Shark Ion Robot Vacuum 725/750/850 Grinding Noise Explained

If you have a shark ion series robot vacuum you might have a bad grinding sound coming from the robot mainly when its used on carpet or after something has gotten stuck in it. Here is the issue and the solutions that come with it.
Here is a list of the tools I use to work on these robots

Torx Bit Kit
Rubber Mat
Grease for electronics
Cleaning Supplies
New battery
shark iq
shark ion
Shark RV1001ae Spinner Brushes
Shark RV1001ae Brush Roller

Hi thanks for the videos.I’m going to buy the Torex bit you suggested so I can take apart the deep screws by the wheels. It looks like the left wheel (or motor) is cracked. I think there is some debris stuck in the machine because I smelled some burning. Do you still repair machines?

I have an 850 that I used on a hardwood/kitchen tile floor. Worked really well for a few months (bought it two years ago but my wife never got it going because of the need to get stuff out of its way, so I did on my own phone a few months ago). But it ran over a cord and now it makes a grinding sound. (Wasn't even all that bad; it barely got wound in before it got stuck and the roller stopped, but that's all it took.) Guess I need a new belt! Thanks for the advice, Smitty!

But how can I get that motor out? I need to clean behind the sleeve part! Do you have a video for the removal of this part? Please?

I need mother boards for three rv750. Do you have any? I also need two suction motors and some screws for the battery compartment. Can you help me?

I totally agree shark ion is one of the best. i have 6 of them. I got a RV700_N 14.4v needs the brush motor but now it just has a beep and no lights no acknowledgment that it's on base. will just beep every 5-7 seconds. this has got me scratching my head. any ideas? thank you

Hey Smitty...I have taken apart, cleaned, and re-assembled my Shark RV750 and now I keep getting the "cliff sensor" error lights. There is no factory reset option in the Shark App, I did the recommended reset, cleaned all the sensors, taken it apart, reassembled, etc. now 3 times. It is only 16 months old and in good shape. Help! Any ideas?

Do you sell belts? I believe the belt is bad on mine, and have tried shopping for belt, and talking to shark and they do not sell, for my RV750, thanks!

Where can I find a replacement belt? I cannot find one.

Where do I get RV 850 replacement belt?

I’m looking for a video or instruction on disassembly to get to the main motor and a side brush motor.

[BeardKing]

I have the RV750 and my main roller brush isn’t rolling. The main motor seems to be fine and spinning as it should. To me it looks like the main brush that fit onto the main drive peg is rounded off. So the drive peg is literally spinning inside the main brush. Have you ever heard of this issue???

[katalinvance]

Do you have just a strait forward remove drive motor and replace video? I’ve tried looking through your videos and couldn’t find it. Thank you !! Thanks to you I finally know what wrong with my vacuum.

My robot is making that loud noise. I do have the shaggy carpet so i think that it messed it up like u said. When i run it without the brush it doesn’t make the noise. Please help.

[hunterpalmer]

I have a RV 851 that keeps getting the stuck Brush roller motor error. I pulled the motor out and it seems to have like clicks. Is that normal or should it spin completely free? Thanks

[petecoulter]

I took my Shark RV1001AE apart to clean off my Ninja dog surprise and didn't take pictures on what wire goes where. Is there any guidance you can provide?

[bobwoodland]

Hi Smitty, I have a shark ion 750 robot that I let clean the dust under my bed. Some string got caught in one wheel and I got out as much as I could but the robot turns in circles. The wheels are under the bottom plastic cover. I got the Torx size ten screws out of the bottom but need to take off the side bumper which has an even smaller size torx screw that I can’t find a driver for. where can I find a torx bit to remove that small screw. Thanks

My shark ion is making a horrible grinding noise from the brush roll. It still spins and there is no resistance. Need to take it apart and see if there is hair in the motor drive. I took of the brush roll and it’s not making the loud noise. What to do next?

[jenniferwalski]

Just took my r75 apart. The motor appears to be okay. I don't see any signs of burning and it spins freely. No rattling when I shake it. I'm assuming maybe to start with the belt? Where can I purchase a new belt for this?
