A robot vacuum that tidies up before it cleans sounds like science fiction, but Roborock has been selling one since 2025. The Saros Z70 has a folding mechanical arm that can pick up socks, slippers and tissues and move them out of its way, which makes it exactly the sort of gadget people search for in the run-up to Christmas. The awkward answer for UK shoppers is that you can find it on British shop pages, but right now you cannot buy a new one from an authorised seller. Here is what it does, what it costs and what we would buy instead.
What is the Saros Z70?
Roborock unveiled the Z70 at CES in Las Vegas in January 2025 and put it on sale in the US and Australia that May. The company calls it the first mass-produced robot vacuum with a foldable five-axis arm, which it brands OmniGrip. When the arm is not needed it folds flat under a hatch, leaving a robot just 7.98cm tall, low enough to slide under many sofas and beds.
Underneath, it is a flagship robot vacuum and mop. It has 22,000Pa of suction, two spinning mop pads (one swings out to reach skirting boards), a chassis that lifts itself over thresholds up to 4cm high, and an all-in-one dock that empties the bin, washes the mops in 80°C water, dries them with warm air, adds detergent and cleans itself.
What can the arm really do?
On paper, quite a lot. Roborock says the robot spots objects on its first pass, moves the ones it can lift and then goes back to clean the gaps. It can handle socks, sandals, crumpled tissues and towels weighing under 300g, and a weight sensor stops it trying to lift anything heavier. You can teach it up to 50 extra objects in the app, drive the arm yourself by remote control, and switch to a camera on the arm for a higher view of your home. The arm features are switched off by default, and there is an emergency stop button and child lock.
Independent testers have found it less handy in practice. TechRadar's reviewer spent two weeks with it and could not get a fully successful autonomous tidy-up. In dim light it mistook two sandals and a sock for carrier bags, it fumbled a strappy sandal, and on one run it picked up a pair of socks only to put them down about 14 inches away. Driving the arm manually through the app worked well, which the reviewer thought could help people with limited mobility. Good Housekeeping UK found the arm could move light items such as a tissue or slipper but struggled with heavier ones. The cleaning itself won strong reviews; the arm, TechRadar concluded, is "not quite there yet". Roborock has promised more objects and improvements through software updates.
UK price and availability
Roborock's UK online store lists the Saros Z70 at £1,599 in black or silver, below the £1,799 list price quoted at launch. But when we checked on 1 November 2026, both colours were marked unavailable. Roborock's UK product page also points buyers to Amazon UK, where the silver model said: "Currently unavailable. We don't know when or if this item will be back in stock." The independent UK review site Bot 'n' Brush reached the same conclusion on 16 October, finding no confirmed authorised UK stock and no active listings on PriceSpy UK.
So the honest answer is: officially yes, practically no. The Z70 is a UK product in principle, but there is nowhere to order a new one from Roborock or an authorised retailer today. Roborock UK's Black Friday sale, promising up to 39% off its range, starts on 10 November, so it is worth watching whether stock returns, but we found no announcement that it will.
Should you import one?
The Z70 is far cheaper in America, where Amazon and Roborock have sold it for $999.99 in recent deals against a list price of $2,599.99. That is about £745, which is tempting, but we would not do it. Anything worth more than £135 sent to Great Britain attracts 20% import VAT on the price plus postage, and Customs Duty at the UK Trade Tariff rate, with courier fees on top, so a large robot and dock would cost a good deal more by the time it reached your door. It would arrive with an American plug and power supply, and you would need to be certain a dock that heats water to 80°C is rated for UK 230V mains. You would also give up the two-year warranty and 30-day free returns that Roborock's UK store offers on its vacuums. A grey import is a risky way to save money on a product that still depends on regular software fixes.
What to buy instead
If the arm is the whole point, wait. Arm-equipped robot vacuums are at an early stage, and TechRadar suggests holding on for software updates or a later generation. If what you really want is a superb, slim, self-cleaning robot vacuum, you can have one now for much less. The Z70's arm-less sister, the Saros 10, offers the same 22,000Pa suction and low 8cm profile, and was £649.99 in black at Roborock UK on 1 November, down from £1,199.99. The newer Saros 20 Set, the premium pick in our best robot vacuums guide, was £899 at Roborock UK (down from £1,309) and is sold on Amazon UK by Roborock's official UK store. For most homes, the Eufy X10 Pro Omni, at around £450 in our guide, remains our overall favourite.
Our verdict
The Saros Z70 is a real preview of where home robots are heading: a machine that changes the room rather than just moving around it. But in the UK it is effectively unavailable today, and even where it is sold, reviewers say the clever part does not yet work reliably on its own. Do not chase one through grey importers. Buy a Saros 10 or Saros 20 if you need a robot vacuum this Christmas, and come back to arm-equipped models when they are both in stock and properly finished.
