Perhaps no brand is as easily identified with the robotic vacuum, particularly with that cutesy circular shape so many of the bots have taken in their years on the market, than iRobot's Roomba. Countless versions have sprang up and been put down over the years, resulting in the current marketplace of a few seemingly random numbers still being carried and produced by iRobot, and with many of the others still available through secondary retailers. For example, the 980 is the newest of the new out of the Roomba line, so understandably iRobot still carries it, whereas the rationale for keeping the two-year old Roomba 650 up on the site (as a sort of bare bones option) seems questionable when reviewing the multitude of other Roomba products that didn't make the cut.
In trying to sort out the reasons behind why iRobot does these things, one thing does become clear: a number ending in a five signifies a pet-ready edition of the Roomba. The 585 is a fairly old model, but seems to hold up well, selling with a variety of resellers across the internet. The 500 series as a whole was launched in 2007 to widespread acclaim, reigning as a Roomba favorite for five years before being usurped by the 600 series. There's really no thrilling changes from generation to generation to point to — rather, iRobot improves on their winning product incrementally year in and year out. Meaning if you're not looking to spend just under $400 on the newest of the bargain end of the Roomba lineup, digging through some of the old favorites like the 585 may be just the bargain you're looking for.
This robot is great, but I wish the vacuum were stronger.
This vacuum is wonderful it really does work. I am the biggest clean freak and have very high standards. This has exceeded my expectations.
Very easy to use really happening everywhere including under the beds. Maintenance is pretty easy and use also. I recommend this product.
If you are looking for an extra cleaning, this robot is perfect, there will space the big cleaning sessions. Easy to use.
Good little vacuum. Does a better than expected job of keeping the floor dust free. Even letting it do-its thing once a week will fill its dirt catcher.
The unit has worked well. It has more powerful suction than my two name-brand uprights. It pulls material from the the carpet and the pad.
