LG Hom Bot vs Roomba 790 – Which is the Best Option?

For most people, when it comes to cleaning their home, there is usually a time block allotted each week to complete the task. For most people, schedules are filled each week and are so busy with work, chores and activities for their children, the allotted time block might not be in the same day each week.

Times are certainly different from when mom would spend four hours every Saturday morning cleaning the house religiously. In the current times when technology has been enhanced to work in the favor of the consumer, one of those advances has come in the form of robot vacuums.

Robot vacuums, much like most electronic items in the past 10 years have advanced drastically and have made cleaning your home easy to do and essentially hassle free. Some of these household appliances have been made to program themselves around your furniture, steps and other hazards, while sensing where the dirt, dust and debris are.

Among the premiere units on the market now are the iRobot Roomba 790 and the LG Hom Bot 3.0. What are the top features of each robot vacuum and how do they compare? This article will delve into the HomBot vs Roomba debate.

Features of iRobot Roomba 790

The iRobot name is one of the most trusted in the industry and is the creator of some of the most innovative features in the robot vacuum industry. With the Roomba 790 – one of the newest in the large line of iRobot vacuums – users will get all the usual features expected from the vacuum, plus more advanced features.

The Roomba 790 is equipped with a three-stage process that is designed to clean just about every surface imaginable from hardwood and tile to linoleum and carpets. The vacuum can go from one material to the next on its own and automatically adjust its settings to accommodate the surface it needs to clean.

Those looking for a portable vacuum to help clean up any pet hair or dander don’t need to look any further for their model. The Roomba 790 is made with a cleaning head that is designed specifically for this type of debris, ensuring the device won’t need to go over an area more than once. The vacuum is powerful and pulls all debris off the ground and directly into the bin. This iRobot unit is also designed to ensure that the unit never gets clogged, something robot vacuum owners have complained about excessively in the past.

Robot vacuums were created to make the entire cleaning and vacuuming process easier. Before these devices were invented, you used to strain your back to vacuum under your coffee table or bed with a conventional vacuum. The Roomba 790, much like other vacuums on the market takes the pain out of cleaning. What helps set this vacuum apart from the competition is its state of the art sensor system that tells the device when there is an obstacle to avoid. The internal memory can update automatically, so you won’t need to worry about keeping your couch where it was previously.

With the iAdapt Responsive Cleaning Technology, the environment in which the vacuum is operating is being monitored and checked constantly to ensure every surface is cleaned thoroughly. The Roomba 790 does this with sensors like the cliff detector that are made to create a clean floor. This device is made with soft-touch bumpers to protect itself, as well as the furniture, molding and other objects. Another sensor that Roomba 790 features is called the Dirt Detect Series 2. This sensor uses acoustic and optical sensors that are designed to find dirt and debris. In those areas that are considered the dirtiest, the vacuum will detect the increased debris and focus on that area for an extended period of time, much like you would with a basic vacuum.

iRobot also added a new feature to the Roomba 790 that will keep the device in a single room until it is cleaned up to par. In between uses, the device will automatically take itself back to the home base to charge. Users can tell the vacuum when and where to clean by using the wireless command center. With this center, you can schedule the unit to work in any room at any time of day. You can schedule the Roomba 790 to run seven times a week and with its new upgraded battery life management system; you can get hundreds of more uses in its lifetime.

UPDATE: The Roomba 790 is no longer readily available. In terms of a replacement, I’d recommend checking out the Roomba 780 or Roomba 860.

Features of LG Hom-Bot 3.0

The first thing you will notice about this robot vacuum that sets it apart from others is its shape. When most robot vacuums are made with a circular design, the LG HomBot 3.0 is square, allowing it to get into the tough to reach corners with more ease than others. The vacuum is built with longer brushes that come out of the square sides that allow it to reach the areas that circular units struggle to get.

One of LG’s selling points for the HomBot 3.0 is that much like humans have two eyes when they are using a manual vacuum, so should a robotic vacuum. The LG HomBot 3.0 was constructed with cameras on the top and the bottom, both of which are designed to track and map its route. By doing this, it will create the best path to cleaning your house in the future.

The LG Hom-Bot 3.0 features seven different cleaning modes for whatever cleaning needs you desire. The unit is pre-programmed with seven smart cleaning modes for use in cluttered rooms, or large open rooms without many obstacles. This unit has a setting that will automatically adjust its mode depending on the floor material it will meet in a room including carpets and hardwood flooring. A major selling point for the LG Hom-Bot 3.0 is that is operates quietly as it was made to reduce noise by absorbing the vibrations that can become an annoyance.

The LG HomBot 3.0 is a unit that knows where it left off should it ever get obstructed and sent to another part of the house. By simply enabling the auto-resume option, the LG HomBot 3.0 will return to where it was stopped previously and will clean the initial area. This is just another feature that shows the impressive technological advances in the market. Among the other features is its ability to remember the path it took to optimally clean a room each time.

iRobot Roomba 790 vs. the LG Hom Bot 

A lot of the current robot vacuums readily available on the market today feature similar technologies to each other. Just like with other technology advances, it is usually one company that sets the pace for how quickly the market changes and since iRobot began producing the Roomba, they have been that company. When you look at these two units, it is easy to see their similarities and differences. The most obvious difference is their shapes, but they have many common features from their ability to automatically adjust to different floor types to the sensors used to create a blueprint of the home.

When it comes to which unit will do the best job for you and your home, it all depends on what you need your robot vacuum to do. If your home is filled with pets, the iRobot Roomba 790 might be the best tool in your fight against pet hair and dander. The iRobot Roomba 790 will also be your best bet if you are looking for a more convenient option for your household cleaning because of its ability to schedule up to seven different runs each week. While you are home, at work, sleeping or awake, by going through the wireless command center, the Roomba 790 is filled with surprises.

The LG HomBot 3.0 is a reliable robot vacuum that has its positive features as well, including its height. Since it is only three inches tall, it can fit under any piece of furniture in your home and with its square shape, you won’t need to worry about keeping your dust pan ready.

While there is no clear winner in the Roomba 790 vs Hom Bot 3.0 faceoff, there are some clear benefits depending on what features you value most.

UPDATE: Since the Roomba 790 is no longer carried at most retailers, I would recommend checking out the Roomba 780 here or the 860 here. Similarly, the Hom-Bot 3.0 now goes by the name “Hom-Bot Square” which you can find here.
