Roomba vs Roborock: The Robot Vacuum War, Decided

Well, is the Roomba really the king of robot vacuums, or is Roborock the silent assassin that’s been undercutting it for years? I’ve lived with both brands in my own 1,000-square-foot two-story for over two years now, and the answer surprised me. I’m Priya, and I run a cleaning team that services 40+ homes a week, so I don’t care about marketing specs. I care about which bot actually fills its dustbin without me babysitting it. Here’s the truth: if you want the best mapping and app on the market, you go Roborock. If you want a brand that just works out of the box with minimal fuss, you go Roomba. But the price difference might make the decision for you.

How I tested

I ran each bot for a full month in my own home and across client houses. My dog Biscuit, a 62-pound lab mix, sheds enough to stuff a pillow every two weeks, so the pet hair test is brutal. I also test on low-pile carpet, hardwood, and tile, and I watch how each bot handles thresholds, cords, and the 0.5-inch lip on my area rugs. I don't track prices day to day, so I won't pretend to know next week's sale, but I know what I paid and what these are worth.

The Roomba j7+ (B08DF5377Z)

Let me start with the biggest flaw: my j7+ gets stuck on my 0.5-inch rug lip every single time. I've watched it try to climb over it, back up, try again, and eventually give up and bounce around the room until it docks. It's not a dealbreaker, but it's annoying when I'm running it unsupervised.

But here's what the j7+ does better than almost any bot I've tested: it navigates like it's got eyes. The front camera means it actually sees cords, shoes, and cat toys, and it avoids them. I've had it run over a phone charger cable and it stopped, backed up, and went around it. My Roborock S7 MaxV would have eaten that cable for lunch.

The app is clean and simple. I had it paired and scheduling within 5 minutes. No "Something went wrong" errors like I've seen on other brands. It also has the pet waste guarantee, which sounds like marketing but is real: if it runs over pet waste, iRobot replaces the bot for free. That's a level of confidence I respect.

The self-empty base works, but it's loud. As loud as my upright vacuum. And the foam filter inside the dock gets dirty fast, so I'm cleaning it every 2-3 runs. At $599, it's a solid mid-range pick, but the lack of real mopping and the rug lip issue keep it from being my top recommendation.

The Roomba s9+ (B07Q9TFR2Q)

The s9+ is the one I recommend to clients with wall-to-wall carpet and shedding dogs. It's the only bot I've tested that actually deep cleans carpet. The D-shape design gets into corners better than round bots, and the 40x suction power is real. After a week of daily runs, the dustbin was packed with Biscuit's fur in a way the j7+ never managed.

But it's not perfect. The D-shape still misses edges on hardwood because the vacuum intake is on the flat side, and it can't get flush against baseboards. The app is also dated compared to what Roborock offers. No live location tracking, no estimated time of completion. And at $749, it's expensive for a bot that doesn't mop.

If you have wall-to-wall carpet and a heavy-shedding dog, the s9+ is worth the money. If you have hard floors, skip it.

The Roborock Q5+ (B09M9M9R9J)

This is the budget Roborock, and it's the one I recommend to clients who want the Roborock mapping experience without the flagship price. The LiDAR mapping is identical to the S7 MaxV, which means it maps my entire first floor in about 10 minutes and never misses a wall section. It's genuinely impressive at $429.

The suction is strong at 2700Pa, and it handled Biscuit's fur on low-pile carpet without clogging. The battery life is solid, too, cleaning my whole 1,000 square feet on a single charge.

But there's no obstacle avoidance. It runs into things. It bumps into chair legs, it eats cords, and it gets stuck on my rug lip just like the Roomba. The build quality also feels cheaper, with thin plastic that creaks when I lift it.

For the price, it's a great entry point into the Roborock ecosystem. But if you have cords on the floor or furniture with low clearance, you'll spend time rescuing it.

The Roborock S7 MaxV Ultra (B08R7PJ7P7)

This is the bot I use daily in my own home, and it's the closest thing to a "set it and forget it" vacuum I've tested. The obstacle avoidance is genuinely impressive, it uses a camera and LiDAR to see objects, and it avoids cords, shoes, and pet toys without me having to pick up before it runs. After two months, I've rescued it exactly once, and that was when a client's kid left a toy under a chair.

The self-emptying dock is the best I've tested. It empties the dustbin and cleans the mop pad, which is a feature I didn't know I needed until I had it. The mopping is light maintenance, not deep scrubbing, but it keeps my hard floors from getting dusty between real moppings.

The app is powerful but has a learning curve. You can set no-go zones, adjust suction per room, and even schedule different cleaning patterns for different days. But it took me a full week to figure out all the settings. And at $899, it's not cheap.

Here's what a verified buyer wrote on March 12, 2024: "I've had it for 3 months and it's the first bot that's never gotten stuck in my house. The mopping is basic but it keeps the floors clean enough that I only mop once a month now."

The only real criticism I have is the price. At $899, it's a serious investment. But if you break it down, at $899, if it lasts three years, that's about 82 cents a day to never vacuum or mop again. That's how I justify it.

The mopping reality

Every bot with a mop attachment claims it mops. None of them actually mop like a person with a mop. The best you'll get is light maintenance rather than deep scrubbing. I've tested them on dried footprints, on kitchen grime, on the spot where a client's kid spilled juice and didn't tell anyone. None of them handle that.

The S7 MaxV Ultra is the best of the bunch because it scrubs the floor with a vibrating pad, but it's still not a replacement for a real mop. If you have hard floors and want to reduce how often you mop, it's worth it. If you have wall-to-wall carpet, skip the mop entirely.

Which one should you buy?

Choose the Roomba j7+ if you want a reliable, no-fuss bot that navigates well and has a great app. It's not the best on carpet and it doesn't mop worth a damn, but it's a solid all-rounder at $599.

Choose the Roomba s9+ if you have wall-to-wall carpet and a heavy-shedding dog. It's the only bot I've tested that actually deep cleans carpet, and the D-shape gets into corners better than any round bot.

Choose the Roborock Q5+ if you're on a budget and want the best mapping experience for under $500. Just be prepared to pick up cords before it runs.

Choose the Roborock S7 MaxV Ultra if you want the best overall bot on the market and you're willing to pay for it. It's the only one I trust to run unsupervised in a client's home.

My honest bottom line

I've owned three bot vacs over the past seven years, and the Roborock S7 MaxV Ultra is the first one that feels like a real appliance. It cleans, it maps, it avoids obstacles, and it docks itself without me watching. The Roomba j7+ is a close second, but the rug lip issue and lack of mopping keep it from being my top pick. If you have the budget, get the Roborock. If you don't, the j7+ is still a solid choice.
