How much does the Roborock Saros Z70 cost? And does it ever go on sale?

UPDATE: Sep. 4, 2025, 6:30 p.m. EDT This post was originally written in January 2025 and has been updated to reflect current pricing information for the Roborock Saros Z70, Saros 10, and Saros 10R. Each model has also since been tested at home, with my experiences documented below.

It's unlikely that many people had a robot vacuum with a whole-ass arm on their CES 2025 bingo card. But alas, Roborock gave us one: the Roborock Saros Z70, which costs $2,599 regularly. That's steep but expected, considering the current high-end Roborocks with no robotic limbs go for over $1,500-ish (a few hundred less if they're on sale).
Where can you buy the Roborock Saros Z70?
If you're in the market for a new robot vacuum — and are open to buying one on the more expensive end of the spectrum — you still have plenty of time to decide whether the arm thing is overkill even for you. The Roborock Saros Z70 began shipping in April 2025, and is currently available for purchase at Amazon, Best Buy, and Roborock's website. Roborock's site is the only place that has sported the Saros Z70's first big discount: It was $1,000 off for a few days in August and September.
What's so special about the Roborock Saros Z70?
The Roborock Z70 goes past the small obstacle avoidance technology that has become a navigational staple in the best robot vacuums, instead, bulldozing into obstacle removal technology. It performs such with a robotic OmniGrip arm that unfolds out of the top of the robot vacuum to grab the obstacle claw machine-style, and drops it in a nearby designated area. The live demo at CES 2025 showcased the Z70 putting socks into a basket.
I have since had the Saros Z70 in my home for several months, and was disappointed (but not surprised) that the robotic arm doesn't make your life much easier. The arm's pickup capabilities were advertised to cover four different types of obstacles and must weigh under 300 grams: socks, paper, small towels, and lightweight shoes (no pet toys yet). The arm does technically work sometimes — I've witnessed it successfully pick up sandals and socks — but other times, it completely misses or ignores obstacles altogether. The half-baked innovation had good intentions, but for now, is just another robot vacuum that is trying to do too much.

People more swayed by practicality than a hit-or-miss high-tech feature might find the bigger grab here to be the Z70's incredible 22,000 Pa of suction power. That's 12,000 Pa more powerful than the Roborock Qrevo Master, my favorite overall robot vacuum of 2024 that cleans with 10,000 Pa, and also beats the suction power of any Roomba I've tested by a long shot.
The Saros Z70 isn't the only new 2025 Roborock vacuum
Roborock also announced two more flagship robot vacuum and mop combos in the Saros line that are armless, making each a much more digestible price to the average household. Since this story's first writing in January, I was able to test both the Saros 10 and Saros 10R at home for several months. Both retail for $1,599.99 (in line with my original price prediction) but have been on sale for $1,299.99 toward the end of summer 2025. As it stands, I think the Roborock Saros 10R is the best robot vacuum you can buy currently.
Rather than relying on the rotating laser tower atop many robot vacuums alone to assess walls and furniture in the room, the Roborock Saros 10R maneuvers using dual-light 3D Time-of-Flight technology and AI-powered RGB cameras. That's fancy talk for more meticulous 3D mapping of your home and more precise detection of small obstacles that may be lying in the cleaning path — so even without the arm, this is still a big step up in the autonomous navigation department. The AI itself is also upgraded for more accurate, ever-improving recognition of the trickiest obstacles, including small toys and loose, unfolded cables. It just can't clean under them like the Z70, though that might be a no-brainer sacrifice depending on the price difference between the two.

Cleaning-wise, the Saros 10R cleans with 20,000 Pa of suction power, while the similar Saros 10 cleans with the same 22,000 Pa suction power as the Saros Z70. But to me, the biggest difference between the Saros 10 and Saros 10R is actually related to mopping — I compared both models head-to-head in my apartment to help you pick one.

Five burning questions we have for Alien: Earth Season 2

This summer, FX's Alien: Earth latched onto my brain like a Facehugger latches onto a new host.
Now, with the release of the show's Season 1 finale, you'd think that Facehugger would drop off and leave me be. You'd be wrong! Instead, the Season 1 finale leaves viewers with some major questions we'll be puzzling over until the show's potential return.
Here are the five biggest questions we have for Alien: Earth Season 2.
What does a Neverland run by hybrids look like?
Season 1 of Alien: Earth ends with the group of hybrids known as the Lost Boys in total control over the Neverland research facility. They've imprisoned Boy Kavalier (Samuel Blenkin), Kirsh (Timothy Olyphant), Morrow (Babou Ceesay), Dame Sylvia (Essie Davis), and Atom Eins (Adrian Edmondson). Now, with the adults out of the way, Wendy (Sydney Chandler) declares it's time for the hybrids to "rule."
But what will their rule entail? Will they stay on Neverland, or will they try to extend their authority to the rest of the world? Will they remain fast allies, or will they turn against one another and go full Lord of the Flies on their new island kingdom?
How will Weyland-Yutani and Alien: Earth's other corporations react to Boy Kavalier's plight?

