Reasons To Buy The iROBOT ROOMBA 665

Dual Multi Surface Brushes

One of the best parts of the iROBOT ROOMBA 665 is that it comes with dual multi surface brushes. Now you must be thinking why it is so special?

Well, you must know the fact that iROBOT ROOMBA 665 is one of the few cleaning robots which comes with two brush cleaning systems.

Even both of the brushes work simultaneously. As a result, you will be getting a better cleaning experience. At one side one brush is designed to release dirt, and the other brush is designed to collect it.  As a result, you will get to see a clean floor with zero spots.

Dirt Detection and Cleaning Technology

It comes with dirt detection and cleaning technology. Dirt is one of the main reasons for many problems. Hence it is always a good idea to keep them away from your home.

But doing so can be a tough job. But do not worry, the iRobot Roomba 665 comes with the dirt detection sensors. These sensors are capable of identifying where the dirt is as well as clean them. So you will not have to do the hard task by yourself.

3 Stage Cleaning System

It also comes with a 3 stage cleaning system and works along with the multi-surfaced brushes.  The robot is capable of cleaning the floor effectively using a high suction power.

As a result, the vacuum suction takes the dirtiest clogs from the darkest corners of your room. No matter if it is small dirt or a stubborn one. The robot will make sure that there is no dirt left at all.

Adjustable Head

It also has an adjustable head. In order to make the brushes intact, the machine comes with the auto-adjustable head. The head keeps on moving.

The robot needs to make contact with the floor consistently. So if the robot is moving from one surface to another, it needs to adjust instantly, and this is where the adjustable head comes into play.

If you are planning to clean a carpet and wooden floor at the same time. Then simply hand over the job to this machine and it will perform in the best way.

You Can Schedule Your Cleaning Timings

With the help of the iROBOT ROOMBA 665, you will be able to schedule your cleaning timings.

The robot allows you to schedule your cleaning as per your requirements or you can perform manual cleaning. For manual cleaning, all you have to do is press the clean button, and you are good to go.

But in case if you are way too busy. Then you can put the machine into the schedule mode and do all the necessary settings as per your requirements. And the robot will follow your instructions.

It Automatically Recharges Itself

The best part of the iROBOT ROOMBA 665 is that it automatically recharges itself. The robot is capable of finding its way back to the home location and recharges itself automatically.

So you will no longer need to take the robot to the charging dock and plug it. Instead, the robot will go to the dock and charge itself and be ready when you need the robot for the next cleaning job.

It helps in saving time and energy a lot. Plus, you won’t have to care about charging the robot again and again.

Removes All Debris Type

The robot is also capable of removing all types of debris from different parts of the floor. The iROBOT ROOMBA 665 will follow the wall borderline and look for debris and clean it on the go.

The machine is programmed to remove all types of debris than any other vacuum cleaner on the market is programmed to remove. But the thing about the iROBOT ROOMBA 665 is that it offers you quite a lot of extra features which is perfect for your home.

Has An Intelligent Navigation System

In the end, it comes with an intelligent navigation system. The robot is programmed in such a way that it is capable of making 60 decisions per making.

With this robot, you will be able to understand the power of AI. And that is the only reason why this robot is powerful compared to many other options in the market.

Once you start using this machine, it will easily adapt to your home’s cleaner settings. It will figure which areas need maximum cleaning and do it in the appropriate way. And all these things are possible because of the smart navigation feature that the iROBOT ROOMBA 665 has.

Virtual Wall Barrier

There is also a feature called Virtual Wall Barrier. Although, this is an optional feature but is quite useful. So the question in which way it is useful?

Well, the virtual wall barrier simply removes the boundary of the robot. As a result, your iROBOT ROOMBA 665 gets opened up for lots of possibilities. It also has two modes. And these modes are the:

Virtual Wall Mode:

When you turn on this feature, you will be able to make a barrier of 3 meters, or you can say 10 feet on an open space. And your iROBOT ROOMBA 665 will work in this specified area only. This is a pretty useful feature when you want to save your robot fall from stairs.

Halo Mode:

Next, there is the Halo Mode. If you turn the switch down, it will enable the halo mode. This means that the accessory will create a protective zone where the iROBOT ROOMBA 665 cannot enter. You can set this 24 inches from the device.

However, when you are not using any of these features, I would suggest you to keep the switch in the middle. As this means that the robot is not into any of these two modes.

Warranty and Warranty Claim Information

The best part is that the iROBOT ROOMBA 665 comes with one year of limited warranty. And claiming the warranty would not be a tough job to do. As customer support is pretty great and they will offer you pretty fast service. Just go ahead and call on their customer care and they will guide you with the rest.

However, there are certain cases where the company does not offer you any warranty. So before you get the cleaning robot, it would be a nice idea to know the things. So you can use the robot in a safe way and avoid misfortunes.

  • The company won’t offer you any warranty for wear and tear.
  • If the robot faced any damages because of any accidents, misuse, inappropriate handling, fire, water damage or any other thing. Then you will not get to do a warranty claim.
  • If there is any sign of battery tampering.
  • You cannot use any spare or replacement parts for the robot when it is under the warranty.
  • If you do not buy the product from an authorized dealer, then there is a high chance that you might not get a warranty. As unauthorized sellers often fail to give you a warranty.

So these are some of the top cases where the company will fail to offer you a warranty. Apart from these reasons if your robot stops working suddenly or got a damaged product. Then you get to claim your warranty. Also, if you purchase it online, then you will always have the chance of returning your product within a time set.
