Anonymous1 year ago000After 5 months, the battery only lasts for 10-20 seconds... I don't think that's great. Does this happen more often, or do I simply have a defective product?Show in original language (German)Anonymous1 year ago • purchased this product000purchased this productThis must be a defective battery.

Also clean the filter. In our case, it worked perfectly again afterwards.

After about 18 months, it still lasts about 4-6 minutes I'd say (I've never timed it).Show in original language (French)Comment1 comment
