iRobot Roomba S9 vs Roborock S5 Max

I’m currently trial running several auto-empty vacs for our upstairs which has our 4 bedrooms and all carpet. Currently a few weeks into the Roomba S9+ with empty bin and let me just say… while it does a good job picking up on our low rise carpet, the app and technology feels about 5 years behind the Roborock tech and app. If anyone cares about specifics feel free to ask but I’m constantly surprised how poor the app and tech work. Ghost rooms, connection failures, inaccurate post run results… considering how long iRobot has been in the game I’m just really surprised it’s this far behind

The short version; This is a terrific vacuum. My floors have never been cleaner. I am very satisfied with my purchase and could confidently recommend it. I really feel bad for giving it only 3 stars, however, a few minor issues detract from making it the perfect product

I was worried that the new D shape would make it a little more cumbersome for fitting around chairs and table legs. But if you look at it, the Roomba ...

The older mops were basically small capacity tanks with a pad that just attached to the bottom of the robot. They functioned essentially using gravity...

This robot vacuum has improved in many areas. Great suction, flawless operation (most of the time), and wonderful battery longevity. Sadly, it has regressed in others. Namely, the filtration system; why have they decided to sacrifice the pre-filter mesh and opt for more frequent cleaning and ultimately filter replacements

My main purpose is to keep The house free of dust and pet hair, And it Meets my expectations.

Even though the area was completely clear. The problem is due to the lower clearance from the upgraded suction unit, the edge brush get's deformed and smacks the bumper and screws up the sensors. One could probably modify the brush, but I didn't want to deal with it. iRobot says the s9 has 4x the suction of other Roombas, I don't doubt this

So here is my issue... I think this is a great vacuum if you have absolutely zero thresholds

**Roomba S9+:** More powerful but didn’t feel worth it for the price. Didn’t have a lidar. 1099$.

It was just programmed differently in terms of its power usage. In any case, the point is that these 150 minute plus numbers are really good, like it'...

If I try to mechanically / physically raise the spring contacts, I risk breaking them and making it all the worse. Those should be able and EASY to replace, without needing to disassemble the whole vacuum.

It has been reliable and easy to use. - It does a great job of mapping the house and generally runs in a logical way. - One of my favorite parts is that this is a modular design and can EASILY be repaired by anybody of any skill level. For an expensive investment, this was important to me knowing that I can keep it running for years into the future

I don’t recall the error code but it was common with many S9+ that were released around Christmas 2020 but whatever it was, when that error struck, your Roomba was dead. You’d expect better from a $1K machine. Whatever the case, in the 2 days it worked, it was ridiculously loud compared to the s7, was the rudest little bugger ever (pushing chairs out of the way, knocking things over), and it did a half-ass job cleaning things.

Yeedi is so quiet, the roborock is rather loud. If yeedi added multi-floor mapping to their app, I would switch back in a second! Roborock is a good vacuum, for when your not home, but if your home it's loud and annoying.

For the price it is a HUGE waste of money. Do your self a favor and buy a cheaper one. Hopefully the quality hasn't gone down on them.

A week or so ago it received another firmware update. Great value for the price paid.

I used to be able to vacuum off the filter more easily because the dirt was not all wedged into the folds of the filter. The new Roomba filter does not have this mesh, so it's going to need to be replaced more frequently. I am hoping that they decide to add the mesh to this filter in the future.

I’ve had this vacuum a little over a month. The filter is at an estimated 49% life left, side brush 62%, and main brush 75%. For perspective, I use this for a ~1200sq ft area with tile and vinyl plank floors. It gets stuck on small rugs sometimes, been meaning to get some carpet tape

The Roomba 960 does that just fine, as does the RoboRock S6 Pure (which I also got after returning this). So IMO there is no legitimate excuse for this fundamentally flawed mechanical design of the Roomba S9.

I would give it 5 stars if there were a better solution for the sensors, like designing the sensor area to accept a clip on block that does what the tape does but is more permanent. The tape works well but is still wonky.

I like the fact that I can program when and where it cleans. The only thing I don't like is cleaning the filter as the dust flies everywhere when it is tapped against the waste receptacle.

The filter is washable, but we found with the e4 it takes forever to dry. The solution to this is just buying a second filter and swapping them when one needs to be cleaned. Easy peasy. The map function works great, dividing/separating rooms is easy
