Roborock
Qrevo Curv
Confirm the current dock bundle. The refill-and-drain version is a different, region-limited product.
Pros
- • Hot-water mop washing and auto-empty are in the standard dock story.
- • Anti-tangle brushes are the practical feature for hair, which is why this class exists.
- • No novelty arm in the price.
Cons
- • 103 mm tall, so it will not go where the 79.8 mm Z70 will.
- • Suction, hair, and bacteria figures are manufacturer tests. Read them as ratings, not as our lab results.
- • The dock is large, and the plumbed version is easy to confuse with the standard one.
Roborock
Saros Z70
Device Radar’s review used $1,599. Confirm the current bundle; the arm is why this one costs more.
Pros
- • 7.98 cm tall, which is the spec that gets it under more furniture.
- • The arm is a real mechanism on the product page, not a concept render.
- • Alexa, Siri, and Google Home are listed without requiring one phone brand.
Cons
- • Matter is described as a future update on the page used here.
- • The arm is slow and limited in Device Radar’s review. Price it as a mop first.
- • Flagship money. A Qrevo-class robot does the daily clean for less.
