Having problems with your iRobot Roomba 560 Robotic Vacuum ?

My Discovery 4210 Roomba will run normally for about 20 minutes on a smooth, wooden floor. It then begins the following sequence: run forward a few inches, turn in a tight counter-clockwise circle a few revolutions, stop, power off a few seconds, power up, repeat cycle from forward run. The sequence can be repeated seemingly endlessly if I don't turn off the power manually. I've replaced the motor, and led revolution sensor system on the left drive wheel. I've blown the dust out of everywhere. A

Answers :

This robot vacuum has a electronic micro processor that controls the unit and tells it how to operate and where to go based on programmed parameters. It's quite a technical marvel. I have dropped a link here for contacting the company tech support line. They will be able to find a replacement part or give you the correct solution to the misbehavior of the machine.

Go here:

It sound like your Roomba is doing the "Circle Dance". Even though you may think you have thoroughly cleaned it out the problem most likely is the optical encoder. Despite the snug fitting hub cover, dust can still enter. When the optical encoder used to sense wheel motion get even a little dirty the dreaded\015\012"Circle Dance" ensues.
Since I am not familiar with your specific model and I am unsure to what extent you have disassembled your Roomba, I can only give general steps.
You need to to gain access to the optical encoder. This means the body needs to be separated. Also any fender attachment and the hub cover. Under that you will find the optical encoder along with the drive belt and wiring for the encoder. A can off compressed used for cleaning keyboards works best because it's clean air unlike what you might get from an air compressor. There is really on need for further dis-assembly from this point. If you need more specific details on a particular area or are unsure about anything please don't hesitate to ask.
Hope this helps.

Tell the truth. You just love taking it apart don't you. :)

Kenmore canister model 116.25513506 wont turn on. when handle switch is turned to floor. vac motor does not turn on. When switch is turned to carpet, floor nozzle works but vac motor does not. I checked fuse, all o.k. checked continuity for plug, o.k. removed wires for bag full switch...motor wont run. I wired motor directly power cord...motor runs.

I have a Kenmore Elegance Vacuum with Dirt Sensor, Model # 116.30750400C, Serial number M41901532. When vacuuming the carpet the power head will work for 3-6 mins then automatically shut off, power is still there and lights work but the power head motor turns off and the suction stops. I will turn it off and on, check the outlet, flick the on off buttons...nothing. I will turn it off for a couple minutes and it turns back on and runs like normal.

Power nozzle on E-series won't start when cold unless the red 'reset' button is pressed multiple times while also holding the trigger to 'warm it up'...this is w/the power nozzle off the floor - no restriction on it turning. Once it's been running and then turned off the button must be pressed w/the trigger to get it to run - again w/the nozzle off the floor. It also seems to shut off too easily while vacuuming.

Lately, my Kirby Ultimate G has been acting funny. When I push it forward, it's fine, but when I pull it backward on the carpet, the light on the front flickers and the power flutters off an on. I thought it might be the rollers, so tonight I turned the machine over and pulled out the hair that was wrapped around the roller. However, that did not fix the problem. I should probably backtrack a little bit. In the past, I have had problems with the vacuum running over its own power cord.

The cord will need to be replaced with a cord made for the machine, as it has a non-standard plug. The cord cover is held in place with a # 20 Torx screw. Remove the screw and push the cover gently from behind to unlatch it. The handle must also be r ... Kirby Ultimate G Bagged Upright Vacuum

After using the vac for 10 minutes or so, the motor starts turning on and off with greater frequency the longer I let it run. Eventually it is on and off so frequently that it has no power. Would this possibly be the 24V relay? I have checked the breaker on the unit and it is not tripped. Does the motor have a thermal overload switch separate from the breaker?

No it dosen't. I fix central vacs all the time and relays usally don't do what you described. They either go out all the way and won't turn on or they will trip and you will have to push the breaker back in. What is probably happening is you have a s ... Electrolux Centralux Vacuum

Hello, I have a problem with my Eureka Powerline bagged upright vacuum. It has a 12 amp motor and is model #4352, Type D. It was probably bought new in 1998. My problem is, while vacuuming today the motor seemed to slow down all of the sudden and then began smelling like burning rubber. I shut the vacuum off to check for blockages but could not find anything blocked. When I then turned it on again it runs but seems to only be running at 1/2 the motor speed and still has the rubber buring smell.

It sounds like a rubber sealing in the motor has come loose and is being constantly rubbed against the walls of the motor with would cause the smell and loss of motor speed caused by the fricton of rubber against the rod so if you can get to the moto ... Vacuums

Unusually when it is running and I block the intake it will run at full power but as soon as I clear it the motor "hunts" again. Any ideas.

I have Nutone VX550C. Motor runs intermittently (cycles on and off rapidly--the light on the handle is blinking furiously) when I use the on/off switch on the hose. This happens at all of the wall connectors, so suggests a hose contact problem. Motor runs continuously when I turn it on at the switch on the wall unit.

The unit does have a switchs the PVC outlets, and it sounds like the hose mech to operate the switches is broken, and intermittently making contact. A replacement hose would likely fix the problem. Looked them up on the net, and they're not che ... Broan-NuTone VX550 Bagged Central System Vacuum
