Pros
- RTINGS named it its best for pet hair among models it tested
- OmniGrip arm moves socks and small items
- Slim 3.14-inch body
- Hot-water mop washing and drying
- Much cheaper than the Saros 20
Cons
- The arm bay forced a smaller bin and brushroll, so more dock trips
- Long hair can tangle on the brushroll
- Reviewed says the arm sometimes fumbles objects and slows cleaning
- Smaller water tank
The Z70 is the pick for pet homes with clutter. It is a capable, well-priced Roborock, but long-haired shedders will do better with the Saros 20 or the Dreame L60 Ultra PE.
