How to Identify and Fix Common Vacuum Problems ?

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 air filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner`s manual for cleaning instructions.
Locate the brush reset button on the lower back right of the vacuum. Press the button to reset the brushroll To ensure the brush has been reset, plug the vacuum back into the electrical outlet.
In vacuum handling technology and other applications that operate in the rough vacuum range, the vacuum level is typically measured using direct-reading gauges. Direct-reading gauges can provide an accurate measurement from atmospheric pressure down to about 1 Torr and in some cases lower.
There is no sweet spot for robot vacuum dimensions that we could determine—it really depends on your particular room layout—but a diameter of 13 to 14 inches and a height of 3.5 to 4 inches are the most common measurements we encountered.
One of the easiest ways to increase vacuum cleaner suction is to empty the dust bag or container. Dust containers need to have enough space for airflow, otherwise, they could get clogged and have less suction power. Regularly check your dust compartment and empty or change it when it`s already 70-80% full.
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.

Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

First, check that the cord is properly connected to the vacuum cleaner (again, this is surprisingly easy to overlook) and that there are no splits in the rubber. If the cord is damaged, it will need immediately repairing or replacing. The on/off switch can break over time and need replacing.
What`s happening with your vacuum cleaner is that a clog has built up and debris being agitated by the roller is spitting out or stirring up dust without sucking it in.
The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH2O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m3/h or in l/s.
Normal Engine Operation

At idling speed, an engine at sea level should show a steady vacuum reading between 14 in. and 22 in. Hg. A quick opening and closing of the throttle should cause the vacuum to drop below 5 in., then rebound to 23 in. or more.

Traditional vacuums generally offer more power, too, which translates into more suction. While robot vacuums can easily handle low-pile area rugs and runners, traditional vacuums are better suited for homes with wall-to-wall plush carpeting and much larger areas.
A: The Roomba can fit under an end table or sofa as long as the height exceeds 3.7 inches (which is Roomba`s height). There should be a clearance of 1.5 ft (0.5 m) on each side of the Home Base and at least 4 ft (1.2 m) in front of the Home Base (with no furniture, such as tables or chairs within this area).
So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
Replace the Brush Belt

If the vacuum is still hard to push, tilt it back far enough that you can inspect the moving brush while the vacuum is running. Be careful to avoid getting too close to the moving parts. If you see that the brush is not turning, that means you will need to replace the brush belt.

On average, a well-maintained robotic vacuum cleaner can last up to 4-6 years, but some models may last even longer.
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.
If you get a more affordable model, like Roomba 675 you can expect a lifespan of up to two years. Go to the higher-end, like the iRobot j7+, and our research and testing suggest you can get five years plus of cleaning with proper maintenance.
In 2004 the Eureka Company name was discontinued and replaced with Electrolux Home Products Division, although the brand name was still used.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
If there is a clog in the vacuum, you won`t have good suction and the vacuum won`t work. The clog can be in the vacuum head, the hose or where the hose meets the actual vacuum.

Height adjustment The height adjustment button on my upright is nonfunctional.  The Height is set closest to the floor and it makes it difficult to move on medium height carpet.
ANSWER : You’ll have to turn the upright to its side to show the sole plate where the rolling brush is. Check where the front wheels are located and ensure there is no blockage obstructing the rotary dial. Sometimes the spring mechanisms can work themselves loose. ...
.Inevitably you’ll have to remove the sole plate and/or the rotary dial which may be screwed down. If it has cracked then you may have to seek a replacement. .

Vac is supposed to have auto height adjustment but it doesn’t
ANSWER : If the brush isn’t working then its maybe because the drive belt is broken. Locate cross head screws on top of the hood of the Eureka vac (two at the front usually and one below the duster or at the left hand side if looking at the vacuum from the front) Once the screws are undone check to see the drive belt is intact. If its not then replace with a new one and check at the same time that the roller brush is properly put in. If the drive belt is ok then check the brush roll – something may have jammed it if it isnt the belt. Dont forget to rate please.

I can see the height adjuster under my Bissell pet hair eraser vacuum, but it doesn’t adjust. The parts don’t look like they’re touching. It’s been iffy since I took it out of the box. Now it doesn’t adjust at all. Used only five times. Looks like I should be able to fix it myself. No local repair available. Could you help please?

.
.This is the pdf manual. If you look at page 12 you’ll see that the bottom of the machine has been pictured. Between the middle wheels near the brush (where arrows 4 and 2 are) you’ll find that the adjuster bar has a sprung mechanism. Now this is easy if you have time! If you take off the or just inspect the bar, check to see that nothing is clogged behind it. If it looks fine, check with your other hand by moving the rotary dial a couple of times and your other hand pressed down on the central bar between the wheels – if you can feel that the bar is moving whilst you turn the rotary dial then it should be working. Sometimes the spring that connects the dial to the bar can loosen and this may well have been the case. If you can unscrew the assembly do it gently as it will pop up to see if the spring has been put in place and then carefully put everything back together.

.Some uprights don’t allow the height adjuster to adjust whilst in the upright position though but if it doesn’t adjust at all then the spring has definately moved.

For some reason the adjustment thats in the front for lowering and highering doesn’t seem to be working is there a manual that I could see in adobe that would show me how this is supposed to be I think I have it on right but when I look at the bottom to adjust it doesn’t seem to do nothing [email protected]

Power nozzle not working on my vac but does on another vac
ANSWER : If pushing the reset button doesn’t help try having your local Aerus dealer check out the 2 prongs in the power head where it all connects. Sometimes they go bad.

Sebo auto X4 height adjustment not working
ANSWER : Worst case scenario is that there’s a fault on the circuit board, but another possibility is that the brush roll is not rotating freely. The automatic height adjustment works by sensing the drag on the brush roll, and altering the height to maintain constant drag. So, if the brush roll is sticking, the sensor detects the extra drag and raises the height accordingly. First thing to do, then, is remove the brush roll and remove any hair (the most common problem) or other stuff that may be wound round it – especially at the ends near the bearings. Check that the brush roll is able to rotate freely. .
.If this doesn’t solve the problem, the next possibility is that a spring has broken in the clutch/sensor device where the two drive belts meet. That will cause the sensor to “think” there’s more drag on the brush than there actually is, and hence to raise the height as before. This clutch (which isn’t really a clutch) has two toothed pulley wheels – one driven by the belt from the motor, the other driving the brush roll. Holding one wheel stationary, the other can be rotated slightly and there should be increasing resistance to that rotation. If the spring has broken there will be no resistance until you reach the limit stop. Unfortunately, if you’ve no experience of these units, it can be really difficult to know whether one is broken or not! The third possibility – failed circuit board – is, in my experience, the least likely. These are typically extremely reliable, and will usually last the life of the machine (25 years or more). I’ve never known one fail, but it’s always possible..
.I hope this helps. Any questions, just post here again and I’ll do what I can. Please remember to rate this response. Thanks!

Height adjustment not adjusting
ANSWER : The height adjustment wont engage unless the handle is in the down position. Not knowing this led me to overturn the hight adjustment knob.
.
.Step on the handle release, pull the handle back and lay the vac on its side. Then you can get the knob and the plate back together again.
.
.BTW, the reason I had this problem is because the front brush slows dramatically when using on carpet, I thought it was set too low, and turned the knob (in a manly fashion, putting it past its limit). Still working on that one. After inspecting the belt, looks like one worn and cracked spot gumming up the works.
