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 CurvX
- ✓0% hair tangling in independent testing versus a 28% category average — genuinely tangle-free in practice
- ✓92% debris removal on deep carpet, tying for third place out of over 200 robot vacuums tested
- ✓20/24 obstacle-avoidance score, a real step up from earlier Roborock generations
- ✓Retractable LiDAR drops to a 100° rear view for cleaning under low furniture
- ✓One of the best-reviewed apps in the category, plus strong marks for Roborock customer service
- ✗Measured airflow runs below the category average despite the 22,000Pa headline suction figure
- ✗Dustbin is small enough that pet-heavy homes will be emptying the dock multiple times a week
- ✗Uses more mop water than average on the low setting (testers saw no streaking, but it's a heavier water user)
- ✗Manufacturer doesn't publish battery-free dimensions, weight, dustbin capacity, or noise level for this model
