Tennant Co. Discontinues Sentinel Street Sweepers. Your Alternatives?

Citing operational support costs and declining customers and profit margins, Tennant Company announced the discontinuation of its Sentinel outdoor vacuum street sweeper and All-Terrain Outdoor Vacuum (ATLV) during its Q3 2019 Earnings Call on October 30th. This slimming of Tennant’s product lines follows a similar discontinuation from Q2 where it dropped the Green Machine sweepers and Orbio chemical dispensers from its catalog. During its Q3 call, the company detailed that its second strategic pillar specifically focuses on “reducing complexity and building scale across [its] products and operational and business processes.” In saying so, Tennant has all but confirmed that additional product discontinuations will follow in the near future.^{1, 2} This change in offerings will require its existing customers and potential new customers to find alternatives to the Tennant Sentinel Street Sweeper and ATLV, among other Tennant products. Furthermore, prospective Tennant customers may find themselves wary about buying a product which is liable to be discontinued at any time. It appears that Tennant Company will continue to increase its focus on its biggest sellers and most profitable products, such as its autonomous robot floor scrubbers, and, in doing so, gradually strip the less profitable items from its catalog.

Tennant Sentinel Outdoor Street Sweeper Alternatives

Dulevo D3 Street Sweeper

The Dulevo D3 is a purpose-built street sweeper of relatively compact size that’s able to navigate narrow streets and obstacles. Its components are built to have accessible parts that are easy to maintain. Another plus is its wide windows for excellent driver visibility. For fine particle and silica dust control, GORE filters are available which are rated for 99% filtration of PM10 particles. The Dulevo D3 also has an optional third broom which can be controlled to reach in any direction for greatly extended reach and access to small nooks and crannies. More Details

Dulevo D6 Street Sweeper

The Dulevo D6 has options for the same PM10 fine dust filtration and articulating third, front broom as the D3. Once again, high driver visibility and parts accessibility are top-of-the-line here. Compared to the D3, this model beefs up everything: a wider sweeping path, larger hopper, and higher dumping. More Details

It has a symmetrically situated cabin and large windows which provide very high visibility for the driver. The Dulevo 850 has an optional vacuum hose accessory to give it functionality that is similar to that of the Tennant ATLV. More Details

Dulevo D.zero² 100% Electric Mini-Sweeper

Similar to the Dulevo 850, the D.zero2 brings the same size advantages, maneuverability, and even bigger hopper and water tank capacities. Its real claim to fame is being a 100% electric sweeper with zero CO2 emissions and zero harmful gasses. Its electric motor also means that it runs extremely quietly and provides long-term savings in fuel consumption and maintenance costs. More Details
