Maidaid Evolution 502 Undercounter Glasswasher With Drain Pump

The Maidaid Evolution 502 is a 500mm basket undercounter glasswasher designed for commercial bar and hospitality use. It sits beneath a standard counter, connects to a water supply and drain, and works through a straightforward four-button control fascia with an LCD display. A drain pump and break tank are included as standard, which removes the need for the machine to be positioned at floor drain level — a practical advantage in many existing bar layouts.

In service, the Evolution 502 handles steady glasswashing demand across pub bars, hotel bars, function rooms and smaller licensed venues. The parallel wash and rinse arm design helps deliver consistent wash coverage across the basket, and the triple filtration system — supported by stainless steel scrap tray filters — keeps water quality stable across multiple cycles without constant manual intervention. The double-skinned construction keeps noise and heat output lower than comparable single-skin machines, which matters in customer-facing environments.

From an operational standpoint, the machine has been designed with realistic end-of-shift use in mind:

• Automatic end-of-service self-clean reduces manual cleaning time after busy periods
• Peristaltic dosing pumps for detergent and rinse aid maintain accurate chemical use throughout service
• Selectable energy-saving mode reduces running costs during quieter periods
• Thermostop function ensures rinse water reaches effective sanitising temperatures
• Multiple cycle options allow wash times to be adjusted to suit glassware type and soil level

The Evolution 502 requires a plumbed cold water inlet, a drain connection, and a suitable electrical supply. The inclusion of a break tank means it meets water authority requirements without a separate backflow prevention device. Installation should be carried out by a qualified plumber and, where required, a registered electrician. Because it is an undercounter unit, available height clearance beneath the counter needs to be confirmed before ordering.

This model suits venues with moderate to busy glasswashing demand — typically pub bars, hotel bars, cafés with licensed service, and smaller function facilities. For very high-volume operations running back-to-back service across large glass counts, a larger-capacity pass-through or rack conveyor machine may be a more practical fit. For quieter sites, lighter-duty options at a lower price point are also available.
