iRobot Roomba 104 Review: Smart Mapping on a Budget

The iRobot Roomba 104 brings LiDAR mapping, room zoning, and strong suction to a budget robot vacuum, ideal for small homes and pet owners.

Pros

Cons

If you’ve been holding off on a robot vacuum because “real” mapping bots seemed too expensive, the iRobot Roomba 104 is the first one we’ve tested that genuinely feels like a modern, LiDAR‑guided Roomba at a budget price.

It’s not perfect, and it doesn’t magically replace a deep-clean upright. But for around $125, it delivers structured, room‑by‑room cleaning, proper obstacle handling, and app control that used to live on models two or three price tiers up.

A LiDAR Roomba That Actually Knows Your Floorplan

Most budget robot vacuums still wander like a tipsy Roomba 600-series: bump, turn, guess, repeat. The 104 doesn’t. It uses a LiDAR turret to scan your rooms, then drives in straight, overlapping rows the way a human would mow a lawn.

In our lab’s 900 sq ft test apartment (mix of hardwood, low‑pile carpet, and tile), the Roomba 104 produced a map on its first full run in about 37 minutes. On subsequent runs, it consistently cleaned the same space in 31–35 minutes, with coverage heatmaps showing no obvious blind spots.

I deliberately left a folding chair at an odd angle, a laundry basket halfway into a doorway, and some kids’ blocks scattered along a wall. The 104 slowed, skirted, and re‑routed around them instead of repeatedly ramming or getting hung up. It’s not “object recognition” in the j7 sense—there’s no AI camera—but the LiDAR plus bump sensors combine into a very competent navigator.

Our home safety tester also ran it near a split-level staircase. The cliff sensors did their job: repeated passes right up to the edge, no hesitation to approach, and no near‑falls.

If you’ve dealt with older random‑pattern Roombas, the difference is immediately obvious. Rooms feel fully covered, and the vacuum doesn’t spend the last 10 minutes wandering in circles in the hallway trying to find its dock.

Suction and Pickup: 70x Sounds Wild, But Here’s What It Means

iRobot claims “70x more power‑lifting suction vs 600 series,” which sounds like a marketing fever dream. We treated it as such and went to the bench.

Our vacuum tester compared the Roomba 104 against a Roomba 694 (basic 600‑series) and a Eufy RoboVac G30:

- Roomba 104: 96% average pickup - Roomba 694: 86% - Eufy G30: 93%

- Roomba 104: 90% - Roomba 694: 76% - Eufy G30: 84%

So no, it’s not literally 70 times stronger in real‑world results—but it is clearly in a different league from the 600 series, especially on carpet and fine debris.

Where the 104 really impressed me was fine dust on medium‑tone hardwood. After a full pass, barefoot walk tests (our unscientific but telling method) turned up almost no grit. In a house with a dog and a toddler, that’s saying something.

Pet hair is a bit more nuanced. The multi‑surface brush rolls do a good job of pulling hair off carpet and rugs, but long hair will wrap around the roller over time. In our two‑week pet hair stress test, we had to clear the brush about every 5–6 runs in a two‑dog household. That’s normal at this price, but if you’re used to the newer anti‑tangle dual rollers on higher‑end Roombas, this feels like a step back.

Noise levels hit 63–65 dB on standard suction, and about 67–69 dB on max, measured one meter away—noticeable but tolerable. You probably won’t run it during Zoom calls, but it’s quieter than most upright vacuums and in line with other robots in this class.

Everyday Use: Schedules, Zones, and Spot Cleaning

Living with a robot vacuum is less about raw suction and more about whether you can make it behave. On that front, the Roomba 104 feels more expensive than it is.

Using the iRobot Home app, we were able to:

Our smart home editor appreciated that keep‑out zones respected their boundaries every time across 20+ runs; some cheaper competitors drift in and out of virtual walls as their mapping gets fuzzy.

Spot cleaning deserves a callout. When you trigger it (either from the app or by button), the 104 repeatedly spirals around a focused area for up to about 5 minutes. We used this after kids’ snack time under the dining table and after potting plants on the kitchen floor. It didn’t catch every crumb in a single cycle, but it gathered the visible mess into the bin rather than smearing it around.

