Samsung NaviBot SR8855: circuit diagram or schematic for accu loading

Sat, 22 Jul 2017 10:15:46 -0700

The Bot Device cannot load his accu.

It does not recognized the contacts of the docking station. It still search and find the docking station well, but search endless the loading contacts.

I'm still good in electronics but do not have any schematics and don't kow any about the firmware/programms of a lot of microcontroller build in.

Samsung POWERbot R7070: PowerBot R7040 Runs with disengaged powerbrush

Tue, 04 Jun 2024 17:23:15 -0700

my powerbot recently started to show this glitch where it actually runs pretending like it is cleaning but without actually vacuuming anything.(no powerbrush running) If i hit pause and then start again it starts and runs as expected. I’m not sure how often does this happen since it cleans mostly when I’m not home. I was only able to catch this on weekend.

Samsung Powerbot R9250: Water vacuumed up - vacuum stopped working

Sat, 15 Aug 2020 17:45:32 -0700

My Sammy is dead! Sammy sucked up some water and quit working. I dried it out by setting it out in warm weather and in the sun and cannot get it to come back on or connect to the recharge station. I have switched it off and on and done numerous things but no luck. I have done all kinds of internal checks but cannot see anything to trip other than the master switch. Is there a fuse or something else I need to check to restart. I did not see very much water in the dust bin.

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.

Samsung POWERbot R7070: Left wheel is not working properly

Fri, 15 Jan 2021 13:51:01 -0700

I recently bought a refurbished powerbot r7070 and the left wheel stopped working. Everything was great for about a week before this issue occurred. I was hoping it was a minor issue but when i opened it up i couldn't see any jam or other visible issues. I am assuming it is the motor for that wheel. I called samsung and they dont sell parts for this model anymore.... So i am not sure what to do. I love the vaccum and i can get a refund for it but i got it at a once in a lifetime deal and would have to pay hundreds more for the same model =/

Samsung NaviBot SR8855: Short shift and turn.

Fri, 21 Apr 2017 10:36:18 -0700

Navibot sr8855 after repair of FET tranzistors for brush have bad mooving - navigation.

From the beginning it worked well and after some time was problem in navigation.

It looks like that: move 20-30cm stop and go back about 3cm, turn 90st. and repeat.

Sometimes work good for 1 minute and then again fail to this state.

I try test mod and all sensors look fine, motors are OK too.

Samsung Powerbot R9250: My power bot is just blinking when I try to charge it. do you repair?

Thu, 10 Jul 2025 10:14:10 -0700

I have a Samsung powerbot and it just stopped working one day. I have tried to replace the battery and the charging station but it does the same thing. When I move the powerbot to the charging station by hand, it starts to blink when on the charger. Then after a few mins it stops and will not charge. I am unsure if it is a fuse or what but I am looking for someone who can help fix it or someone who will repair it. I have contacted Samsung but they company they refered me to does not do repairs. It is just over a year old so there for my warranty is no good any more. Is there some place that will work on them or is there someone who knows how to fix it?

I have a VR9000 samsung robot which I love.. only problem is the battery has now begun to not hold its charge for very long. I have looked online and can find nothing for less than AU $300 which just seems far to high for a Battery.

Is there any other alternatives or sites i can buy an aftermarket or second hand battery?

Samsung POWERbot R7070: Powerbot won't turn on at all

Sun, 16 Jun 2019 17:03:15 -0700

I have had my Powerbot R7070 for a bit over a year now, so it’s no longer covered by warranty.

Recently it stopped turning on, and I was told the problem would likely be with the battery. So, I ordered a new battery and replaced it.

The powerbot still won’t turn on.

I have followed directions on samsung’s support website, about letting it charge for a while, then toggling the emergency switch off and back on, then holding down the start button, but there’s no indication of the powerbot getting any power.

I also checked the charging dock’s charging pins with a multimeter, and it seems to be working fine, so something is wrong with the vacuum itself.

Any ideas?

The main board does not control the battery. It always shows one digit of charge. The battery is brand new. I noticed that R109, R107 have different values. Do you have a circuit diagram of the main board or tell me the values of resistors R109, R107. Thank you.
