Bests & Worsts Reviews from Amazon

This is my 3rd Romba. Wore one out, bought another, and got this one to review. So, currently have two. I think they are both 600 series because this model 652 is almost exactly like the other one. Being that I replaced my first Roomba with another is a sure sign that I really like these things. They work. They rarely get stuck. They get back to the charging station. The dust bin is easy to dump out. The bot itself is easy to clean out. I have tested others and they ended up donated to Good Will. They were too inferior to tolerate. Comparing the two, the 652 feels quite a bit lighter. Not sure why (yet). Other than that, the spinning brush bits are interchangeable with the older model. Front roller is the same. Lots of stuff is the same. To test it, I pulled the other Roomba off the charging station, plunked this new one in its place, waited for it to charge, then hit the "clean" button. The new bot seemed to run longer than the old bot. That's probably why its dust bin was crammed full of stuff. Maybe it was the new brushes and new battery. Dunno. It did a great job. This 652 model is super basic. There is one spare filter in the box and no spare brushes. My others came with more spare bits. Those were purchased at Costco. I think that all the "600 series" models are the same bot but with different amounts of spare bits and maybe some light walls too. So, this particular model is about as basic as you can get. This is not a problem as I've run the same brushes for years and only changed them out when they got so filthy from -something- that I didn't want to deal with them. Summary - this is a great little vacuum bot -but you might want to consider a model with spare brushes because otherwise you'll wait a few days for new ones if the old ones get disgusting.
