Compare the debris on your routes
Map grit, leaves, wet organic material, litter and other route debris. Ask each supplier which cases the proposed configuration handles and which it excludes. Use the comparison to shortlist systems before writing the full procurement and acceptance schedule.
Trial both sweepers on the debris they will collect
A sweeper that picks up dry grit may behave differently with bulky leaves or wet organic material. Include those materials and mixed litter in the route trial. Record the road surface and parked obstacles, along with the space available for the pickup equipment. Ask which materials fall outside each proposed system’s specification. The names “vacuum” and “mechanical” alone cannot rank their performance on every route.

| Trial case | Record | Decision |
|---|---|---|
| Collection path | Diagram showing suction pickup or broom and conveyor/elevator transfer into the hopper | Brushes can feed either system, so brush count does not identify the architecture |
| Fine grit on a dry section | Residual material, visible dust, water use, passes and elapsed working time | Check the agreed cleaning result; a result for one debris case does not establish performance on every route or season |
| Dust-control equipment | Water application, pickup enclosure and any filtration or air-management equipment actually offered | A specified particulate claim needs configuration-specific evidence; visible spray or appearance alone is not certification |
| Leaves and wet material | Pickup interruptions, blockage response and unloading | Confirm the material can pass through the installed collection path |
| Curbs and restricted street access | Pickup reach on representative uneven surfaces, parked obstructions and repeat maneuvers | Identify sections requiring another method; a clear demonstration lane can hide route gaps |
| Discharge at the receiving site | Material path, hopper discharge geometry and disposal-facility access | Confirm that the receiving site can accommodate the unloading arrangement |
| Wear and cleaning | Brush and pickup-path wear for vacuum proposals; broom and conveyor/elevator wear for mechanical proposals | Use the installed parts list and maintenance requirements, not a universal system-wide service schedule |
| End of shift | Hopper load, water remaining, cleaning and service time | Compare productive route time including refill and disposal travel |
Compare collection results on representative road sections
Bucher’s V65 and E35m illustrate different collection paths, not transferable KEEYAK capacities or environmental claims. Examine residual material, escaping dust, curb access, discharge and maintenance under the same trial conditions.

Show the debris cases and receiving facility. Record repeat passes, water use and elapsed working time with the collection result, and keep conclusions tied to the conditions actually tested.
Information to prepare for this review
- Representative debris types, dimensions, moisture and seasonal variation
- Road and curb condition, parking obstructions, gradients and access width
- Required collection result, including how residual material and escaped dust will be assessed
- Water supply, allowable operating conditions and discharge-site arrangements
- Working windows, nearby noise-sensitive locations and destination-specific requirements
- Workshop capability and access to brushes, pickup-path parts or conveyor components
Records to request and keep
- System description and illustrated material path tied to the quoted model
- Configuration schedule identifying standard equipment, options and excluded debris conditions
- Trial record with debris, surface, weather, speed, working width and number of passes
- Photographs or measurements of remaining material using the agreed comparison method
- Record of water use, hopper loading and time away from sweeping during the trial
- Discharge-site compatibility and documented operator access for routine checks
- Parts and maintenance comparison for the exact two offers, including local service arrangements
Common mistakes and what to check instead
- Calling every sweeper with rotating brushes mechanical: Identify the transfer mechanism after the brushes gather the material.
- Assuming vacuum, regenerative air and washing describe the same system: Ask for the actual airflow and collection arrangement; washing alone does not establish collection into a hopper.
- Choosing a universal winner from a brochure: Select by the priority debris cases and disclose any remaining route sections requiring another approach.
Scope of this guide
This comparison concerns pickup architecture, not a guarantee of cleaning rate or particulate compliance.
The linked catalog illustrates available inquiry routes; mechanical transfer equipment must be confirmed in a project quotation.
Restricted or hazardous debris requires the responsible operator to define a suitable collection and disposal method.
Sources and applicability
