Our verdict
The Saros Z70 tops the lab pet hair rankings and adds smart obstacle handling that suits busy pet homes. It dropped to around $950 in October 2026 sales, which makes it more realistic than at launch.
What we like
- RTINGS names it the best robot vacuum for pet hair it has tested (Aug 2026)
- Uses AI to recognise certain objects, according to RTINGS, so it can steer round or move them
- Robotic arm can move light items such as socks out of the way
- Dock empties dust for up to about seven weeks
- Can pick up socks, light sandals, tissues and small towels
- Excellent navigation and cleaning, per TechRadar
What to know
- Expensive even on sale
- The arm is a novelty for many owners, so you pay for a feature you may rarely use
- RTINGS' full pet hair breakdown sits behind its site, so check scores before buying
- TechRadar found automatic pick-up unreliable
- Very high list price
