Roborock - Saros Z70

Don't buy the Z70. [https://lifehacker.com/tech/roborock-saros-z70-review](https://lifehacker.com/tech/roborock-saros-z70-review)

There is no perfect robovac.... but... I like the robots with split rollers, like the Roborock Saros line. These also have a removable tray, and I think the hardware is solid. But in reality, almost all premium robovacs and even the midtiers have these features (removable trays, etc).

I have a Z 70 I think it’s worth it. You can just turn the arm off if you don’t like it, but I think it’s cool. The mopping is incredible. Also hairs do not get stuck in the brush roller at all. The navigation is also really good Also, it’s nice to be able to remote in and use the camera whenever you need to The arm also has a camera so you can see high angles like check on the stove or see if you locked the door stuff like that. I think you should get it. It’s the latest and greatest also, the arm is always getting better every day.

I’ve noticed that it’s picking up things it didn’t when I first got it and it’s been consistently getting it in the basket better then before so yeah every time I run mine, I notice an improvement in the sorting.

I was torn between the S10R and the Z70, but I ended up going for the Z70 because of the robotic arm and honestly the suction power and obstacle avoidance are perfect. My place has a pretty complicated layout, but I never have to worry about it getting stuck anywhere.

Only 1 of the 3 new models has a vibrating mop. The flagship Saros Z70 uses rotating mops and so does the 10R. Vibrating mops are only effective depending on how much force they apply and how fast it can vibrate. Even Roborock advertises rotating mops to be superior to vibrating ones.

I'm not the person you replied to but I also have the S7+ MaxV Ultra for a couple years. It has the dock you're talking about and it's awesome. The app tells you when it's time to clean or do maintenance on any of the parts. Most commonly is cleaning the mop cleaning brush which just pops out, wipe the dirty water up with paper towel, clean the washable pop out filter and put the brush back in. Clean water tank lasts for about 4 days in my 1500sq ft. Dirty water would be close to 6 or 7, however if you leave it longer than a day or 2 it will smell when you dump it (dump it in the toilet as a protip). If you add about a shot glass of mouthwash to the dirty water tank after you empty it you can get 2-3 more days before it smells. I love our so much I just bought their new one with the mechanical arm. So excited for it to arrive.

Put in another vote for Roborock. I have their S7 Max V Ultra for like 2 years+ now. It runs every weekday while we're at work and it very rarely has a problem with our (hate to say it) quite cluttered house. There's socks, plates, forks, dog toys, kid toys, cables etc on the floor at any given time. It almost never needs help. I will say it doesn't like small dog bones that it can almost suck up cuz they get stuck. I like it so much I just ordered their new Saros Z70 (yes the one with the robot arm.) and will move the S7 downstairs. FYI they are currently doing their 11th anniversary sale and there are some solid deals.

The Z70 launched in Singapore a month ago and I placed an order once I saw it. The unit came two plus weeks ago and unfortunately bricked during firmware update. It took the service centre a week plus to troubleshoot and replace the motherboard. Finally received it today! Wondering if anyone else received their unit and would like to share what items are you tried to pick up with the robot arm?

The Saros Z70 dodges all items on the floor so far. Classifies many as pet waste whether they are or aren’t. Now that I can train it with pics of specific cat toys, it does usually identify them. It will avoid them and not sort them with the arm, except for just one that looks like a bee or insect. However, I always go through the house and prep before vacuum/mopping. I had to clean up three times older iRobot vacs from pet waste and swore I’d never do that again! The Z70 in the quietist mode doesn’t bother my three cats. The unit does a fantastic job so far on hard floors and avoiding objects I missed. It isn’t picking up and sorting stuff like I would like. One day it will likely sort all the cat toys, but right now it doesn’t. Slippers, socks it does. That one toy, yes, does a great job. The potential is there. I clean the unit once every couple of weeks. I use filtered water in the clean water tank. Have had no real issues since I got it in late April from an early Bogo sale in February or March. Once I’ve prepped the house, I don’t mind leaving it unattended.

The Z70 has "22,000 Pa" vs my S5's "2,000 Pa" - on paper the Z70 should crush it. But when I put my hand on the exhaust, way more air flows out of the S5. Turns out **Pa is just pressure, not airflow volume**. It's like comparing a leaf blower to an air duster - the leaf blower moves piles of leaves with lower pressure but high volume, while the air duster has crazy pressure but tiny volume (great for keyboards, useless for leaves). For actually picking up dog hair and debris, you need **air volume** (CFM) to lift and transport stuff into the vacuum. According to Vacuum Wars testing, the Z70 only moves 16 CFM while my S5 moves around 17-18 CFM - so my older vacuum actually has better airflow despite the lower Pa rating. So Roborock basically chased higher Pa numbers for marketing but sacrificed the airflow engineering that actually matters for cleaning performance. My 7-year-old vacuum has better real-world design than the newer model.

Picked up the Z70 not too long ago and I'm still kinda surprised by it. This thing's way stronger than my last vac, suction's plenty strong, that little robotic arm works great around my place and honestly feels worth paying for.

My advice is to never buy a robot vacuum at full price there are always deals, so it's worth waiting. The Matrix 10 Ultra is an interesting device, but I wouldn't get it. I think it has potential but in it's current state it's almost pointless, kind of like the Roborock Z70 with its robotic arm. It also takes forever to clean since it has to swap pads, wash them, etc. It's a dumb product, although not as dumb as the Z70. As of today, the robots I would get are the Dreame Aqua10 Ultra Track and the Ecovacs X11 OmniCyclone. Maybe also the Eufy E28 (Im a bit unsure about this one), but that's mainly because of how easy it is to maintain the roller and the dock. But I would generally recommend basically any good robot that has a massive price gap. Between the top models as they are like 90% as good as the top end for 50% the price. Also, don't get scammed when deal hunting! Always use sites that show price history so you can see if you're actually getting a deal.
