Vacuum cleaners are susceptible to impact damage that can cause cracks or breakage of plastic parts.
Hoses of cylinder cleaners may be used to pull the vacuum cleaner along, stretched to reach awkward places and bent around sharp corners. Latch mechanisms of upright cleaners experience repeated stress cycles which can cause fatigue fracture failure.
The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
No damage after bump test; 40,000 oscillations – no damage
Drop tests; test latch mechanism; 51,000 hose oscillations
62,000 hose oscillations
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Use impact resistant grades of plastics
Use, for example, ABS, PC/ABS or HIPS for mouldings to avoid impact damage and cracks due to cyclic fatigue.
