iRobot Roomba S9 vs Roborock S7 MAXV

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

However, in both cases, only a small amount of dirt remained on the pads. You eventually need to wash the pads by hand or in the washing machine, but far less frequently than you would with a traditional robot mop.

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 ...

* First, run the bot on vacuum only on the highest setting (clean the bin and filter after)

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

The S7 MaxV packs 5100pa of suction power, close to double that of the S7. It has a 400 ml dust bin and a 200 ml water tank (smaller than the S7), but if you get it with the Empty Wash Fill dock, those sizes don’t matter as much. A 5,200mAh battery delivers around three hours of runtime, depending on which settings you use, and it will take about six hours to charge up fully.

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

Edit: Roomba-level performance meaning purely in situations there is a carpet involved, and only in regards to how well it deep cleans, disregarding pretty much every other aspect of the robot.

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.

- Setup was *super* easy! A few clicks on an app and inserting wifi password - BOOM. DONE.

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.

Super excited to grab the S7 MaxV, but trying to get the best price point given its steep tag.
