Window Cleaner Backup Battery Replacement

If your window cleaner backup battery is flat, it may need to be replaced. This will happen eventually if it’s not kept in top condition by regular recharging.
If the device is not currently working, then it could be that the on-board backup battery that has run out of juice, and can’t be recharged anymore. This can happen if the device is put away for a long time. Lithium batteries should be charged regularly to ensure they remain healthy.

Your Window Cleaner Has A Safety Battery

The robotzoo Gecko and Glider window cleaners make use of a small on-board lithium battery as a safety feature. The purpose of the window cleaner backup battery is simply to provide enough power to keep the device adhered to the window by vacuum pressure if there is a loss in mains power.

Removing & Unplugging the Battery.

The battery is fastened into an enclosure with double-sided tape so as to ensure it does not bounce around when the cleaner is working. It has a lead, approx. 10cm long, which connects to the main controller board.

Plugging In & Fastening the New Battery.

The new battery should be fastened into its enclosure with double-sided tape so as to ensure it does not bounce around when the cleaner is working.

When plugging the battery in, also check that the main board is securely fastened to its 3 mounting points. Sometimes these mounts can break. If it is not secure, remove the mounting screws, and fasten the board down with slightly larger screws.
