## Summary

The video is a hands-on review of the Roborock Saros Z70, the first robot vacuum with a robotic arm. The reviewer tests its ability to pick up and sort objects like shoes, socks, and toys, highlighting both its impressive capabilities and current limitations. The video also covers the vacuum's cleaning performance, hardware design, and smart home integration.

### Key Points

- **Introduction to the Z70** [00:18] — The video introduces the Roborock Saros Z70, a robot vacuum with a claw arm, and sets up the review context: testing it in a home with three kids.
- **Manual Arm Control** [00:46] — The arm can be manually controlled via phone, with four movements: rotate, up/down, forward/backward, and open/close. It includes a camera and light for visibility.
- **Arm Strength and Safety** [02:09] — The claw can pick up items up to 300g, but can handle heavier objects manually. Safety sensors prevent pinching, and the arm is strong but won't crush fingers.
- **Automatic Object Pickup** [03:05] — The vacuum automatically picks up socks, shoes, and toys, moving them to a storage bin or designated spot. It can sort shoes into a shoe pile.
- **Beta Software Limitations** [06:41] — The Z70 runs beta software, so there are hiccups. Automatic pickup doesn't work on carpet, and it only grabs certain shoes (like sandals). The manual is blank.
- **Cleaning Performance** [08:53] — The vacuum has 22,000 Pa suction, dual spinning mops that detach, and a Freeflow main brush that cuts hair. It uses StarSight instead of LiDAR for mapping.
- **Future of Smart Home Tech** [10:41] — The reviewer believes the Z70 represents a new era of smart home technology, despite growing pains, and that it paves the way for future innovations.

### Conclusion

The Roborock Saros Z70 is an impressive and fun robot vacuum that effectively picks up and sorts objects, though it has some limitations due to beta software. It represents a significant step forward in smart home robotics, even if not perfect yet.

