Pros: Sorry I see none! They need to take this one back to the drawing board. Oh it move by it's self. Took a chance but sending it back.
Buy a wet mop and get better results and a workout at the same time.

Cons: You have to buy a clean reservoir that should have come with it cost $40.00. While it is ten inches wide it only wets a 4 inch stripe while cleaning. It keeps stopping and you have to restart it. It never cleaned one room before battery needed charging.

Other Thoughts: I have had a Roomba for five years and it workks great. Only had to replace the battery once, it is used a couple of times a week. it also finds its way back to the charger by it self. The best thing is Newegg's return policy.

Pros: I have mainly used the quick mop setting and the battery lasts from 2-3 hours! So it can do several rooms on a charge. You just need to reset the laser navigation position. I am also impressed that it does a good job on rather uneven slate tiles.

Cons: Even with a relatively clean floor, you'll need to pause the bot and wash out the micro pad every 30-40 minutes as it gets quite dirty. Also, you need to create a barrier near stairs as the sensor can fail, resulting in a tumble.

Other Thoughts: Overall, I do like this machine and use it lots. As far as recommending any changes-If there was a way to add some spinning action that would assist with dirt build up. Certainly having it increases the likelihood that the floor gets washed, so I would recommend the product .
