Pros & cons
Roborock Saros Z70
- ✓OmniGrip mechanical arm genuinely picks up and relocates small objects like shoes and fabric before cleaning — a real industry first
- ✓Best-in-class obstacle avoidance in independent testing (22/24 score versus a 16.6 category average)
- ✓80°C hot water mop washing plus 22mm auto mop lift keeps mopping and carpet cleanly separated
- ✓Ultra-slim 3.14in body still slides under most furniture despite the added arm hardware
- ✓Roborock's most mature app, with SmartPlan 2.0 adaptive routines and a built-in voice assistant
- ✗The mechanical arm only successfully grabs and moves an object about half the time in testing, and recognizes just three object categories
- ✗Smallest dustbin Roborock has shipped at 180ml, meaning more frequent dock empties even with auto-emptying
- ✗Carpet deep-cleaning (67% vs. 75% average) and pet-hair pickup on carpet (83% vs. 92% average) both tested below category norms
- ✗Near $2,000 at full retail — reviewers note the cheaper Qrevo Edge or Saros 10R clean nearly as well for hundreds less
- ✗First-generation arm mechanism, so there's no multi-year reliability record yet
Roborock Qrevo Edge 2
- ✓94% embedded-sand removal on carpet in independent testing, well above the 78% category average
- ✓Mopping score roughly double the category average, among the best tested
- ✓Pet hair pickup improved to 89.5%, up from 80.5% on the original Qrevo Edge
- ✓Notably fast navigation and cleaning runs, about 16 minutes quicker than category average
- ✓176°F hot water mop washing dock with up to 65 days between manual dust emptying
- ✗Obstacle avoidance is a genuine step backward — 14/24 in testing, below both its predecessor and category average
- ✗240ml dustbin is smaller than the original Edge (325ml) and the category average (377ml), risking overflow with bulky debris
- ✗Roughly $1,300 street price puts it squarely against flagship competition
- ✗Manufacturer doesn't publish noise level or water tank capacity for this model
