You're standing in the middle of your living room, staring at a tumbleweed of dog hair and wondering if it's finally time to outsource the labor. It’s a classic dilemma. Everyone knows the brand name, but when you actually sit down to figure out how much is a roomba, the answer isn't a single price tag—it’s a confusing maze of model numbers, "s" series, "j" series, and "Combo" designations that make your head spin.
Buying a robot vacuum used to be simple because there were only two options: the one that worked and the one that bumped into walls until it died. Today? iRobot has a lineup that ranges from a couple hundred bucks to well over a thousand. Honestly, the price you pay depends entirely on whether you just want the crumbs gone or if you need a machine that can literally identify and dodge a "gift" left behind by an untrained puppy.
Let’s get into the weeds.
The Entry Level: Budget-Friendly Roombas
If you just want the basics, you’re looking at the 600 series. This is the "old reliable" category. These models usually retail between $179 and $250, depending on the season. You’ve probably seen the Roomba 694 on Amazon; it’s a perennial bestseller because it’s cheap and it works.
But there's a catch.
These lower-priced models use "bump and run" navigation. They don't map your house. They just wander around like a confused toddler until they hit a chair leg, then they turn and try again. It’s chaotic. It’s loud. But for a small apartment with hardwood floors, it gets the job done without draining your savings account. If you have a massive, sprawling floor plan, though, a 600 series will likely get lost and run out of battery in the middle of the hallway.
Stepping Up: The Mid-Range Sweet Spot
Most people end up in the $350 to $600 range. This is where you find the Roomba i3+ (now often called the Roomba Combo i5 or similar variants) and the Roomba j5.

What are you paying for here? Mapping.
A Roomba that maps your house is a game-changer. Instead of bouncing around randomly, these machines move in neat, efficient rows. They know where they’ve been and where they need to go. More importantly, this price tier often introduces the "Clean Base"—that's the tower that sucks the dirt out of the robot so you don't have to empty it every single day.
I’ve talked to dozens of users who say the self-emptying bin is the only reason they actually use the vacuum. Without it, the robot fills up in ten minutes, stops, and waits for you to save it. If you’re asking how much is a roomba with a self-emptying bin, expect to pay at least $400, though sales can occasionally dip that number lower.
The High-End: Obstacles and AI
Then we have the heavy hitters. The Roomba j7, j9, and their "Combo" (mop) counterparts. These start at $600 and can easily climb to $1,000 or $1,200 for the flagship Roomba Combo j9+ with a Refill & Rebuild dock.
Why on earth would a vacuum cost as much as a used car?
Intelligence.

The j-series features a front-facing camera. iRobot famously put out the "P.O.O.P. (Pet Owner Official Promise)" guarantee with these. The AI is trained to recognize solid pet waste and steer clear of it. If you’ve ever seen what happens when a standard robot vacuum meets a pile of dog mess, you know that $800 is a small price to pay to avoid the "poopocalypse."
These high-end models also handle carpet better. They have higher suction power and can detect which rooms get the most foot traffic, prioritizing those areas for deeper cleaning. The j9+ specifically has a "Quiet Drive" mode that shuts off the vacuum motor while it’s traveling to a specific room, which is a nice touch if you’re working from home.
Breaking Down the Current Market Pricing
- Roomba 694/Essential: $179 - $249. Simple, effective, no frills.
- Roomba i3+ / i5+: $399 - $549. Adds smart mapping and self-emptying.
- Roomba j7+: $599 - $799. Adds AI camera for obstacle avoidance (cords, shoes, pet waste).
- Roomba j9+ / Combo j9+: $899 - $1,399. Top-tier suction, automatic mop-water refilling, and premium finishes.
Hidden Costs Nobody Mentions
The sticker price isn't the final price. This is where most people get caught off guard. Roombas have "consumables."
You have to buy bags for the self-emptying base. You have to replace the HEPA filters. The spinning side brushes eventually fray and snap. The green rubber extractors (the rollers) wear down after six to twelve months of grinding against your floors.
On average, you should budget about $50 to $100 per year for maintenance kits. If you buy the mopping versions, you also have to buy the specific cleaning solution, as iRobot warns that third-party cleaners can corrode the internal pumps. It’s a classic printer-and-ink business model. Keep that in mind when you're calculating how much is a roomba for your long-term budget.
Why Does Roomba Cost More Than Competitors?
You’ll see brands like Shark, Roborock, or Eufy offering similar specs for $100 or $200 less. It’s tempting.

But iRobot’s real value isn't just the hardware; it's the software and the repairability. You can buy a replacement battery, a new wheel module, or a whole new cleaning head for a Roomba on their website or even on Amazon. Most "cheap" robot vacuums are disposable—if a motor dies, the whole thing goes to the landfill.
Also, the app experience matters. iRobot’s app is generally considered the gold standard for ease of use. Setting up "Keep Out Zones" or scheduling a clean for "under the dining table" after dinner is seamless.
Is It Worth It?
Honestly? It depends on your floor type.
If you have 100% thick, plush carpet, even the most expensive Roomba won't replace your upright Dyson or Miele. Robot vacuums are "maintenance" cleaners. They keep the surface clean so you only have to do a deep manual vacuum once every two weeks instead of every two days.
However, if you have hardwood, tile, or laminate, a mid-range Roomba is life-changing. It’s the difference between feeling grit under your feet at 5:00 PM and having a pristine floor.
Strategic Buying Tips
Don't buy a Roomba in June or July unless you absolutely have to.
iRobot follows a very predictable sales cycle. The best prices are always during Prime Day (July and October) and the Black Friday/Cyber Monday window. You can often find the $800 models for $500 during these windows.
Another pro tip: check the "Renewed" section on Amazon or the "Certified Refurbished" store on eBay. These are often units that were returned within 30 days, cleaned, tested, and sold with a warranty for 30-40% off the MSRP.
Actionable Next Steps for Buyers
- Measure your clearance: Check the height of your couch and bed. Most Roombas are about 3.6 inches tall. If your furniture is lower than that, the robot can't clean there.
- Evaluate your "clutter" level: If you have kids with Legos everywhere or a dog that leaves toys out, you must get a j-series with a camera. A 600 or i-series will just eat the toys and get stuck.
- Check your Wi-Fi: Roombas require a 2.4GHz signal for initial setup. If your router is strictly 5GHz and you aren't tech-savvy enough to split the bands, you might struggle with the setup.
- Start with the i5+: If you're unsure, the Roomba i5+ is currently the best "bang for your buck" for most households. It maps, it self-empties, and it doesn't cost a mortgage payment.
