The single most common mistake in parts washer purchasing is buying a machine that is too small — either because the buyer sized for typical parts instead of the largest part they occasionally need to clean, or because throughput requirements grew after installation. Sizing a parts washer correctly from the start is straightforward if you work through four questions in order: What is the biggest part? How heavy is the heaviest load? How many parts per shift? And how much manual involvement is acceptable? This guide also pairs with the interactive how-to-choose page on the Magido website.
Step 1: Measure Your Largest Part
The most basic sizing question is the physical envelope of your largest part — the maximum length, width, and height of the biggest component you will ever need to clean. That part must fit inside the wash cabinet or conveyor opening with clearance on all sides. On a spray cabinet washers, this means the part fits on the turntable with room for the spray nozzles to reach all surfaces. On a conveyor washers, the part must pass through the tunnel opening without touching the belt sides or spray headers. Always size for your largest occasional part, not your typical part — the machine that cannot handle your largest part is useless when you need it.
Step 2: Check Weight Capacity
Magido spray cabinet washers range from 330 lbs on compact X81 models up to 5,000 lbs on the largest X53/2 front load machines. Do not just weigh a single part — consider the total weight when the turntable is fully loaded with a production batch. Exceeding weight capacity stresses the drive motor, wears the turntable bearing prematurely, and in severe cases can damage the machine structure. For heavy components like engine blocks and transmission housings, see the front load washers category.

Step 3: Calculate Your Throughput Requirement
Throughput is the number of parts you need to clean per shift or per hour. For spray cabinet washers, cycle time is typically 5 to 20 minutes. Divide your required parts per shift by the available production time to find the minimum cycle rate. If you need to clean 120 parts per 8-hour shift, you need a cycle every 4 minutes — which is aggressive for a single cabinet. At that volume, an conveyor washersin-line belt or multiple spray cabinets is a more practical answer. See the in-line belt conveyor washers category for continuous high-volume options.
Step 4: Choose the Right Machine Type for Your Volume
manual washers handle one-off parts and very low volumes. top load washers cover the widest range of mid-volume applications. Front load spray cabinets handle the same range for larger, heavier components. conveyor washersin-line belt are the right choice when throughput exceeds what a cabinet can deliver. rotary drum washers handle small loose parts in bulk where individual loading is impractical.

Step 5: Decide on Automation Level
Automation level determines how much operator involvement the washing process requires. A manual washers requires hands-on operator involvement throughout. A spray cabinet automates the wash cycle — load, start, return to unload. A conveyor washers automates everything continuously. A rotary drum washers automates bulk small-part processing end to end. Higher automation reduces labor cost per part and removes process variability. Use the free process evaluation on our contact page to get a specific model recommendation for your operation.
Magido Can Help You Size It Correctly
If you have your part dimensions, weights, throughput requirements, and contamination types ready, Magido will recommend the specific model that fits your application — at no cost and with no obligation.
