Five mistakes to avoid when buying window cleaning equipment

A fitting that looks similar may have a different thread, hose size or pressure rating. Before ordering, record the exact model of the reel, pump, pole and connectors already in your setup.

• Check hose internal and external diameter, length and temperature rating.
• Match connector type and thread, rather than relying on a product photograph.
• Confirm mounting clearances and the electrical requirements of powered equipment.

Send photographs and model details to the supplier if a connection is uncertain. This is usually easier than adapting incompatible parts after delivery.

“Hard-water area” is useful context, but it is not a complete equipment specification. Measure incoming water, estimate the volume you need and compare consumable costs. TDS and water hardness are related concepts, not interchangeable measurements.

DI uses resin to remove dissolved ions. RO reduces dissolved solids before any DI polishing. A supply of already-purified water may suit a delivery-only setup. Read the RO and DI comparison before deciding.

A larger tank adds water weight and takes up vehicle space. A longer pole can add weight and handling demands. Buy for the work you can carry out safely and for the vehicle’s actual limits, not a headline capacity.

Measure the installation area, door clearances and service access. For tanks, include equipment, occupants and other loads in the payload assessment. For poles, consider the brush weight and working position as well as the stated reach.

Include installation, resin, filters, replacement parts, charging and routine maintenance in the comparison. Ask which parts are supplied and which are optional. A low initial price can be misleading if essential fittings or installation work are excluded.

• Check availability of the specific replacement parts you may need.
• Read the maintenance instructions before buying.
• Compare like-for-like specifications, VAT treatment and delivery arrangements.
• Keep a modest stock of compatible consumables rather than a box of unidentified fittings.

Pure-water equipment, traditional tools and specialist treatments serve different purposes. Follow the surface manufacturer’s instructions for coated glass and delicate materials. Do not put detergent into a pure-water system unless its manufacturer permits it.

Choose training, protective equipment and access methods from the job assessment. A harness is not a universal solution, and owning a longer pole does not make every window accessible.

Before checkout, review your list against the work, the water and the vehicle. Remove items that solve no identified problem, then confirm the remaining specification with the supplier.
