Roomba 700, 600 & 500 Series Comparison/Review (780, 770, 760, 610, 530, 532, 535/540, 550/551, 555, 560, 562, 570, 572, 580)

The 700 series is iRobot’s latest generation of vacuuming robots designed to work seamlessly on both carpets and hard surfaces. The initial robots were introduced in 2002 and the 700-series is their 5th generation version introduced April 2011. The most popular were the 500-series models introduced in mid-2007. A couple of 5-series robots (532 & 562) along with a professional series product called 610 were introduced in September 2008. The primary differences in technology between different 500 and 600-series models are:

• Lighthouse vs Virtual Wall Technology: Virtual wall technology allows Roomba to block off areas and lighthouse allows Roomba to navigate between rooms thereby allowing cleaning of multiple rooms efficiently –535 and above has lighthouse technology while the 530 has the virtual wall technology only. The new models from Roomba as of 2010 only include the Lighthouse technology on 570 & above models.
• Wireless Remote Activation– Allows Roomba to be controlled and scheduled remotely – Included with 570 and up. $59.99 upgrade for 535 and upwards.
• On-board scheduling – 560 and up.
• A high-capacity sweeper bin – this is new with the 532 and 562 pet series. It holds three and a half times the amount of debris that the standard one that comes with the other 5-series products hold.
• Max Mode – Allows Roomba to run until batteries are almost drained and then return to home base. This feature can be very useful to clean large open areas such as in an office floor.

It is possible that all 500 series machines can be upgraded to have the above features through a firmware and/or hardware upgrade, but iRobot has not made any such promises. The other difference between the models boils down to the additional accessories; power rating of the batteries included and/or replacement parts that are part of the package.

The new 700-series models have the following key technologies:

• The 760, 770, and 780 models have the dual-HEPA filters that capture dust particles as fine as 0.3 microns.
• The 760, 770, and 780 models have the AeroVac Series 2 bins that holds more than standard bins and also pulls debris and hair from brushes into the bin.
• The 770 and 780 models have the new Dirt Detect Series 2 technology that uses optical sensors to detect dirt and debris in addition to acoustic sensors used in the other models.
• The 770 and 780 models have a Full Bin Indicator.
• The 780 model has a Touchpad Control as opposed to Buttons in the other models.

• **550 – Occasional manufacturer's discount can reduce this price.
  
• Roomba 572, a new pet-series model was introduced in September 2010.
  

Roomba also sells certain models with technology from the previous generation as well as a number of remanufactured models. Re-manufactured Roomba's are available for between $50 and $100 less than their brand new counterparts. The downside is that they come with a 90-day warranty..

Our Experience:

Our purchase decision was made after reading the vast amount of information available at RoombaReview and Amazon.com. We settled on the 535 from Home Shopping Network as it offered the best upgrade path for the least amount of money. An additional virtual wall ($29.99 list price) was in the plans for us but after using it for almost two years, we have come to the realization that bells & whistles are not that useful:

1. The lighthouse and virtual wall technology – we tend to use it a room at a time and the door amply serves to keep the Roomba in. Even in an open floor-plan family area, it is easier to block access to certain areas than reaching for the lighthouse.
2. The self-docking capability – Roomba is usually transported to the desired location sans the dock and returned to the dock for charging.
3. The scheduling interface and the voice demos - The remote for the scheduling option is beyond the scope of our purpose and the voice demo was used only the first time and its real value is moot.

Roomba performs better with a certain amount of preparatory work. This could involve such things as moving light furniture like chairs out of the way, picking up bigger pieces of garbage, dusting down furniture and baseboards, etc. Not all of it needs to be done every time as Roomba is able to handle most obstacles, albeit less efficiently.

Unlike with a vacuum, it makes a lot of sense to use the Roomba frequently – it involves minimal work on your part and the Roomba does its thing while you leave it alone and does not require light. Further one can quickly warm up to the fact that Roomba is relatively quiet and cleans hard-to-reach areas. It is best to clean up the brushes, filters, and empty the debris bin after every run. This takes less than 5 minutes and the modular design along with the fact that Roomba is light makes this less of a chore than it sounds.

Following is a summary of some of the cons we have noticed:

1. Roomba does not suck in pencil point tips. Instead it drags the Pencil tip and leaves pencil marks all over our laminate floor. We usually use an eraser to get it off,
2. Roomba misses certain spots,
3. Transition strips that are between our laminate and tile floorings are problematic for the Roomba, especially when the tile area is very small as around our fireplace & entrance – it attempts to get over it and in the process bumps on the wall turns back and the process continues.
4. Roomba was a little bit hard on one of our glass cabinets as the bumping is not that light. We use the lighthouse for these purposes.
5. The adhesive on the bumper pad does not stick on easily.

Replacement parts are sometimes back-ordered. This is something to watch out for. One solution may be to keep one set of replacement parts handy.

Best Value Recommendation:


The 700, 600, and 500-series Roomba’s are excellent products that can save busy households’ valuable time. Among the Roomba 500 & 600 series models, our recommendation is to go with one of the basic models: Roomba 530 or Roomba 532 PET. Among the 700-series models, the best value is the Roomba 770 - it incorporates all the new features in the 700-series with the room-to-room navigation virtual lighthouse technology and the touchpad control as the missing items compared to the top-end 780 model which is priced at $100 more.
