I love my Scooba. I had a problem with the battery as well soon after I purchased it. The customer service was excellent and sent me a new battery. I had left the battery running too long for the unit but since it was under warranty, there was no problem sending me a new one as well as a piece that lets me keep it plugged in for 2 weeks. In my last house I had a large space with tile and unsealed grout. The Scooba did a fantastic job cleaning it. I got the Roomba as a freebie when I purchased the Scooba but I haven't tried it yet since I have a Dyson. In my new place, I have hardwood floors and I will be trying out the Roomba here. I'll let you know if I love it as much as my Scooba.

Mine goes until its wheels fill up with fuzz and then it asks me to "Clean Roomba's wheels." I do so and it goes merrily on its way. Several hours total. Our gameroom carpet is very difficult to vacuum; it has an extremely deep pile and pad and acts like Velcro to lint, animal hair, etc. In a perfect world, I'd tear it out, but it's in good shape, so I'll wait.

I LOVE, LOVE, LOVE my floor robots! I have a couple of Roombas and a Scooba. 1) Do they really know how to navigate so as to not keep retracing their "steps"? They do retrace their steps to some extent. I used to worry about it, now I just let them do their thing and see the results at the completion. 2) Does Scooba leave any standing water? No. A little bit of dampness to dry, about five minutes. 3) Scooba's so small. Don't you have to keep refilling? I have one that goes for nearly an hour, I refill it once during that amount of time. 4) Has the Clorox cleaner been ok for your wood floors? Sorry, I don't have wood floors. 5) They're really expensive. Worth it or no? I LOVE, LOVE my Roomba. I really LIKE my Scooba. If I could only have one, it would be the Roomba. 6) Any mechanical problems? Like a wonderful pet, they are great but do require some care. I empty my Roomba each time it runs (I have five boxer dogs) and I clean its brushes about every three runs. Maintenance is easy and takes a few minutes. Beyond that any problems I have had (few) have been quickly repaired by iRobot sending me a new part. 7) If they get stuck and you don't notice it right away, do they eventually turn off? Yes, they call you first (beep, beep). If you ignore them, they turn off/wait. 8) One of my issues is pet hair; any probs there? Well, I have five dogs, LOTS of hair even though they are boxers. I don't mind paying for something that works, but these days, it seems like everything I buy is a cheap piece of you know what. If you belong to Costco, they sell the Roomba and are VERY good about returns. Also, Hammacher Schlemmer offers a Lifetime Unconditional Guarantee on EVERYTHING they sell, and they sell iRobot products. I wish I had known about them before I bought through Home Shopping Network. There is a Roomba chat sight where many people have bought and had their units replaced through Hammacher Schlemmer. You can see the guarantee on their home page. I would no longer be without my Roombas! Here is a link that might be useful: Unconditional Lifetime Guarantee

I agree with jodi in so calif "I wish everyone who has one sitting lonely and forgotten in a closet would just send them to me. I'd name it, get it "fixed", and give it a loving home." Heck I'd even pay for the shipping ticket. And my little Wascel would have more friends. :-) Seriously if you have a roomba and need a battery there are options available. Irobot has 3 different batteries for the 400 or discovery series Roombas, The original 3300 mah battery the APS is $69.99 it charges in under 3 hrs and lasts approximately 2 hrs per charge. the 2200 mah bettery is $59.99and charges in about 2 hrs and lasts about an hour and a half then there is a 1800 mah battery for $49.99 and ic lasts between 45 min and an hr after a 2 hr charge time. You can call and order by phone or you can order online at the Irobot website. A referral email will also get you 10% discount of the merchandise amount. Buying one on Ebay may not get you a new battery and it most certainly will not be under warranty from Irobot so if you are prepare to lose all your money with one bad seller do the Ebay thing. I would rather pay the for a new and good one from Irobot with the warranty and return options available. I love having the little guys around. I don't ever worry about vacuuming or sweeping so I can run barefoot in my house. My oldest one is nearly 3 years old, still has the original battery and working fine. The newest Irobot 500 series does'nt get tangles in the throw rugs or cords so no more picking those up and there is a trade in program if you are a registered 400 owner you can get a discount of up to 30% for a new model. The battery last longer per charge and charges even faster than the APS from the 400 series. CT
