Vacuum will run for 5 minutes and shut off,

The motor probably has a heat sensor overload protector to protect the motor from burning out its motor windings. There is nothing wrong with the vacuum itself.

what is the shroud ?

It's overheating. Empty the cup and replace the filters. There's a breaker that opens up and turns it off when it gets too hot. When it cools down it closes back up and it will run again. It'll argue with you til the end of time or until you fix the problem.

Good Luck

If you have BISSELL vacuum, some of our models have a brush reset. Here are the instructions to turn it back on:

If something becomes lodged in the foot and the

brush shuts off, turn the cleaner off and unplug

from the outlet. Remove the obstruction. The

brush will automatically reset when the cleaner
is plugged in and turned back on.

Additionally, you could have dirty filters that are activating a thermal protector switch that shuts the vacuum off if the motor becomes too hot. If this is the case unplug the vacuum, clean any filters, clogs, or obstructions and wait 30 minutes for the unit to cool. Then plug the unit in and it should work. I hope this helps.

The problem is not the battery pack. It is in the electronic over current circuit that prevents a possible overheating of the battery pack. My unit will run for 10 - 15 seconds and then shuts off. The over current sensor is reset by moving the power switch to the "OFF" position. If you turn the vacuum back on it will run for a few more seconds before shutting off again. There is a small circuit board in the vacuum that contains the over current protection circuit. It uses an NXP Semiconductor HEF4001BP quad 2-input NOR gate. If you are good at soldering you might try replacing this chip. Otherwise, buy a new vacuum. The problem is not in the thermal circuit breaker located in the handle. I have bypassed the breaker and the problem still occurs.

2 speed E2 models have a circuit board inside that controls the machine. It sounds like this controller board may be bad. The unfortunate part of this is that the board is not only very expensive, but it is only available from an authorized Rainbow service center.
Use caution if you decide to work on this yourself or if you take it to a service center that is not famliar with these models. The circuit board mentioned above is susceptible to damage from static eclectricity discharge. The static you generate from just walking across a carpet could make this board useless. So, if the original problem is not the board you could make the problem worse.

Sounds like it is over heating do to a dirty filter. Or there is something blocking the air flow in the vacuum.

You have a plugged vacuum indicator port. There will be a tiny hole somewhere near the hose inlet. Just clean it with a dry toothbrush. This will allow the vacuum pressure to equalize on either side of the shut off switch.

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

Does it shut off with the hose removed? If it does then there is a problem with the electronic control(mounted by the motor), or the motor itself. If it doesn't, then there is a clog in the hose, wand, or powerhead.
