AussieBatt Vacuum Cleaner Battery Experts have done to improve the frustratingly poor performance of Samsung Navibot SR8855 and help make Samsung Navibot SR8845 Vacuum Cleaner Battery slightly easier to live with.
Best Practices for Maximizing Samsung Navibot VCR8855 Vacuum Cleaner Battery Life and Performance
If you look at your Navibot’s dust bin, you’ve probably noticed how the frame of that filter half-blocks the suction channel. How Samsung didn’t notice that themselves at the design stage we’ll probably never know, but with a sharp hobby knife you can easily cut out the obstructing part of the frame to open it up (careful you don’t cut into the filter itself – a thin lick of glue along that edge will ensure it’s sealed). It certainly improves the suck on my 8855 – not brilliantly, but to some degree. Cleaning used/dirty filters in an ultrasonic cleaner improves the suck quite a bit too.
2. Making the Samsung Navibot VCR8855 Vacuum Cleaner Battery run longer
Samsung warrant the Navibot battery for 6 months, and recommend replacing it after a year. There’s nothing inherently wrong with the quality of the battery in my opinion just that the Navibot treats it very badly, and my 18-month old battery was down to a best run-time of just 26 minutes. Cycling it slowly 5-times improved that to a consistent run-time of 67 minutes – as good as a new one.
3. Straightening out the curled-up side-brushes
No way am I buying new side brushes when there’s nothing wrong with the old ones, other than they twizzle themselves up so tightly the Navibot starts jumping up and down like a nodding donkey. Piece of wood, 4 screws, leave them overnight, and they’re as good as new by morning.
4. Virtual Wall/Lighthouse AA rechargeable battery conversion
Anything that needs batteries in my house will use rechargeable AA or AAA cells. End of. The trouble is D batteries give 1.5 volts each, yet AA rechargeable only give 1.2 volts, so you’ll need 3 rechargeable AA cells to make it work… and work brilliantly it does too. 3 AA cell battery holder and a clip easily available from Marlins or Radio Shack, it fits in the device perfectly, and with 2000mAh or better rechargeable cells lasts just as long as typical D cells. I find “Hybrid” rechargeable cells seem to work best since they retain peak charge much longer than normal rechargeable battery cells.
