Verdict

The Roborock S7 Max Ultra is a high-end, 2-in-1 hybrid robot vacuum and mop that delivers 5,500 Pa of HyperForce suction power paired with a durable, all-rubber brush roll to minimise hair tangles. It features the advanced RockDock Ultra base station, which automates maintenance by self-emptying the 350 ml onboard dustbin into a 2.5L bag, self-refilling the robot's water tank, and washing and hot-air drying the mopping pad to prevent odours. Key advantages include a 180-minute runtime, LiDAR-based quick mapping, Reactive Tech obstacle avoidance, and a VibraRise mopping system that scrubs floors 3,000 times per minute while automatically lifting 5mm on carpets to prevent cross-contamination. However, notable drawbacks include its bulky docking station design, a high premium price tag, slightly suboptimal deep-cleaning performance on thick carpets, and occasional difficulties detecting thin cables.
