iRobot Roomba 4210 Bagless Robotic Vacuum\015 Hi! My roomba 4210 front wheel is having problems with the rotation sensor. I tested it and does’nt switch 0 to 1. I made all the diagnostic tests. Left wheel running alone (separately) fine, also the right wheel, the side brush, the vacuum and all the sensors (bumper and the others) exept the front wheel rotation sensor. But, the big brush just make a pulse (start’s and stop really quick with no 360 degre turns) and roomba turns off. Also, when the two traction wheel test is selected it only make a pulse and roomba stops again. If I want to stop the diagnostic tests with the power button it flash red quickly until the battery is removed. No sounds from my speaker. I took apart my roomba and cleaned everything (sensors, brush,electronic) but only with compressed air and paper towels.Nothing changed. Could the front wheel rotation sensor cause all these problems?? I also changed the mainboard for a other working one and now the side brush is the only motor working and all sensors (the front wheel sensor is not changed yet). I unpluged and tested the big brush motor with a 9V battery and turns fine. Please help me cause I’m out of ideas. Thanks a lot!!\015
How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
Wheel and Axle are categorized as a simple machine. During movement, the force of friction acts in the opposite direction to the force exerted. This enables the object to move forward with the least resistance. As the axle is attached to the wheel, it acts as a fulcrum.

I have a rear wheel that came off too. The wheel seems fine, but the plastic base that the wheel clicks onto on the underside of the vac seems to have cracked. I need a new plastic bottom. Any ideas?
No more problem.
.Before you open it up I recommend following the diagnostic tests to see if its a physical problem (bad motor belt, hair stuck around the wheel) or a sensor problem (dirt makes Roomba think it is stuck when it isn’t). If you follow the diagnostics one of them will move the Roomba wheels while ignoring the sensors; if the wheels move fine then you probably have a sensor problem..
