How to Identify and Fix Common Vacuum Problems ?

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

Even a half-used battery can be recharged. The important point isn`t how much the battery is charged, but how much capacity it has. For example, the used battery may be able to power a load, but it will do so for a much shorter time than a new, unused battery.
One of the most common reasons your battery backup sump pump won`t run is an improperly installed switch: The switch needs to be attached right above your primary electric sump pump, so that it only turns on when your primary fails or is overwhelmed by the amount of water inflow.
During the testing process, keep an eye on the battery indicator light. If it remains green, it is a good indication that your battery is strong. Fortunately, battery backup sump pumps have alarms that alert homeowners when the battery is nearing the end of its life.
The reason that you should never unplug your sump pump is that water can drain into the sump pit at any time, even in the dead of winter. Even if the ground is snow covered and is frozen a metre of so below the surface, it may not be near the footing or bottom part of the foundation.
Make Sure Your Sump Pump Always Has Power

Your sump pump may be in great condition to handle your water needs, but that won`t do you any good if it`s not plugged in.

As a general rule of thumb, during a power outage most new fully-charged batteries will last roughly 5-7 hours of continuous pumping and roughly 1-3 days of non-continuous pumping depending on the frequency. The longer the pump runs, the less power it has.
If your sump pump has no power, check the following: Make sure that it is securely plugged into your power outlet and that it wasn`t accidentally unplugged. Make sure that the breaker for your sump pump hasn`t been switched off. Make sure that your battery backup hasn`t run out of power.
What do you do when the power is out, and you forgot to get your backup battery installed? You can keep the water flowing out of your basement using a sump pump generator. An uninterruptible power supply will provide you with an assurance your basement will keep from getting any water damage.
A worn-out or malfunctioning float is sometimes the reason your sump pump has stopped working. Fill the sump pit with water and that should make the pump start on its own. If it doesn`t start, the float may need to be replaced.
As a general rule of thumb, during a power outage most new fully-charged batteries will last roughly 5-7 hours of continuous pumping and roughly 1-3 days of non-continuous pumping depending on the frequency. The longer the pump runs, the less power it has.
It depends on the size of the battery and the sump pump system that is doing the charging. The Big Dog system has a powerful 20-amp smart charger that will charge a discharged battery in approximately 6 hours.
When to Replace the Battery in Your Primary Sump Pump Battery Backup. Most battery backup pumps will last for 3 to 5 years, but there are a few things that can shorten their lifespan. If you live in an area with frequent power outages, your backup battery will be working harder and may need to be replaced more often.

I purchased a brand new P113 Ryobi charger about 2 years ago. It has never worked. If I put a P104 battery in for a charge, it looks like it works correctly. I push the battery tester on the battery itself, and it says full charge, but when I go to use the bateery, it dies right away. I have tried three new P104 batteries. The batteries charge on my charger at work with no problem. The funny thing is, I don't need a battery in the charger and the charger does the same thing, It runs the test
ANSWER : If you have your receipt, check with Ryobi to see if it is still under warranty. It comes with either a 2 or 3 year warranty, depending on when it was purchased. If it is still covered, get it replaced/repaired. If it is not, buy the P117 charger. $30 at Home Depot. It has a 90 day satisfaction guarantee. If it charges your batteries properly, you’re good. If not, bring it back if you don’t like/want it. My P113 won’t get out of test mode now, or charge Lithium batteries anymore. So I bought the P117 yesterday. Works great, and it’s a lot cheaper than new batteries! And it has a 3 year warranty.

Battery charge I just purchased a new battery pack insert for my Roomba, Replacement
was a breeze and it now works great. My question is; The last battery I
bought ( not from you) was a full cased roomba battery pack that didn’t
last a year. Roomba says leave the r Roomba charging all the time so
it’s ready when you need it, and that’s nice but I feel that leaving it
charging like that it will kill the battery faster as it is always warm
to the touch. These battery’s should last at least 5
ANSWER : Dave you are correct. You should never over-charge anything like a Roomba, Cel Phone, etc. That will kill a bettery very quickly.

My Roomba Discovery 4210 seems to be dead. Specifically, with or without a battery, and whether on the charging station or plugged directly into the charging unit, I see no lights on the display whatsoever. This unit has a history of killing batteries, but now seems like it is completely dead. I understand that the batteries themselves contain fuses; is there some way to bypass the battery (for now) to verify whether the unit itself is completely dead? I should also note that this is the sec
ANSWER : Hello,

I will advice you remove the batteries from your Roomba Discovery 4210, after removing the batteries, plug the Roomba Discovery 4210 directly with the charger to an AC outlet, see if charges, if it does, it means the batteries are dead and will need to be replaced.

Take care.

Hooked everything up per directions. I plugged it in to the closest electrical outlet and nothing happened. The lights did not light up, the connected wall control and sensors leds do not light up. It appears the unit doesn’t have power. The electrical outlet socket is fine as everything else I plug into it works fine. I have tried every other electrical outlet available. The unit won’t power on from any outlet, and all of those outlets run other things, like power tools an refrigerators
ANSWER : Dear Davehibshman,

Firstly; dismantle the plug and replace the fuse with the same rating as the one you have just taken out. Replace the plug cover, put the plug into the socket and try again. If this doesnt work, there may be a problem with the internal fuse (if one is fitted). Two choices here, either refer this unit to a qualified service personnel/ the place where you got it from, or do the job yourself (which will save you a whole bunch of cash). In your circumstances, I would take it back to the place you got it and ask them to put the fault right, or replace the unit completely; if it is past its warranty or guarantee time, then get back to me with a make and model number of the unit, and I will give you step-by-step instructions on how to solve this.

Yours sincerely

Oz

I cannot charge my two year old electrolux pronto. I purchased a brand new hand held vacuum for it, but even the new one does not charge. When I plug in the cord nothing happens. If I turn on either the long handle or the portable unit within the long unit, the blue charging light comes on for a few seconds, then out. This tells me that the circuit is intact without a broken wire somewhere. I took it all apart carefully and could see nothing broken or out of place. On re-constructing it, it
ANSWER : It must be the charging transformer. We have already ruled out the vacuum unit. Unfortunately the transformer is not a serviceable part, and will need to be replaced.
