4296 Robotic Vacuum _ Brush quit spinning

The brush quit spinning. When I turn it on in any mode, it just creeps around very slowly. Motor/drive wheels run but it moves very slow and the brush will not spin. Sometimes, if it try to turn the brush by hand (this is tricky to do) it will spin for a second or so but won't continue. It has been been well cleaned. The brush will turn free manually and the gears seem to work as the rubber roller turns with it. And as I said, it will work momentarily sometimes if I can start the brush but it doesn't always start and never stays running for more than a second or so?? Anyone have this problem and/or a solution besides replacing it??

Thanks

I had the same prob. i contacted i-robot and was told the motor that turns the brush is shot. there is no replacement part. they offered to replace my i-robot with a new one from the 400 series. at about 60% of a new one. that's the only option that i know of.

Dyson DC25 brush won't spin when touching the floor. If I lift it off the floor it spins, once it touches the floor it stops. Any idea what the problem is?


I can think of three things that could be wrong.

The easiest one is that the brush has hair and fluff wrapped around its bearing. This happened to me and was causing a burning rubber smell. Turn it over and remove the base plate. Lift the belt by putting a piece of cord under it and slide the brush out. Remove one end of the brush and slide the spindle out. Clean all the hair out and reassemble.

The internal drive belt is worn, or the nylon bush that it runs on.

The clutch is worn out.

The last two are not as easy to fix as the main drive belt is enclosed in the centre of the clutch. There are videos though that show you the process. Have a read and a watch, but try my first tip first.

    Why isn't the side brush spinning anymore?


    It sounds like you need to get a new brush motor. They are modular and easy to replace.

    Brush roller not spinning. belt, spindle okay. roller taken out and cleaned, no thread. replaced but no dice. ???


    Use only BISSELL Style 10 Replacement Belts (#32074) in your BISSELL PowerForce Bagless.
    1. Unplug cleaner from electrical outlet.
    2. With Rotating Floor Brush removed from vacuum cleaner, grasp old Drive Belt and remove from Motor Pulley. Discard old Drive Belt.
    3. Place new Drive Belt over Motor Pulley and stretch other end over Rotating Floor Brush in the space between the bristles.
    4. Place ends of Rotating Floor Brush down into slots on sides as shown.
    5. Turn Rotating Floor Brush by hand several times in the direction of Motor Pulley. If properly installed, Drive Belt will center itself on Rotating Brush.
    6. Reposition Brush Cover and snap back into place. Check to be sure all three latches are secured.
    7. When you turn on the vacuum, do you see the motor that spins the belt spinning at the bottom? If not, it sounds like you may have a burned out motor.

    Brushes not spinning


    Side brush? Main brush? both? How did you find that they are not spinning? To properly test, place the front wheel on the table edge and hold the wheels up in the machine (dont hold the tires) , Then start the clean mode.
    If it doesnt spin then you need to open the roomba and remove the motor to see if it is just binded up with lint. If the motor spins with your fingers then test the motor with a power supply to see if it is possibly burnt out. If it works on a power supply then your issue is on the main board and it needs replacing.

    Brushes not working


    if the brushes are clean and yellow ends on the brushes spin freely, then you've done all you can without replacing or reconditioning the brush drive assembly. If its under warranty replace the assembly.

    If the warranty has expired and you have the skill, you can remove the assembly and vacuum it aroundthe motor. Next remove the screws from the side plate to reveal the gear train. Its probably full of dirt you should clean out. Oil or grease would accelerate the rate at which dust is trapped. To lubricate the gear faces and pivots points I recommend dry powdered graphite. Its available at hardware stores and its most commonly used for lubricating locks, and woks well for me in the Roomba brush gear train.

    Irobot roomba brush only spins on hardwood/tile. brush stops when it hits carpet. motor prob's? fix?


    Remove and clean the yellow bearing on each brush, then reinstall them. Run the Roomba and ensure that the brushes do turn on hardwood, then test it again on carpet. If the brushes still stop turning on the rug, call customer support at 1-877-855-8593. They'll be able to determine your warranty status and discuss your options.

    Irobot roomba 570 brush not spinning


    Unscrew and remove the side brush. There is probably a wad of hair and dirt underneath it that's keeping it from spinning. When it's clean, *snap* the brush back on, then screw it into place. If it still doesn't turn, you'll need a new module. Call support: 877-855-8593. Good luck.

    Irobot moving slowly


    Try running th roomba with the dust bin removed to see if the main brush is turning, if not it could be an issue with the gears being stripped in the brush motor assembly or inside the brush compartment holder. If the gears are fine the brush motor itself may be blown. A new one is about $30.00.
