- Floor Types - All current Roomba models adjust to clean various types of floors, including carpets, rugs, hardwood and laminate floors and similar. However, when cleaning carpets, best results are achieved on low- and medium-pile carpets, while thick, soft and high-pile carpets are not the best surfaces for Roombas.
- Multistage Cleaning - Roomba vacuums uses 3-stage cleaning system - they loosen, lift and suck the dirt and debris off the floor. Note that Roomba 890 and 960 deliver 5x more air-power than Roomba 600 and 700 series, while Roomba 980 deliver 10x more air-power than Roomba 600 and 700 series.
- Operating time depends on the model and varies from 60 to 120 minutes. Note that this is the time measured while cleaning flat, hard surfaces. When cleaning carpeted areas and when the unit has to traverse from flat to carpets and back, operating time is shorter. Fortunately, after the battery is almost discharged, all models return to the charging station for full recharge, but only Roomba 960 and 980 models resume their work after being fully recharged - thanks to their iAdapt 2.0 Navigation.
- Battery Type - All Roomba vacuums use lithium ion batteries. They provide plenty of energy, without increasing the weight of the vacuums. Good lithium ion batteries don't come cheap, but for high-end units like these, NiMH batteries simply can't deliver required energy and power, without adding more weight and volume.
- WiFi Connected - at the moment, all Roomba models are operated using the iRobot HOME App. The iRobot HOME App enables the user to remotely clean and monitor Roomba vacuum and to access support using smartphone. The Amazon Alexa and the Google Assistant are supported, too.
- Dirt Detect system uses sensors to detect concentrated areas of dirt, with the unit providing additional cleaning in those areas. Roomba 690 uses acoustic, while Roomba 890, 960 and 980 use acoustic and optical dirt sensors.
- Tangle-Free Rollers - Roomba 890, 960 and 980 use dual counter-rotating rollers which incorporate a rubber tread that grabs the dirt from any floor type while reducing hair tangles and brush maintenance. So, these are not 'tangle-free' rollers, but if you have issues with pet and human hair, go for at least Roomba 890 model. To improve cleaning of the corners and edges, Roomba vacuums come with the Side Brush, which pushed the dirt in the path of the main cleaning system.
- Air Filtration - Air filtration is good, even in Roomba 690 model, which doesn't use 'High Efficiency Air Filter' like Roomba 890, 960, and 980 models. Thanks to the 'High Efficiency Air Filter', Roomba 890, 960, and 980 vacuums captures 99% of allergens, pollen, and particles as small as 10 microns. Personally, this is still too far away from true HEPA air filtration (99.97% of particles down to 0.3 microns) - iRobot should consider improving air filtration in these new models. Remember that certain 'old' Roomba vacuums (for example - 770, 780, 790, 880) use/used true HEPA air filters. Some companies offer HEPA air filters for new Roomba vacuums - personally, I didn't test them (it should be done in the lab, after all), but if the whole vacuum as the unit is not designed as HEPA vacuum cleaner, adding HEPA filter will help, but it will not turn the unit into the true HEPA vacuum cleaner. On the other hand, HEPA air filters have higher pressure drop and require more motor power for the same air flow, especially when they get dirty. New Roomba vacuums, especially 890, 960 and 980 models have much stronger air power levels than older Rommba vacuums (600 and 700 series), leading to better vacuuming.
- Multi Room Cleaning - Roomba 690 and 890 come with iAdapt Navigation and it enables the cleaning of one singe room. Roomba 960 and 980 come iAdapt 2.0 Navigation system - this new navigation system enables multi room cleaning, 'recharge and resume', clean map reports and in the end, more efficient and faster cleaning. Older iAdapt Navigation system was simple and reliable, but in order for whole room to be cleaned, old Roomba vacuums required more time with many spots being cleaned several times.
- Custom Cleaning Preferences enables the user to set custom cleaning settings like number of passes, edge cleaning and similar. It is available on Roomba 960 and 980 models (again, thanks to the iAdapt 2.0 Navigation system).
