Bosch VXAS010V18 - well used, battery holds good charge, but impeller (the fan than sucks the air in) has shattered into pieces and it's over £150 for buy a spare battery-fan assembly. No way.
If you have this model and your battery is fading, this one can donate its battery without too much difficulty, if you have some DIY skills. Or if your charging stand is broken, or any other bit is dicky, this one can perhaps donate a (used!) replacement.
The attached photo is NOT of our vacuum, it's just one to show what the vacuum looks like. Photo doesn't show charging stand nor charger, but we have them.