By the end of Alien: Earth Season 1, Weyland-Yutani is closing in on Neverland in order to take back the specimens Boy Kavalier stole. But will Yutani (Sandra Yi Sencindiver) change tack when she realizes her rival is being held captive? Will she leave the island alone or try to stage a hostile takeover? Perhaps her priorities will change entirely, shifting from trying to capture the alien specimens to trying to perfect Boy Kavalier's revolutionary hybrid tech. Either way, her looming presence does not bode well for the newly independent hybrids.
Weyland-Yutani isn't the only other major corporation on the board in Alien: Earth, though. There are three other corporations we haven't truly met yet: Dynamic, Lynch, and Threshold. Could they be joining the party in Alien: Earth's future?

What's next for the loose orchid and eyeball aliens?
While the Xenomorph may be under Wendy's control, there are still several alien threats running wild on the island. In the Season 1 finale, the orchid alien (aka D. Plumbicare) revealed that it could turn into a floating, octopus-like creature and got loose in Neverland. I would not want to be walking around the island with that out there, that's for sure.
But that's not all: Alien: Earth's breakout star, the eyeball alien T. Ocellus, found a new host in the corpse of Arthur Sylvia (David Rysdahl). We've seen T. Ocellus take over a cat corpse and a human body, but now we get to see it go full zombie mode in what might be Alien: Earth's coolest development yet. But what's T. Ocellus's plan while in Arthur's body? Will it try to find a new, stronger host in, say, a hybrid? (And what would that look like?) Will it finally have a conversation with its biggest fan, Boy Kavalier? And how in the world will Dame react when she sees her beloved husband with a massive new eyeball and a burst-open chest? Bring on the zombie shenanigans!
Will the Xenomorph continue serving Wendy, or will it rebel?

For now, Wendy and her Xenomorph seem pretty tight. But what happens if the Xenomorph goes through a rebellious teenage phase and decides it doesn't want to serve its human mother figure anymore? Could the hybrids lose their grip on Neverland if the apex predator at their disposal decides to turn on them?
Wendy's Xenomorph also isn't the only Xenomorph on the island. There's also the specimen that burst out of Arthur's chest. As it grows, will it become territorial with Wendy's Xenomorph, or will it join the hybrid-Xeno family and view Wendy as its queen? If so, what are the odds Wendy tries to build a whole Xenomorph army?
How will Alien: Earth tie back to Alien?
The question hanging over any prequel is "how will this tie back to the original?" and with Alien: Earth, that question is especially pressing, given that it takes place two years before the events of Alien. By that point, there are no mentions of hybrid technology, nor are there any mentions of them in the sequels. So what will happen to the hybrids between then and now to render them obsolete? It's a daunting question, but it's one that Alien: Earth will certainly have to contend with as it closes in on the original films.
Alien: Earth is now streaming on Hulu.

Alien: Earths game-changing ending, explained

After eight episodes of terrifying new creatures, Alien homages, and existential questions about the future of humanity, Alien: Earth Season 1 has come to a close. And what a close it was.
The finale, titled "The Real Monsters," flips the power dynamic that's been in place for the entire season. By the end of the episode, the hybrid Lost Boys, led by Wendy (Sydney Chandler), have gained total control over their keepers, including Boy Kavalier (Samuel Blenkin) and Dame Sylvia (Essie Davis). This power shift has been in the cards since Alien: Earth's first episode, but how do we get here? Let's break it down.
Alien: Earth's hybrids finally realize how strong they are.

