We have another Roomba here with a model number where you won’t find much information on Google – the iRobot Roomba i8+. But don’t worry, you’ve come to the right place to find the information you need on one of the better robot vacuums out there.
The Roomba i8+ is the same robot vacuum as the Roomba i7+, except for a few extra accessories and a larger battery. Let’s go through the details of the standout features and to find the key differences between the Roomba i8+ vs i7+.
Are these differences enough to make the Roomba i8+ a good buy for the money?
If you’re in a hurry – Yes, the Roomba i8+ is one of the more expensive models, but worth the price. Don’t forget you’ll need a Costco membership. Otherwise, you may want to get the i7+ or even the Roomba s9+ on Amazon.
- CLEANS UP AFTER YOU, AND ITSELF - Forget about vacuuming for months at a time with the CLEAN BASE Automatic Dirt Disposal that allows the i7+ to empty itself for up to 60 days.
- POWERFUL PERFORMANCE & POWERFUL PICK-UP - Pulls in stubborn dirt & messes with a Premium 3-Stage Cleaning System & 10X the Power-Lifting Suction.

Unfortunately, you won’t find the i8+ on Amazon, online stores, or other sales channels like most robot vacuums. You’ll need to walk into a Costco store to find the Roomba i8+.
Let’s get into the details to see if the i8+ has the standout features that beat out traditional vacuums. I’ve spent 30+ hours testing and researching all there is to know about the Roomba i8+.
Roomba i8+ Features
As mentioned above, the Roomba i8+ and i7+ are
Size Dimensions and Weight
The Roomba i8+ size dimensions are 13.26 in. wide x 13.34 in. long x 3.63 in height. That allows it to fit under a variety of furniture like coffee tables. Getting stuck under furniture is always a concern, but the i8+ isn’t taller than other models, so you won’t need to buy new furniture if you’re replacing an older Roomba.
The i8+ weighs 7.28 lbs, the same as the i7+. It’s light enough to pick up and carry to a different room or floor of your home. Being able to pick up the Roomba anytime you want will help if you need to do a spot clean in an area.
Battery and Capacity
The Roomba i8 plus has a lithium-ion battery that’s 20% larger than the i7 plus. The i7+ will run for 75 minutes and that puts the i8+ at 90 minutes of run time.
The longer battery life is a nice advantage for the i8+ as it allows the i8+ to clean a little longer, before needing to go back to the Clean Base docking station to recharge.
In reality, the extra 15 minutes can make a difference for how fast your house is vacuumed. When battery life is low, they’ll recharge automatically with charge times around a couple of hours. If the robot vacuum can spend an extra 15 minutes before it needs to recharge, that means less trips to the charging dock, which means more more house is cleaned on each Roomba trip and less time overall.
For very high square footage homes, it makes a very big difference. Fewer trips from and back to the base station means more time vacuuming and less time traveling.
This is when the Recharge and Resume feature kicks in. When the i8+ finishes recharging at the charging station, it will resume cleaning from where it stopped. Huge plus and free of any battery life concerns.
Many other Roomba models have Recharge and Resume too, but unless they have a Plus+ next to their model number, you’re going to need to get your hands dirty, because you’ll need to manually empty the dustbin.
If you have a large house, that will quickly get annoying, so that’s why you’ll want to get a Plus Model. The i8+, i3+, i7+, and s9+ all self-empty.
The self-emptying models will give you hands-free, worry-free cleaning for up to 60 days, because you only need to empty the automatic dirt disposal bags when it’s full. In testing and reviews, that’s up to 30 cleaning cycles worth of debris that the Clean Base bags can hold.
Cleaning Technology System and Suction Power
The Roomba i8+ comes with iRobot’s Premium 3-Stage Cleaning system that offers efficient and optimized performance. Along with 10 times the suction power of the Roomba 600 models, it’s one of the most powerful robot vacuums deep clean homes.
The 10x Power-Lifting suction power and 3-stage system picks up the dirt, debris, and pet hair from all types of floor surfaces, from carpets to tiles to hardwood floors.
