Eureka vs iRobot Roomba: Which Brand Should You Buy?

Quick verdict

• Eureka, $399-1,199 list across five robots: laser navigation on every model, published suction on every model, and bagless self-empty on the two E20 machines. The cheaper-to-own brand.
• iRobot Roomba, roughly $200-1,100 across its lineups: the household name, the longest track record, and the P.O.O.P. guarantee on its j-series. Camera navigation, no published suction, bags everywhere it self-empties.

Prices are list prices as of September 2026; Roomba's are approximate street prices, because iRobot's pricing moves by retailer and by season. Eureka runs frequent promotions; noted where it matters. Everything here is based on specs and user reviews, not lab time. We make all five Eureka robots. None of the Roombas are ours.

The two lineups, side by side

Two observations before the argument. Our lineup is five robots, all laser-mapped, all with published suction, all with self-empty stations. Roomba's lineup spans more models, and the cheap half of it doesn't map at all; the expensive half maps with a camera, and every self-emptying base takes bags. That difference runs through everything below.

Where Roomba genuinely wins: trust, and one piece of paper

Roomba is the brand that made the category. iRobot shipped the first Roomba in 2002 and spent two decades turning the name into something your mother knows, and that is real value: parts and accessories are sold by every major retailer and a hundred third-party sellers, and when something breaks, you are never far from a fix. We can't match that footprint, and I won't pretend we can.

Then the P.O.O.P. Guarantee, which is the single strongest feature in this whole category. On its j-series, if the robot runs over pet waste, iRobot replaces the unit. In writing. Nobody else offers that, including us, and it matters more than any suction figure, because a robot that rolls through a fresh accident doesn't just miss it. It distributes it. If your dog has a sensitive stomach, the j7+ at about $599 is the insurance you're actually buying, and it's worth every dollar of the premium.

Credit where it's due beyond the paper. The j-series put pet-waste avoidance on the roadmap for the whole category, ours included: we build obstacle avoidance into the E20 Plus and the J15 line because iRobot proved owners would pay for it. That's the mark of the incumbent, and it's a real one.

The fair credit keeps going. iRobot has run customer support at scale for over twenty years, and it shows in a way ours doesn't. Our app is our known weak point, and our customer service track record, with refused warranty claims and lost paperwork reported by owners, is the part of our business I'd defend last. Anyone who tells you brand loyalty doesn't matter hasn't needed support on a Tuesday.

The trade-offs that come with the name are real too. Roomba maps with cameras on its j-series and s-series, and camera navigation is older technology than laser mapping: maps build more slowly, low light confuses it, and the cheap Roombas don't save maps at all. iRobot doesn't publish suction for its current self-emptying models, so the j7+ owner buys on trust. And every Roomba that self-empties uses a bagged Clean Base, roughly $60 a year.

Where Eureka wins: lasers, numbers, and a $0-a-year base

Every current Eureka robot maps with lasers. The E20 Evo Plus and the J15 line use LiDAR, and the E20 Plus uses a dual-line laser with a right-side PSD sensor. Laser mapping works in the dark, builds maps faster, and doesn't care how dim your hallway is. Every Eureka robot also publishes suction in pascals, and the numbers are on the page: 8,000, 10,000, 19,000, 22,000, 22,000. Roomba publishes none. When two brands differ on whether to show you the numbers, I know which one I'd trust with a carpet.

The E20 line is bagless. That's $0 a year against $60 for any Roomba with a Clean Base, and it changes the five-year bill in a way no other spec on this page does.

The J15 line is the place where I'll be hardest on us. We publish 19,000 and 22,000 Pa on those machines, and an independent carpet test measured our own J15 Evo Ultra well under its sticker, so treat the marketing number as a ceiling. Even as a ceiling, published beats nothing-at-all, which is what Roomba offers, and the FlexiRazor roller (J15 Ultra and J15 Max Ultra) that cuts hair off at 400 strokes a minute is a feature Roomba has no answer for at any price.

The five-year cost, stated plainly

The entry tier tells the same story. The E20 Evo Plus at $399 list matches the i3+ at about $399 upfront, and then the i3+ keeps billing: about $300 in bags over five years against $0. Same price to buy, $300 cheaper to own.

Nobody buys a robot planning for five years. That's exactly why the five-year number matters: the bag bill is the cost you never plan for, and it's the only one you can't see at the register.

Price tiers, honestly

At the bottom, Roomba wins on entry price. The cheapest Roomba lists around $200-300, and Eureka's cheapest robot lists at $399. That's where the sale matters: in past promotions the E20 Evo Plus has sold for $199 at checkout — a self-emptying LiDAR robot at the price of a random-bounce machine, when a promotion runs. With no promotion live, our floor is $399, and we're honest about that.

In the middle, the E20 Plus at $449 list sits under the j7+ at about $599, with more published suction and no bag bill. The j7+ answers with the guarantee, which I've already told you is the one feature in this category worth paying for on its own terms.

At the top, both brands charge flagship money. The J15 Max Ultra lists at $1,199; the s9+ launched around $1,100. Ours mops with hot water and cuts hair off its roller, with a pet video call on top. The s9+ is a pure vacuum with camera mapping. Different flagships, and the difference in what you get is not close.

What actually matters when you pick a brand

Navigation is the first thing to settle, because it's the difference between a robot that knows your house and one that guesses. Roomba's camera mapping works. It's older technology and it builds maps more slowly, and the cheap half of the lineup skips it entirely. Laser mapping is faster and works in the dark, and every Eureka robot uses it. If you have a dark hallway or a large house, that's not a tie.

The transparency test comes second. One brand publishes suction in pascals on every model. The other publishes none. You can decide which of those is easier to shop with, because I already know which one I'd rather compare.

Then the bin. Bagged or bagless is a $60-a-year decision that compounds into a $300 difference over five years, and it's the easiest spec on this page to verify: look at the dock, see whether it takes a bag. Roomba's all take bags. Our E20 line doesn't. The J15 line does, because the mop-washing dock needs a sealed system, and we tell you that because hiding it would be stupid.

What doesn't matter much: the sticker on the front and the age of the company. What matters is what the machine costs on year two, because that's when the bag bill has added up and the guarantee has either paid out or been forgotten.

Which brand should you buy?

• Your dog has a sensitive stomach: the Roomba j7+, about $599. The P.O.O.P. guarantee is the only written replacement promise in the category, and it's worth the money.
• You want the cheapest-to-own robot: Eureka. The E20 line is bagless, $0 a year, against $60 for every bagged base.
• You want published specs: Eureka. Every model publishes suction in pascals. iRobot publishes none.
• You want the name everyone recognizes: Roomba. That's worth something, and you should pay for it deliberately.
• You want the most machine per dollar: Eureka. The J15 Ultra at $699 list cuts hair off its roller and washes its own mop pad.

Roomba built this category, and the name still opens doors that ours doesn't. But the guarantee is paper, and paper is the only thing in this category that doesn't fail. If a robot and an accident have already cost you a floor, buy the paper. If they haven't, buy the math, and let the brand name be the tiebreaker it was always meant to be.
