Getting the best from your battery

We engineer vacuums that are simple to use and easy to look after. But batteries contain complex chemical structures that react to their environment. We've put together some tips that will help you to get the maximum life from your battery.

  • Use high power mode less

    Your vacuum is designed to be used in Auto or Normal mode for everyday cleaning. These can be found and changed at the top or back of your vacuum. Max or Boost modes are meant for powerful, intensive bursts of spot cleaning. Using them constantly speeds up degradation of the battery. If your machine has Eco mode, run time is maximised for a longer clean.

  • Avoid use in extreme heat temperatures

    Hot environments speed up battery aging. So it's best to avoid cleaning the car in hot weather or leaving your vacuum in rooms that experience direct sunlight for prolonged periods. The same goes for cold porches and garages in winter.

  • Store your vacuum at room temperature

    Heat sources, such as radiators, can damage the battery. We recommend that you store your vacuum at temperatures between 18°C–28°C, away from direct sunlight and out of boiler cupboards.

  • Let it cool, but not too much

    You can preserve the life of your battery by letting your machine cool down after use – before connecting it back up to the dock to recharge.
    Your machine won’t operate or charge if the ambient temperature is below 5°C (41°F). This is designed to protect both the motor and battery.

  • Give it a break

    By letting the battery run down to empty at least once a month, you'll help to prolong its life. If you have a spare battery, we recommend you swap them out from time to time, so that they both have time to naturally discharge.
