Roborock S7 MaxV Plus vs iRobot Roomba j7+: which one to buy?

Two of the biggest names in the robot vacuum world go head-to-head this time around. The Roborock S7 MaxV Plus versus the iRobot Roomba j7+. These robot vacuums are in somewhat different leagues, but it still makes sense to compare them. Since they both target pet owners, even though the Roborock S7 MaxV Plus is a few hundred more than the Roomba j7+. But we think it would be unfair to compare the self-draining version of the Roomba j7 to the self-draining version of the S7 MaxV.

And the reason we’re not comparing the S7 MaxV Ultra here is that it’s currently out of stock and also almost twice the price of the Roomba j7+, making it less likely for customers to compare the two.

So without further ado, let’s start comparing.

Roborock S7 MaxV Plus

The Roborock S7 MaxV is probably the best robot vacuum that Roborock has ever made. However, it’s better with the Ultra docking station, but it’s still a few hundred dollars. But the Self-Dumping Dock Plus is still very good.

It’s not a cheap robot vacuum, which costs $859 (without the docking station), but it has a lot going for it. Let’s start by vacuuming. It has a suction power of 5100 Pa, which is currently the highest on the market. What does this mean in real life? Well, that means any dirt, dust, and other debris in the carpet of your floors will be easily picked up. Even more so than most other robot vacuums.

There’s also the stereo camera on the front, with ReactiveAI 2.0. This allows the S7 MaxV to move forward and dodge all obstacles on the ground. This includes things like dog toys, charging cords, shoes, scales, and even pet waste. It also does a pretty good job of dodging those obstacles, which is always nice to see.

Then there is the cleaning. Roborock has added Sonic Mopping and VibraRise from the S7 it released last year. Which allows it to do an excellent job of cleaning up those dried-on messes. And with VibraRise, that means it can lift the mop off the floor and clean your carpet in the same cycle. Instead of other robot vacuums that require you to remove the mop to clean carpeted rooms. Which I absolutely hate, having used the S7 and S7 MaxV for over a year.

Finally, the biggest addition to the S7 MaxV’s cleaning feature is that you can use soap now. You’re limited to soap made specifically for this robot vacuum, but it’s better than just using plain water.

Self-emptying docking station

The Roborock S7 MaxV offers several docking stations that you can choose from. You can choose whichever comes in the box which is quite annoying as it just charges it. Or you can choose the Auto-Empty Dock which launched with the S7 in 2021, or the Ultra Dock which launched with the S7 MaxV. The Ultra Dock is my favorite dock, but for this comparison we’ll be using the standard Auto-Empty Dock, as its price and features are closer to iRobot’s.

This Auto-Empty Dock is actually really nice to have. So there are towers, basically. One has a filter that debris passes through, before moving to the other tower and entering the dust bag. This is because it has a HEPA filter inside, which makes it ideal for allergy sufferers. It can hold up to about eight weeks of dirt and debris before it needs to be emptied.

The great thing here is that you don’t need to purchase the dock along with the robot vacuum. Indeed, Roborock actually sells the self-emptying docking station and the Ultra docking station separately.

iRobot Roomba j7+

The Roomba j7+ is iRobot’s latest robot vacuum, which was unveiled in the fall of 2021. It’s quite an interesting model from the company, and was apparently designed to solve one of the major problems faced by its clients. And it was the fact that it would run over pet waste and spread it all over the house. With the Roomba j7+, this is no longer a problem.

Much like Roborock, iRobot uses a camera on the front (although there’s only one, not two like the S7 MaxV). This camera is used to identify and avoid obstacles. In my review a few months ago, I found it did this very well. He never needed a rescue either. It can also automatically suggest areas to avoid, which is pretty cool.

In fact, iRobot is so safe it won’t waste your pet that there’s a POOP Guarantee.

On robot vacuums, I feel like design doesn’t matter that much, but the whole package here is very modern. The self-emptying docking station is also very small and modern, so it doesn’t look like an eye sore in your home.

Like Roborock, the Roomba j7+ also uses rubber brushes. iRobot did it first. But instead of just one rolling brush, it uses two. And while it’s not as powerful, it seems to clean about as well as the S7 MaxV. This is largely because the j7+ has two brushes which are very close together and very close to the ground. It is therefore able to pick up more dirt and debris.

The main reason this works better is that iRobot doesn’t use this opening to empty the trash can. Roborock uses the rolling brush opening to suck dirt and debris from the trash can into the dock. iRobot has another opening that it uses and works a bit better.

Self-emptying docking station

There’s actually nothing special about the Auto-Empty docking station on the iRobot Roomba j7+. It does what it says it will do, and that’s about it. I haven’t had any problems with it for two months. Although I did notice that it has to go drain more often than the Roborock S7 MaxV did.

It still holds dirt and debris for about 6-8 weeks before needing a new dust bag. So pretty much the same as other self-emptying docks on the market.

The only downside here is that you can’t buy the dock after you buy the vacuum. Either you buy it when you buy your robot vacuum, or you suffer without it. This is where I think Roborock beat iRobot right now.

Which should I buy?

They are both very good robot vacuum cleaners, and I have had the pleasure of being able to use both models extensively. I would say the iRobot Roomba j7+ is better for those with more carpet in their home, and potentially a smaller house or apartment. While the Roborock S7 MaxV Plus is better for those with hardwood, laminate or tile floors, as it can also clean (and do a great job!). Both are also great for pet owners.

If you’re also someone who just wants to set it and forget it, then the iRobot Roomba j7+ is for you. There aren’t many settings available, which makes it ideal for your parents or grandparents.

Let’s not forget that both received an Editor’s Choice from us in our reviews of each model. So they are both very good robot vacuum cleaners.
