I have been testing robot vacuums for about a decade now. In that time, I have tried well over 100 different models. If you’ve read my Roomba s9+ review, you know that it has been one of my favorite robot vacuums since I first tried it. So when I heard that this flagship Roomba model’s successor was about to launch, I couldn’t wait to try the Roomba Combo j9+.
Now that I have spent several months with the Roomba Combo j9+ robot vacuum and mop, I can confirm that it’s a solid upgrade in many ways when compared to the s9+. And right now, it’s on sale with a huge $415 discount. This deal drops the Roomba Combo j9+ price to $984.46 from $1,399, marking a new all-time low for this model.
If you want to skip to the conclusion, the bottom line is that the Roomba Combo j9+ is the most impressive Roomba that iRobot has ever made. It takes almost everything I love about the Roomba s9+ and adds built-in mopping as well as even more intelligent features. Plus, it has a special auto-empty dock that refills the Combo j9+ with clean water each time it’s done mopping.
This model is from the Roomba Combo lineup, which is the designation that iRobot gives its robot mop and vacuum hybrid devices. In the past, iRobot users had to purchase a Roomba for vacuuming and a Braava for mopping.
If you’re curious, the “9” in this model’s name means it’s iRobot’s top-of-the-line Roomba. Then, the “+” means it comes with an auto-empty base station. As you can see in the images though, this auto-empty base station isn’t the same as the one that comes with other Roomba models.
The first thing you’ll notice is that the Roomba Combo j9+’s base station is much larger than other Roomba docks. There are a few reasons for that. This one has storage space inside for debris bags, which is a nice touch. But the dirty water and clean water tanks take up the bulk of the extra space inside.
Apart from the nifty new mopping features, the Roomba Combo j9+ has the strongest suction of any Roomba, ever. It’s even stronger than the s9+ that I love so much, but there is one downgrade that’s worth noting. The extra-wide rollers on the s9+ were terrific since they could pick up more dirt and pet hair in a single pass. Meanwhile, the Combo j9+ has regular rollers like the ones you would find on similar Roomba models.
The Roomba Combo j9+ holds up to 60 days of debris in the dock. It can also store enough water for up to 30 days of regular mopping. That means it’ll empty the dirty water and get refilled with clean water every time it mops. That way, you don’t have to worry about emptying it and refilling it yourself each time it runs.
That’s great, but it’s worth noting that this model doesn’t have the auto-wash and auto-dry feature that comparable premium robot vacuum and mop hybrids have these days. Check our Roborock S8 Pro Ultra review for an example of a model that cleans and dries its own mop pads.
In addition to everything else I’ve covered, the Roomba Combo j9+ has all the best features from every other high-end Roomba. Examples include smart obstacle avoidance, intelligent mopping that lifts the mop pads on carpets, and four-stage cleaning.
As you might expect, the biggest downside of the Roomba Combo j9+ is the sky-high price tag. At $1,399, this model is one of the most expensive robot vacuums on the market.
With Christmas right around the corner, however, iRobot is offering this model at the lowest price ever. Thanks to a $415 discount, the Roomba Combo j9+ is currently on sale for $984.46, setting a new all-time low that’s about $15 less than the previous low price from Black Friday last year.
Or, if you don’t need the mopping features, you can get the Roomba j9+ for $853, down from $899.
