Possibly a faulty power cord, replace the power lead to the machine or check for damage to the cable.
Check that machine is not blocked, motor may be overheating due to blockage, if you have good suction this indicates machine is not blocked.

Need some more information, are you vacuuming dry wall dust or wet dust or saw dust ? The reason I ask is sometime their are "upgrades" available for the newer models of vacs you may not be aware of, when I worked at the Big Box H D tool rental center the vac we rented out used a water filtration set up instead of bags U might wont to check newer model for any changes, like you ,I had Craftsman for over 15 yrs. and when it died the replacement vac had a new mod for the filter that I always thought was needed. Good luck , Bret

Some of these units have had trouble with the motors and this is what causes them to shut off. NuTone has been pretty good about replacing them under warranty. 1-888-336-6151.

Roomba keeps saying clean brushes yet are clean!


Make sure you take off the little cap at the end (the one that spins -- just grab it and pull it straight off) and clean under it too. The rest of the brush may look perfectly clean but what happens is that hair gets stuck under spinning cap and, like a slowly growing washer, it pushes the whole brush toward the gear box. When it gets pushed over enough, the large yellow ring starts to rub against the side of the brush deck making it harder for the motor to turn the brush and you get that "remove and clean brushes" message.

make sure your knob is set to the right hose diameter, the inner cage is properly seated inside the filter and your float is not being obstructed by debris.

Nutone central vac vx550


It's a known problem. I bought my vx550 last year in July and it stopped working this year in May. On for 5 minutes, shut down, can't run for a few hours, runs for another five minutes, etc. I called the Nutone customer service department and they exchanged the unit for a new one, cross shipped, via UPS. Mine was still under warranty though. It has to do with some defective thermostat or controller in the electronics of the vacuum.

Good luck

Replace the O Rings and the trigger valve assembly. 9/10 sticking rods on the Porter Cable guns is caused by a faulty TVA.