- Deep Cleaning on Carpets enables the Roomba 980 model to clean more thoroughly on carpets, by increasing the cleaning power. Although this option draws more power from the onboard battery and decreases the area that can be cleaned with a single battery charge, Roomba 980 comes with 'recharge and resume' feature - if the battery is almost discharged before cleaning task is finished, robot vacuum will stop the cleaning task, recharge itself and continue its task where it stopped.
iRobot Roomba 690 Wi-Fi Connected Robot Vacuum Cleaner
iRobot Roomba 690 is robot vacuum cleaner based on the proven Roomba 650, very popular robot vacuum.
Roomba 690 includes:
- cleaning of all floor types, although it performs best on hard surfaces and low-pile carpets,
- cleaning system is patented 3-stage cleaning system (loosens, lifts and sucks in the dirt), with maximum runtime of 60 minutes on a single battery charge,
- when the battery is almost fully drained, Roomba 690 returns to the charging station, but since it comes with simpler iAdapt Navigation system, Roomba 690 doesn't resume the task after recharging,
- air filter is good, but not as good as in Roomba 890, 960 and 980 models,
- Roomba 690 is very light and compact robot vacuum cleaner, enabling the unit to clean under the furniture and beds, avoiding obstacles and object, especially if they can damage the unit (drop or cliff sensors),
- using acoustic sensors, it detects concentrations of the floor dirt and clean it more thoroughly,
- Roomba 690 is Wi-Fi enabled unit, enabling the user to control and monitor the unit using the iRobot HOME App.
For short, Roomba 690 is a great and affordable robot vacuum cleaner - it comes with many great features, but personally, don't expect it to be your only vacuum at home. IMHO, at least 2-in-1 cordless/corded stick vacuum cleaner should complement iRobot Roomba (and other robot vacuums, not just Roombas!) vacuums - people having larger homes should consider even some larger, full-size canister or upright (with extension hoses) vacuums to complement the Roomba and other robot vacuums.
iRobot Roomba 650 vs 690
These are two very similar models - Roomba 690 design is based on the Roomba 650. Main differences between these two models are:
- 690 model is Wi-Fi enabled unit,
- 650 model uses NiMH and 690 uses lithium ion battery,
- 650 is wider, lower and somewhat heavier - 650: 13.39 x 3.6 inches, 7.9 lbs; 690: 13 x 3.7 inches, 7.8 lbs,
- 690 is Amazon Alexa and Google Home compatible, while 650 is not.
Which one to pick, 650 or 690? Obviuosly, 690 model comes with several new, very important features, making it IMHO better choice. On the other hand, since 650 is being slowly phased out, it can be found new, on sale, for cheap.
iRobot Roomba 890 Wi-Fi Connected Robot Vacuum Cleaner
iRobot Roomba 890 sits between Roomba 690 and Roomba 960. Like Roomba 690 it uses iAdapt Navigation system - it is controlled and monitored via iRobot HOME App, delivers up to 60 minutes of operation on single battery charge and can return to the charging station when the battery is almost drained. Like 690 model, 890 model can't resume cleaning task after automatic recharging.
Also, 890 can detect areas with larger amount of dirt, but it uses both acoustic and optical sensors for detection. Air filtration is improved by using high-efficiency air filter, which is not HEPA grade air filter. Rollers are of novel design to prevent, or at least, reduce hair tangles and brush maintenance.
3-stage cleaning system is combined with 5x more air power suction (compared with 600 and 700 series), delivering 50% better cleaning.
iRobot Roomba 780 vs 890
iRobot Roomba 780 is not available via official iRobot site, but it can be found at local and online stores.
Roomba 780 doesn't come with Wi-Fi connectivity, and it can't be integrated with Amazon Alexa or Google Assistant. It is controlled via remote control and delivers features which I personally miss on new Roombas, especially 690 and 890 models:
- iAdapt Multi-Room Navigation enables Roomba 780 to clean several rooms at once,
- true HEPA air filtration!