Battery life in our testing ranged from 75 to 95 minutes depending on suction level and floor type. In a 1,200 sq ft main level, that was enough for full coverage on standard power in a single run. If your space is larger or you run max suction on mostly carpet, expect the robot to do a mid‑clean recharge and then resume.

The self‑charging behavior was reliable in the lab and in a real home. Even when we manually picked it up and dropped it in another room, the 104 paused, realigned with its map, then navigated back to the dock without wandering for 10 minutes first.

App, Voice Control, and Smart Home Behavior

For this price, the software experience is arguably the Roomba 104’s biggest advantage over off‑brand robots.

We used the iRobot Home app on both iOS and Android. Setup took about 10 minutes: connect to Wi‑Fi, run an initial mapping cycle, name rooms, done. The interface is clean and responsive, and even our less tech‑savvy tester had no trouble scheduling runs by room.

Voice control worked as advertised with Alexa and Google Assistant:

There’s no deep automation logic baked in (this isn’t a premium “learn your habits” model), but for basic voice commands and app scheduling, it’s frictionless.

We also appreciated the maintenance reminders. After about a week of daily runs, the app nudged us to check the filter. It’s a small touch that keeps performance consistent, especially in dusty or pet‑heavy homes.

Build, Bin, and the Realities of a Non-Plus Roomba

Physically, the Roomba 104 feels like a midrange iRobot: solid chassis, clean hinge tolerances, and buttons that don’t feel mushy. The LiDAR turret does add some height—our calipers measured 3.7 inches total—which means it won’t fit under the very lowest sofas or TV stands.

The dustbin is where the “budget” side shows more clearly. It’s a standard lift‑out bin with a basic latch and filter. In our mixed‑floor test home with one shedding dog, the bin filled up every 1.5–2 full runs. Without an auto‑empty dock, you will be emptying this regularly.

This is the main differentiator versus iRobot’s “+” models (like the Roomba i3+ or j7+). Those can run for weeks with minimal interaction; the 104 requires you to stay involved. If you’re hoping for a nearly hands‑off experience, this isn’t it.

Still, at this price, we think the trade‑off is fair. You’re getting proper LiDAR mapping and smart zoning rather than a fancy dock and a dumb robot.

Durability is harder to judge long‑term, but after 50+ cycles in our lab plus two weeks in a real household, we saw only light scuffing on the bumper, no degradation in wheel traction, and no error codes beyond a single “brush jam” caused by a sock (which we’d expect on any robot).

How It Stacks Up Against Other Budget Bots

We spent time bouncing the Roomba 104 against two common alternatives:

\*Street prices fluctuate, but this reflects what we saw during testing.

Against the Eufy G30, the Roomba 104 wins on mapping, zoning, and app polish. The G30 is slightly shorter and can squeeze under more furniture, but its navigation is less precise, and you don’t get room‑based cleaning.

Compared to iRobot’s own 600‑series, the 104 is superior in almost every functional way: navigation, pickup, app features, and mapping. The only reason to pick a 600‑series at this point is if you find it significantly cheaper and don’t care about smart mapping at all.

If we step up in price bracket, the Roomba i3+ or j7+ with a self‑emptying dock are still better choices for people who travel a lot or absolutely hate maintenance. But those typically cost 2–3x as much. For budget‑conscious buyers, the 104 hits a sweet spot: modern brains, solid cleaning, manual bin.

Who Will Be Happy With the Roomba 104—and Who Won’t

In our view, the Roomba 104 makes the most sense if:

Pet owners with mostly hard floors will be particularly well‑served—pickup is strong, and the edge brush does a good job around baseboards where fur tends to accumulate.

You should probably skip the 104 if:

Within those expectations, though, the Roomba 104 is one of the most compelling budget robot vacuums we’ve tested this year: not because it’s the absolute strongest suction monster, but because it finally brings iRobot’s better navigation and app experience down into a genuinely affordable price band.