Credit: Patrick Brown / FX
From the first moment Alien: Earth introduces Wendy in her super-strong, super-fast, super-durable hybrid body, it's clear that she and her fellow Lost Boys could absolutely wreck Prodigy's Neverland security team if they wanted to. That idea doesn't cross their minds, though. Instead, the Lost Boys are still children in consciousness, and they believe Neverland to be a safe paradise for them.
However, this idea erodes over the course of Alien: Earth's first season, as the Lost Boys lose confidence in the people they've been told to trust. They're endangered and experimented on. Nibs' (Lily Newmark) traumatic memories were manipulated. Isaac (Kit Young) died while tending to the alien specimens. Morrow (Babou Ceesay) threatened to kill Slightly's (Adarsh Gourav) family. Each horrifying incident wears away at the Lost Boys' childlike innocence, turning the idyllic Neverland into a hell on Earth.
Ironically, these incidents only increase the Lost Boys' feelings of powerlessness, even though they're the most powerful beings on Prodigy's remote island. But it's also in one of those scenes of powerlessness — when Prodigy forces corner Nibs, Wendy, and her brother Joe aka Hermit (Alex Lawther) on their escape boat in episode 7 — that the Lost Boys begin to realize their power. Nibs fully rips a soldier's jaw off, leaving Hermit to shoot (but not kill) her. Here, a horrified Wendy learns two things. First: Humans, including her brother, are terrified of the hybrids. Second: They have good reason to be. The hybrids are extremely dangerous. So why not embrace that?
That's the realization Wendy comes to in Alien: Earth's Season 1 finale. "All this time, we've been afraid of them," she tells the Lost Boys as they sit trapped in a Neverland cage. "But I think they should be afraid of us."

Embracing the Neverland staffers' fear of them is the final stage in the Lost Boys' loss of their childish innocence. Or, in terms of Boy Kavalier's relentless Peter Pan references, this is them finally "growing up." However, that's exactly what the Prodigy founder and the rest of Neverland don't want to happen. As Wendy puts it, "We're all in this cell because we can't be kids anymore, but they won't let us be adults."
Nibs has another suggestion for what they are, one that's especially fitting after seeing the graves of their dead human bodies. "We're all ghosts," she says.
So what do these ghosts do? They turn Neverland into a haunted house, with Wendy using her in-built connection to the facility to manipulate video feeds, elevators, and doors to terrify every last soldier and scientist. Of course, having a Xenomorph at your beck and call helps too.
The entire episode serves as both a liberation for the Lost Boys and an identity crisis for Wendy, otherwise known by her human name, Marcy. She tells her brother, "I don't know what I am. I'm not a child. I'm not a grown-up. I'm not Marcy. I'm not Wendy. And I can't be what everyone wants me to be."
(Earlier in the season, Joe even questions whether Wendy truly holds his sister's consciousness, yet another blow to one of the pillars of Wendy's identity.)
Wendy's statement reflects the binaries in the world of Alien: Earth. Child and adult. Human and synthetic. Hybrids exist somewhere in between, blurring boundaries and creating a new kind of personhood. Wendy and the Lost Boys have spent the entire series having not just new names but entirely new identities imposed on them by exterior forces. Now, they get to make their own. Fellow hybrid Curly (Erana James) embraces her former name, Jane, as Wendy reminds each of the Lost Boys of theirs — a move the late Isaac, formerly Tootles, only enjoyed for an afternoon.
Wendy's identity crisis also explains her affinity for the Maginot aliens, whom she considers "honest." These creatures are wholly themselves, unlike liars such as Boy Kavalier. As Wendy points out, he considers himself Peter Pan, but he was never truly a boy. He was always a "mean, angry little man," just like his abusive father. Ouch. I'm not sure he'll be picking up a copy of Peter Pan any time soon after that.
"Now we rule."

"The Real Monsters" ends with Wendy and the Lost Boys holding all of the authority figures in their lives hostage in the same cage they were formerly incarcerated in, prompting Wendy's declaration that, "now, we rule." Even Kirsh (Timothy Olyphant), their Prodigy synth senior, and Morrow, their cyborg antagonist, now answer to them.
The hybrids finally taking control is undoubtedly worthy of Alien: Earth's last hard-rocking needle drop. But it's certainly not the end of the Lost Boys' story. After all, the Weyland-Yutani forces are still encroaching on the island with numerous Prodigy forces still left, hinting at more conflict ahead. Plus, the alien orchid is loose, and T. Ocellus has found a new host in the chestburst corpse of Arthur Sylvia (David Rysdahl). That's a lot of threats for these still-young hybrids to deal with. How will they be able to fight off their enemies and learn how to rule their island?
That question of what it will look like for hybrids to "rule" hints at an intriguing new literary reference point for a possible Alien: Earth Season 2. If Season 1 was the Lost Boys growing up in the style of Peter Pan, then Season 2 might just see them learning to survive on an island in the vein of Lord of the Flies. With that in mind, who's Piggy, who's Ralph, and will the Xenomorph's head somehow wind up on the end of a pointy stick?
