Using vinegar every once in a while is good for helping to clean out the system a bit

Notice edge cleaning is all about the squeegee and not the brush?

Brush is further away than the result IMO.

The squeegee is not fully to the edge, and the robot also can't follow the wall perfectly, so some more gap there.

By contrast the are a couple inches from edge to brush which is more than I'm seeing (unless it's perspective and I can't tell as well as I think)

Hi,

I am new here. I have been using Roomba model 531 for about 2 years and I am quite happy with it. Last week, I bought Scooba 450 and I am facing two major problems.


Problem 1 - Very Wet Floor

Scooba 450 has two options - large room to cover area up to 300 sq ft or small room to cover area up to 150 sq ft.

I tried the large room option in my living room of about 300 sq ft with 3 study tables there (I removed all the chairs). At the end of the cleaning cycle, about 40 to 50% of the floor was very wet that I had to mop it manually again.

I tried the large room option in my master bedroom of about 200 sq ft with a small walk-in wardrobe, 20 to 30% of the floor was still very wet at the end. Again, I had to mop it manually.

Scooba 450 wets the floor first, scrubs and then finally dries it. During the drying cycle, it may miss out certain parts and hence leaves a very wet floor, especially with furniture like tables and chairs around.

So, the only solution I could think of is to clean a small area only using virtual wall each time and try to remove furniture (which I find it impractical) if possible. I feel that I am better off using the manual mop. Sigh...

Problem 2 - Leaving more water at the end

At the end of the cleaning, Scooba 450 "shakes" off the water to dry itself and it is supposed to do a final spin to suck up the water it shake off but my machine seems to spray water instead during the last part. It hence leaves a small circle of wet floor. The machine is so wet that the water drips from it when I lift it up. Is my machine faulty? Or is it a design problem?

Could those who have used it share if you have the same problems? Is there any solution to the problem?

Thank you for your help.

The Scooba 450 is still a very new robot and therefore not many users yet. I have the 450 and using the large room choice in a 12' x 25' kitchen with linoleum flooring and removing the kitchen chairs I do not have really wet floors that need additional mopping when the Scooba has finished its task. And the flooring dries within 15 minutes.

You may want to contact iRobot about a warranty replacement.

450 features 'pre-soak', so maybe this is...

The "pre soak" is just a marketing joke: Contrary to the scooba 3xx, the 450 has the water spraying jets behind the vacuum sqeegee (230: before it). So, at the first drive over an area, it puts water on the floor and on the scond pass this water is used for scrubing and vacuuming the dirty solution. (in short: no "active" function but only a mechanical fact) .

If your floor is VERY wet after cycle is finished: have you already measured the amount of dirty water, Scooba collected in the tank? My first unit collected between zero and 10ml. I returned it and received a complete new one. This one has about 350 ml of dirty water in the tank after a complete cycle an leaves the floor clean and nearly dry, as it should be!

Hi,

Thank you for all your replies. I maybe getting an exchange from my seller. I am thinking if Scooba 390 is better for my house. Can those 390 owners tell me whether you face the wet floor issue?

I am okay if the machine can only clean 60 to 80% compared to manual mopping but I don't want to do any extra work like mopping the wet floor manually again after each use. It just does not make sense to me as the robot is supposed to help not create extra work.

Thank you very much.

The "pre-soaking" feature is a huge mistake because the robot fails visiting all 100% of the "pre-soaked" area, leaving a wet floor. I'm waiting for the next model, without this feature. Very disappointed :(

I own a 385 and a 450, and I can tell you, that there is no "wet floor' issue with the 450, when it is a correct working device. In direct compare, it leaves the floor more dry than the 385

I run a 5800, 5900, 390 and a 450 and I have to report that even though my favorite Scooba used to be the 5900, it is now the 450. Besides the ease of use, from tank filling and emptying as well as simplicity of cleaning of the robot. There is the added convenience of now being able to use a single battery type for both your 500 - 800 model Roombas as well as your new 450 Scooba. And then pile on top of that you now can convert to a LI-ion pack. :cheers:

Don't you have this wet floor problem?
I live in a very small and (shame on me) cluttered apartment, and I don't see how the new Scooba will manage with wiping of all water.

Hi

Quite surprised that some do not have wet floor problem. Does it mean that my machine is faulty? For those 450 owners without wet floor problem:

1. Do you remove furniture like table and chairs before mopping?

2. How big an area can your machine cover for large and small room options respectively without leaving a wet floor?

Thank you.

Running the 450 or any robotic floor cleaner will require some prep first. How would you mop your floor now using a mop & bucket ? Wouldn't you pick up chairs, and other clutter before starting your cleaning routine ?

When the 450 is done in my kitchen, the floor is not dry, there is a thin layer of moisture but it dries in a few minutes. There are no pools of water that require additional drying effort.

Doesn't your robot miss parts of the floor during the drying stage? I pick up chairs but I cannot remove furniture like tables, cabinets etc. My robot often leaves puddle around the table legs and along the cabinets and walls.

I suspect that there is something else wrong with your 450. I certainly do not get puddles of water left on the floor when the 450 cleans the floor. And yes the 450 does not go back over every portion of the floor while cleaning so there are areas that may not be recovered but no puddles.

vic7767,
Are you using the new Li-Ion battery to run your Scooba 450?
If yes, your 450 may run a bit longer and does a better job.

I don't have a 450. I am just guessing
Charging battery directly: 400 Series, 500 Series,. How to Desolder
