As an ordinary housewife, I do not recommend this tool if you need to clean your house from mold. It does not cope. The battery runs out quickly (it's good that there are two of them in the kit), you need to collect water in a bucket and carry it with you (yes, it is convenient in positions where there is no access to water, but am I tired of endlessly filling the bucket? Very tired, because the water consumption is high). You still need to use a brush, sponge and detergents, because the water pressure is not strong enough to clean mold. Probably more suitable for regular car washing. Quite fast delivery and good equipment with quite convenient packaging
