| Last year I did a lot of research on Reddit and other sites and finally settled on the Roborock S7 Pro Ultra. Some learnings I had along the way: - Software quality is crucial, and new models are often iffy. Badly programmed vacuums (and almost every brand has those) are incredibly annoying, because they get stuck constantly, fall down stairs, leave dirty areas, can’t find the way to the base station, etc. Roborock seems to be one of the few who nails this. - Suction power should be maximized, or you’ll spend time cleaning up after the robot. The S7 I bought has 5100Pa and I think that’s acceptable, but I still need to do two runs sometimes (which is low effort for me, but it means more noise). - Since we wanted a vacuum that also mops: Those mops, if not managed well, get moldy and start to stink after just a few days. Build layout and engineering quality are big factors here - ours almost never stinks even though it has no drying fan (some do). - A base station is needed for real hands-off usage, and those are damn expensive when bought afterwards. And do change the water tanks regularly, they can get quite smelly, fast. It’s the one non-negotiable maintenance we have to do every week. - I was looking for vacuums with explicit mention of HEPA filters, but it seems the more expensive ones have decent filters without ever mentioning HEPA. I’m still not sure what grade the S7 filters really are, but it seems allergy friendly (likely also owed to the mop and the usage of a filter bag in the base station). - Even if the manual says to wash the filter, don’t; they will often degrade. Better to use compressed air (carefully) to clean instead. Overall, we are still happy with the S7 Pro Ultra after a solid year of usage. It’s been a time saver rather than a time sink, and apart from getting stuck sometimes laying around, it has always done a solid job. |
Few things:
1. We have HEPA bags - each bag acts as HEPA filter.
2. We found that more than suction power, the brush roll is more import for effective sweeping and vacuuming. It picks the dirt way better… so we have designed first of its kind to hair tangle-free brush roll. It is designed to be effective on all kids of surfaces.
3. We further improve efficacy with actuating cleaning head so it adjust the height for each type of surface with diff thicknesses.
4. The HEPA bags last a month if just vacuuming and about a week if daily vacuuming and mopping. It collects both wet and dry messes. It even has version of diaper salt and charcoal powder so it doesn’t smell or get moldy.
5. But the most important is completely Vision first perception with precision 3D system so that it doesn’t get stuck, chew wires, etc.
Indoor world is entirely built by humans, for humans, to fit our vision first perception system. So we have given it a very similar perception system.
6. Private by design. It was built to work completely w/o internet connection.
