I bought up a bunch of robot vacuums from Dreame, Ecovacs, and Roborock lately to test them out and they were all really bad at vacuuming so I returned them to Amazon and bought a pair of used Roomba j9+’s the non mopping combo ones and they vacuum so much better than any of the new combo vacuums did and saved me tons of money

Have a j9+ and that thing is a workhorse that rarely has issues that interfere with the schedule. The issue is roomba has no competitors that aren’t liable for the same fate (eventual etrash)

Also not happy with the j9+. So much promise, so much work to make it take care of things for you. I tell people it won't save labor or just shifts it. Determine if you are happier troubleshooting or vacuuming. Time spent in either is about the same.

I think skipping the mop is the way to go. No loss in suction power that way. I have the J9+ and would say that the self emptying is meh for me. I like to tap the filter clean after each use, so I almost always empty her myself. The only time it has come in handy is when she thinks she is full due to debris (leaves).

Get the straight vacuum. No combo because you lose suction. I had a 985 that is still running but was relocated to my son’s campus housing. That thing was not smart, but did an outstanding job. I have a J9 now. I feel like it does the job more efficiently, but is not quite as powerful. I still love it for cleaning up after my cat and dog though.

I am on year 1 of 3 with my j9+ robot. Needs to be cleaned a lot to keep it running but it seems to still do a good job. Hope the company can keep mine going till the contract expires. I like my Mr Jarvis! :-)

Whoa man, firstly huge thanks for your job here, with the comparision. After very bad issues with Roomba Combo J9+ (returned to seller after four months ) i need to buy a new robot. And sorry, even new 505 looks nice i don't want next iRobot. My flat is 70 sq. m., 90% hard floors, 4 rooms, bathroom, toilet, no animals but me and wife have a longer hair :). Moping is important, battery not, good self cleaning yes. I like the specification new Dreame L40s Pro Ultra and also consider Mova P50 Pro Ultra which one is 100Euros cheaper and is avalaible from Amazon and they have a good return policy in case of troubles. What do you think, it it a good choice? Should i look closer to any other robot?

I can’t blame you. When the Max 10 or Combo j9+ work as they should,…….they are really great products. I run two Combo j9’s and a plain j9+……in a 1700 square foot rancher. I’m OCD. Love em. Love em.

For the love of everything good, don’t buy a Romba. Our j9 with a cleaning base is terrible. The hardware is okay, but the software is garbage.

Mine often forgets that it has a clean base, stating that I need to empty the dust bin in the robot. Why, use the clean base. Also, why can’t I always make the clean base empty the robot? The button only appears at random. The robot also exists the clean base by making a sharp turn, driving off the edge of the base. Very clumsy. It often can’t enter the clean base when returning. It keeps trying to adjust its trajectory, back and forth, blinking with the camera blitz to determine how to enter the base. Again, clumsy. And we haven’t even started talking about it being confused about its location.
