My Life Just Got Easier With Roomba

I have neck and spine injuries, I am a bit OCD and love a clean house, I used to vacuum every day, but now vacuuming puts me down for three days. The iRobot Roomba 4020 Combo was the absolute best purchase that I've made in a long time. My home is vacuumed, mopped and looks amazingI! It took me parts of two days to set up the 4020 with no zones and splitting of rooms but, it was so worth the time! Be patient, take your time and you will be glad that you did! Oh and don't forget to order the appropriate floor cleaner, also I have well water so, if you have a well, I would recommend adding distilled water to the reservoir just to be safe of scale buildup. Thank you, Roomba for making my life so much easier in saving me from the physical pain of vacuuming and mopping.

Great Mop/Vacuum Huge Upgrade

[This review was collected as part of a promotion.] This Roomba is far superior to my other Roomba. I have used the mop and vacuum feature on my tile floor. The time is about 1000sqft and it did a great job. When filling up the water tank for the first time I thought this amount of water will only make it through one clean but it barely made a dent in the water reservoir. My previous rumba would bang into walls and furniture but this new one will sense the items and avoid them. My favorite feature on the app is the spot clean. I have two little children that are always making messes and to have this spot. Lean ability is a lifesaver. Overall I would recommend this to anyone.

Grateful for our daily upkeep

[This review was collected as part of a promotion.] If you have animals like me , especially heavy shedding kinds read on to get my take on owning the Roomba plus 400 serious. I have 2 cats, one husky and a Pomsky, so lots of shedding, the Roomba is amazing for maintenance, but it's not going to fully replace a regular vacuum with that level of shedding. Think of it as keeping things under control between your deep cleans. The Roomba is extremely convenient when I'm busy or just don't feel like doing it that day, I can go in the app on my phone even when I'm not home and select from 3 different levels of vacuuming or chose the mop and vacuum option. I always select deep clean because of the amount of animals I have which is really nice because I am often busy. It takes the Roomba about an hour and a half to do a deep clean for my living room and kitchen. The mopping function leaves the floor a little bit wetter than I would like for LVP floors, so when I use that setting, I have to be prepared to go behind with a dry mop to just kind of dry the floor a bit. I do really like that. The Roomba has a self cleaning function so when it's full, it empties into its own vacuum bag. And it also cleans out the water tank and refresh's it so you don't get any icky water just sitting stagnant. It has a smart feature where it maps out your house and you can designate areas you don't want done. A problem I have with the mopping function is it did try to mop my carpets even though I marked that section as a no go. I wish I could say the Roomba wasn't that loud, but it is pretty loud & The Roomba docking station is rather large and is an eyesore, so I don't love that but the convenience of it outweighs the con's lol. Overall, I would give the Roomba four stars out of five.

Best robot vacuum

[This review was collected as part of a promotion.] This has to be the coolest gadget in my home. It will always blow my mind how this robot vacuum/mop knows how to map out your home so it doesn't crash into walls or anything. My floors looks and feel clean at all times. It fits nicely in its own little spot in the living room and it's easy to assemble. Awesome product!

Junk

I have had this thing for just over a year and it's never worked right. I've called the manufacturer reset multiple times remapped and it's never went back to its docking station properly, for a few month I was able just to run it as a vacuum cleaner, but then it stopped doing that. I've had other robot, vacuum, cleaners, and had no problem with them the last one last me a few years.

Best roomba I’ve used yet !

[This review was collected as part of a promotion.] I have been loving this roomba. It does a surprisingly good job of cleaning the floors with the mop. I love that I can set it to deep clean or just light wash where it’ll go over more times. You can also vacuum separate from the mop which is even nicer. The suction has been great. It’s very efficient time wise. So far no complaints.

Cool gadget but not a need

[This review was collected as part of a promotion.] Easy to set up. The sensors on the machine scan the room to set up where it needs to clean. The looking function works really well and even avoids carpets or rugs. The vacuum works but not the best.

Exceptional cleaner

[This review was collected as part of a promotion.] The Roomba Plus 405 Combo robot and AutoWash with dock is an amazing house cleaning tool. It didn’t come with a quick start guide. Since there was no QR code to scan, it was much harder to get it set up. I couldn’t get the robot to sync with my app. It took me 45 minutes to get it set up to go. Once it was synced and ready to go, the robot mapped out the floor it was on in about 90 minutes. Once it did that, I had it clean 3 rooms. It stopped a couple times to clean the mop heads and once to empty the vacuum compartment. I used plain water to clean the hardwood floors. It picked up all the crumbs in the kitchen and did a nice job mopping in neat rows. In the foyer, it mopped away footprints from someone’s dirty shoe. The vacuuming was effective—it picked up a lot of cat fur and crumbs. It didn’t get stuck in cords that I couldn’t hide. It is quiet enough that I was able to watch TV still while worked. I took a video of it cleaning, but it won’t load to this review. I like that you can edit the map to label the rooms. You can also go into the map and subdivide a room for shorter cleaning sessions. For instance, if I cooked a lot and made a mess in the kitchen, I can have the robot only clean the kitchen—not the entire first floor. Overall, this is an excellent product.

First roomba

[This review was collected as part of a promotion.] Never have tried a Roomba before, and so far I am impressed. Initial charge from opening the box wasnt too long, along with the first "mapping." I haventt used the mop feature yet just the dry vacuum, which I am impressed with. Noise level isnt too bad either.
