Differences
1. Voice Control
The iRobot Roomba 890 has the advantage of voice control since it uses Wi-Fi. Because of the Wi-Fi technology used, it works with Amazon Alexa and Google Assistant. With few commands to your Amazon Alexa or Google Assistant, you can get your Robot to start cleaning. Unfortunately, the iRobot Roomba 877 does not have any feature of voice control.
2. Wall Barriers
Though most of the differences favor Roomba 890, when it comes to wall barriers, we do think Roomba 877 has got a win. Roomba’s best feature is the ability of the vacuum cleaner to prevent itself from going to a room that is restricted. It is done by mapping the entire house and decides the rooms to clean. But if you wish to block the vacuum from a particular place, the concept of wall barriers come in the picture. Wall barriers are present in two different forms in the two models.
The iRobot Roomba 877 uses a technology called the Virtual Wall Lighthouse. These can be placed in front of near the entrance of the room you want the Robot to prevent. But, after the cleaning is complete, it is capable of entering the next room. This feature of the Roomba 877 is handy if you want to make sure that the area is thoroughly cleaned before it moves to the next place.
On the other hand, the iRobot Roomba 890 has the simple Virtual Wall Barriers. These help in preventing the vacuum from entering a specific room. The only difference is, it cannot let the Roomba inside once the cleaning is complete. So, we can say that 877 has more options than 890. Although the Virtual Wall Barriers are easier to understand, we are not sure why they removed the feature in the updated version.
3. Remote Control
The first difference is the use of remote control in the Roomba 877. Since the Roomba 877 does not support Wi-Fi, there should be another way to control it, that is through Remote Control. With the help of the remote, you can start the vacuum and schedule a cleaning program as well. If you want any area or spot to be cleaned a little more extra, you also have the option of selecting the spot clean.
But one downside with the remote control is, you need to be in the range of 15 feet of your vacuums for your commands to work. But, the Roomba 890 works on Wi-Fi technology and takes full advantage of it. You can connect the vacuum to the Wi-Fi with a single tap on your iHome App.
The App is supported in both leading platforms like Android and iOS. The advantage of Wi-Fi over remote control is that you do not to be in a precisely defined range for your vacuum to function. It can work even if you are miles away only if you are connected to your Wi-Fi. So, with this feature, also, when you are on vacation or elsewhere on work, you can make sure your home is dust-free.
You can schedule a cleaning before you go to work, and once you reach home, your house will be neat and tidy. So, in the case of connectivity and flexibility, we do think the Roomba 890 has all the advantages with the Wi-Fi. However, if you feel you don’t need the Robot to clean when you are away, then you can select the Roomba 877.
4. Battery Life
When we talk about batteries, the Roomba 890 is better than the iRobot Roomba 877. In the 890, you have a longer runtime on a single charge. This is due to the different type of battery technology that is used in these robots. The 877 uses a Nickel Metal Hydride battery that can run up to 65 minutes. This runtime is better for medium-sized houses. But if you have a larger home, you will notice the Roomba moving to its station to charge even before the cleaning is complete.
On the other hand, Roomba 890, has a Li-ion battery. Hence it has a total runtime of 120 minutes on a single charge. It makes sure the cleaning is complete before it goes to the charging station. The Lithium-ion battery is also capable of charging quickly. So, in the case of battery life and run time, the Roomba 890 is better than the 877.
Similarities
1. Anti-Tangle Technology
The vacuum is smart enough to do the job by itself. But can you leave the Robot to do the work without being watched? Most of the rooms are filled with many obstacles like toys, clothes, cords, and what on. The vacuum can clash with it and might not complete its job. But with the iRobot Roomba 890 and iRobot Roomba 877, it has the anti-tangle technology. It makes sure that the vacuum does not get stuck on cords and carpet. But even with this technology, do make sure you have an open path for your vacuum to travel. However, if you have missed any area, the Anti-tangle technology is there to save you.
2. AeroForce High-Efficiency Filters
Vacuuming removes all the dirt from the floor. But all the dust collected can knock off into the air. The vacuums have AeroForce High-Efficiency filters. The filters do an excellent job of catching the dust and dirt. But we do hope that they try to implement the HEPA filters that are capable of capturing dust as small as 0.3 microns. Although these filters are suitable for dust and dirt, it is not capable of capturing small particles like pollen. So, we do think that using a HEPA filter in these vacuums will make it better.
3. iAdapt
Both the Roomba 877 and iRobot Roomba 890 have iAdapt technology in them. The vacuum consists of two sensors that are used to map the whole house before it starts to clean. This technology is present in the newer models of Roomba. Hence, using this advanced technology, we do not have to worry about the robot vacuum moving to restricted rooms.
The robot vacuum will understand the areas which require extra attention. So, do not have to worry about the bread crumbs that have fallen, because the vacuum will make sure that it has got a hold of it. The suction power of the vacuum depends on the floor it is cleaning. When it comes to carpets, the suction power of the vacuum increases to increase the strength of capturing dust.
4. 3- Stage Cleaning
The cleaning process used in Roomba is what made Roomba famous among the others. The Roomba 877 and 890 use the 3-stage cleaning process. In the first process, the rotating brushes will lift all the dirt from your floors. Next, it will brush along the walls to remove any particle that has been hanging. The final step is where the suction comes to the picture. Using the powerful suction, it will remove everything from the brushes and transfer it into the dustbin. With this 3-stage cleaning process, you are sure to have a dust-free home.
5. Set Schedules
Both the iRobot Roomba 877 and the 890 has the feature of scheduling the cleaning. That means with the use of Wi-Fi or remote control, you can set the timing and the date of your cleaning. It can be kept at a regular interval up to seven times a week. With this feature, you do not have to worry about cleaning your home. Because your robot vacuum does the job for you, all you have to do is a schedule and wait for the magic to happen.
6. Avoids Stairs
Since both the vacuum cleaners are a bit expensive, you do have to make sure that you do not damage it. While cleaning, you don’t want your vacuum to fall. Because of this, both the vacuums have a cliff-detect sensor that will detect heights and prevent it from falling off stairs.
