  TL;DR: A foam cannon wins for deep cleaning when you already own a pressure washer, because it produces thick, clingy foam that removes heavy dirt. A foam gun wins for simple, budget washing on a garden hose when you do not want to buy a pressure washer. Choose the cannon if you have or will buy a pressure washer. Choose the gun if you want foam on a budget with no extra equipment. Foam washing is popular because it loosens dirt before you touch the panel, reducing scratch risk. But the two tools that apply the foam are not interchangeable. This guide compares them across the five factors that matter: foam density, pressure requirement, compatible equipment, cost and cleaning power.

A housekeeper and a custodian are buying different machines Before comparing specifications, picture the shift. A hotel housekeeper walks a corridor, enters a guest room, cleans around a bed and bathroom, and moves to the next room — the machine is on for short bursts, the route is interrupted by furniture, and guests may be on the other side of the wall. A school custodian cleans after hours, covers long corridors and open gym floors, and often works alone with the machine running continuously for an hour or more. Those two buildings pull the same "backpack vacuum" category in different directions. Hotels should weigh noise and working weight first, because a machine that disrupts a guest experience fails even if it cleans well. Schools should weigh filtration and endurance, because dust and allergen loads are higher and the shift is longer. This is why a specification sheet alone cannot rank machines — the building and the duty cycle must come first. The six specifications ...