Ever have areas of your home that are dirtier than others? Any stubborn dirt? Don’t worry because the i8+ has the patented Dirt Detect Technology to find those locations.
The robot vacuum’s dirt detection sensor will see dirtier-than-normal spots on the floor and it will know to make extra passes over those locations to ensure the floors are clean.
Animal hairs and human hair aren’t a problem with the i8+ either. But if you do have a lot of hair on your floors, you should check the side wheels at least once a week for any tangled hair in the wheels.
Tangled hair can cause the wheels not to sufficiently rotate, which could break the wheels and potentially lead to overheating of the Roomba. I’ve seen a number of people ruin their wheels due to hair entanglements and need to buy new wheels.
Dual Brush Rollers and Edge Sweeping Brush
iRobot’s multi-surface rubber brushes are unique from other robot vacuum brands. Other brands and Roomba’s own 600 series models come with bristle brushes.
The patented brushes are made of rubber and lead to more effective cleaning, as well as less issues with hair entanglements. Bristles will get caught up with hair and you’ll need to spend more time manually pulling hair out of the bristle brushes.
Do you have different floor surfaces at home? The brush rollers on the Roomba i8+ will automatically adjust its height depending on the surface. The i8+ will vary its height for low/high pile carpet, rugs, hardwood, and other surfaces to clean the dirt, debris, and pet hair.
High-pile carpet and rugs are a tough space for any robot vacuum. The i8+ does a good job, but it doesn’t quite match up to the Roomba s9 and s9+, because the s9/s9+ have 40x suction power. That allows them to get a little deeper.
The i8+ has an Edge-Sweeping Brush to get the edges along the walls and the corners of a room. The Roomba’s well-known circular shape doesn’t allow the edge-sweeping brush to do an amazing job, but it’s still good. You may need to manually pick up of debris occasionally.
If you don’t want to pick up debris yourself in room corners, the D-shaped Roomba s9/s9+ will give you that. The D shape allows the s9 to get closer to the walls and corers to allow its edge brush to do its job. The Roomba s9+ is the top-of-the-line Roomba, so it’s not a surprise.
The Roomba i8+ is equipped with High-Efficiency filters that trap 99% of dirt, dust, dust mites, and allergens.
If you have pets, you’ll be glad to know that includes the pet allergens from your cats and dogs. For those with allergies, you’ll appreciate that.
The Costco model Roomba i8+ does come with 1 extra replacement filter, so there are 2 total replacement filters in the box.
The extra filters come in handy because it’s a good idea to change the filters every 2-3 months, depending on how often you run the Roomba. If you don’t change the filters, and they’re full of debris, the Roomba could also overheat because air isn’t cleanly flowing through the filters.
I do have a guide on how often to change Roomba filters to get an idea of what factors come into play before deciding to change filters.
Clean Base and Self-Empty
The Self Emptying feature and Clean Base station are what most people will want when they think home automation led by robot vacuums. People want a hands-off cleaning machine and that peace of mind.
The Plus+ Roomba models provide that to you, because they will empty their own dustbins when the dustbin is full. This is the feature that I love the most. The biggest benefit is that this gets as close to an automated home that cleans itself, without you doing much work.
The auto emptying dock will store up to 60 days of debris, dirt, and dust. When the dirt disposal bags are full, you’ll get a notification on the mobile app or the LED indicator on the dock will light up solid red.
For those with pets and kids, or if your home just gets dirty quickly due to the weather environment you’re in, you’ll love that you don’t need to get involved much at all.
You can schedule cleanings and the i8+ will go cleaning on its own, while you’re doing anything else. That’s what we want with our robot vacuums after all, autonomous cleaning.
If you have a large home, you’ll also be glad that the Roomba i8+ will clean until the battery is low, head back to the auto emptying dock by itself, empty its dustbin by itself, and then resume cleaning from where it stopped – all by itself.
