Inspect the belt to see if it is broken, stretched out, or out of place. If the drive belt is broken or stretched out, replace it. If the brushroll is sticking, it will cause too much friction and put too much strain on the belt. Remove the brushroll and clean all hair, string, and lint from the brushroll bearings.
Durable – Vacuums made by Eureka are known to last for many years, maintaining the same level of quality cleaning power as the day they were first put into use.
To reset the thermostat, press the vacuum`s power button into off position and unplug the vacuum. Check the vacuum for potential causes of overheating, such as clogs or a full dust cup, and allow the vacuum to set and cool off for 30 minutes before turning it back on.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
The Dyson is slightly easier to maintain and has no recurring costs, while the Eureka has a HEPA filter that needs replacing on occasion. The Dyson is a bit more maneuverable overall, but its strong suction force can make it harder to move around on carpets.
On average, a well-maintained robotic vacuum cleaner can last up to 4-6 years, but some models may last even longer.
Introduction. This guide walks you through removing the Eureka SuctionSeal 2.0 Pet vacuum`s thermal fuse. You may find this guide useful if your vacuum isn`t starting and you have already tried resetting the thermal fuse.
The roller brush makes it possible to get dirt out of carpets. The roller brush is the combination of a belt, a roller, and sometimes a small vacuum head motor. The roller spins, and the bristles attached to it sweep up debris that then gets sucked into the dirt container of the vacuum.
A vacuum cleaner`s brush roller also called the beater bar assists in cleaning your carpets and depending on your vacuum model, a variety of floors. The brush roller is usually located under the vacuum cleaner and some in the attachment tool.
Founded in 1909 in Detroit, Michigan Eureka vacuums have been in American`s homes for more than a century. Now we`re building on that experience with innovative cleaning technology to help you clean for years to come.
You may have stalled the brush motor. To reset, turn off and unplug, then plug back in and turn on. The brush roll may have lodged debris or other entanglements keeping the brush from rotating. To fix, you`ll need to remove the brush roll to inspect.

Check for a plugged hose:

Plugged vacuum hoses are sometimes the reason for a loss in suction. Hoses can get clogged with hair, dust bunnies, string, or anything else that can`t pass through the other end of the hose. Airways inside the machine should be looked at as well. Wherever there is an air passage, check it.

Oreck XL How to remove rear wheel. Removed all viewable hair, thread, etc., but one wheel is still hard to turn. I think there’s hair stuck inside the wheel core. Can I remove the wheel & take it off the metal post?
ANSWER : You can take a medium size flathead screwdriver and slide it in beside the wheel and under the pin. Then pry carefully on one side and then the other it will start to come out but work both sides alternately so you won’t put too much pressure on the plastic. Once it is out you can clean it and put it back in. Line up the pin and use a blunt end tool like a punch to tap it back in. You can use the same screwdriver but don’t hit it too hard. You can tell when it is in all the way when it bottoms out. Make sure you look closely at it before you take it out so you will know what it is suppose to look like.
