Love Roomba mop and vacuum

[This review was collected as part of a promotion.] We already have a Roomba with vacuum base dock that we love using, so we were excited to try the vacuum/mop combo. Having an automated vacuum really helps throughout the week between regular vacuuming to keep the dog hair from our 3 dogs from collecting as much. I didn’t like that I had to get a whole new app for this version and that the new app can’t control my older one even though it recognizes it through Wi-Fi. I thought it would have a separate tank for the water on the actual vacuum, but it wets the pads from the tank at the base and periodically goes back to re-wet. I like that I can set how often it goes back. I was wary as to how well it would mop, but the dirty water tank shows it’s doing a good job. Again, just using between hands-on moping sessions it’s nice to maintain a clean feeling floor more regularly. I have had some issues however. When first setting up I tried placing it next to the old Roomba but found out through support that it really does need to be placed away from other units and a few feet away from surrounding walls and objects. So, that decommissioned our old one as we don’t have much floor space or plugs to keep multiple bases. Also, the first time I used it there was a puddle of water forming at the base, thankfully that seems to have resolved and may have just been where it was the first time being used. Once it makes a map of your house you can designate areas as cleaning zones. However differentiating them doesn’t seem to affect the cleaning cycles. For instance, you still have to select how you want each room cleaned. Whether it’s vacuum only, mop only, vacuum then mop, or vacuum AND mop. So even though during setup I selected the rooms without carpet that I would want it to usually mop, I still have to go in and change the cleaning type for rooms with carpet because it defaults to vacuum and mop. I wish I didn’t have to do this EVERY time and that the mop mode would stay dedicated to the proper rooms. I also observed it only vacuum, return to the dock and not start the mop cycle when I had selected different tasks for different rooms, as if it couldn’t handle all the different information. My older roomba would return to the dock every now and then to empty, but this one doesn’t seem to do that until the end. Which is crazy because I have to empty my upright vacuum several times from all the dog hair. It doesn’t even empty when returning from vacuum to wet the pads before mopping. It will build up the dog hair under the rubber roller and form a little log of hair that it leaves around sometimes. When it forms I noticed it starts making a loud clacking noise. I also had to pull a wad of hair out of the back flap where it had gotten so full and couldn’t suction it out at the base. I think this issue could be solved if it would just empty more frequently. Over all, I will continue to use but these little issues, besides regular maintenance and cleaning of brushes, add up and defeat the purpose of an automated vacuum.

Life changing!

[This review was collected as part of a promotion.] This is my first robot vacuum/mop combo. If you thought your robot vacuum was life changing, think again! For those with pups, you will never have to look at paw prints on your floor again! It was a breeze to set up and the new app is great. It mapped the house accurately and I like how I can choose to clean certain rooms if I don’t need an entire clean. Go buy it now!

Good cleaning performance, but leaves the floor a

[This review was collected as part of a promotion.] Setup was super quick—just 5 minutes to unbox and connect the robot to the app. Adding it to the app was also easy and smooth. Performance-wise, the robot cleans well, and the hardware feels solid. The vacuuming and mopping are effective, and it’s great that it empties its dustbin and washes the mop pads after each session. The water tank lasts about two days, and the hot air drying feature is a nice touch. One thing to note: compared to my other robot (from a different brand), the Roomba leaves the floor a bit wetter after mopping, so the drying time takes longer. You can set up no-mop and keep-out zones, but there are some downsides. Keep-out zones can't be rotated to match your furniture layout, and there’s no virtual wall feature to create custom-shaped boundaries. Also, you can't set a no-go zone too close to the dock. Spot cleaning works, but you can’t adjust the size of the area. Another thing missing is a button on the dock—you have to use the app or press the robot itself to start a clean. Unfortunately, the app froze twice on the first day, and it doesn’t show any dock status info, which would’ve been useful. Mapping is slower compared to other competitor, but extra mop pads are included, which is a plus.

Decent for Daily Maintenance

[This review was collected as part of a promotion.] Easy to assemble. I have an older, non- mopping version. I was disappointed in how loud this one is. It also doesn’t pick up dirt as well as my old one. The mopping is nice but since it leaves a touch of dirt, even on the highest suction, I feel like the mopping just moves around the debris. Good for maintenance but not for deep cleaning. Appears to be quite durable and battery is great unless you have the mop turned on, then it returns often to charge.

Amazing combo for your floors!

[This review was collected as part of a promotion.] This truly is an all-in-one product! The mop and vacuum combo work seamlessly together, leaving my floors clean and spotless. I use the app, so I'm able to select which areas I'd like the Roomba to clean, making it easy and efficient. Its self-cleaning feature is great as well.

Very Useful cleaning tool

[This review was collected as part of a promotion.] This is my first experience with a robot vacuum. The set up was simple and after mapping was complete it was easy to set up my rooms and borders to be able to switch them between vacuum or vacuum and mop. I love the ability to have it double clean or vacuum then mop. This is a huge help around the house and makes my life easier. I can’t rely on this to clean everything perfect but it does a really decent job at 80-85%. It has a tricky time with corners and objects, so I just move everything out of the way when I have that room being cleaned (like kitchen table chairs, trash bin, etc. The mop could be a little better but again, does a decent job without me needing to do anything. I’d recommend with the understanding it’s not going to be the only cleaning, but will make your life a lot easier!

Mopping made easy once roomba is set up

[This review was collected as part of a promotion.] Overall, I am very pleased with this mop/vacuum combo. I did have some initial frustration, but once I figured things out, the results were great. First of all, it is easy to unbox and set up. It is quite a bit larger than the regular roomba that empties its own bin, so you will need space. I needed a different app, and the roomba got stuck on updating. I had to reset and start over to get past this. The first thing the roomba does is map the space. The majority of my area is vinyl plank but I wanted to keep it out of the carpeted living room. I should have let it map everything instead of focusing on keeping it off of the carpet when mapping. You can adjust the map in the app later. The second frustration was the map. It wasn’t entirely accurate and i couldn’t split a room. I was still able to make it work and place keep out and no mop zones. Finally, you do need to pick up any rugs. Once that was all set, the roomba swept and mopped the whole hard surface of my first floor. The floors looked good and I didn’t have to do anything. It did go back to the dock multiple times to clean the pads and get water but it went right back to the spot it was at to keep cleaning. Overall, very impressed with this roomba and glad to have the ability to mop without having to do it myself!

Absolutely love the maintenance for cleaning floor

[This review was collected as part of a promotion.] Where do I even begin? I absolutely love this thing! We have two other roombas - one just does carpet and the other vacuums and mops, but it doesn’t have a refilling station and holy buckets is that a game changer! We set this on a schedule to vacuum and mop MWF, which would never happen previously, so it’s amazing to come downstairs at lunch and your floors have been cleaned almost by themselves. It also dries off the pads, so you don’t have to worry they will get mildew. Downside is that it’s more of a maintenance thing, so it’s not going to get any really grubby floors - so you’ll want to do a heavy duty cleaning before, but again I’m not mopping three days a week so this is amazing.

WOAHHH

[This review was collected as part of a promotion.] All I can say is WOW. This thing is absolutely amazing. From the packaging to the technology it uses this rooms is state of the art. It maps out your whole house and cleans while you’re away. It’s cute and quiet and I named mine wall-e! With three kids, one being disabled, I don’t get to vacuum or mop as often as I’d like. So this product has been an answered prayer! ⭐️
