Roomba i7+ vs i7: What is the difference?

Roomba i7 vs i7+

The Roomba i7 and i7+ are two very similar product offerings, as this article will explain. When these two offerings were released to the market, iRobot had achieved a new incredibly high standard of robot vacuum technology that took even more effort out of cleaning. Although they have now been surpassed by the Roomba S9 and S9+, the i7 and i7+ are almost identical with the same standard of technology. This article will show you the minor differences between these two robot vacuums and explain exactly what the “+” adds.

1. Clean Base Station – The Game Changer

The principal difference between the i7 and i7+ which factors what the “+” is, is the Clean Base Station that is sold alongside the i7+. The Roomba i7 gets a more standard charging station called the Home Base. Essentially, the robot vacuum you get is practically the same except for one other minor difference. So what is so special about the Clean Base Station? Self-Disposal technology.

Self-Disposal Technology

This self-disposal technology was the game-changing factor about the i7+ that really shook up the whole industry. Effectively, after cleaning the Roomba i7+ can empty its waste into this unit so you don’t have too. As robot vacuums are all about taking the effort out of cleaning, this is an incredibly effective next step taken by iRobot. You will never have to empty the collection bin of the Roomba again, and the Clean Base bin can hold up to 30 cleans worth of waste.

Upgrading from the i7 to the i7+

As the principal difference between the i7 and i7+ is the addition of Clean Base, you can easily upgrade to it later. As the robot vacuum in each of these product offerings is practically the same, iRobot has made it very to easy to simply purchase the Clean Base retrospectively.

You should note that it is only the i7 and S9 at the moment which can have the Clean Base Station added it to make them the “+” version of themselves. This allows flexibility for you as the user to start out with just the robot vacuum if the extra Clean Base is too expensive or you are unsure.

Downsides of the Clean Base

You may be wondering as to who wouldn’t jump straight for the i7+ is the Self-Disposal technology is a clear advancement in technology. The first and more obvious downside is the additional cost and buying the i7+ only has a minimal monetary saving over buying the i7 and the Clean Base retrospectively.

Another issue is the noise of the Self-Diposal technology which is best placed in a side room or schedule to be done when you are out. Finally, it depends on how much the user cleans with their Roomba. If you find yourself cleaning rarely and don’t particularly mind emptying the bin of the Roomba once in a while, you might not be fussed. Eventually, the Clean Base has to be emptied and having it may not be worth the money if you clean irregularly.

Emptying the Clean Base

When it comes to emptying the bin, as ever with the iRobot app, a push notification will be sent to you when you are needed to finish the job. When you purchase the i7+ you will get 2 Dirt Disposal Bags included, although you will have to buy additional ones every month or two for $5 each in packs of three.

2. Collection Bin

This is indeed a particularly small and unimportant difference, yet should be mentioned. The Roomba i7+ has a slightly different material in its collection bin which makes it washable, although it must be hand washed and not placed in a dishwasher. On the other hand, the Roomba i7 has the standard non-washable collection bin with a style shared with the other Roombas. The size of the dustbins is in fact exactly the same.
