A well rounded flagship for homes with pets and mostly hard floors. Vacuum Wars measured strong suction, no hair wrap and good obstacle avoidance, and its retest after a firmware update rated the mopping well above average. Tom's Guide was less impressed with edges and corners, and the 3.74 in body will not fit under the lowest furniture.

One of the better all round Roborocks for carpet and pet hair, and the slim body reaches under low furniture. The trade offs are a low 20 mm threshold limit and below average obstacle avoidance. Skip it if your home has tall thresholds or lots of floor clutter.

- Vacuum Wars (3.88/5): Lab tests found 84% sand removal from carpet, 88% flattened pet hair pickup, 0% hair wrap and 20 of 24 obstacles avoided; a retest after a firmware update put mopping well above average, but the studio vacuum and mop run lasted only 38 minutes. Source
- Tom's Guide: Picked up 100% of kitty litter on both floors, 100% of pet hair on hardwood and 80% on carpet, but only 30% and 20% of cereal; reviewer said edges and corners need manual cleaning and it does not live up to its price. Source
