Verdict

The LEHMANN Haddo Industrial Vacuum Cleaner is a versatile 3-in-1 wet, dry, and specialized ash suction appliance equipped with a high-performance 2000-watt motor and a durable 20-litre stainless steel collection tank. Key characteristics include an integrated blowing function, a dual-stage filtration setup featuring a washable HEPA filter that captures fine particles, a 1.5-metre reinforced metal hose, and a 3.5-metre power cable. Its main pros lie in its robust multi-surface capability to safely vacuum liquids, construction dust, and fireplace ash up to 45°C without requiring bags, alongside convenient maneuverability on stable caster wheels. On the downside, the device operates at a relatively high noise level of 82 decibels, which can be disruptive during prolonged indoor use.
