Vacuums\015 Shop Vac model 90LN purchased in November 2006 (just out of warranty) will not power on @ switch on top of vac. Tried different outlets to no avail. Vacuum is clean inside/out and only used approx. 4 x's year x 6 yrs. = maybe used 25 times since purchase from Lowe's. ..Is there a fuse/breaker on vac? Possibly needs new switch. Have user manual w/parts listing but am unsure of which part to order. Any suggestions would be appreciated.\015

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
The bottom line is that Shop-Vac units shouldn`t be utilized without a filter. The vacuum will work without one, but it might not work better. Numerous other consequences might occur. You may create an even bigger mess than the one you needed to clean.
Overheated Motor

If your vacuum was working fine and then suddenly shut off, it may have overheated. Most vacuums are equipped with a thermal protector safety switch that won`t allow the motor to run when it becomes overheated. You will need to wait for 30 minutes to 2 hours, depending on your machine, to try again.

Most types of vacuums last around 5 to 8 years, with brand and lifestyle making the most significant difference in lifespan.
Check both ends of the tube for any debris that may clog the machine. Make sure to empty dirt bin and clean the filters if they are dirty. If you experience no suction when using a tool, remove the tool and check each opening for clogging.
But a shop vac has two holes. One hole near the top permits replacement air to enter the container. When a hose is attached to this hole, dirt and debris can be sucked into the container. Air circulates out another hole to equalize the constant airflow in the shop vac and keep the motor cooled as it`s being used.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. 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.

I do not have my users manual and have never vacuumed wet with this vacuum. How do I change it from a dry to wet vacuum.

lost my user manual never used it to pick up water. need to know how to puit it in wet mode i want to clean the dirty water out of my pool.
ANSWER : .Vacuuming Liquids
.1. When picking up small amounts of liquid
.the filter may be left in place.
.2. When picking up large amounts of liquid
.we recommend that the filter be
.removed. If the filter is not removed, it
.will become saturated and misting
.may appear in the exhaust.
.3. After using the vac to pick up liquids,
.the filter must be dried to reduce the
.risk of possible mildew and damage to
.the filter.
.4. When the liquid in the drum reaches a
.predetermined level, the float mechanism
.will rise automatically to cut off
.airflow. When this happens, turn off
.the vac, unplug the power cord, and
.empty the drum. You will know that the
.float has risen because vac airflow
.ceases and the motor noise will
.become higher in pitch, due to
.increased motor speed.
.IMPORTANT: To reduce the risk of damage
.to the vac do not run motor with float
.in raised position

Infinity Vaccum by Shark, model number NV31COS, will not start. The vacuum was running just fine until it grabbed the edge of a curtain. Turned it off to release the suction. Turned it back on and was working fine. About a minute later the vacuum was making an odd noise. Every 2 seconds or so it would “heave” (lack of a better word) then go away, then come back and so on. Turned the vacuum off and checked for blockage, none that could be seen or felt, and now the vacuum won’t turn. Any suggestio

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.
