The future is now with the iRobot Roomba 620. It may seem like a thing from The Jetsons, but this is currently available in the market and anyone can have one at the right price. The device is manufactured by iRobot, a robotics company that has over 20 years experience in robot design and development.
They have built robots that have gone to war, through storms, below deep oceans, and outer space. It is important to note that iRobot is not an electronics company, but one that specializes in robotics, so one can be sure that the iRobot Roomba 620 is intelligently planned and designed.
Unlike other vacuum cleaners, it is obvious that the iRobot Roomba 620 has a much more compact design. It runs on a single rechargeable lithium-ion battery, and is programmed to run using the least possible power. It is light and portable, and it can be easily carried around from one room to another unlike traditional bulky upright cleaners. The robot has multiple sensors that help it recognize its surroundings as well as automatic cleaning adjustment depending on the type of flooring. It can also detect areas that require more cleaning so it can dedicate more power on those spots.Click Here for Latest Prices
Out of the box
The total package of the iRobot Roomba 620 weighs around 8 kg, so it’s worth noting the shipping weight if you are going to order this product online and have it delivered straight to your door. This is rather bulky but the unit itself isn’t that heavy. In fact, it weighs around 3.6 kg. That’s roughly a little over 6 pounds. The unit comes with an instruction manual, a red cleaning tool attachment, and a charging dock and cable.
There is also this neat device called a virtual wall that sets a limit where the device can clean, but this is sold separately. All components are individually wrapped to avoid surface scratches and damage.
The device measures 34 x 34 x 9.2 cm. Its low height enables it to sneak under beds and low furniture without having to move them aside. The unit is also very light at a little over 6 pounds, and can be transported with ease with its folding recessed handle. The handle partially surrounds the main power button, which glows a bright neon-green when turned on, at the top of the device. Next to this is another button that releases the waste bin when pressed.
The bin’s capacity covers less than half of the total volume of the device, which may require the user to dispense the dirt every so often if he or she expects a heavy cleaning job. Nevertheless, this bin can hold small bits of hair and dust from light cleaning. Off to the side is the charging port.
The device has a main rotating brush beneath to pick up loose dirt and debris. Next to the brush is a rotating rubber squeegee to polish off any remaining smudges on smooth flooring. Flanking the rotating brush and squeegee are the two rubber wheels that move the device around. Just off to the side is a rotating brush-tipped wheel that sweeps more dirt towards the main rotating brush and squeegee. To the front is a swiveling wheel that intelligently steers the device wherever it wants to go.
The Roomba 620 runs on 33 watts of power, and can last up to 80 minutes on a single charge. Charging the 3,500mAh battery takes about 3 hours and does not really take a lot of time.Click Here for Latest Prices
iRobot did not hesitate to load the device with several features for convenient cleaning. It has several sensors that enable it to adapt to unfamiliar environments. The Roomba 620 has the updated version of iAdapt that gives it an idea how the rooms in your home are laid out. Though initial runs of the Roomba 620 started slow with a few bumps, the robot quickly learns from its mistakes after multiple passes.
The sensors also let it adjust its settings to match the flooring material so it can avoid surface damage. The soft bumpers at its sides also absorb the small shocks from bumping against walls and furniture. The robot does not only avoid damaging them, but it also prevents internal damage of its sensitive components.
Dirt Detect technology lets it pick out dirtier spots so it can focus on those particular areas for spot-free results. Dirt Detect makes use of an acoustic sensor that makes sure no spot of dirt, dust, or pet hair is left untouched.
The robot’s motor is powerful. AeroVac Technology maximizes airflow such that even the most stubborn of particles get drawn into its removable waste bin. Dirt collection in the bin is also evened out, making the most out the bin’s capacity.
The rotating brush, squeegee, and the rotating brush-tipped wheel just off to the side all work together to pick up as much dirt as possible. The new design of the brushes has significantly lessened the amount of hair tangle. These parts are also conveniently removable should you plan to clean them.
Pros and Cons
Cleaning performance for the Roomba 620 is exceptional when it comes down to cleaning robots. It makes the most of its included features giving it a quick learning curve when adapting to new environments. iAdapt and the soft bumpers prevent damage to fragile surfaces, and also ensure spot-free cleaning. The battery life of the Roomba 620 is also impressive at 80 minutes at a single charge.
Charging only takes 3 hours. The robot also has this neat feature where it goes straight to the charging dock when it has finished cleaning or needs to recharge. The design of the 620 is a refreshing take on its predecessor, which is the 500 series. The curves and lines are cleaner and complement each other more.
The bin is cleverly hidden among the curves and fits flush along the sides. The colors are more modern, and are accentuated by the green glow of the power button when the device is activated. Finally, the price is reasonable. Top of the line models may be valued at a little over £600. This is ridiculous compared to the £250-£300 value of the Roomba 620.
However, there may be a few imperfections that a few may find deal-breaking. First, the Roomba 620 has no on-board scheduler like some other robot vacuum cleaners we have reviewed , which means the robot has to be activated manually each time. Virtual wall ‘lighthouses’ that limit areas that the robot can access are not included in the package. These have to be purchased separately. Finally, there is no indicator to tell if the bin is full. It has to be emptied every once in a while to prevent clogging moving components.
The iRobot Roomba 620 is a clever machine that is a significant upgrade to its predecessor. It is fairly priced for an entry-level machine, and has intelligent features that present remarkable results. Though the machine can work on its own, it still requires manual checking of bin load, activating of the device, and proofing of certain areas like loose doors so the machine does not accidentally bump into them and lock itself in the room. But with a few minor inconveniences aside, the iRobot Roomba 620 is worth every penny.
