There Are Differences Between the Roomba I8+ and the I7+.

The main distinction in the performance of the i8+ and the i7+ is their runtime. The i8+ can run for up to 90 minutes before recharge, while the i7+ lasts up to 75 mins. The other distinction is the accessories included. 

The Roomba i8+ comes with a virtual wall barrier, four disposal bags, and two filters. Roomba i7+ does not have a virtual wall accessory but includes five disposal bags and a filter.

That’s the shorter version. For the more extended version, let’s look at the time to examine the differences in depth.

One Difference Is That the Roomba I8+ Has a Larger Battery Capacity That Can Run For 90 Minutes, While the I7+ Has a Runtime of 75 Minutes.

The size of batteries was once a significant issue in robot vacuums. But, since new features like recharge or restart for the Roomba 900 series, battery size isn’t as crucial as in the past.

Recharge and resume. When the Roomba runs empty of juice, it will stop and note the areas it has cleaned before returning to its docking station to recharge and clean in the same spot it left off after charging.

This makes the battery use less time since it will scrub your entire floor, no matter what.

The only situation in which battery life could play a significant role is when you have huge floor space and don’t want the Roomba to take the whole day to wash. But, the difference between 75 and 90 minutes isn’t much.

Difference 2. The I8+ Has the Virtual Wall Barrier; The I7+ Doesn’t.

Roomba I7 4

It is a Virtual Wall Barrier is a beacon you can place in your home to signal to your Roomba to stay out of the way. An excellent example of an area is near a pet’s water bowl, or any other decoration quickly knocked over.

But each of the models, the i8+ and the i7+, feature features like the “keep out zone” feature, allowing you to accomplish the same task with your phone. This feature makes a Virtual Wall barrier a nice-to-have rather than essential.

Difference 3. The Two Models Have Different Accessories.

The differences in accessories aren’t that big. The i8+ has four disposal bags, compared to five on the i7+. The i8+ comes with two additional high-efficiency filters, while the i7+ comes with only one other.

Let’s Look at the Similarities Between the I7+ and the I8+.

Similarity 1. Each of the I7+, as Well as the I8+, Comes With Intelligent Navigation and the Ability to Locate Your Home.

Because they’re the identical model, they come equipped with sensors and cameras to help you map your home and efficiently clean it. Smart navigation eliminates unintentional bumps and turns like the original robot vacuums.

After a couple of cleans, the vacuums understand the structure of your home. This lets them do their job more efficiently, making saving time and energy easier.

Similarity 2. Both Models Can Be Auto-Emptying.

Roomba I7 1

The Roomba i7+ and the i8+ can empty themselves once they have vacuumed.

Following each cleaning cycle (or realizing that the dust bin is empty), The Roomba I7+/i8+, it can be returned to the docking station, and the contents of the dustbin are taken out of the garbage bag at its docking station.

This means you only need to replace the bag of disposal when it’s complete. A great benefit for those who are opposed to emptying their trash bins.

Similarity 3. Both Have “Keep-Out Zones” and Specific Cleaning of the Room.

The Roomba i7+ and the i8+ are top-of-the-line Roombas with advanced features.

Keep-out zones are zones you create within your floor plan (using the iRobot application) to inform your Roomba to stay clear of.

If you’ve got a space or a specific area you don’t want to be cleaned, you can draw a line around it, and your I7+ or the i8+ can tell you to stay clear.

A specific room cleaning is the same as it sounds. Because Roomba is an intelligent device, and the Roomba is aware of the layout of your house, it is possible to name each room and instruct the Roomba to take care of that particular room, not the whole home. We find this feature to be beneficial.

For instance, the kitchen is often the one that needs to be cleaned the most. A specific room cleaning schedule lets us inform our Roomba to clean only in the cooking area (or master bedroom as well as the bathroom) and skip other home rooms.
