge 2 has stronger suction (25,000 vs 10,000 Pa); the Roborock Qrevo Edge 2 runs longer per charge (188 vs 180 min).
Which one to buy
Three hundred dollars and a generation separate these Roborocks, and the newer one isn't better at everything. The Qrevo Edge 2, at $1,100, wins on cleaning. In independent testing it pulled 94% of embedded sand from carpet against a 78% average, mopped at roughly double the category average, and picked up 89.5% of pet hair. It's also rated at 25000 Pa against the S8 MaxV Ultra's 10000 Pa, and sits lower at 3.14 in against 3.8 in.
Where it slipped is avoidance. The Edge 2 dodged 14 of 24 test obstacles, behind its own predecessor and the category average, and its owners name poor avoidance as a recurring complaint. S8 MaxV Ultra owners say the opposite about theirs: shoes, cables, socks and dog toys get avoided consistently, to the point that pet owners leave it running unsupervised. The S8 also holds 400 ml in its bin against the Edge 2's 240 ml.
Each has its owner gripes. On the Edge 2, at least two owners got a first unit that wouldn't charge or dock, and others report inconsistent mop pressure and odd cleaning patterns. Roborock's fast run of Edge models also leaves owners unsure which features each one has. S8 MaxV Ultra owners complain about a massive dock, refilling the tank every 3-4 cleans, a strip missed along baseboards, and mopping that still won't tackle dried or sticky messes.
In a reasonably tidy home, the Edge 2 is the better cleaner and worth the extra $300, especially over carpet. The S8 MaxV Ultra kept its place where the floor is a minefield of cords and toys, since a robot that avoids them reliably is worth more there than a better carpet score, but it is now discontinued; Roborock's successor is the Saros 20 Flow at $1,500.
Roborock S8 MaxV Ultra
For a home where cords, socks and pet toys are always on the floor, its obstacle avoidance and bigger 400 ml bin matter more than the Edge 2's cleaning scores; now discontinued, with the Saros 20 Flow as its successor.
Roborock Qrevo Edge 2
Worth the extra $300 for a tidy home with carpet and pets, where its 94% embedded-sand result and strong mopping pay off, as long as you test it hard on arrival.
