Best Vacuum Purchase

This vacuum/mop has really been a lifesaver. We have kids and a dog and it really helps to have something that can be programmed and it runs. This not only keeps our house clean but saves us time. It navigates our floorpan well and handles different terrain.

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.

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!

Quiet compact vacuum .

[This review was collected as part of a promotion.] iRobot Roomba plus 450 combo robot is definitely an upgrade for me who has always used a traditional vacuum. Remote operation and control via app in the mobile device makes it easy and convenient to operate. The iRobot recognizes the obstacles and along follows the map efficiently. The clean power and suction is great the rotating brush get to the corner and unreachable areas easily. It automatically goes to the dock to charge. The mopping function is great and cleans well . It automatically empties as it gets full. Definitely a great vacuum that operates quietly ,great for office or big room with minimum obstacles that doesn’t require moving to clean and mop.

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.

All in one carpet and floor cleaner

[This review was collected as part of a promotion.] I am so glad that I got this Roomba iRobot. This is a multi use vacuum. Mops my hardwood floors and vacuums rooms with carpet. Super easy to install pieces together. It's not as bulky as I thought it'd be. Fits perfectly in any corner of a room. Keep in mind you will have to download the Roomba home app so you can program the device to your home. You can go as far as to program the machine to not go in some area you may not want to be cleaned by the device. There is a bag that holds plenty of days worth of debris. The water container has one side for clean water and the other for dirty water. I love this hands free vacuum. It is on the high price of vacuums/mops but it is so worth it. I was so tired of ringing mops and renting carpet cleaners. This is an amazing device.

Roomba plus 405

[This review was collected as part of a promotion.] Overall I find this Roomba plus just okay. The set up was pretty easy including the attachments on the bottom. The first run it leaked a bit but the second I had no issue. As with roombas this is all set up with in the app and will map out ur floor plan. It does well with navigation but I think a more open concept home would be better with this. Also may not be best for homes with pets. I have three dogs and it just isn’t made for that. Also when cleaning corner and along the wall aren’t able to be done so it’s more for just a daily maintenance than thorough cleaning. Suction is fine and goes over low pile rugs easily. This product could be fine for the right consumer but no everyone. I

A fluke??

I really want to love this but I need to return it. I love the vacuum and mopping. Much better than my previous vacuum. However, I need to return as the battery is not staying connected and it won't run. I already contacted Roomba customer service once and they showed me how to fix it but it happened again and now it won't start at all. I'm going to purchase another one thinking that this initial one was a lemon and the new one will be better.

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.
