This is usually not due to the product itself, but to damp residues in the wiping system. What we recommend: -Clean or replace the wiper/roller immediately -Thoroughly clean the fresh and dirty water tank -Wipe out the inside of the dock / cleaning station -Test once with clear water (without cleaner) to narrow down the trigger If the odour persists, there may be a hygiene problem in the wiper circuit. The product should then be checked.

Hi, like you, I noticed the difference before I bought it. However, the difference is not significant or measurable for me. The version I bought was the cheapest offer of this brand / type. Another reason why I didn't check the technical part with the approx. 10% difference in suction power. Apart from that, I have set up the vacuum cleaner in the cellar as a stand-alone unit and it works perfectly. I'm very happy with it. What I don't use is the detergent dispenser. As I have parquet everywhere in the flat, I am simply careful and clean with cleaning agents that I know and traditionally with a hand wiper. Best regards MG

Standalone.
