iRobot Roomba 770 vs iRobot Roomba 620: Are the Improved Performance and Cleaning Abilities Worth the Money?

Features and technologies

Being an advanced iRobot vacuum, the 770 model comes with several beneficial technologies, such as:

  • Virtual Wall
  • Dirt Detect 2
  • 7-day scheduling
  • remote control
  • AeroVac2 cleaning system

It is equipped with a full bin indicator, HEPA filter, being programmable and smart. The vacuum removes 98% of dust, dirt and pet hair from all floor types, following Persistent Pass cleaning pattern. On the other hand, comparing iRobot Roomba 770 vs 620, I would say that the basic model has virtually no benefits in terms of performance and features, but for the larger dustbin. It is equipped with Ni-MH battery that is longer to recharge, but safe and more long-lasting in operation.

Design and Specifications

Having the similar round shape, the popular Roomba vacuums still have some differences in terms of design. The advanced, 770 model is more lightweight and low-profile. It is black, being minimalist and elegant. Meanwhile, some users think that the 620 model’s casing is more hard-wearing, as it’s not sleek.

Price and popularity

Considering Roomba 620 vs Roomba 770, we see that the basic, 620 model is more affordable, and the difference in price is very significant. Therefore, it has a bit higher rating, while both vacuums are bestsellers.

iRobot Roomba 620 Review

Being one of the least intelligent and the most affordable iRobot vacuums, the 620 model comes only with several basic features, including:

  • wireless charging
  • anti-fall sensor
  • self-docking technology
  • Dirt Detect

It doesn’t fall off the stairs, but the vacuum is definitely weak in navigation. It has poor cleaning abilities, being a bit noisy and not too powerful. Quite naturally, the vacuum is not the most efficient on carpets and rugs, but it is still designed for all floor surface types. Therefore, I would recommend the model for beginners and large house owners.

iRobot Roomba 770 Review

Coming with a number of innovative technologies, the vacuum is extremely efficient, smart and performant. It eliminates dirt, dust, pet hair and cat litter spots perfectly well, from all floor types. The model is lightweight, low-profile, easy to maintain, but very expensive. So, paralleling Roomba 620 vs 770, and selecting one of the vacuums, I would take into account the family budget, the house size and the cleaning needs, that is, the necessity of air filtration, spots elimination, etc.
