Narwal Freo Z10: Clean Water Tank Empty ... but it's NOT

Sun, 12 Apr 2026 07:59:47 -0700

We've had our Narwal Freo Z10 Ultra for about 6 months now. Love this thing! However, we seem to be having a recurring issue with the base station clean water tank. After filling the clean water tank and starting up, the narwal becomes angry from time to time and will say "fill clean water"... even though the tank is full and properly installed. My wife has found a temporary fix: using a baby medicine syringe to inject water into the base station clean water tank connection point. Doing this 3 or 4 times seems to clear up the issue... but a few days later same fault occurs. Anyone know of a root cause or complete fix?

Some things I have tried:

Cleaned both waste water and clean water tank thoroughly

Small pipe cleaner run through of all water lines to verify no obstructions

Thorough cleaning and maintenance of vacuum robot

This close to tearing the base station apart and doing a thorough cleaning.... when the wife isn't looking🫣

Samsung Jet Bot VR30T80313W: Battery won't charge.

Mon, 23 Mar 2026 07:41:37 -0700

So I just got my robot vacuum back after lending it to my brother.

Turned out it stopped working a while ago.

When I got it back I started to diagnose it.

The first thing I noticed was, when it's docked in the charginstation, it turns on and I can adopt it into the smart things app. The battery read 0% and no matter how long it charges it wouldn't go up.

So I started by disassembling the battery down to its individual cells. Turned out 5 out if 6 cells were completely dead (absolute 0 volts).

So I ordered some new cells and put the battery back together. The battery now shows 21,7 volts. But it still doesn't want to run outside the chargingstation.

When I use a multimeter on the battery, while it's connected to the chargingstation it shows about 25 volts on d+ to d- (the plugs from the vacuum to the PCB on the battery). And still 21,7 volts on b+ to b- (the spot welded tin to the battery). It has now charged for about 2 hours and it's still about 37% charged (so not getting charged).

I've tried to put the PCB under an thermal camera to see if anything gets hot, but it doesn't. Even with it plugged into the chargingstation, without the chargingstation or it disconnected from the robot. I've also tried to connect 21 volts 1 a with a powersupply connected both on d+ to d- and on b+ to b-, yet nothing gets hot.

Anyone have any idea on how I could fix this?

I'm pretty new to this stuff, but I do watch some youtubers like NorthridgeFix and TronicFix so I have some general idea.

Should I disconnect the cells again and maybe try injecting voltage over some of the chips on the PCB or check the resistance on some of the caps? If so i would love some guidence. I don't have a chip programmer yet, but I will order one sooner or later, if needed.

Roborock Qrevo S: roborock Qrevo S Robot Lidar error. Check that the turret turns freely

Sun, 15 Mar 2026 19:28:47 -0700

Does anyone have a guide on how to disassemble the Qrevo S?

Context:

My robot hasn't hit the year mark and yet he doth betray me with the Lidar error. I tried spinning the lidar with a cotton swab a few (15) times (it turns just fine), cleaning the area with a toothpick and vacuum, moving it, soft resetting it, hard resetting it and now I'm at a loss.

I followed this guide initially, but unfortunately it doesn't get me all the way to the turret motor in my model: https://www.reddit.com/r/Roborock/commen...

I have tried YouTube, google and am a hair's breadth away setting fire to my poor tool kit.

Any help or advice would be really appreciated.

eufy RoboVac G10HYBRID: How to fix a Eufy RoboVac G10 Hybrid that won’t charge and reports low

Sat, 14 Mar 2026 05:33:24 -0700

How can I fix a Eufy RoboVac G10 Hybrid that stopped charging suddenly?

The vacuum was working normally, but one day it stopped charging completely. When I press the reset button on the bottom, it powers on briefly and says the battery is low and needs to be charged. However, when placed on the charging dock, it does not start charging (no LED change and no charging indication).

What I have already checked:

The charging dock has power
The robot is correctly positioned on the dock
Charging contacts on the dock and the robot are clean
Tried multiple wall outlets

At this point, I would like to know how to repair it, not just identify the cause.

Questions:

What are the recommended repair steps to restore charging?
Is battery replacement usually the correct fix for this issue?
Are there known internal components (fuse, charging board, connector) that commonly fail?
What should be tested first after opening the robot?

Any step-by-step repair guidance would be appreciated.

Thank you.

Shark Matrix RV2310: Why does my matrix vacuum make a loud growling noise?

Fri, 13 Mar 2026 17:55:09 -0700

Matrix robotic vacuum makes a loud growling noise while running. Will make less noise without the side brush on. Suspect it’s coming from the gears or motor that turns the sidewall brush.

When I tell my i7 to vacuum, it comes off of the dock about 3 feet, and proceeds to just spin in circles. The wheels are clean, and the trash bin is empty. I'm not sure what else to try. Any help would be appreciated, we've only had this robot for 2 months.

iRobot Roomba 561: Error 2 clean the brushes

Wed, 04 Mar 2026 08:01:27 -0700

My roomba moves for about a minute then says I need to clean the brushes. The brushes are clean. I’ve replaced all brushes and battery several times. I recently took the whole thing apart because of this error. I cleaned the fuzz around the motor and other places. I can’t tell if the brushes are spinning while it’s moving although it does sound different than normal. I thought this was because I cleaned around the motor. I can find parts on Amazon. Should I replace the green housing that the brushes sit in or should I replace the round sensor in the housing?
