Don't get me wrong, I love my dog. He's a really, really good boy. Maybe the best boy? I don't know, I haven't met all the dogs. Yet. But I what I don't love so much is his hair, which seems to shed at such a rate that it's astounding to me that he has any left at all.
It's been an absolute blessing, then, to have spent two years testing vacuums for TechRadar. I've tested all kinds of vacuums, at all kinds of price points, but the one I've clung on to is the Roborock Saros 10. It arrived in my home in spring 2025, and since then it has been a vital tool in my anti-hair arsenal. It gets sent out cleaning every night — and it hasn't let me down yet.

Despite being one of my most-used gadgets, I found it a little hard to recommend at list price (a cool £1.5K at launch). Since then it's attracted a number of deals, but none so good as the current Prime Day discount: the Roborock Saros 10 is now £699.99 at Amazon (down from an adjusted list price of £1,199.99). At that price, I would absolutely recommend it, as it's one of the very best robot vacuums I've ever used — and, like I say, I've used plenty.
Shoppers in the US get a slightly different deal: the Saros 10R is now $884.99 at Amazon (was $1,599.99). That's another all-time-low price on this sister model, which comes equally well reviewed (by another dog owner). These are amongst the very best Amazon Prime Day deals I've seen.
If you're suspicious of such a hefty discount, don't be. The robot vacuum market rattles along at a rate of knots, with multiple new models released each year (the two bots showcased here have officially been replaced by the Saros 20 and Saros 20 Sonic), That means models like this might be considered old news, even though they've only been around a couple of years.
The rate of appreciable improvement has slowed, though, so while the specs in the newest models might be technically better, you'll likely struggle to see much — if any — difference in the performance. That's true in the case of the Saros 20, which I also tested.
What's so good about the Roborock Saros 10?
Why do I love the Roborock Saros 10 so much? It's an ultra-capable all-rounder that requires minimal effort and maintenance from me. The vacuuming is efficient and effective, and the navigation and object avoidance is reliable — even when faced with the complicated corner of my kitchen that includes a thin rug, a table and multiple dining chairs, and also acts as the dog's preferred toy discard area. The mopping is also effective and thorough, clearing pawprints and smudges with ease.
The dock is also a standout. It auto-empties the dust cup, and has enough oomph that I've never experienced a hair blockage during this process (not true of all self-empty robovacs I've used). It'll also top up the onboard water tank from its larger dock reservoir — adding the right amount of cleaning fluid as it does so — and clean and dry the mop pads when it's done cleaning. Opting for a slightly older flagship model is my #1 tip for saving money when shopping for a robot vacuum.
What's the difference between the Saros 10 and 10R?
The Roborock Saros 10 and 10R are very similar in terms of specs and performance, but there are a couple of design differences. The first is that the 10R uses a different navigation system; one which doesn't require a raised LiDAR puck. So instead of a puck that can pop up and down, there's no puck at all. On test, we found this robovac navigated just as accurately as the 10. Both bots are the same height, and both are equally good at cleaning under the sofa.
The second difference is the mop pad style. While the 10 has a vibrating, D-shaped pad, the 10R boasts two, spinning pads. If I had to choose, I'd say I slightly prefer the dual mop-pad setup, but there's barely anything in it. In terms of wet cleaning, neither of these robot vacuums will let you down.
