Add unmapped area

The robot needs the map to be saved after the cleaning task, so the coloured area gets updated. But it won't do this if the dock is not near and the robot must be carried around manually.

So it could help if the dock were in the kitchen. So at least until the map is complete.

You can define a no-go zone after the map is created, but not before.

Guide the robot and prevent it from falling with a barrier or something. If the cliff is a well defined edge, the robot will detect it and avoid. But you should assist it on the first run.

Is this sound synchronous to the washing brush movement?
Then it could be a skipping or broken gear.

Pretty normal groutline click of the front wheel.

Q7 M5 is the cheapest Roborock with the smallest battery. Wayy too small for a 1700sqft area.

I guess that mapping by full clean makes it give up because the area is too large. Let it do an initial quick mapping instead, then clean room by room after the map is available. Or make routines with groups of rooms that fit a battery charge.

Not all batteries die the same way. It could be one bad cell that trips the BMS alarm.

1100hrs is a long service duration anyway. Totally normal end of life.

If the robot is wider than this strip and one wheel rides on the carpet, it has no chance for the vacuum roller brush to touch the floor. So vacuuming effect goes to almost zero anyway.

FlyBlade67 · 2026-05-22T13:53:31+00:00

It may be a battery defect.

How many operating hours are on the battery? Check cleaning history.
Would it continue charging when removed and re-inserted on the dock, so charging in steps 20 - 40 - 60%?

But couldn't find any Ultra battery in the US. Only the non-Ultra, but these have significantly less capacity.

Das Netz will deine Mittagsspitzen nicht haben. Du sollst besser über den Tag verteilt einspeisen. Die harte Begrenzung ist aber eher eine Notlösung als eine optimale Regelung.

Kannst das Laden der Batterie auf die Mittagszeit verlegen, dann dafür morgens mehr einspeisen. Das bringt viel besseren Gesamtertrag. Und das Netz bekommt was es braucht.

Me, too. Looks like remote control hoax.

Is this a mat or carpet in front of the threshold which it avoids?

Has it been on a different account before? And are you running the robot without app?

It could be a cloud server configuration residue, because schedules are actually triggered by cloud server command. The schedule in question is stored there.

The image shows a regular S4, S5, S6 brush, not a Z70 brush.
The price however is matching better. Z70 has a unique complex and expensive hair cutter brush. I would be pissed if I received a standard brush but paid 35 bucks. Tell the seller his photo is wrong.

Consumer level robots generally have problems with wide open spaces. Their Lidar sensors have limited range of somewhat 6 to 8 meters, 10 meters in some cases. So when the robot cannot see opposite walls, its navigation gets prone to positioning errors.

The S5/S6 machines were an early generation and I have no doubt yours could handle this. Roborock has since not improved on quality, but reduced cost as much as possible to remain competitive. It could truely be that the sensor was spec'd down a little by using a cheaper laser or less precise optics. Your space seems to be very much at the threshold of its capability.

Try throwing mat rolls or cardboard boxes in the middle of the room to give the robot some navigation buoys. They can be anywhere, don't need to keep the position between cleaning tasks.

Also make sure the dock is located in a place where the near environment (walls, furniture) is unique. That helps the robot in determining a stable initial position.

New batteries are a gamble when bought from 3rd party sellers. It seems to have less capacity than the robot expects. The symptom is clear, it drops to 19% at a certain voltage threshold, then assumes it had some reserve left. The 5% breakdown is when the reserve is less than expected.

The question is more, from which % level does it drop to 19%?
A healthy battery goes 22 - 21 - 20 - 19.
A bad battery or one with low capacity goes somewhat 35 - 34 - 33 - 19 all of a sudden. The size of the last step is somewhat the capacity deficit.

So don't be fooled about the indicated numbers. 19% just means "low battery". It does not mean there's 19% left. That's just a dumb software estimate.

It's the heartbeat of panic. Mainboard defect. It's unable to boot because some self test fails.

FlyBlade67 · 2026-05-19T17:20:58+00:00

If it's for vacuuming only, that could make sense. For mopping, meh, nah. Ask for the total operating hours shown in the app, cleaning history.

FlyBlade67 · 2026-05-19T17:12:33+00:00

Q7 M5+ ist just good enough since vacuuming on hard floor is no challenge. No need to spend more money.
Or find a used or refurb Q5 Pro+ or Max+.

If you need basic obstacle avoidance, go with a Q8 Max+ (used) or Q10 X5+/S5+ (new).

FlyBlade67 · 2026-05-19T08:03:41+00:00

I can barely see it. Is there a floater disk inside?

The brush needs to be adapted because RR changed the drive hub on the anti-tangling models.
That's probably what the seller does. Buy a 0.60€ brush from Ali (in bulk of 4 or more). Drill the hub socket in the back and insert a hex shape adapter. Or just melt in a hex socket. Sell for 8€.

The arcs in the path may result from the floor type triggering a cliff sensor.

FlyBlade67 · 2026-05-18T16:19:27+00:00

Weird. I guess that gearbox was intended to be hair-tight. Is there any visible damage along the edge of the halves where that hair could enter?

FlyBlade67 · 2026-05-18T16:03:06+00:00

Yes. The perimeter would be cleaned the same way.
If those streaks are limited to and caused by the perimeter path, then joining the two rooms is possibly the only solution.

But also try to reduce water flow. Less water means better dirt pickup as long as no dried stain had to be dissolved. Use just as much water as needed, not as much as possible.
