The "Roomba" robotic vacuums, supplied by iRobot are available in 5 different models. Which one to choose? This page shows you clearly the differences and how you can find the perfect model for you.
The chart below lists more than a dozen features for each of the 5 models, currently available.
For more information on what each feature title means, just click on the title and you will be given a full description.
To see more details of each model, just click on the photo at the top of the chart
As you can see all 5 models are "self charging" This is because all models feature a "Home" station. Here the robotic vacuum parks and is automatically recharged.
Just make sure the Home Station is plugged into a power outlet!
Once the Roomba is in the charge mode, it will stay until charging is complete. It will start a new cycle if scheduled to do so or if manually started.
Note that the clean cycle time must be less than the run time or vacuuming will be incomplete.
The two 900 series models incorporate this feature. When the robot returns to Home for a re-charge, it "remembers" where it was in the cleaning cycle and upon completion, returns to the spot where it was and resumes cleaning.
Note that The 900 series have the longer run times and can clean larger areas.
Just the 880,960 and 980 have this ability.
The model 880 is unique in coming complete with two infra-red light equipped "Light Houses". These can be placed at doorways and then the robotic vacuum cleaner will stay in the first room until the cleaning cycle is complete and then enter the next room.
This is a more efficient way to clean than trying to finish two rooms and continually moving from room to room.
You can select to keep the vacuum permanently out of a room, if desired
The 960 and 980 do not use Light Houses but do have a longer run time and the navigation system comes with "Visual Localization". This enables the robot to see obstacles and compensate it's path.
The 980, with it's long run time of 2 hours, can clean up to 2,000 sq.ft. on a single level.
The 900 series have "Visual Localization" and vSlam® technology to create visual landmarks so it does not loose track of where it is or where it has been
This video is well worth a look because it shows so much. The 980 model is seen in action and a map is displayed, showing the path that the robot takes in cleaning an entire level.
Please note that the robot does NOT move at anything like the speed shown and will takes a few hours to clean an area of this size!
This is approximately how long the robotic vacuum will run after charging at the Home Station.
The times are for comparison purposes only! Run times can be affected by many factors, such as floor type, battery condition and how dirty the floor is!
This is another approximate time that can vary depending on battery condition and is shown for comparison purposes only.
Rechargeable batteries have a life span largely determined by the number of charge/recharge cycles it has been subjected to. When the run time and/or recharge time start to change then the time to replace the batteries may be approaching.
It is a bit like setting a digital alarm clock! You can program any time of the day to start and set up to 7 times per week.
The short video below shows how it works-
All models except the 650 use these rubber rollers. Good for all floor types and they reduce hair tangles.
The model 650 uses brushes that can be a problem to keep hair tangles to a minimum. (Especially if you have pets)
Just the 960 and 980 models have this feature. You can connect from your smart phone and check the status of the robotic vacuum. You can select custom cleaning preferences and change schedules. Very convenient!
This feature is only available on the 900 series models.
The 3 stages are-
On the 860,880 and 960 models there is 5 times the power of previous models and on the 980 you will experience 10 times the power.
The 650 has brush rollers instead of the extractors. Hair can more easily tangle. and can be a challenge to remove.
Only available on the 980 robotic vacuum: When a carpet is sensed, the vacuum motor is boosted to 10 times the power, to really dig deep and suck up the maximum amount of debris!
Optical and acoustic sensors detect high concentrations of dirt ,debris,dust and pet hair and the robot will do several passes over the area, ensuring it is as clean as possible.
A spinning side brush sweeps dust and dirt from wall edges and corners into the path of the 3-stage cleaning system.
High efficiency Heppa filters capture 99% of allergens, pollen and small particles down to 10 microns in size
Stairs are no problem for any Roomba model, Sensors "see"the edge of stairs and the vacuum reverses before it can tumble down.
A disadvantage with the sensors occurs if you have carpets with black strips in the pattern. Roomba assumes these are stairs and will not clean them!
I have heard of some customers taping over the sensors, so as to allow cleaning of the black stripes.
This unit can block off a doorway and prevent Roomba from leaving a room.
It should be placed on the outside of the doorway and the arrow, on top of the unit, should be pointed across the opening.
There are 2 modes that can be selected by a switch: When "Auto"is selected then the unit will be activated when the Roomba starts a cleaning cycle.. It will be switched off after 135 minutes.
2 alkaline "C cells are needed to power the virtual wall and they should last about 6 months.
This unit can be used as a"virtual wall" and keep the Roomba in the rooms that need to be cleaned.
If set to "halo" mode then a 4 ft. (1.2M) diameter keep-out zone is created, that can keep the robot away from pet dishes or Christmas trees etc.
Unit is powered with 2 AA cells and a set is included with the original purchase
This unit can be used for multi-room cleaning. It should be set up as shown in the diagram and then Roomba will clean each room completely and then be allowed to move to the next room.
It can also be used as a virtual wall and protect areas from the robot vacuum.
The lower switch turns the unit on and off. When "on" it is in a low current standby mode and is switched fully on when Roomba approaches.
The upper switch is to change from lighthouse mode to virtual wall mode.
It does require (2) "c" cells for power.
