Roborock S8 Max Ultra vs Roborock Qrevo Edge S5A

Both are Roborock robots with self-emptying, self-washing docks, but they sit at different levels. The S8 Max Ultra is the stronger cleaner and the more hands-off system: 8,000Pa suction, a dock that refills and drains itself, hot-water mop washing and hot-air drying, and a detergent dispenser. The Qrevo Edge S5A is lighter and simpler, with a multifunctional dock and Siri support, but its lower owner rating suggests more mixed experiences. Buy the S8 Max Ultra if floors are mostly hard and you want the least touching; buy the Qrevo Edge S5A if you want a lighter, simpler Roborock and don't need plumbing-style dock automation.

• Choose the S8 Max Ultra if you want the most automated dock — auto refill and drainage, hot-water mop washing, hot-air drying and auto detergent — plus the strongest suction in this pair.
• Choose the Qrevo Edge S5A if you want a lighter robot with a multifunctional dock and Siri support and don't need the dock plumbed for refill and drainage.
