What Does The iRobot Roomba i7 7150 Offer?

The iRobot Roomba I7 7150 is a fairly elaborate robot vacuum that offers a number of excellent features and settings. To use this robot vacuum, you’ll be relying on your smartphone – or another Smart Device, such as Amazon Alexa or Google Assistant – and this gives you access to the features and settings that are offered.

On your smartphone, you can do things like create a custom schedule for the robot vacuum, change the cleaning mode, tell the robot vacuum to recharge, turn it on and off, and access a map of your home. Having access to that map is an incredibly useful feature, as it gives you the ability to see where the robot vacuum is, at all times.

More importantly, it allows you to choose exactly where the robot vacuum cleans, and where it stays away from.

With the map, you can choose specific rooms and spaces that you want the robot vacuum to clean. So, if you want the robot vacuum to clean a bedroom, you can choose that bedroom on the map, and it will clean.

You can also choose spaces and areas that you don’t want the robot vacuum to clean, so that it will then stay away from them.

While having access to that level of control and functionality is excellent, this robot vacuum also offers some excellent performance. Through the use of a very powerful motor and an incredibly useful brushing system, this robot vacuum is able to easily vacuum on hard and soft floors.

If you are vacuuming on a hardwood floor, for example, then all of the dirt, dust, and small pieces of debris on that floor will be removed. And, even on a soft floor – such as a rug or carpet – where the surface is very thick and dense, the robot vacuum has no problems removing what’s on the surface.

If you are looking for an excellent robot vacuum that gives you complete control over the vacuuming process, and plenty of power, then the iRobot Roomba I7 7150 is a fantastic purchase!

What Does The iRobot Roomba S9 9150 Offer?

The iRobot Roomba S9 9150 offers many of the same basic features and design traits that the previous Roomba offers. But, it also offers greater suction power, stronger brushing power, and a very nice dirt disposal feature.

To use this robot vacuum, you can use your smartphone – or an Amazon Alexa or Google Assistant device – and you have access to all of the features and settings that are offered.

This includes things like creating a custom schedule and telling the vacuum to recharge, as well as the mapping feature that the I7 7150 offered. That way, you can determine where the robot vacuum goes and what, specifically, it vacuums up.

What really sets this robot vacuum apart, though, is the fact that it has an automatic dirt disposal feature.

When the vacuum has a full dirt-tank, it will then go over to a dirt disposal dock, where all of the dirt that is in the tank will be removed. Then, the robot vacuum will go back to vacuuming.

This is such a convenient feature, as it ensures that the entire vacuuming process is completely automated.

There is no need for you to do anything except turn the vacuum on and allow it to work, because the vacuums works on its own and is capable of performing all of those little functions by itself.

As for the power and efficiency that this robot vacuum offers, it offers a significant amount more than the I7 7150. This is easily one of the most powerful robot vacuums on the market, and all of this power allows this robot vacuum to easily remove just about anything on any surface.

For example, if you need to vacuum up pet hairs from a thick rug, then you can use this robot vacuum to do just that. It doesn’t matter how dense the surface is, or how messy your home is, this robot vacuum can easily vacuum it!

Ultimately, if you are looking for power, efficiency, and convenience, and you don’t mind spending a fair amount of money for it, then the iRobot Roomba S9 9150 is fantastic!