Most of other features are practically the same or very similar - cliff sensors, obstacle sensors, cleaning schedule, etc. On the other hand, Roomba 890 has stronger air power and due to improved rollers, better cleaning capabilities.
For short, if you have pets or issues with asthma and allergies and you can buy new Roomba 780, don't give up on it right away, just because it is an 'older model'.
iRobot Roomba 880 vs 890
Roomba 880 is older model of robot vacuum cleaner that share many similarities with 890 model. Also, there are few, very important differences.
Roomba 880 iAdapt Multi-Room Navigation system in combination with full suite of sensors, enables it to clean up to 3 rooms with the included Virtual Wall Lighthouse beacons.
Both 880 and 890 models include: Self-Charging, Scheduling, Tangle-Free Debris Extractors (IMHO, 'almost-free'), AeroForce 3-Stage Cleaning System with 5x the air power found on 600 and 700 series vacuums.
Roomba 890 is Wi-Fi enabled unit and that means: the iRobot HOME App, option for integration with Amazon Alexa and Google Assistance.
Note: some sites claim that Roomba 880 comes with HEPA filter, but both models (880 and 890) use the same AeroForce High-Efficiency Filters - they provide good air filtration, but they are not HEPA air filters.

iRobot Roomba 960 Wi-Fi Connecetd Robot Vacuum Cleaner
Roomba 960 is Wi-Fi connected robot vacuum cleaner. Thanks to the iRobot HOME App, it can be controlled and monitored using a smartphone - not required, but recommended.
This model uses improved iAdapt 2.0 Navigation system, which enables the multi-room cleaning, recharge and resume operation, clean map reports, custom cleaning options etc.
It has somewhat better maximum operating time than 890 and 650 models (75 vs 60 minutes), but shorter when compared with Roomba 980 model (75 vs 120 minutes).
Rooomba 960 also uses AeroForce High-Efficiency Filter for air filtration, which provides acceptably good air filtration.
Tangle-free brushes handle pet and human hair relatively ease, requiring less manual maintenance.
iRobot Roomba 960 has many of the features of more expensive 980 model, except:
- shorter operating time (75 vs 120 minutes),
- same patented 3-stade cleaning system, but half of the air power (5x vs 10x, compared with 600 and 700 units),
- both units adjust their cleaning heads, depending on the surface type, but 980 also additionally increases cleaning power on carpets.
All in all, Roomba 960 is excellent robot vacuum cleaner and it gets its job done. Unless you really need features found only on Roomba 980, Roomba 960 is highly recommended.

iRobot Roomba 980 Wi-Fi Connected Robot Vacuum Cleaner
At the moment, Roomba 980 is top Roomba model, offering great and rather interesting features, but it also comes with respectable price tag.
Like other Roomba models, it is suitable for cleaning all floor types, with the best cleaning on the hard floors, laminate, tiles, low- to medium-pile carpets etc. High pile carpets and deep, thick rugs can prevent the unit from traversing such floors.
It is Wi-Fi connected unit and the use of the iRobot HOME App is highly recommended with this model - in combination with advanced navigation system, dirt detect, cliff and other sensors, recharge and resume system, unit can clean entire level of the home or apartment (up to 120 minutes of operation n the single charge).
Roomba 980 has the strongest air power available - it is adjustable, with the maximum air power of 10x air power found on 600 and 700 series. Such cleaning power let the unit to deeply clean even the thicker carpets and rugs.
Roomba 980 uses the same High-Efficiency Filter (just like Roomba 890 and 960), having good air filtration, but not HEPA air filtration.
Note: HEPA filtration requires more power due to larger pressure drop on such filters and this would require larger and heavier batteries for the same cleaning power or drop in available cleaning/air power.
For short - Roomba 980 is great robot vacuum cleaner, but not with the most affordable price :)
