The mopping performance of their current bots (505 Combo and 705 Combo) is actually very good, arguably the best on the market due to the Y pattern movement

Push for the 505. Although it does have lidar, the 405 does not have the obstacle avoidance tech of the J9. The 505 does.

Personally, I would only consider the 505 mop combo at this time. At $599 currently, it’s discounted but I wouldn’t say extraordinarily so. The 405 mop combo is similar to the 505 and has a much better discount at $399. For me, though, the lack of obstacle avoidance in the 405 is a deal-killer. The 505 also has heated drying of the mop pads and can swing one of the mop pads out to reach corners, something the 405 also lacks. Not as big of a deal to me as the lack of object avoidance in the 405.

I got the 505 its just as you say too wet at first and I'm worried about my floor

I would recommend a roomba model that detects stuff, from a J7, J7+ to a J9, J9+ (the do detect pet "presents"😅) not the J9+combo, (that units dock had plenty of failures) I would also go for a Plus 505 combo if you also want to mop the floor, because It has the laser view but also a front camera. J7 J9 send pictures of obstacles and asks you if they're permanent or not, you could ask an AI to compare those models to better pick what suits you best, hope I've been helpful.

I started using the Roomba 505 Combo in June, and here are my thoughts (I didn't receive any payment). My home features marble tiles and wood flooring as the main materials. I can honestly say that this robot vacuum is absolutely perfect for families with hard floors. 1.Overall, I would rate the vacuuming performance as excellent. I can't guarantee excellent carpet cleaning, as carpets are the domain of the 705, but the 505 definitely scores 90 out of 100 for vacuuming hard floors. https://preview.redd.it/n3bmukoeum0g1.jpg?width=1280&format=pjpg&auto=webp&s=deac078876c9b342bcbd63b3e9ff193d2aca88cd 2.Regarding mopping, I felt it was too wet at the beginning (which might not be suitable for some wooden floors), and too dry towards the end. However, the SmartScrub function did significantly improve the cleanliness of the mopping. Overall, I would rate it 65 out of 100. 3.I'd give it a 95 out of 100 for obstacle avoidance and navigation; it basically doesn't miss any obstacles, but the app can't view obstacle images. This time, ClearView Pro LiDAR also recognizes furniture and adds it to the map, a significant improvement over the previous generation. https://preview.redd.it/duqivb1nyr2g1.jpg?width=2355&format=pjpg&auto=webp&s=fdd7188a048d00e7669d5a0d71856b44bd01479e 4.The AutoWash base station function and dust collection are excellent. I've examined the dust collection box; it has one hole for air intake and another for exhaust (dust removal), resulting in very clean dust. The cloth washing function is a bit weak; it uses two scrapers, and after adding water, the mop rotates on top, but only uses room temperature water. The cloth drying function works perfectly at 45 degrees Celsius. I give it 80 out of 100. https://preview.redd.it/wxc44i6yum0g1.jpg?width=1331&format=pjpg&auto=webp&s=4062050005d1936fa4b84c38b11250746b19be53 5.The anti-tangling features between the main brush and side brushes aren't very good. Occasionally, strands of hair get tangled in the main brush, while the side brushes get quite a bit tangled. I'd give this a score of 60 out of 100. 6.The Perfectedge® mop head with its excellent corner cleaning function is great, but it's a pity the side brushes don't have an extension function. Overall, I'd give it an 80 out of 100, because it's much better than my old Roomba 530 7.I think the app design could be improved, but after getting used to it, you'll find many thoughtful little details in the app. The customized swipe function is great, and the new map is also well done. I give it 70 out of 100. https://preview.redd.it/mtigatb5ym0g1.jpg?width=1080&format=pjpg&auto=webp&s=594dd29b74b654b1de0a89ebad1b2ccd7d5af8b1 Taiwan

I just read your comment. I've also isolated my Roomba Combo 505 robot vacuum cleaner through a D-Link router to ensure the security of other smart home devices. I also have D-Link cameras connected to the internet, and I'm worried that China might use them to attack my smart home system.

Indeed, I'm not afraid at all that he'll publish my home map; my only concern is image security. I'll check out other brands of lensless models. Thanks! It's too late. I bought a 505 Combo in June and can't return it now. I'm thinking about what to do next. I won't throw it away, but I need to take some safety precautions. And I definitely won't choose their products for my next robot vacuum.

Wow, that's awesome! I've already added Shark to my consideration list, although I've seen some criticisms. Could I see what the app looks like? My iRobot Roomba Combo 505, which I bought in June, still has a terrible app. Anyway, I definitely won't be buying another iRobot.

I’ve had the newest Roomba505 auto empty, auto wash, vacuum and mop combo for a couple of months now and I freaking love it. I got an email this morning they’re trying to suck me into buying another with a big sale right now... $599 for that one I think? I paid more a couple of months ago but it’s been totally worth it. It deals with the dog hair (I’ve got two sheps) better than the older roombas and so far hasn’t gotten tangles around the brush or the mop heads.

My mom didn’t like the s9+ I gifted her, long story. I got her the Roomba 505 and she loves it!! The switch to LiDAR was a huge improvement.

I have the 505 combo and it avoids things very well and snakes through chair legs etc much better than I thought it would. Not sure what the 705 upcharge is for
