How to Identify and Fix Common Vacuum Problems ?

If your battery is not charging and the charger is rapid flashing and the battery is warm, it may be too hot– particularly after heavy or continued use. If so, please allow the battery to cool, then reinsert the battery on charger to try charging again.
The problem may lie in your vacuum cleaner`s adapter, charging dock, or battery and the electrical outlet. Try plugging your vacuum cleaner in to another outlet. If it is now working, the problem was in the first outlet that you have used. You should contact a certified electrician if you need to fix that outlet.
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.
It`s safe to leave your lithium batteries on charge over long periods of time, but in case of outdoor usage, you may want to store them away for winter.
It arrives fully assembled; you`ll just need to charge it before your first use. (It takes roughly 10 hours to go from a dead to full battery.)
Make sure the battery is fully charged, with the vacuum turned off while charging. After many cycles of use or after intense wear, the battery may lose charge over time or wont function at all. Contact Black and Decker for warranty coverage or replace the battery(!!! link to guide here) in order restore function.
The batteries can be tested at one of our service centers. A service center list is available on line at blackanddecker.com or by calling our toll free number 1-800-544-6986. The batteries can also be tested using a digital multimeter.
All cordless vacuums have limited battery life and need to be recharged. On average, you can expect a cordless vacuums` battery to last between 15 to 40 minutes, which is hopefully all it takes to clean your floors or furniture. Once the battery dies, expect to charge it anywhere from 2 to 16 hours.
The cordless vacuum cleaner should always be connected to the charging station.
Besides getting jammed with dirt and debris, the major problem that cordless vacuums face is a weak battery or failing recharger. Some cordless vacuum batteries are easily replaced while others are not and require that the entire unit be replaced.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
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 Jump Starter needs an initial charge of 24 to 48 hours. Please refer to your Use and Care Manual for further information regarding charging times. The units should be fully charged after each use and if the unit is being stored, it should be fully charged at least once every two months.
Under normal household use, the useful life of a 18v Ni-Cad battery is 150-200 full charge cycles before the user will feel that the battery should be replaced. The average number of charging cycles which can be expected from a Lithium-ion battery is 300.
After the initial charge, under normal usage, your power pack should be fully charged in 3 to 6 hours. If the power pack is run-down completely, it may take up to 6 hours to become fully charged.
Place the appliance on the charging bracket (4). Plug in the charger. Switch on at the mains. Leave the appliance to charge for at least 21 hours.
A: Your unit should be fully charged after 24 hrs. It is best to use the dustbuster until the battery runs fully down. Then it can be charged after that for its regular cycle of 24 hours. The red light will remain ON as long as the unit is plugged in.
The BMS doesn`t only consist of the actual battery but also the circuitry and other components; together, they ensure the right range of voltage and current reaches the battery for a duration of time. So, in that respect, you can`t overcharge your handphone or vacuum cleaner.
To sum it all up, the bare minimum that most manufacturers expect from their batteries is around 3 years or 1,000 charging cycles.
The battery might be dead if your vacuum is not powering up. After charging the battery for half an hour try turning on the vacuum again.
Some over-discharged batteries can be “boosted” to life again. Discard the pack if the voltage does not rise to a normal level within a minute while on boost. Do not boost lithium-based batteries back to life that have dwelled below 1.5V/cell for a week or longer.
The most common symptoms that come with a bad battery include: Battery light illuminated on the dashboard. Engine cranks slowly when starting. Vehicle requires frequent jump starts.
Don`t leave it fully charged (only recharge it fully just before you need to use it). When it`s not in use, a battery at 100% charge loses capacity faster than one that`s only partially charged.