Navigation and Mapping
The Roomba i8+ has iAdapt 3.0 Smart Navigation and Imprint Smart Mapping System. That provides a number of advantages for customized cleaning and more importantly, efficient cleaning with straight lines.
Smart navigation and mapping features give the i8+ camera sensors the ability to learn your home’s layout, smart maps for each floor, and adapt to your home’s layout for the best cleaning routes. You’ll often hear neat rows for efficient cleaning.
Lower budget models clean in random directions, meaning they’ll go in one direction until it hits something, then changes course. Random direction paths are present in the 600 series and e series.
The i8+ can store up to 10 floor plans, so if your house has multiple floors, you can carry the i8+ to different floors to let it clean by itself. Unfortunately, the i8+ doesn’t know how to climb up or down stairs…yet!
Creating and setting names for different areas and rooms of your home is easy. It’s also compatible with voice assistants like Amazon Alexa and Google Home/Assistant, so you can tell the i8+ to clean the cereal in the Kitchen.
The maps are stored in the Home App and you’ll easily be able to schedule spot cleanings as needed. I have two toddlers living at home with me, so these spot cleanings are a lifesaver. I can go on the iRobot App and tell my Roomba to clean my son’s bedroom.
You can also create Keep Out Zones in the app’s smart maps, they’re like virtual barriers, to prevent the Roomba from going into that specific area. These digital no go zones are one of the better interactive mapping features in the mobile app.
The i8+ does come with 1 Dual Mode Virtual Wall Barrier that the i7+ does not. Virtual barriers are physical devices you place on the ground. It creates invisible barriers in the form of a wall or a halo (semi-circle) around objects or sports. Another use case could be to place it in front of obstacles to avoid, like more fragile furniture.
With Imprint Smart Mapping and Link Technology, it allows the i8+ and Braava jet m6 robot mop to be in sync with what’s been vacuumed, so the Braava m6 can start wet mopping. That means more hands-off cleaning and mopping for you thanks to Imprint Link.

Final Thoughts – Roomba i8+ Review
The iRobot Roomba i8+ is a great robot vacuum option and will easily give you clean floors. The Costco package is a good deal with the extra accessories in the box that’s included:
- 2 Extra AllergenLock Disposal bags (4 total bags)
- 1 Extra High-Efficiency filter (2 total filters)
- 1 Dual mode virtual wall barrier
- 1 20% larger battery
The other comparable Roomba models to look at that might offer better pricing when on a deal are the i7+ and s9+. The s9+ is the top-of-the-line Roomba and definitely worth a look if you have a flexible budget due to its 40x suction power.

These are more expensive models, so if you’re looking for cheaper models that are still Wi-Fi connected, have smart features, and great on all types of surfaces like hardwood floors, look at the Roomba i3 and i3+. If you’re at Costco, look at the Roomba i4.
These all have the same power lifting suction technologies at a more budget friendly price point. If you’re looking for the auto emptying dock still, get the i3+.

Frequently Asked Questions FAQs
Roomba i7+ vs i8+ (Roomba i7 vs i8)
The Roomba i7+ and i8+ have the same features and the same Clean Base docking station. The i8+ Costco package does come with extra accessories and a larger battery, so the i8+ option does provide a better value. They’re both going to do a great job cleaning your house.
There are two situations where you may want to get the i7+. If you see the i7 plus at a cheaper price on Amazon than the i8+, you may want to consider buying the i7+. I’ve seen it cheaper occasionally on deal days. Or if you don’t have a Costco membership and don’t have anyone who could purchase it for you, the i7+ will give you the same cleaning performance.
Roomba i8+ vs s9+ (Roomba i8 vs s9)
The main differences between the Roomba i8+ and s9+ are their shapes and suction power. The i8+ has the iconic circular shape, while the s9+ brings the modern D-shape that offers better cleaning against walls and corners.
The i8+ and s9+ are higher end models, but they’re both standouts and well worth the money. You can’t go wrong with either, because they’re both worth their price points.
