Interior cleaning is usually the part that slows down a wash or detailing outlet the most, especially if the vacuum being used isn’t built for constant use. Manmachine Works has car vacuum cleaner machines meant for commercial setups — the kind that get used vehicle after vehicle through the day, not just occasionally. Suction power and tank capacity differ across their models, so it makes sense to compare a few before picking one that matches how busy your outlet actually gets. Worth a look if your current vacuum is struggling to keep pace.