## Transcript

organizing the shoes around my house all by itself. But is it even any good at picking things up? And is the future of robot vacuums a claw arm? Well, I'm
if it can handle the wrath of my three little kids. This is the Robo Rock Soros Z70. You know, the robot vacuum with the claw arm. And I've been so excited to try this out in my house ever since seeing it at CES. I partnered with Robo
Rock for this video, but I'm still going to show you the good and the bad. So, yeah, enough of all this talk. Let's try out this robot arm. At CES, Robbo Rock said we would be able to use our phone to manually control the arm. You know,
like a little remote control. So, of course, the first thing I did when I set up the Z70 was use that claw arm. It's surreal watching an arm pop out of the robot vacuum in my own house. You know, in the movie Alien when it pops out of
him in the dinner scene, it's like that. It's crazy. Of course, there are the standard remote controls to drive the vacuum around, but there are now arm controls, too. It has four different movements. Rotate the claw, move the arm
up and down, or move it forward and backwards. Lastly, the ability to close and open the claw. I was using it with my kids and it was so much fun. Cleaning up the toys is like playing a video game. We were fighting over who gets to
game. We were fighting over who gets to clean up. Can I have a turn? No. Ally, they're not sharing with me. There's a camera on the end of the arm so the vacuum knows what it's grabbing. I can also change that camera view while
controlling the arm. It's pretty sweet. Plus, it comes in handy to check on the previous Robo Rock vacuums when we're out of town, and it comes in clutch. So, this extra camera angle on the arm is a great bonus. Not only that, but there's
a light on the arm, too. So, seeing in the dark is no problem at all. The claw is actually pretty strong. It can pick up items up to 300 g. And I was curious to see if I could manually pick up heavier objects, and it could. So, the
arm is stronger than Robo Rock gives it credit for, but it won't crush your finger. I tried. Dad, make it pinch your finger. No. I triple dog dare you. Well, that's a slight breach of etiquette. Fine.
Of course, there are sensors to keep everyone safe. There's one on top of the vacuum to stop the arm from popping out. And there are sensors on the arm joints, so if something is getting pinched between the folding arm, it will stop. I
also tested this, and look, I still have all my fingers, so I'm not worried about it being dangerous or on my three little kids. And the hardware also feels very solid. Robbo Rock says the arm only takes up 10% of the vacuum, so they were
still able to fit everything in here. There is one main thing that Robbo Rock did not do on the Sorrow Z70 that they did do on the Sorrowos 10 and 10R. And I'll get to that in a minute because first we have to test how good the arm
is at automatically picking up shoes, socks, and anything else around the house. One of the biggest criticisms I hear about a vacuum with a robot arm is, "I already clean up before my vacuum goes around." And that's a completely
valid point. I also try to clean up before my vacuum goes around. But I have three kids and one of them is very cute, but has a personal mission to leave every pair of shoes and socks she has around the house. I kid you not, at any
given point during the day, there's about 10 pairs of shoes and 10 pairs of socks scattered around the house. And this is after us asking her to clean up just a losing battle. And even though Robbo Rock vacuums have been getting
better and better at object avoidance, they're not perfect. Sometimes it recognizes a sock and it avoids it, but then it bumps into something else that pushes the sock into the way and then it jams on the main brush. It's super
frustrating. Well, the Z70 has a much better approach, so it's much less likely to get stuck. When it starts cleaning and it spots a sock, it immediately grabs it and moves it to a safe spot. That way, it doesn't get too
close to the sock and accidentally gets stuck. So much better. Robo Rock provides a storage bin with a vacuum, and you can set where it is on the map. Then, the vacuum will put the socks and tissues in the storage bin so it's
safely out of the way. It's pretty cool that it can just automatically do this all by itself. If the storage box is in the corner of your house, it can take a while for the vacuum to bring the sock all the way to it. So, I would think
central location. And if you don't like how the storage bin looks, you could just have it drop it off in a certain spot in your house. After the vacuum is socks and tissues out of the way, the vacuum does a follow-up cleaning. Start
follow-up cleaning. where it moves the shoes a short distance to a spot where finishes cleaning where the shoes were. This is great because it doesn't take a lot of time to move the shoes and it gets the entire floor clean. But the Z70
takes things to another level and it will sort certain objects on the ground like shoes for you. That's right. It will take the shoes and carry them to will take the shoes and carry them to the shoe storage zone aka the shoe pile
in the house. So instead of nagging my daughter all day to put her shoes away, the vacuum will just handle it. It's insane. We still have our kids do chores around the house and learn responsibility, but I'm not going to
complain if a robot is going to do annoying tasks around the house that no one wants to do. What's really crazy is that it can pick up my kids toys and put them away from me, too. What? It almost feels wrong seeing this little doll
being carried away with this claw arm. But I'm so happy a robot is finally picking up my kids toys for me and putting them away. I know someone right now in the comments is typing, "Wow, your kids are never going to learn how
to pick up after themselves. The robot is always doing it." Well, these toys are for my daughter who is two, so yes, mom and dad need a break. And if you have a dog with a lot of dog toys that get left out, the Z70 should also be
able to pick up a lot of those, too. The vacuum only picks up the soft stuffed throws the toys with everything else like the socks and tissues. Eventually, Robbo Rock says it will be able to sort different types of items in separate
storage areas. So, that will be pretty sweet, but we're pretty close to being able to have a robot like Rosie from the Jetsons automatically putting things away for us. I want to point out that this Z70 robot vacuum is running beta
software, so there are some hiccups I've run into. You might be like, "Reed? If you run into any issues, just look at the manual." Well, do you want to see the manual? Check this out. It's just a bunch of blank pages. Obviously, they
sent me the robot vacuum before the manual is finished. Like I said, beta software. And this vacuum doesn't even come out for another month or so, but I want to share a few of the limitations that I ran into at the time of filming.
And obviously, things could change by the time it's released. First is the automatic pickup does not work on carpet. I think analyzing fabric items like a sock that it's on carpet could be difficult. Again, this could change, but
that's where it is right now. The other thing is the arm will only grab certain shoes, mainly sandals since it's easy for the arm to grab it. And even though it doesn't grab tennis shoes automatically right now, no items that
physical ability since I've done it with the manual controls. Robok says the list of items that it can pick up will grow with software updates. It's actually pretty interesting watching the vacuum analyze the shoe and then position
itself behind the shoe to grab it easier. Honestly, it's incredible seeing it in person. But as you can imagine, the arm sometimes misses when trying to grab a shoe or sock. If it does miss, it will try again. But I have seen it end
up failing on a shoe than it's been able to pick up before. The vacuum, for some when it was carrying a shoe around the house. I think the object avoidance sensitivity is turned up too high while carrying something with the arm and
sometimes it didn't make it to the storage area, which is weird because the shoe right before this got stored completely fine. This is brand new technology and we've never seen anything quite like this in a house before. So, I
think it would be unrealistic to expect the robot to be perfect every time right now. Oh, and Robo Rock now supports Matter. It didn't seem like it was working at first, but then I updated my Matter controller, which is the Apple
TV, and then it worked. It had more functionality than I thought it would have, like I can automate what room it cleans when all the phones are away. Awesome. The Z70 hardware is great, and it's really good about picking things up
off the ground. And any little bug that I ran into could easily be fixed with firmware updates, which I'm sure Robbo Rock will keep fixing because it's pre-release software. For the sake of not making this video an hour long, I'm
cleaning highlights. The suction power can go up to 22,000 Pascals, so it has plenty of power to clean your carpets and floors. There are dual spinning mopping. And the mops can also automatically detach in the dock if it's
just vacuuming. The vacuum can lift up to not get stuck, and it has star sight instead of lidar to map out the house. I've talked about this star site before and I still prefer over LAR. For mapping, it's pretty much the same, but
it's more accurate at detecting objects to not get stuck. So, I like that. Plus, without a little LAR sensor on top, it keeps a really slim profile to go under furniture. Of course, it has a self-cleing dock that can wash the mop,
auto empty the vacuum dust bin, and add cleaning solution to the mop water. As I mentioned earlier, Robbo Rock did something different on the Z70 compared with the other Soros vacuums. Instead of the Duo Divide, they added the Freeflow
main brush. It has these little grooves that can cut hair as the brush spins since there's a little blade that moves back and forth, similar to an electric razor. Even though the Duo Divide has a 0% tangle rate, Robo Rock went with this
design instead so they could fit the arm inside the vacuum. The side brush is similar to the other Soros 10 and 10R. It can lift up to be tucked away if needed, extend out to clean the corners, and it does a great job at not getting
hair stuck in it. It's impressive how well the Z70 cleans, especially since there's a whole arm stuffed in there. So, now that you've seen the Z70 in action, do you think a robot vacuum with an arm is the future? I think we're
entering a new era of smart home technology. Things like millimeter wave, AI and the voice assistants, and new robotic arms doing chores in the house. that we can do now that were not possible a few years ago, but there are
some slight growing pains as this new technology matures. Of course, I wish every brand new technology worked perfectly right away, but it doesn't. It's still fun seeing companies push the limits with technology to move things
forward. Even if you're not an early adopter to brand new tech, like a robot arm popping out of a vacuum, it could still pave the way to something you end up getting down the road. The Rubarok Rock Z70 is still an amazing robot
vacuum. It's so much fun to remote control. It's almost magical watching it pick things up off the ground and it's really good at cleaning the floors. I have links in the description to check out more. And thanks for watching.
