I saw this product demonstration on the Gadget Show. I was very impressed and ordered one the following day. I am disabled and have reduced fine motor skills in my hands. When the Household Sonic Subbed arrived I went around my home cleaning all those fiddly cleaning tasks that I found difficult using a cotton bud or old toothbrush. I ordered the Vehicle System to clean my all terrain wheelchair with mountain bike tyres, it’s so easy cleaning off mud and sand now. It’s definitely worth buying the standard for the household “Sonic”. It sits by my kitchen sink ready to spring into action at a moment’s notice. My “Sonic’s” have not disappointed me in all the cleaning tasks I have given them.
